Which is cheapest over 5 years — SimpliSafe, Ring, or ADT?

Ring Pro at $20/mo with month-to-month monitoring is typically the cheapest 5-year total at around $1,400 (equipment + monitoring). SimpliSafe Standard at $29.99/mo lands around $2,090. ADT Complete Pro at $49.99/mo with a 36-month contract lands around $3,120 — and that's before any escalator increases or ETF risk.

Does ADT include better hardware?

ADT's professionally-installed system uses Honeywell-derived equipment with a longer expected life cycle and integrated cellular backup as standard. SimpliSafe and Ring use proprietary hardware with shorter typical refresh cycles but lower upfront cost. For most homes, the hardware quality difference doesn't justify the monthly premium.

Can I switch between these brands later?

Yes, but the equipment doesn't transfer. Each brand uses proprietary panels and sensors. Switching means new hardware. SimpliSafe and Ring (no contract) make switching free. ADT (contract) charges an ETF — see the switching guide for the math.

What about response time differences?

All three offer professional monitoring with central station dispatch. Average response times to verify and dispatch: ADT 30–45 seconds, SimpliSafe 30–60 seconds, Ring Pro 30–60 seconds. Real-world response also depends on your local police/fire response times, which all three providers depend on equally.

SimpliSafe vs Ring vs ADT — Real 5-Year Cost Comparison

TL;DR

Over 5 years for a typical 3-bedroom home, the honest total cost is roughly:

| Brand | Equipment | Monitoring | 5-Yr Total | Worst-case ETF | |---|---|---|---|---| | Ring Pro | ~$200 | $20/mo × 60 = $1,200 | ~$1,400 | $0 (no contract) | | SimpliSafe Standard | ~$290 | $29.99/mo × 60 = $1,800 | ~$2,090 | $0 (no contract) | | ADT Complete Pro | $0 down (financed) | $49.99/mo × 60 = $3,000 | ~$3,000–$4,000 | $1,000–$2,500 mid-contract |

ADT's monitoring quality is real but doesn't usually justify the 2× cost premium vs Ring or SimpliSafe for most homeowners. ADT makes sense when you specifically want pro install + cellular backup as standard + traditional monitoring infrastructure.

How we calculated each total

Equipment baseline: 3-bedroom home — entry sensors on 2 doors and 4 windows, motion sensor in main living area, indoor + outdoor camera, smart hub, smoke/CO detection.

Monitoring tier baseline: Mid-tier with professional dispatch + cellular backup + mobile app.

Time horizon: 60 months. We assumed no major equipment upgrades within the 5 years.

Did NOT include:

Smart-home subscriptions (e.g., advanced AI features)
Camera storage upgrades beyond default
Add-on sensors after the initial kit
Local taxes
Possible rate escalator increases (assumed 0% for clean comparison; real escalators add 2–8% over 5 years)

The brand-by-brand breakdown

Ring Pro — $1,400 / 5 yr

Equipment: $199.99 Ring Alarm Pro 8-piece kit (panel, keypad, 4 contact sensors, motion, range extender). Add 1 doorbell ($199.99) and 1 stick-up cam ($99.99) — $300 in cameras for camera coverage. Total ~$500 for a fully-loaded setup OR $200 for the alarm-only entry path.

Monitoring: Ring Protect Pro at $20/mo. Includes 24/7 professional monitoring, 24/7 video recording (up to 180 days), cellular + battery backup, alarm-system pro monitoring.

Contract: None. Cancel any month with no fee.

Hardware quality: Solid for the price. Cameras have 1080p video, color night vision on newer models, two-way audio. Sensors are reliable; battery life on contact sensors is 2–3 years.

Best for: Cost-conscious buyers who want a comprehensive system without contract exposure.

Trade-offs: Self-install (some find this a plus). Ring's voice-assistant integration is strongest with Alexa.

SimpliSafe Standard — $2,090 / 5 yr

Equipment: SimpliSafe Foundation 5-piece kit at $244.96 OR build a custom kit (~$290 for a 3-bedroom). Cameras are a separate purchase: $169.99 SimpliCam, $169.99 Smart Alarm Wireless Indoor Cam.

Monitoring: Standard Monitoring at $29.99/mo. Includes 24/7 professional monitoring, 60-day money-back guarantee, intrusion + smoke + CO + water + freeze monitoring.

Contract: None. Cancel any month with no fee.

Hardware quality: SimpliSafe sensors are well-regarded — battery life 5+ years on contact sensors. Cameras adequate but not class-leading.

Best for: Buyers who want a "set it and forget it" experience with strong professional monitoring and zero contract exposure.

Trade-offs: Camera ecosystem is weaker than Ring's. Subscription tiers can be confusing — make sure you're on the tier that includes everything you need.

ADT Complete Pro Install — $3,000–$4,000 / 5 yr

Equipment: $0 upfront with the Pro Install bundle. Equipment is leased / included with the monitoring contract — you don't keep it if you cancel.

Monitoring: Complete tier at $49.99/mo. Includes pro install (separate one-time install fee may apply at $99–$199), 24/7 monitoring, mobile app, smart-home features.

Contract: 36-month contract is standard. ETF formula: 75% of remaining monthly payments. Mid-contract cancellation typically costs $675–$1,000.

Hardware quality: Honeywell-derived professional-grade equipment with longer life cycles than DIY brands. Cellular backup is standard.

Best for: Buyers who specifically want professional installation + traditional monitoring infrastructure + the brand recognition that comes with ADT.

Trade-offs: Cost. Roughly 2× the 5-year total of SimpliSafe and Ring. Long contract creates significant ETF exposure if your situation changes.

The hidden math: ETF and rate escalator

The headline numbers above assume zero rate increases and zero early cancellation. Both assumptions are usually wrong:

Rate escalator scenario: ADT's contract typically allows up to 3% annual increase. Year 1 = $49.99/mo, Year 2 = $51.49, Year 3 = $53.03, Year 4 = $54.62, Year 5 = $56.26. Real 5-year monitoring cost: $3,202 (not $3,000). The escalator alone adds $202.

Mid-contract cancellation scenario: If life changes at month 18 of the ADT contract:

Add $675 ETF to ADT's total
ADT 5-year actual = $1,500 (months 1–18 paid) + $675 ETF + ($1,200 SimpliSafe replacement over remaining 42 months) = $3,375
vs SimpliSafe-from-day-one = $2,090

That's a $1,285 penalty for picking ADT and changing your mind.

When ADT actually wins

There are real scenarios where ADT is the right answer despite the cost:

You want a single contractor handling install + monitoring so there's one phone number for support
You're not handy with DIY installation and don't want to mess with sensor pairing, glue mounts, or app setup
Your insurance discount is materially higher with monitored ADT specifically (rare but happens — verify with your insurer)
You want the brand-recognition signage as part of your visible deterrent strategy (some studies suggest yard signs do reduce burglary attempts)
Your home is 4,000+ sq ft with complex sensor needs that benefit from a pro installer's site assessment

For ~70% of buyers, none of those conditions hold and SimpliSafe or Ring is the better total-cost answer.

When Ring wins over SimpliSafe

You want camera coverage as the primary feature. Ring's camera ecosystem is broader and better-priced.
You're already in the Amazon/Alexa ecosystem. Tighter integration.
You want the lowest total cost. Ring monitoring at $20/mo vs SimpliSafe at $29.99/mo saves $600 over 5 years.

When SimpliSafe wins over Ring

You prioritize the alarm system over cameras. SimpliSafe's sensor reliability and battery life is class-leading.
You want a more polished "professional" feel to the user experience.
You want broader environmental monitoring (water, freeze) included by default.
