Open tool →Why use a crypto calculator?
Crypto math is easy to get wrong in your head. Fees are flat rather than percentage-based, profit isn't the same as your taxable gain, staking APY hides token inflation, and a transfer on the wrong network can be lost for good. A purpose-built calculator removes the guesswork: you enter your own numbers and get an exact figure in seconds, so you can decide before you act rather than after. Each tool here does one job well and shows its working, so you understand the result instead of just trusting it.
Which tool should you use?
Start with the crypto profit calculator to see your exact gain or loss after fees before you sell. Use the staking calculator to estimate rewards and APY on coins you already hold, and the DePIN ROI calculator to find a device's real break-even. Before moving funds, the cheapest-way-to-send tool picks the lowest-fee safe network and Send Crypto Check walks the pre-send checklist; if something already went wrong, the Wrong-Network Checker explains your options.
Are these tools free and private?
Yes. Every calculator is free, needs no account, and runs entirely in your browser — your inputs never leave your device and nothing is stored on our servers. We also never ask for your seed phrase, private keys, passwords, or 2FA codes, and no legitimate tool ever will.
Never enter seed phrases, private keys, wallet passwords, 2FA codes, or API secrets into any tool here. Our tools never need them.
