Most people who type “ADT cost per month” want one number. ADT doesn’t really have one. It now sells two separate products under one name: a professionally installed system priced through a sales consultation and tied to a multi-year agreement, and a do-it-yourself line called ADT Blu that runs month to month. The monthly charge can land anywhere from about ten dollars to sixty dollars and up, depending on which side of that line you are standing on, whether you have cameras, and what your city charges for alarm permits.
This guide does the arithmetic a sales call usually skips. It covers what each plan actually costs over a full contract, what it costs to leave early, which fees sit outside the advertised price, how ADT compares with Ring, SimpliSafe and Vivint once you add everything up, and the specific situations (renting, inheriting an old ADT panel, signing at the front door, caring for a parent who lives alone) where the right answer changes.
Eight Straight Answers Before You Call ADT
These are the questions that decide whether ADT fits your budget. Each one gets a short answer here and a full explanation further down.
ADT Blu’s Pro-Protect plan at $24.99 a month, month to month, for a self-installed system without cameras. It is the only ADT path where a monitoring agent will call police or fire for you at that price.
It is quoted per home. The offer ADT has posted this fall pairs a $99 installed system with a 36-month agreement at $59.99 a month. Independent reviewers put Pro Install monitoring at $49.99 and up. ADT’s reactivation deal for homes with an existing panel starts at $45.99.
Self-installed ADT Blu costs nothing to install, only the kit price ($199 to $699 at list). Professional installation typically adds $100 to $200, though promotions like the current $99 system bundle the technician visit into the price.
On a 36-month contract, ADT may charge 75% of the remaining monthly fees. Cancel six months into a $59.99 plan and that is about $1,350. ADT Blu has no early-exit fee because it has no term.
No. Ring’s Pro plan, which includes professional alarm monitoring and video features for every device at one address, is $19.99 a month or $199.99 a year. ADT’s closest equivalent with cameras, Blu Pro-Protect with video, is $34.99.
Yes. ADT’s own terms say it adds $8 a month where a city requires guard verification before police respond, and passes along your alarm permit cost plus an $8 processing fee where it must get the permit. Sales tax, equipment financing and the optional QSP warranty are separate lines too.
Usually, if you act fast. The FTC’s Cooling-Off Rule gives you three business days to cancel a sale of $25 or more made in your home, even if the system has already been installed. Cancel in writing and keep proof of the date.
Not quite. ADT’s terms limit it to system problems ADT tries and fails to fix within six months, and they require you to have paid for both professional monitoring and the QSP warranty plan the whole time. Disliking the service is not covered.
What ADT Costs Per Month, Plan by Plan
The single most useful thing to know before comparing prices: ADT Blu and ADT Pro Install are different systems. Their equipment is not interchangeable, their contracts work differently, and their monthly prices sit in different bands.
ADT Blu launched on May 20 as a self-installed system managed through the ADT+ app, sold through ADT’s website, phone sales and Amazon. ADT describes it as having no long-term contract and lets you switch between watching alerts yourself and paying for 24/7 monitoring. ADT’s own fine print notes that Blu devices only work with Blu systems, so a Blu camera will not join a professionally installed ADT setup later.
ADT Pro Install is the traditional product: a technician visits, Google Nest cameras and doorbells are the video hardware, and pricing comes out of a consultation rather than a public price list. When we went through ADT’s posted residential terms line by line, every professionally installed offer we found was built on a 36-month monitoring agreement, with a 24-month version for California customers.

The lines that show up on the bill but not in the ad
The monitoring rate is only the first line. ADT’s residential terms page lists several charges that can sit on top of it, and they matter more on a tight budget than the headline difference between two plans.
This trips people up when they move or cancel. With ADT Blu you buy the kit outright. With professionally installed systems, ownership depends on how the deal is structured. ADT’s reactivation offer states plainly that the professionally installed system remains ADT’s property. Reviewers report that if you pay for Pro Install equipment up front, ADT requires only one month of monitoring. Ask the consultant one direct question and get the answer on paper: “When this agreement ends, who owns the panel and sensors?”
Equipment and installation prices
ADT Blu kits are priced publicly. At list, the Build My System starter (base station and two door/window sensors) is $199, the Security Starter Kit is $249, the Life Safety Kit with a smoke and carbon monoxide detector is $279, Video Essentials with one camera is $339, Outdoor Video with a doorbell and an outdoor camera is $389, and the Total Safety Kit is $699. ADT runs deep sales on these; a 60% off promotion ran through October 21, so if you are shopping a day or two later, check whether a new one has replaced it before paying full price.
