Over-leveraging is the #1 way traders blow funded accounts. FundedKit's risk calculator knows your firm's rules, respects your drawdown limits, and gives you the exact position size for every trade — so you never risk more than you should.
A great strategy means nothing if one oversized position wipes out your account. Position sizing is not optional — it is survival.
The #1 reason traders fail challenges is sizing positions too large. One bad trade wipes out days of careful gains, and you are back to square one — or worse, breached.
Without a calculator, traders eyeball position sizes. Some trades risk 0.5%, others accidentally risk 3%. This inconsistency makes your equity curve a rollercoaster and your drawdown unpredictable.
Different firms have different daily loss limits, drawdown types, and calculation methods. Using a generic calculator that does not account for your firm's specific rules is a recipe for accidental rule violation.
FundedKit knows the exact rules for every prop firm you trade with. Enter your account and the calculator automatically pulls your max daily loss, max drawdown, and current usage — then sizes your position to stay safely within limits. No more guessing whether a trade could breach your account.
Whether you trade Forex lots, futures contracts, indices, or crypto — the calculator handles it all. Different pip values, tick sizes, point values, and contract multipliers are computed automatically so you always get the exact position size for your instrument.
Save your preferred risk percentage for each account and switch instantly. Use 0.5% for funded accounts where capital preservation matters most, 1% for challenges where you need to hit profit targets, and 2% for personal accounts where you have more room. One tap to apply the right risk to the right account.
As your drawdown deepens, the calculator automatically reduces your maximum allowable position size. If you have used 60% of your daily loss limit, the calculator will not let you size a position that could breach the remaining 40%. This dynamic protection is the difference between surviving a losing streak and blowing your account.
Three inputs, one answer. The calculator does the math so you can focus on finding great setups.
