How to calculate crypto profit
Crypto profit is the difference between your exit value and entry value after all trading costs. This page uses one shared formula layer across quick trade, DCA, multi-trade and compare mode.
Core formula
Proceeds = Exit price × Coins sold
Gross profit (long) = (Exit - Entry) × Coins sold × Leverage
Gross profit (short) = (Entry - Exit) × Coins sold × Leverage
Net profit = Gross profit - Total fees
ROI = Net profit ÷ Capital × 100
Worked examples
Spot
Buy 0.50 BTC at €45,000 and sell at €47,000. Gross profit is €1,000 before costs. Net profit depends on trading fees, spread, slippage and network costs.
DCA
Buy €500 at €45,000, then €500 at €42,000, then €500 at €48,000. Weighted average cost shows the blended entry point, which is more useful than any single fill.
Partial Sell
Hold 1.2 BTC with a €43,000 average cost and sell 0.4 BTC at €52,000. Realized profit is calculated only on the sold portion, while the remainder keeps its cost basis.
Leverage
Using €1,000 margin at 5× leverage creates a €5,000 notional position. A small move in price can produce a large ROI on margin, but liquidation risk rises sharply.
Compare
Scenario A may generate the highest net euro gain, while Scenario B may produce a higher ROI. This is why both winner modes matter.
Netherlands Box 3 crypto tax
In Dutch personal tax planning, crypto is usually treated as an asset in Box 3. The tax is based on the value on 1 January and a deemed return framework, not a direct realized trade gain calculation.
Fictitious return = Taxable base × Assumed return rate
Estimated Box 3 tax = Fictitious return × Applicable tax rate
