Crypto profit calculator
A crypto profit calculator is only useful if it includes costs. This one deducts the trading fee when you buy and again when you sell, then compares the proceeds with the amount you started with. Enter the amount invested, the buy and sell prices and the fee percentage; everything runs on your device.
The crypto profit calculator formula
Proceeds = coins × sell price × (1 − fee)
Profit or loss = proceeds − invested
Return = profit or loss ÷ invested × 100
Worked examples
These figures are illustrative. You invest $2,000 in ETH at $3,200 with a 0.2% fee on each side.
| Sell at $2,900 | Sell at $3,600 | |
|---|---|---|
| Coins bought | 2,000 × 0.998 ÷ 3,200 = 0.62375 | 0.62375 |
| Proceeds | 0.62375 × 2,900 × 0.998 = $1,805.26 | 0.62375 × 3,600 × 0.998 = $2,241.01 |
| Profit or loss | −$194.74 | +$241.01 |
| Return | −9.74% | +12.05% |
The price moved 9.375% down in the first case and 12.5% up in the second. The results are slightly worse than those price moves because both fees were paid.
Your break-even price
With a $3,200 buy and 0.2% on each side, break-even is about $3,212.84. Any sale below that price loses money even though the chart shows a small rise.
How to read the result
The figure is a before-tax estimate for a spot purchase. It leaves out network withdrawal fees, spreads hidden in a quoted price and any tax due where you live. It also assumes one buy and one sell; averaging in over several purchases needs each buy entered separately.

Short answers
Does the calculator include tax?
No. Tax treatment depends on where you live and your circumstances. The result is a before-tax figure.
Why is my return lower than the price change?
Because the fee is charged twice, once on the purchase and once on the sale. Each fee reduces the amount working for you.
