Crypto ROI Calculator
A Single Number for Any Coin, Any Holding Period
Return on investment strips a crypto position down to the one figure that actually matters: how much the money grew relative to what went in. It doesn't care whether the asset was Bitcoin, an altcoin, or a basket of tokens, and it doesn't require tracking individual trade fees the way a profit calculator does — just the amount put in and the amount it's worth now. Add a holding period and the same inputs also produce an annualized rate, which is the only fair way to compare a position held six months against one held three years.
The Formula
Annualized ROI = ((Current Value ÷ Initial Investment)365÷Days − 1) × 100
The plain ROI figure treats the whole holding period as one block; the annualized version rescales it to a one-year-equivalent rate so positions of different ages can be compared on equal footing.
A Worked Example
An investment of $5,000 that grows to $8,000 over 274 days:
| Step | Calculation | Result |
|---|---|---|
| Profit | $8,000 − $5,000 | $3,000 |
| ROI | $3,000 ÷ $5,000 × 100 | 60.00% |
| Value ratio | $8,000 ÷ $5,000 | 1.60 |
| Annualized ROI | (1.60365÷274 − 1) × 100 | 87.03% |
The annualized figure is higher than the plain ROI here because the 60% gain happened in under a year — at that pace, a full year would compound to a larger return.
Where This Calculation Matters
- Comparing positions — a 40% gain in three months and a 40% gain in two years are very different outcomes; annualizing puts them on the same scale.
- Portfolio review — a quick sanity check on how a specific holding has performed since purchase, independent of exchange or fee details.
- Setting expectations — extrapolating a short-term rate to see what it would imply over a full year, useful for judging whether a run is sustainable.
How to Use This Calculator
- Enter the initial investment amount in dollars.
- Enter the current value of the holding in dollars.
- Optionally enter the holding period in days to also get an annualized rate.
- Select Calculate to see the ROI percentage, dollar profit, and (if a holding period was given) the annualized ROI.
