How to Use the Home Security Buy vs Subscribe Calculator
As more people live alone or in newly formed households, interest in home security systems has grown right along with it. The first big decision is usually whether to buy equipment outright and self-monitor, or pay for a monthly subscription plan. This calculator projects the total cost of each option over a chosen period so you can see which one actually saves you money.
Buying outright means a larger upfront cost, but with little to no ongoing monthly fee afterward, so the total cost drops the longer you use it. A subscription plan has a lower barrier to entry but comes with an ongoing monthly charge, and it usually includes 24/7 professional monitoring and emergency dispatch when something is detected — which adds real convenience.
Rather than comparing total cost alone, consider how long you plan to stay in your current home and whether professional monitoring or dispatch service actually matters to you. If you move frequently, like in a rental, the lower upfront cost of a subscription can be more practical, while homeowners planning to stay long-term often come out ahead by buying.
Frequently Asked Questions
If you'll use it for 3 years or more, buying outright usually wins on total cost. But it requires a larger upfront payment, and without professional monitoring or dispatch, the actual security benefit can be lower.
Lower upfront cost, and most plans include 24/7 professional monitoring, emergency dispatch, and free equipment replacement, which means less hassle managing the system yourself.
