Free trading calculators for risk-first practice

Calculate account risk, units, position value, and risk/reward before practicing a setup. These tools are educational and designed for paper-trading workflows, not financial advice.

Position size calculator

Enter account size, risk percentage, entry price, and stop price to estimate the number of shares or units that fit the planned account risk.

Risk/reward calculator

Compare distance from entry to stop against distance from entry to target. A setup with a larger possible reward than planned loss is easier to review objectively.

Then practice it

Pick a setup in the game, decide your entry, stop and target before you reveal the next candle, and size the trade with the calculator. After the round, check whether the stop and target you chose were realistic.

Limitations

Real markets include spread, slippage, fees, liquidity, taxes, and emotion. A calculator cannot predict outcomes or remove risk. Use it for learning and practice planning only.
