No signup, no email, no catch. Six calculators we built because we got tired of estimating these numbers by hand. Run yours before you place a trade.
The "0% fees" claim isn't the real cost. See the true all-in drag — spread, gas, on/off-ramp fees, and the opportunity cost of locked capital — plus the breakeven move you need.
Open calculator →Turn any share price into shares bought, payout, profit, and ROI — and the breakeven win rate you need to be profitable over the long run.
Open calculator →Net P/L on any long or short trade with fees and leverage factored in. Shows quantity, gross P/L, fee drag, ROI on margin, and the liquidation price for leveraged setups.
Open calculator →Simulate a dollar-cost-average plan against any average price and volatility — and see whether DCA actually beats lump-sum in your scenario. Shows effective cost basis and final P/L.
Open calculator →Enter your monthly volume and trade count — the tool ranks Bybit, Bitget, OKX, KuCoin, MEXC, and Kraken by what you'd actually pay, and shows your annual savings.
Open calculator →The 1% rule, done for you. Enter account size, risk tolerance, entry, and stop — get the exact position size, units, and margin so one loss never blows your plan.
Open calculator →Most "free calculator" pages online are thin wrappers stuffed with ads. Ours aren't. Each tool does the math we actually run before our own trades — and each one is free to embed on your own site via a simple iframe snippet on the tool's page. If a number matters to a trade, there should be a calculator for it. More tools are on the way.
