How the opportunity cost calculator works
Every unused subscription has two costs. The first is obvious: the cash that leaves your account each month. The second is hidden — the opportunity cost, or what that same money could have become if you had invested it instead. List your subscriptions above — monthly or yearly — and this calculator shows both.
We convert every subscription to a monthly figure (yearly plans are divided by 12), add them up, and project that total two ways. The first is a simple sum: your monthly spend multiplied by 12 months and your chosen number of years. The second treats that monthly amount as a recurring investment, compounding at your chosen annual return rate using the standard future value of an annuity formula. The gap between the two is the growth you gave up.
The fix is simple: know what you're paying for and cancel what you don't use. Renew Reminder brings every subscription into one place and reminds you before each renewal, so a free trial or forgotten app never quietly turns into years of wasted money.
