About Crypto tools
Calculators for the sums behind every crypto trade. Work out the profit and ROI of a trade after fees, your average price over many buys and how much it takes to average down, where a leveraged long or short gets liquidated, how big a position to take for the risk you choose, and what staking earns with APY or APR. Convert wei, gwei and ether, or sats and bitcoin, exactly. You type the prices, so nothing is fetched and nothing you enter leaves your device.
Frequently asked questions
Are these crypto calculators free?
Yes, completely free with no sign-up, no limits and no exchange account needed.
Do they use live prices?
No. You enter the prices yourself, so you can test any scenario. Nothing is fetched or sent, and they work offline once the page has loaded.
Do they work for any coin?
Yes. Bitcoin, Ethereum, Solana or any altcoin, priced in any currency. The maths is the same for every coin.
Is this financial advice?
No. These are calculators. Crypto prices move fast and leveraged trading can lose your whole margin; decide for yourself and only risk what you can afford to lose.
