Home Security System ROI Calculator
Net benefit of home security system after insurance discount and risk reduction value
Calculate home security system ROI including insurance discount and burglary risk reduction value — what the system actually returns annually.
What this tool does
This calculator models the financial outcome of installing a home security system by comparing its costs against potential savings and risk reduction value over a chosen time period. It combines two benefit sources: annual insurance discounts (which accumulate over the years) and the estimated financial value of reduced burglary risk. The net benefit shows whether total savings exceed total costs—system purchase price plus all monitoring fees—or vice versa. The result depends most heavily on the annual insurance discount amount, the system cost, and how you value the risk reduction benefit. For example, a homeowner might use this to compare a one-time system purchase with years of monitoring fees against the cumulative insurance savings and estimated protection value. The calculation assumes the insurance discount remains constant and that the risk reduction value stays fixed annually; actual insurance rates and home circumstances may vary.

Home Security System Economics
Monitored home security combines upfront system cost (400-2,500 depending on complexity) with ongoing monthly monitoring (20-60). Benefits include insurance premium discount (typically 5-20% off homeowner insurance), burglary risk reduction, peace of mind, and potential property value enhancement. The financial case depends heavily on insurance discount magnitude and subjective valuation of risk reduction. Direct savings often do not fully offset monitoring fees; peace of mind value makes up the rest of the decision.
Typical Cost and Benefit Ranges
System cost: 400-800 for basic (sensors, cameras, base station), 800-2,500 for comprehensive. DIY systems (SimpliSafe, Ring Alarm): 300-600 upfront, 20-30 monthly. Professional systems (ADT, Vivint): 600-2,500 upfront, 45-60 monthly. Insurance discount typically 5-15% of homeowner premium, averaging 100-300 annually on typical policies. Burglary risk reduction value subjective — conservative 200-500 annual expected value on contents plus emotional impact. Peace of mind value varies dramatically by household anxiety level.
Worked Example for Standard Installation
System 800. Monthly monitoring 35. Insurance discount 200. Years 10. Risk reduction value 500. Monitoring annual 420. Total system and monitoring over 10 years: 5,000 (800 plus 4,200). Total savings and value: 7,000 (2,000 insurance plus 5,000 risk reduction). Net benefit 2,000. Positive financial case with meaningful risk reduction valuation. At lower risk reduction valuation (200 annual), net becomes -1,000 — net cost but subjective peace of mind value determines whether worth it.
What the Calculator Does Not Model
Specific burglary probability in your area (affects risk reduction value). False alarm fees (some jurisdictions charge 50-200 per false alarm after first few). Equipment upgrades and replacement over long timescales. Contract termination fees for monitored services. Specific insurance policy terms and discount amounts. Home warranty interactions. Regional variations in both system costs and burglary rates. The calculator provides framework; specific household economics vary significantly.
DIY vs Professional Monitoring
DIY options (SimpliSafe, Ring Alarm, Nest) offer 20-30 monthly monitoring versus 45-60 for traditional professional. Annual savings 300-400 for DIY. Professional systems include things DIY lacks: in-home service, professional installation, dedicated monitoring center, smoke/carbon monoxide integration. For standard homes without specialized needs, DIY captures most functionality at substantial savings. Professional worth premium for complex homes, older adults, or peace-of-mind preferences. Calculator works for any system cost and monthly fee configuration.
Home security with $35/mo monitoring totals 2,000.00 over 10 years years.

Sources & Methodology
Methodology
The calculator computes net benefit by modeling costs and savings over a specified time period. Annual monitoring cost is derived by multiplying the monthly fee by 12, then extending across all years. Total cost combines the upfront system purchase with cumulative monitoring expenses. Total savings sum the annual insurance discount and the assigned risk reduction value, both multiplied by the number of years. Net benefit is the difference between total savings and total cost. The model assumes a constant monthly monitoring fee and constant annual insurance discount throughout the period, treats risk reduction as a steady annual value, and does not account for system degradation, fee changes, tax effects, or variations in actual burglary likelihood. Results are estimates based on these input assumptions.