Pro Install packages are quoted, but reviewers who went through ADT’s consultation recently reported package prices from about $349 for a Security Starter to roughly $1,594 for a Total Safety system, with financing up to 60 months on systems of $599 or more. Professional installation usually adds $100 to $200. Nest cameras sold through ADT run roughly $99 to $279 each.
ADT Security Cameras: The Monthly Cost of Adding Video
Cameras are where ADT bills climb fastest, because adding even one usually moves you to a higher monitoring tier rather than adding a small per-camera charge.
On ADT Blu, the arithmetic is simple. A camera on its own, with no sensors, runs on the $9.99 Video Connect plan, which includes cloud recording but leaves you to respond. Put a camera on a system that has door sensors and you want professional monitoring, and the plan moves from $24.99 to $34.99, a $10 monthly jump, or $120 a year, for the video features. Reviewers report Blu’s paid plans keep about 30 days of recordings in the cloud.
On Pro Install, the cameras are Google Nest hardware and the camera-capable tier is the top one. Reviewers report it bundles Google Home Premium, the subscription formerly called Nest Aware, which on its own costs $10 or $20 a month directly from Google. That bundling softens the price gap a little if you were going to pay Google for video history anyway. It also lets ADT’s monitoring center look at camera footage to verify an alarm before dispatching, which can matter in cities that are strict about false alarms.
If you only want to see who is at the door and get a clip when a package is taken, you are paying for video storage, not alarm monitoring. A camera-only plan from ADT Blu at $9.99, or Ring’s $4.99 single-device and $9.99 whole-home plans, does that job for a fraction of a full monitoring bill. Pay for the higher tier only if you want sensors and cameras working together with someone else responding.
The Three-Year Total: What You Actually Pay
Monthly prices hide the real comparison. A $35 difference per month is $1,260 over a standard ADT agreement. Here is each option worked out over 36 months, using list equipment prices and the entry professional-monitoring plan.
Two things stand out. First, monitoring, not equipment, is most of the money in every scenario. Even the $699 Blu Total Safety kit costs less than one year of the professionally installed plan’s monitoring. A big equipment discount at signing can be offset many times over by a monthly rate that is $20 or $30 higher. Second, ADT Blu lands within roughly $50 to $190 of Ring, SimpliSafe and Vivint over three years for a sensor-only system, so for buyers who want the ADT monitoring network specifically, Blu has made ADT far more competitive than it used to be.
The professionally installed offer is in a different price band altogether. It buys you someone else doing the setup, Nest camera integration, ADT-arranged video verification, and the convenience of one company handling everything. Whether that is worth roughly $1,100 more than a Blu system over three years is a personal call, but it should be a deliberate one.
The Contract, the Guarantee, and What Leaving Costs
For professionally installed ADT, the contract terms move more money than the plan you pick. Here is the life of a typical agreement, with the windows that let you out cheaply.
How the early termination fee is calculated
ADT’s terms say that if you end a 36-month agreement early, ADT may charge 75% of the monthly service charges due for the rest of the initial term. That is a straight line downward over time. On a $59.99 plan, leaving on day one would cost about $1,620. After a year it is about $1,080. With six months left, about $270. The chart and calculator below let you see your own number.
The 6-month money-back guarantee, read closely
ADT markets its guarantee prominently, and it is real, but narrower than the name suggests. According to ADT’s posted terms, it only applies after ADT has tried and failed to resolve a system-related issue within the first six months of your original activation. It requires that you bought and kept paying for both professional monitoring and QSP (ADT’s Quality Service Plan, an extended limited warranty) from the first day. The equipment must be returned before a refund is processed, the problem cannot have been caused by you, and the guarantee cannot be transferred.
The practical lesson: if you are counting on the guarantee as a safety net, add QSP at signing and keep a written log of every service call, with dates and ticket numbers, from week one. Without that paper trail, a dispute in month five becomes your word against a call-center record.
If an ADT dealer or rep sold you the system in your home, the FTC’s Cooling-Off Rule applies to purchases of $25 or more. You have until midnight of the third business day after the sale to cancel for any reason, and the FTC says this holds even if the system has already been installed. Sundays and federal holidays do not count. The seller is supposed to give you a cancellation form at the sale. Sign and date it and mail it, ideally by certified mail, or deliver it in person and get a signed receipt. A phone call alone is risky because it leaves no proof.
You may have read that a federal rule now forces companies to let you cancel as easily as you signed up. The FTC finalized that rule in 2024, but a federal appeals court vacated it in July 2025 on procedural grounds before it took effect. The FTC opened a fresh rulemaking on its Negative Option Rule in 2026, and consumer groups are pushing for a cancel provision, but nothing equivalent is in force nationally today. In practice, reviewers report that professionally installed ADT must still be canceled by phone. ADT Blu is different: its terms let you cancel by calling the Blu line or following the instructions in your order confirmation email, and the free first month can be canceled from the billing tab of the ADT+ portal.
