SimpliSafe is usually cheapest long-term because you can self-install, avoid a required monitoring contract, and cancel paid monitoring without financing penalties. Confirm with a 60-month comparison: equipment, installation, monitoring, financing interest, and cancellation fees. ADT or Vivint may cost less only when a current written quote changes that total.<\/p>\n

Which system is cheapest over 5 years?<\/h2>\n

SimpliSafe usually has the lowest 5-year ownership cost, especially if you install it yourself or use monitoring only when you need it.<\/p>\n

The catch is that advertised starter prices rarely answer this question. A low equipment promotion can sit beside installation charges, a longer monitoring commitment, or financed hardware. Compare the same number of sensors and the same service period rather than comparing homepage prices.<\/p>\n

Start by choosing a comparison horizon that matches how long you expect to keep the system. Five years exposes recurring costs without assuming you will remain indefinitely. If a move is likely sooner, run a second total for that date and include any early-exit payment.<\/p>\n

\n \ud83d\udca1 Research note:<\/strong> This comparison uses provider terms and published plan information rather than a Domoviq installation test. Ask each company for a dated, itemized quote because promotions and regional terms change.\n <\/div>\n

Our smart home security sensor coverage can help you decide how many entry, motion, glass-break, and environmental sensors your home actually needs. Matching the hardware first prevents a misleading price comparison.<\/p>\n

Sketch each exterior door, accessible window, main hallway, and high-risk room before counting devices. For example, 2 identical homes may need different packages if one has a detached garage or more ground-floor windows. Exclude appealing add-ons unless all 3 quotes include them.<\/p>\n<\/section>\n

How do SimpliSafe, ADT, and Vivint compare?<\/h2>\n

The 3 brands use different purchasing models, so the cheapest choice depends on whether you value flexibility or bundled professional service.<\/p>\n

Flexibility can be valuable even when it does not appear as a line item. A system you can reinstall, expand gradually, or monitor intermittently may reduce future spending. Professional service can instead save setup time and provide one point of contact for troubleshooting.<\/p>\n\n\n\n\n\n\n\n

How should you calculate the real cost?<\/h2>\n

Add every required payment across one realistic ownership period, including costs due when you move or cancel.<\/p>\n

Use a spreadsheet with one row per charge and separate columns for due-now, monthly, and conditional costs. Save the quote and agreement beside it. This makes omissions easier to spot and prevents a salesperson’s bundled monthly figure from hiding hardware debt.<\/p>\n

    \n
  1. List the same devices for each quote, including the base station, keypad, cameras, sensors, smoke detection, and any smart lock.<\/li>\n
  2. Add equipment charges and financing interest. Treat a financed device as a purchase rather than part of the monthly monitoring price.<\/li>\n
  3. Add installation, activation, shipping, permits, and required service visits shown in the written quote.<\/li>\n
  4. Multiply the monitoring payment by 60 for a 5-year comparison, then include scheduled price changes disclosed in the agreement.<\/li>\n
  5. Add likely cancellation, removal, or moving costs. Subtract only discounts guaranteed in writing.<\/li>\n<\/ol>\n

    The formula is: 5-year cost = equipment + financing interest + installation + 60 months of monitoring + other required fees \u2212 guaranteed discounts.<\/strong><\/p>\n

    For example, suppose one fictional quote is $400 upfront plus $30 per month. Its 5-year total is $2,200. Another is $200 upfront, $150 for installation, and $50 per month. That total is $3,350 before financing or cancellation charges. Use your actual quotes, not these illustrative figures.<\/p>\n

    Recalculate whenever a promotion expires or the provider revises a monthly charge.<\/p>\n<\/section>\n

    \n

    Where can the contract change the winner?<\/h2>\n

    A service agreement can outweigh an equipment discount if you move, cancel, or replace the system early.<\/p>\n

    SimpliSafe\u2019s flexible monitoring model reduces that risk. ADT\u2019s agreement length and early-termination terms can vary by package and jurisdiction. Vivint\u2019s service obligation and equipment financing are separate items that may have different payoff rules. Read both documents before signing.<\/p>\n
