- A monitored home security system typically earns a 2% to 15% homeowners insurance discount, depending on features and monitoring type.
- On the roughly $2,400 average annual premium, that is about $48 to $360 a year back in your pocket.
- Professionally monitored systems tied to a central station earn the biggest discounts. Self-monitored DIY setups often earn little or nothing.
- The discount rarely covers the full monitoring bill, so buy the system for protection first and treat the insurance credit as an offset.

Priya’s insurer offered her a 5% discount for adding a monitored security system. Her annual premium is $2,300, so the credit works out to $115 a year. The professionally monitored system she was quoted costs $45 a month, or $540 a year. She wanted to know the honest answer to one question: does the discount pay for the system, or is she fooling herself?
That is the reality most sales pitches skip. The insurance discount is real money, but it is a partial rebate on your monitoring cost, not a free system. Here is how the numbers actually break down.
How big the insurance discount really is
Most insurers offer a discount for a security system, but the size swings widely based on what the system does. A basic burglar alarm might earn 2% to 5%. A comprehensive system that monitors burglary, fire, and water, and reports to a professional central station, can earn 10% to 15% with some carriers.
Put that against the average U.S. homeowners premium, which sits near $2,400 a year in 2026 and keeps climbing. A 2% discount is about $48 a year. A 5% discount is roughly $120. A 15% discount is around $360. That range is the whole story: the difference between a token credit and a meaningful one comes down to how robust and how monitored your system is.
One rule holds across every carrier. You only get the discount if you report the system and provide proof. Which brings us to the single most common mistake homeowners make here.
Call your insurer, ask exactly which system features qualify, and send them the certificate of monitoring your provider issues. A system already on your wall earns you nothing if the carrier does not know it exists.
What the system costs against what you save
Now the math that decides everything. Line up the annual insurance savings against the annual cost of running the system.
| Cost or saving | Typical low end | Typical high end |
|---|---|---|
| Annual insurance discount (on ~$2,400 premium) | $48 (2%) | $360 (15%) |
| Professional monitoring, per year | $120 ($10/mo) | $720 ($60/mo) |
| Equipment, spread over 5 years | $40/yr ($200 kit) | $300/yr ($1,500 kit) |
| Net annual cost after the discount | Roughly $112 | Roughly $660 |
The takeaway is blunt. Even in the best case, the insurance discount offsets part of your monitoring cost, not all of it. If you were never going to pay for monitoring, the discount alone will not make a system free. But if you want the security anyway, the discount shaves real money off the running cost. Our breakdown of the real cost of a home security system covers the full price picture beyond just monitoring.
DIY vs professionally monitored: the discount gap
This is where a lot of homeowners get surprised. The cheap DIY route often earns the smallest insurance discount, or none at all.
Insurers care about response, not gadgets. A camera that only pings your phone does nothing if you are asleep or out of signal. A professionally monitored system connects to a central station staffed around the clock, and that station dispatches police or fire. That verified response is what carriers reward. A self-monitored DIY system with no central station may earn a token discount or fail to qualify entirely.
That does not make DIY the wrong choice. It saves on hardware and avoids a contract, and for many homes the protection is enough. Just do not buy a self-monitored kit expecting a big insurance credit. If the discount matters to your math, you likely need professional monitoring.

The verdict: when it pays and when it doesn’t
Buy the system for protection, not for the insurance discount. That is the honest verdict. The discount is a welcome offset that can cut your net monitoring cost by 20% to 50%, but it rarely makes the system pay for itself.
The math tips in your favor in two cases. First, if you were going to pay for monitoring anyway, the discount is pure upside, so claim it and document it. Second, if your insurer offers a high-end 10% to 15% credit and you choose a modest monitoring plan, the discount can come close to covering the monitoring bill. Before you sign anything, ask your insurer for the exact discount in dollars, then compare it against the plan you actually want. And while you are on the phone, ask about the other credits in our guide to lowering your homeowners insurance premium, because a security discount rarely moves the needle alone.

How much does a home security system lower my insurance? Most homeowners see a 2% to 15% discount on their premium. A basic alarm earns the low end, while a professionally monitored system covering burglary, fire, and water earns the high end. On the average $2,400 annual premium, that is roughly $48 to $360 back per year.
Do I have to tell my insurer about my system? Yes, and you have to prove it. The discount only applies once you report the system and send your insurer a certificate of monitoring. A system the carrier does not know about earns you nothing, so call and ask which features qualify.
Does a DIY system like a self-monitored camera kit get the discount? Often not, or only a small one. Insurers reward verified professional monitoring that dispatches emergency responders, not cameras that only alert your phone. If the insurance credit is important to you, you likely need a professionally monitored plan.
Will the insurance savings pay for the monitoring fee? Rarely on their own. The discount usually offsets 20% to 50% of your annual monitoring cost. Treat it as a rebate that lowers the price of protection you wanted anyway, not as a way to get a free system.
Which system features earn the biggest discount? Central-station professional monitoring is the biggest driver, followed by combined burglary, fire, and water-leak sensors. Ask your specific insurer for its qualifying list, since the exact percentages and eligible devices vary from one carrier to the next.
