Bitcoin Calculator
Instantly calculate what your Bitcoin is worth in euros. The price field autofills with the current live rate via CoinGecko, but you can always enter your own price — for example to value a past purchase or model a future scenario.
Ethereum Calculator
Work out what your Ethereum is worth in seconds. The price field autofills with the current ETH rate via CoinGecko, but you can always overwrite that number to run your own scenario — for example using a specific exchange rate or an expected future price.
XRP Calculator
Calculate what your XRP is worth in euros. Because a single XRP typically costs only a fraction of a euro, larger quantities are usually involved than with Bitcoin or Ethereum. Enter the number of XRP and a price — it autofills with a current market rate, but you can enter your own price to run a different scenario.
Crypto Profit Calculator
Want to know how much profit or loss you made on a crypto trade? Enter the buy price, sell price and number of coins for an instant calculation, including the percentage return. Handy for quickly checking how a closed position performed without doing the maths yourself.
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.
Crypto DCA Calculator
Dollar-cost averaging (DCA) means periodically investing a fixed amount, regardless of the price at that moment. Enter your periodic investment, number of periods and average purchase price to see the outcome.
Crypto Staking Calculator
With crypto staking you lock up coins to help secure a proof-of-stake network, and in return you earn a reward, usually quoted as an annual percentage yield (APY). Because most staking platforms and validators credit rewards daily and automatically restake them, your balance grows through compound interest rather than a flat yearly payout. This calculator shows exactly how much your staked amount is worth after any number of days, assuming daily compounding at a fixed APY.
Crypto Mining Calculator
Mining is only profitable as long as the value of the coins you mine outweighs what you burn in electricity. Enter how many coins your hardware produces per day, the current price, its power draw in watts and your price per kWh, and you instantly see your daily profit or loss.
Crypto Fee Calculator
Exchanges and networks charge a fee on almost every crypto transaction, usually as a percentage of the amount. This calculator instantly shows how much you pay in fees and what remains net of your trade amount, so you are never caught by surprise.
Crypto Portfolio Allocation Calculator
Diversification is crucial in crypto investing. This calculator helps you distribute your portfolio across multiple asset classes according to a strategic allocation — particularly effective for limiting risk and optimizing return potential.
The crypto world revolves around numbers: prices, profit, returns, staking and transaction fees. This category offers free calculators that help you understand those numbers and make informed choices.
Calculate your profit or loss, plan a DCA strategy, estimate staking rewards or compare transaction fees — with live prices where possible and clear formulas throughout.
