Estimate how long a homeowners insurance discount takes to offset what you spend on a system.
Some homeowners insurance companies offer a discount on premiums for a monitored burglar or fire alarm system, and the size of the discount varies by insurer, state and the type of monitoring. Ask your agent for the exact figure in writing. This calculator shows whether that discount could ever repay what you spend.
Enter the total cost of the system, any rebate or credit you receive, and your yearly savings. For an honest result, define yearly savings as the insurance discount minus the monitoring fees you will pay, because a monitoring plan can easily cost more per year than the discount saves. If that number is negative or zero, the system will not pay for itself through insurance alone, which is common and not a reason to skip security if safety is your goal.
Worked example (illustrative): a system costing 800 dollars with yearly net savings of 120 dollars has a simple payback of 800 / 120, about 6.7 years, before the small yearly change is applied.
Limits: The calculator ignores the value of safety, theft losses avoided and resale appeal. Treat it as one input, not the decision.