Consumer reporting and complaint threads describe mid-contract increases, and a California county prosecutor once sued ADT arguing customers should be told how large such increases could be. Read the rate-change clause in your own agreement before signing, and ask the consultant to write the locked rate, if any, onto the contract itself. Reviewers have argued the reverse is also true: a long agreement can shield you from list-price increases on new plans. Which way it cuts depends entirely on the wording you sign.
Which Situation Sounds Like Yours?
Average prices are less useful than knowing what people in your exact position usually end up paying, and where they get caught out.
This is where professionally installed ADT makes the most sense, because a 36-month agreement is not a trap if you were going to stay anyway. Get two written quotes: one Pro Install, one ADT Blu priced out at the same sensor count. If the Pro Install quote is more than about $25 a month higher, decide what that buys you in concrete terms, such as Nest camera integration, a technician who mounts everything, or video-verified dispatch. If those things are not worth roughly $900 over three years to you, Blu gets you the same monitoring network for less.
Skip any multi-year agreement. Leaving a 36-month contract after a year on a $59.99 plan could mean a bill around $1,080 if ADT’s relocation program doesn’t fit your new address. ADT Blu is designed for this: sensors stick on with adhesive, there is no term, and the kit moves with you. Check your lease before drilling or mounting a doorbell camera, and ask the landlord whether the building already has a monitored system you would duplicate.
ADT advertises a free virtual reactivation for existing systems, starting at $45.99 a month for its Secure monitoring service on a new 36-month agreement, with $99 off the activation and test. Not every system qualifies, and ADT’s terms say the reactivated professionally installed system remains ADT’s property. Before agreeing, ask how old the panel and communicator are; older panels may need replacement, and a “free” reactivation that leads to a paid equipment swap changes the math. If you want no contract, removing the old hardware and starting fresh with Blu may be cheaper over three years.
Many ADT systems are sold by authorized dealers rather than ADT itself, and terms can differ. Consumer news reports have described homeowners who learned only when canceling that a local dealer, not ADT, sold the contract, and that leaving would cost over $1,000. If you signed in your home in the last three business days, use the Cooling-Off Rule now. If it has been longer, find out who actually holds your contract (ADT keeps a dealer lookup on its website), read the term and termination clause, and ask whether the six-month guarantee was written into your agreement.
The deciding feature here is who responds when no one answers the phone, which favors professional monitoring over self-monitoring. A self-monitored plan only sends alerts to the app user, and ADT’s terms say plainly that on Self-Protect, ADT will not contact emergency responders. Add monitored smoke and carbon monoxide detection, since fire and CO are risks an older adult may not be able to react to quickly. ADT has advertised a 5% monitoring discount for AARP members and 10% for USAA members; ask whether either is currently offered. Put a second emergency contact on the account so a family member gets the call too.
Professionally installed ADT is the one route that ties Nest cameras and doorbells into a monitored alarm with ADT agents looking at the footage, and its top plan reportedly bundles the Google Home Premium subscription you might already pay for. Price what you spend on Google Home Premium today and subtract it from the ADT quote to see the true increase. ADT Blu does not use Nest cameras, so if Nest integration is the reason you want ADT, Blu will not deliver it.
Monitoring plans are tied to one address with every major provider; Ring, for example, requires a separate plan for each location. An empty house is where professional monitoring and water-leak or temperature sensors earn their keep, since a burst pipe in January can cost more than three years of monitoring. A month-to-month Blu system lets you run Pro-Protect during the months the house sits empty and drop to self-monitoring when you are there.
Many cities require an alarm permit, charge fines after a set number of false alarms, or require someone to verify an alarm before police respond. ADT’s terms say that in municipalities requiring guard verification it adds $8 a month, and where it must obtain your permit it passes along the permit cost plus an $8 one-time processing fee. Call your police department’s non-emergency line or check the city website for the alarm ordinance before you sign; a $96-per-call false alarm fine, the level Phoenix has charged, can wipe out a year of savings from choosing a cheaper plan.
ADT Blu Pro-Protect at $24.99 fits, with a few dollars to spare for tax. Buy the smallest kit that covers your real entry points (front door, back door, and a motion sensor covering the main hallway handles most single-story homes) during a sale, and skip cameras for now; adding one moves you to $34.99. If the ADT brand is not important to you, Ring’s $19.99 Pro plan or SimpliSafe’s $22.99 Standard plan leave more room in the budget.
