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.

Frequently asked questions

How much money am I really wasting on unused subscriptions?

Most people lose $200–$300 a year to subscriptions they've forgotten about or barely use. But the real cost is bigger: if that same money were invested instead of spent, it would compound over time — often into thousands of dollars over a decade, as the calculator above shows.

What is the opportunity cost of a subscription?

Opportunity cost is what your money could have earned somewhere else. A $15/month subscription isn't just $180 a year — invested at a historical average market return, that money could grow into far more over time. The difference between what you spent and what it could have become is the opportunity cost.

What return rate should I use in the calculator?

We default to 10%, the long-term historical nominal average of the S&P 500. You can also pick Bonds (~5%), REITs (~11%), or Tech stocks (~14%), or drag the slider to any rate. These are historical averages, not guarantees of future returns.

Do you handle yearly subscriptions too?

Yes. Each subscription can be set to monthly or yearly billing, and the calculator converts everything to a monthly figure (yearly plans are divided by 12) before running the math — so annual plans are counted accurately.

How do I stop wasting money on subscriptions?

Track them all in one place and cancel what you don't use. Renew Reminder brings every subscription — monthly and yearly, across all your cards — into one dashboard and reminds you before each renewal, so a free trial or forgotten app never quietly turns into years of wasted money.
