Crypto ROI Calculator
Calculate return on a crypto investment, including the annualised rate.

What the Crypto ROI Calculator does
ROI expresses your gain as a percentage of what you put in. The annualised figure matters in crypto because holding periods vary so widely — a 50% gain over one month is a very different result from the same gain over three years.
Formula
ROI = (Current value − Invested) ÷ Invested × 100Annualised = (Current ÷ Invested)^(365 ÷ Days) − 1

Frequently asked questions
Why does a 50% loss need a 100% gain to recover?
Because the gain is calculated on the smaller remaining balance. Losses and gains are not symmetric, which matters a great deal in a volatile asset class.
