Home Security Cost Calculator 2026

Monthly home security costs range from $10/month (Ring self-monitoring) to $60/month (ADT professional full-service). The average American homeowner pays $30–$45/month for professional monitoring. DIY systems cost $15–$25/month for the same level of 24/7 professional monitoring dispatch.

SimpliSafe offers equivalent 24/7 professional monitoring for $18–$28/month vs. ADT's $28–$60/month. SimpliSafe requires no long-term contract; ADT requires 3-year contracts with early termination fees of $800–$1,500. For most homeowners, SimpliSafe offers equal protection at half the cost.

Yes — studies show homes with visible security systems are 300% less likely to be burglarized. A University of North Carolina study found 60% of convicted burglars said alarm systems influenced their target choice. Even visible cameras and alarm yard signs have deterrent effect without active monitoring.

Top home security systems by use case: Best overall value: SimpliSafe ($18–$28/month, no contract, easy DIY install). Best professional installation: ADT ($28–$60/month, 140+ year track record). Best cameras: Ring Alarm Pro ($10–$20/month, integrates with Ring cameras and Alexa). Best no-subscription: Eufy Security ($0/month, local storage). Best for renters: SimpliSafe or Ring (easy to move). All professional systems include 24/7 dispatch, fire/CO monitoring, and cellular backup.

Yes — most major insurance carriers offer a 5–15% discount on homeowners insurance for professionally monitored security systems. Average savings: $80–$300/year on a $1,500–$2,000/year policy. The discount often exceeds the monitoring cost on basic systems. Ask your insurer for their specific security discount requirements — some require UL-listed central monitoring stations.

A basic effective system includes: (1) Door/window sensors on all entry points ($15–$30 each). (2) Motion sensors covering main living areas ($20–$40 each). (3) A central hub/panel that communicates with monitoring center ($50–$200). (4) At least one outdoor camera at the front door ($100–$250). Optional but valuable: glass break sensors, smart locks (allow remote access), video doorbell, and interior cameras. A typical 4-bedroom home needs: 2 motion sensors, 6–8 door/window sensors, 2 outdoor cameras = $400–$800 in equipment.

Upfront installation costs by system type: DIY self-install (SimpliSafe, Ring Alarm): $200–$700 for equipment, $0 installation labor — takes 1–3 hours. Professional installation (ADT, Brinks, Vivint): $99–$299 for equipment + $0–$199 installation (often waived with monitoring contract). Smart home integration (Z-Wave, Zigbee hub-based): $300–$1,000+ for equipment. Video doorbell only (Ring, Nest, Arlo): $100–$300 for doorbell, $0 installation (DIY). Hidden/hardwired cameras (in-wall): $150–$500 per camera installed by electrician. Total for a well-protected 3-bedroom home with 6 door sensors, 2 motion sensors, 2 outdoor cameras, video doorbell, and monitoring: $500–$900 DIY or $300–$500 upfront with a professional monitoring contract. Most monitoring contracts subsidize the hardware cost.

No-contract systems (SimpliSafe, Ring, Abode, Scout) are almost always the better choice for most homeowners. Advantages: no early termination fees ($800–$1,500 with ADT/Vivint), move your equipment to a new home without issues, cancel anytime if your needs change, often lower monthly costs ($15–$25/month vs. $35–$60/month for contract services). When contract systems make sense: Vivint and ADT offer cellular backup, professional installation, and 24/7 dedicated response — their monitoring infrastructure is stronger for high-end systems. But for typical suburban homeowners, SimpliSafe at $18–$28/month provides equivalent protection with no lock-in. Rule of thumb: if you're not committed to staying 3+ years in your home, avoid the contract.

Insurance discounts vary by carrier, but features that consistently earn the largest discounts: (1) UL-Listed central station monitoring — insurers require monitoring from an Underwriters Laboratories-certified station for the maximum 10–15% discount. (2) Smoke + fire + CO monitoring — fire detection often earns larger discounts than burglary monitoring, since fire claims are more expensive. (3) Water/leak sensors — increasingly eligible for discounts as water damage claims rise. (4) Deadbolt locks + security cameras (visible deterrents). Typical cumulative discount: Burglary monitoring alone saves 2–5%. Add fire/smoke monitoring: 5–10% total. Add water/CO: 8–15% total. A 12% discount on a $2,400/year homeowners policy saves $288/year — enough to offset an entire month of monitoring fees. Call your insurer before installing to confirm which certifications and systems qualify for their specific discount program.

Cellular monitoring uses a built-in SIM card (like a cell phone) to communicate with the monitoring center — it works even if your internet or power goes out. Wi-Fi monitoring sends alerts via your home internet connection — if Wi-Fi is cut or goes down, monitoring fails. Cellular backup is the gold standard for true security: an intruder cannot disable your system by cutting your cable line or disabling your router. Systems with cellular backup: SimpliSafe ($180–$500 equipment), Ring Alarm Pro ($249+), ADT (cellular standard on all plans). Cost: cellular monitoring adds $5–$10/month vs. Wi-Fi-only plans. For maximum reliability, choose a system with cellular backup as primary communication, not an optional add-on. Dual-path systems (cellular + Wi-Fi with automatic failover) are the most reliable and recommended for YMYL protection of your family.
