Subscription Cost Calculator
Add up your monthly subscriptions and see the yearly, 5- and 10-year cost plus what that money could grow to at a return you choose. No bank link.
In short
Add up your monthly subscriptions and see the yearly, 5- and 10-year cost plus what that money could grow to at a return you choose. No bank link.
Formula: Monthly total = sum of subscriptions. Invested value = monthly × ((1 + r)^m − 1) ÷ r, with r = yearly return ÷ 12 and m = months (future value of an ordinary annuity, monthly compounding).
What this calculator does

Formula
Prices are assumed to stay the same; real subscriptions often rise.
Monthly total = sum of subscriptions. Invested value = monthly × ((1 + r)^m − 1) ÷ r, with r = yearly return ÷ 12 and m = months (future value of an ordinary annuity, monthly compounding).
Inputs used: Subscription 1 per month, Subscription 2 per month (blank = none), Subscription 3 per month (blank = none), Subscription 4 per month (blank = none), Subscription 5 per month (blank = none), Subscription 6 per month (blank = none), Subscription 7 per month (blank = none), Subscription 8 per month (blank = none), and other shown inputs.
Worked example
Four subscriptions at 7%
- Monthly = 57.47; yearly = 689.64.
- r = 0.07 ÷ 12; m = 60.
- FV = 57.47 × ((1 + r)^60 − 1) ÷ r ≈ 4,114.90.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Prices and returns are assumed constant.
- Ignores taxes and fees on investments.
- Up to eight subscriptions; combine small ones if you have more.
- An estimate built only from the figures you enter. It is not financial, tax, legal or employment advice, and real costs, taxes and returns vary.
- The result depends on the values you enter for this subscription cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
