Are these trading calculators really free?
Yes, all calculators are 100% free with no signup required. They run entirely in your browser, so your data stays on your device.
Do these calculators work for forex and futures?
Yes. We have dedicated forex tools (pip value calculator, lot size calculator) and a futures profit calculator with preset contract specs for ES, NQ, CL, GC, and more. The position size and P&L calculators also work across all markets.
How do I calculate my position size?
Divide your dollar risk (account size multiplied by risk percentage) by the per-share risk (the difference between your entry price and stop loss). For example, a $50,000 account risking 1% with a $2 stop equals 250 shares ($500 / $2).
What risk/reward ratio should I aim for?
Most professional traders aim for at least a 2:1 risk/reward ratio, meaning the potential profit is at least twice the potential loss. A 3:1 ratio is considered strong. Use our risk/reward calculator to check your ratio before entering any trade.
