Security Dealer Attrition Rates: What's Normal, What's Healthy, and How to Beat It in 2026

After 23 years in this industry — I founded and ran Protect America, created 800,000+ customer accounts, and did over $600 million in sales — I can tell you attrition is the number that separates dealers who build wealth from dealers who run in place. The industry-typical range for annual account attrition is around 10–13%. If your book holds under 10%, you're healthy. If you're above 13%, you don't have a growth problem — you have a leak, and pouring more marketing into a leaking bucket is the most expensive mistake in this business.

One honest caveat: measure it before you quote it. Plenty of owners tell me "we hardly lose anyone" and have never actually divided cancellations by their starting account count. Gut feel runs about half of reality, every time.

Keep the math simple and consistent: accounts lost during the year, divided by accounts at the start of the year. A few rules keep you from fooling yourself:

• ▸Count every terminated account — moves, non-pay cancellations, and takeovers by competitors all count. Only true relocations where you keep the account (new owner signs on) don't.
• ▸Track it monthly and annualize. A bad quarter shows up months earlier in the monthly number.
• ▸Track RMR attrition alongside account attrition. Losing your $60/month interactive customers while keeping $25 legacy landline accounts is worse than the account count suggests.
• ▸Segment it: residential vs commercial, under-2-years vs over-5-years, by ZIP code. The blended number hides where the leak actually is.

Here's the part that changes owner behavior once it sinks in. Monitoring account books trade at 30–50x monthly RMR. A $40/month account you keep isn't just $480 a year of revenue — it's roughly $1,200 to $2,000 of enterprise value sitting on your books. Lose a hundred of those a year unnecessarily and you've quietly shredded six figures of exit value, on top of the growth you had to buy just to stand still. And remember the front-end math: industry-typical numbers say it takes 30–40+ months of RMR to recoup the cost of creating an account. An account that cancels in month 20 never paid you back at all. Retention isn't a customer-service nicety. It's the highest-margin activity in your company.

Notice the pattern: only the move is genuinely out of your hands, and even that one has a partial answer. The rest are operating discipline.

Nobody cancels because their alarm works. They cancel because a zone kept faulting, they called twice, and nobody called back. Service failure is the most fixable cause on the list and the one that does the most brand damage on the way out. Set a hard internal standard — service requests acknowledged same day, scheduled within the week — and instrument it: missed-call text-back on the service line, automatic follow-up after every closed ticket asking "is it actually fixed?" A customer who watches you take their problem seriously becomes more loyal than one who never had a problem.

The average canceled customer heard from their alarm company exactly as many times as their bill arrived: twelve times a year, all invoices. Then a competitor's door-knocker showed up with a friendly face and a takeover pitch, and the relationship you thought you had turned out not to exist. The counter costs almost nothing: a check-in call or text twice a year, a battery-and-test reminder, a note when they've been with you five years. Automate the touches through your CRM so they happen without heroics. Customers don't leave companies they feel connected to — they leave companies they forgot they were paying.

When a customer calls quoting a competitor's lower price, the worst move is instant surrender — dropping your rate ten dollars teaches customers that loyalty is for suckers and trains your book to shop you every year. The better sequence: thank them, review the account, and respond with value before price — a service credit, an equipment refresh, an upgrade to interactive features — and only then, if needed, a modest concession tied to a term renewal. And hold the line on annual increases for the rest of the book. A book with disciplined rates and sub-10% attrition is worth dramatically more to a buyer than a discounted book of shoppers.

The stickiest accounts aren't the ones under the longest contracts — they're the ones using the system every day. Interactive services changed retention economics permanently:

• ▸App control, video, and doorbell integration turn a wall panel nobody touches into a daily habit — and habits don't cancel.
• ▸Cameras and video verification give customers something they'd visibly lose by switching.
• ▸Smart-home add-ons (locks, thermostats, garage) multiply the switching cost with every device.
• ▸Upgrade your legacy accounts deliberately: an old keypad-only customer is your most cancellable account and your best upsell at the same time.

Every cancellation request should hit a defined save process before it's processed — not a shrug and a confirmation email. That means one trained person (in a small shop, probably you) who calls back within a day, asks why, and has real authority: a service visit at no charge, a rate adjustment tied to renewal, an equipment upgrade. A meaningful share of cancellations are save-able because most of them were never about wanting less security — they were about feeling unimportant. Track your save rate monthly like you track installs. It's the cheapest RMR you'll ever acquire.

One more modern leak worth checking: when your customers' neighbors ask ChatGPT or Google who to use, the companies that get named are the ones taking over your accounts. Retention and visibility are two sides of the same fight.
