Crypto Compound Interest and Annualized Return Calculator
Part 1 compounds a return per period. Part 2 turns a start value, an end value and the days in between into a yearly rate. Arithmetic only; runs in your browser.

Formula
Final amount = start × (1 + r)ⁿ (r = return per period, n = periods)
Annualized return = (end ÷ start)^(365 ÷ days) − 1
Compounding assumes every gain is reinvested and the same rate repeats each period, which real trading results rarely do. A loss in one period cuts the base that later gains compound on.
Examples: 1,000 compounded
| Rate and periods | Final amount | Total return |
|---|---|---|
| 1% a day for 30 days | 1,347.85 | +34.8% |
| 1% a day for 365 days | 37,783.43 | +3,678.3% |
| 5% a month for 12 months | 1,795.86 | +79.6% |
| 0.5% a week for 52 weeks | 1,296.09 | +29.6% |
Frequently asked questions
How do I calculate compound interest on crypto?
Final amount = start × (1 + rate per period) to the power of the number of periods. 1,000 at 1% a day for 30 days becomes about 1,347.85.
How do I calculate an annualized return?
Divide the end value by the start value, raise it to 365 ÷ days held and subtract 1. Going from 1,000 to 1,500 in 180 days is about 127.6% a year.
Why is a high daily return misleading?
Compounding assumes the rate repeats every period and gains are never lost. One large loss resets the base, so a steady daily rate over months is very unlikely in leveraged trading.
