Crypto ROI Calculator
ROI (Return on Investment) shows in a single percentage how your total crypto investment has performed, regardless of how many different coins, exchanges or purchase moments were involved. Enter what you invested in total and what your portfolio is worth now, and you instantly get your gain or loss in both currency and percentage.

- ￥3,500
How this was calculated
- 1Difference from the investment￥8,500 − ￥5,000 = ￥3,500
- 2Divide by the investment÷ ￥5,000 × 100 = 70%
公式
ROI (%) = (current value − investment) ÷ investment × 100
You subtract your total investment from the current portfolio value; that difference is your gain or loss in currency. Divide that amount by the investment and multiply by 100 to express it as a percentage. An ROI of 100% means your investment has doubled, while an ROI of −50% means half your investment has evaporated.
ステップ解説
- 1Enter the total amount you have put into crypto, across all coins and purchases, in the "Total invested" field.
- 2Enter what your whole portfolio is worth right now, at current prices, in the "Current value" field.
- 3Read your ROI in percent instantly, along with your gain or loss in currency and the calculation’s intermediate steps.
計算例
€ 5,000 invested (example), now worth € 8,500
→ Gain = € 3,500, ROI = +70% ((8,500 − 5,000) ÷ 5,000 × 100).
€ 1,000 invested (example) when an altcoin was still cheap, now worth € 4,000
→ Gain = € 3,000, ROI = +300% — the investment has quadrupled.
€ 10,000 invested (example) at the market peak, now only worth € 6,500
→ Loss = € 3,500, ROI = −35% ((6,500 − 10,000) ÷ 10,000 × 100).
Reference table
| Multiple | ROI | € 1,000 invested becomes |
|---|---|---|
| 1.5x | +50% | € 1,500 |
| 2x | +100% | € 2,000 |
| 3x | +200% | € 3,000 |
| 5x | +400% | € 5,000 |
| 10x | +900% | € 10,000 |
| 20x | +1,900% | € 20,000 |
This shows how a price multiple translates to ROI: doubling your money is +100% ROI, not +200%. These figures are an illustrative example, not a price forecast.
よくある間違い
- Confusing ROI with absolute profit; a high ROI on a small investment can yield less money than a low ROI on a large one.
- Only counting the most recent purchase instead of every deposit, which skews the whole portfolio's ROI too high or too low.
- Forgetting that trading fees, transaction costs and any tax still need to be subtracted from the gain before you know your net return.
活用シーン
- Seeing your whole portfolio's performance at a glance, even when it consists of dozens of coins and purchases.
- Comparing different crypto investments against each other to see which has performed best.
- Deciding whether it's time to take profit by seeing exactly how much percentage return is already on the table.
よくある質問
What is a good crypto ROI?
That depends entirely on your time horizon and risk tolerance; there is no universal benchmark for such a volatile market. An ROI that would be exceptional in stocks can happen in crypto within a single month.
Does ROI include profit I haven't cashed out yet?
Yes, this calculation is based on the current value you enter, so it is an "on paper" ROI as long as you haven't sold. The profit only becomes final after you sell; until then the price can still move.
Can I also use this to calculate the ROI of a single coin?
Absolutely, just enter the investment and current value of that one coin instead of your whole portfolio. The formula stays exactly the same; only the scope of the numbers changes.
Why is my ROI negative even though the price has gone up?
Your average purchase price was probably higher than the current rate, for example because you bought (partly) at a peak. ROI looks at your own investment versus the current value, not the price movement in isolation.
