Private, client-side tools to plan trades and understand returns — no signup, nothing leaves your device
These free calculators help you think through a trade before you make it: how much profit or loss you might see, how big a position to take for your risk tolerance, how dollar-cost averaging adds up, and what staking rewards could compound to. Every calculation runs entirely in your browser, so nothing you type is saved, tracked, or sent anywhere.
Numbers are only half the job. Once you have a plan, you can practice executing it risk-free in CustomCrypto's paper trading simulator — real market prices, 38 cryptocurrencies, no account and no real money required.
