Free Trading Calculators
Every trade needs a few numbers before you click buy: how big the position should be (in shares or futures contracts), what win rate your reward:risk has to beat, and on a funded account, how much drawdown room you have left. These calculators work them out in your browser. No signup, no chart upload, no AI.

How they fit together
Size it, check the bar, then grade the setup
- 1
Size the trade
Start from your stop. The position size calculators turn your risk into a share count, or a contract count using the real futures point value, so a loss costs what you planned and not a dollar more. On a prop firm account, the drawdown calculator tells you what that risk should be.

Check the win rate you need
Your target and stop set a reward:risk, and that ratio sets the minimum win rate to break even. The breakeven calculator shows that bar and your expectancy at your real win rate.

Grade the setup itself
Neither calculator knows if the chart is any good. That part is a read of structure and confluence, which is what SnapPChart grades from a screenshot, A+ to F, with an entry, stop, and targets.
The math is done. Is the setup worth taking?
Upload a chart screenshot and SnapPChart grades the setup quality in seconds, with the levels you would plug straight into these calculators.
