Subscription Cost Calculator
A small monthly subscription feels harmless, but stretched over years — and nudged up by regular price rises — the total can be startling. This calculator adds up everything you will pay for a subscription across its lifetime, including compounding annual increases. It works in any currency.
- First-year cost
- Remaining years
- Monthly cost
- $15.00
- Yearly cost
- $180.00
- Years
- 5
- Total over period
- $900.00
That 15-a-month subscription adds up to 900 over 5 years. Invested instead at a typical return, the same money could have grown well beyond what you paid.
How it works
A subscription is a recurring drip rather than a single purchase, which is exactly why it slips past most budgets. Twelve monthly payments make up a year’s cost, and the calculator sums those yearly costs across the period you expect to keep the service.
The twist is the annual price rise. Streaming services, software, and gym memberships rarely hold their price for long. If a service raises its fee a few percent each year, those increases compound — year three costs more than year two, which already cost more than year one. A flat estimate of "monthly price times months" misses this and understates the real total. The calculator applies each year’s increase on top of the last, so the figure reflects what you will actually hand over.
The deeper cost is opportunity cost: money spent on a subscription is money not invested. A modest monthly sum, invested at a typical long-run return instead, could grow to considerably more than the total you paid. That does not mean every subscription is a mistake — only that the true price is the spending plus the growth you gave up. Use the currency switcher to view the totals in your own currency.
Total = Σ over each year y (from 0 to years−1) of monthly cost × 12 × (1 + annual increase%/100)^y. Yearly cost = monthly cost × 12.
Worked example
Take a 15-a-month service kept for 5 years with no price rises. Each year costs 15 × 12 = 180, and five years add up to 900. Now add a 10% annual price rise: year one is still 180, but year two is 198, year three about 218, and so on, pushing the five-year total to roughly 1,099 — almost 200 more than the flat estimate, purely from compounding increases.
Things to watch out for
The calculator rounds the term to whole years, so part-years are not counted. It assumes the price rise compounds annually from the start; a service that holds its price for a while will cost a little less. Annual or multi-year billing is often cheaper per month than rolling monthly — convert any such plan to an effective monthly figure before entering it here. Bundles that replace several separate subscriptions can change the picture entirely.
Frequently asked questions
Why include an annual price rise?+
Because most subscriptions raise their price over time, and those rises compound. Ignoring them understates the lifetime total, sometimes substantially over five or ten years.
What is the opportunity cost of a subscription?+
It is the growth you forgo by spending rather than investing. The same monthly amount invested at a typical return could grow to more than the total you pay — the real cost is the spending plus that lost growth.
Should I always cancel subscriptions?+
No. The point is to see the true lifetime price so you can judge whether the value matches it. Some subscriptions are well worth their compounded cost; the calculator just makes that cost visible.
Can I use this for any currency?+
Yes. The total is a straight sum of payments, so it works in any currency. Use the switcher at the top to display the figures in yours.
