Net profit = (units acquired × sell price − sell fee) − amount invested. Units acquired are calculated by deducting the buy fee from the invested amount before dividing by the buy price.
When should you use this calculator?
This calculator helps you estimate the real return of a cryptocurrency trade, taking into account the fees most exchanges charge on both buying and selling.
Legal context in Spain
Profits from selling cryptocurrency are usually taxed as a capital gain (in Spain, between 19% and 28% depending on the amount), though taxation varies by country of tax residence.
Note that this calculator assumes a single buy and sell operation. If you bought in several trades at different prices, work out your average buy price first before using this tool.
The result is a mathematical estimate and does not constitute tax or investment advice. Cryptocurrencies are highly volatile; only invest what you can afford to lose.
Frequently asked questions
How is the return on a crypto investment calculated?
The invested amount is subtracted from the net sale value (after buy and sell fees), and the result is divided by the invested amount to get the percentage return.
Do I have to pay taxes on crypto gains?
In most countries, yes: gains are treated as capital gains and taxed when you sell or exchange the cryptocurrency. In Spain they are declared between 19% and 28% depending on the amount. Check the rules in your own country.
What if I bought in several separate trades?
Work out your weighted average buy price (total amount invested divided by total units) and enter it as a single buy price in the calculator.
Does this calculator work for any cryptocurrency?
Yes, it works the same way for Bitcoin, Ethereum or any other cryptocurrency, since it only depends on the amounts and prices you enter, not the specific asset.