ADT disclosed in an August 2024 SEC filing that attackers accessed databases with customer order information, including email addresses, phone numbers and postal addresses, and said it had no reason to believe card or bank data was taken. A separate filing that October described an intrusion involving encrypted employee account data. Neither filing said alarm systems were compromised. The practical risk is targeted phishing: treat any unexpected “ADT” call, text or email about billing or upgrades as suspect, and use a unique password plus two-step verification on your ADT+ account.
ADT vs Ring, SimpliSafe and Vivint, Once You Add It All Up
“ADT vs Ring” is the comparison people search most, and it is really a question about how much you value ADT’s own monitoring network over a lower bill.
Ring’s current plan lineup, as shown on its own site, runs from Ring Solo at $4.99 a month for one camera, to Ring Multi at $9.99 for every device at one address, to Ring Pro at $19.99 a month or $199.99 a year. Ring Pro is the tier with 24/7 professional alarm monitoring, cellular backup for Ring Alarm, and its AI video features. A Virtual Security Guard plan with live agents watching cameras costs $99 a month. One difference Ring states openly: it does not own its monitoring center. ADT runs its own monitoring centers, which reviewers consistently cite as the main reason to pay more.
SimpliSafe’s professional plans now start at $22.99 for Standard and $32.99 for Core, after increases in 2025, with Pro and Pro Plus at $49.99 and $79.99 adding live-agent camera deterrence. Vivint starts at $24.99 a month on a three-year contract, or $29.99 if you buy the equipment outright, and its camera-heavy packages run to about $57 a month.
| Provider | Pro monitoring from | With cameras | Contract | Watch for |
|---|---|---|---|---|
| ADT Blu | $24.99 | $34.99 | Month to month | Blu-only devices; no Nest cams |
| ADT Pro Install | ~$45.99–$59.99 | Top tier, quoted | 36 months (24 CA) | 75% early-exit fee |
| Ring | $19.99 | Included in Pro | Month to month or annual | Outsourced monitoring center |
| SimpliSafe | $22.99 | $32.99 (Core) | Month to month | Standard has no video recording |
| Vivint | $24.99 | Up to ~$57 | 36 mo if financed | $29.99 without contract |
Choose Ring if your home is already full of Ring cameras or Alexa devices and the lowest bill matters most. Choose SimpliSafe if you want a self-install alarm with a broad range of plan tiers and no contract. Choose ADT Blu if you want ADT’s own monitoring centers without a long commitment and can live without Nest cameras. Choose ADT Pro Install if you want a technician, Nest integration and one company handling everything, and you are certain you will stay put for the full term.
Is ADT worth it?
It helps to start with the risk you are paying to reduce. FBI figures for 2024 showed burglary down 8.6% from the prior year, and the national property crime rate fell to its lowest level since 1961. That does not make any one house safe, and burglary rates vary widely from state to state, but it does mean the strongest case for monitoring today is often fire, carbon monoxide, water damage and a quick response when you are away, rather than break-ins alone.
ADT’s scale is real. Its June quarterly filing reported about 6.1 million monitoring subscribers, and the company told investors it planned to push ADT Blu harder through Amazon in the second half of the year. Reviewers consistently rank ADT’s monitoring among the best they have tested. Complaints cluster in a predictable place: contract length, early-exit fees, and dealer sales practices. If you go in knowing the exit math above and get the important promises in writing, ADT can be worth it. If you are uncertain about staying, it usually is not, at least not on a long agreement.
Ways to Pay Less for ADT
ADT prices move with promotions and negotiation more than most people realize. These are the levers that tend to matter.
Since monitoring is most of the three-year cost, a $5 cut in the monthly rate saves $180 over 36 months, while a “free camera” saves its retail price once. Ask the consultant whether a lower monitoring tier covers your equipment, whether an affinity discount such as AARP or USAA applies, and whether enrolling in automatic payment changes the rate. Get the final number written on the agreement.
ADT’s own terms say only that some insurers offer discounts and that you should consult yours. The Insurance Information Institute has said most carriers offer some alarm discount, and an older industry survey of large insurers found discounts reaching as high as 20% for monitored systems. Call your carrier with two questions: how much the discount is for a professionally monitored system versus self-monitored, and what proof they need. ADT can usually provide an alarm certificate.
Reviewers have tracked ADT’s biggest equipment discounts around Black Friday and in recurring promotions throughout the year. Blu kits have recently been sold at 60% off; the current professionally installed $99 system offer is posted through November 9. If you are not in a hurry, waiting a few weeks for the next promotion is often worth it, but only if the monthly rate stays the same.
