Free trading calculators
Five calculators covering the maths that actually decides outcomes: how big a position should be, whether a trade's payoff justifies its hit rate, what a result is worth in R, and what a drawdown really costs to recover.

Free risk/reward ratio calculator. Enter entry, stop and target to get your R:R, plus the win rate you would need to break even at that ratio.
R-Multiple and Expectancy Calculator

Drawdown Recovery Calculator
Work out the gain required to recover from a drawdown. Enter a percentage loss to see the percentage gain needed to get back to break even.