Life safety monitoring and cameras each push you up a tier. Smoke and CO monitoring is often worth it, particularly for older adults or homes that sit empty; video recording often is not, if your existing doorbell camera already covers the front door on its own cheap plan. QSP is worth buying only if you intend to rely on the six-month guarantee or expect service visits.
Door-to-Door Pitches, Fake Upgrades and Phishing
Home alarm sales have a long history of high-pressure tactics, enough that the FTC and several state attorneys general publish specific warnings about them.
A rep who says your current alarm company has gone out of business and they have taken over your account. A visit to “upgrade” or “replace” your existing system that turns out to be a new system with a new long-term contract. A pitch built on a sudden crime spree in your neighborhood and a deal that ends today. The FTC advises asking for identification before letting anyone in, checking the company with your state attorney general and consumer protection office, and knowing exactly who will monitor the system and how often you will be billed.
If someone claims to be from your existing provider, hang up or close the door and call the number printed on your bill. Legitimate companies schedule service visits in advance.
Common ADT Billing Problems and What to Try First
Most disputes fall into a handful of patterns. A little preparation usually gets a faster answer than a long call.
| What you notice | Most likely cause | Try this first | Then |
|---|---|---|---|
| Bill higher than the quote | Guard fee, permit, QSP, financing or tax | Match each line to your agreement | Ask which clause allows the charge |
| Rate went up mid-term | Rate-change clause in the agreement | Find the clause and the notice date | Ask for reversal or a penalty-free exit |
| Fine from the city | False alarms or missing permit | Check the ordinance and your permit status | Ask ADT for the alarm log |
| Can’t cancel online | Pro Install agreements go by phone | Call, note the rep and confirmation number | Follow up in writing |
| Moving house | Agreement tied to the old address | Ask about ADT’s moving program in writing | Compare against the exit fee |
| Still billed after canceling | Notice period or missed confirmation | Send your confirmation number in writing | Card dispute; state AG complaint |
When you call, have your account number, the date you signed, and a photo of the agreement’s first page ready. Ask the representative to repeat back any concession and give you a reference number. If a moving offer requires signing a new multi-year agreement, which is how ADT’s relocation deals have commonly worked, compare the total of that new term against the one-time exit fee before you agree; sometimes paying the fee and switching to a month-to-month product is cheaper.
Our Verdict on ADT’s Monthly Cost
You want ADT’s own monitoring centers responding to alarms, and either you will stay put for the full agreement (Pro Install) or you are happy installing a kit yourself (Blu). For many households, ADT Blu Pro-Protect at $24.99 is now the sweet spot: the same brand of monitoring without the long contract that defined ADT for decades.
A door-to-door rep is offering free equipment in exchange for a long agreement, you are inheriting an old ADT panel, or your city has strict permit and false-alarm rules. Each of these can quietly add hundreds of dollars over the life of the contract.
You rent, might relocate, or the monthly payment would strain your budget if your circumstances changed. The early-exit fee is the single biggest financial risk in an ADT purchase, and the month-to-month options remove it entirely.
Questions people still ask
How much is ADT per month for a basic system?
ADT Blu Pro-Protect is $24.99 a month for a self-installed system without cameras, with no long-term contract. A basic professionally installed system is quoted individually; current offers are built around $45.99 to $59.99 a month on a 36-month agreement.
Does ADT have a monthly fee without monitoring?
ADT Blu requires a plan: $9.99 for camera-only Video Connect or $14.99 for Self-Protect, where alerts go to your phone and ADT does not call responders. Professionally installed systems are sold with professional monitoring; reviewers report that if you pay for equipment up front, only one month is required.
How much does ADT charge to install?
ADT Blu is free to install because you do it yourself. Professional installation usually adds about $100 to $200, though promotions such as the current $99 installed system fold the visit into the price.
How long is an ADT contract?
Professionally installed agreements are 36 months in most states and 24 months in California. ADT Blu is month to month with a one-month minimum.
What is ADT’s cancellation fee?
On a 36-month agreement, ADT may charge 75% of the monthly service charges remaining in the initial term. After the term ends, reviewers report service continues month to month and can be canceled with notice and no fee.
Is ADT more expensive than Ring?
Yes. Ring Pro, which includes professional alarm monitoring, is $19.99 a month. ADT Blu’s professional plans run $24.99 to $37.99, and professionally installed ADT costs more again. ADT’s argument for the difference is that it runs its own monitoring centers.
Are there extra ADT fees in some cities?
Yes. ADT’s terms say it adds $8 a month where a municipality requires guard verification, and charges the cost of your alarm permit plus an $8 processing fee where it must obtain the permit. City false-alarm fines are separate.
