Instantly calculate the exact lot size, pip value, and risk:reward ratio for any forex pair, gold, or index — based on your account balance and how much you're willing to risk. Used by traders who size every position from a fixed dollar risk instead of guessing.
The exact same math that powers the Kingstone journal — free to use on its own, no sign-up required.
Position size is calculated by dividing your intended dollar risk by the distance between your entry price and stop-loss, converted into pips, then divided by the pip value for that pair. This calculator does that math for you automatically — just enter your account balance, max risk, entry, and stop-loss.
Pip value is how much one pip of price movement is worth in dollars for a given position size. It varies by pair and lot size, which is why a fixed lot size doesn't give you a fixed dollar risk — you need to calculate it per trade.
A 1:2 ratio or better is commonly used, meaning your potential reward is at least twice your risk. This means you can be wrong more often than you're right and still be profitable over time. Use the Risk:Reward tab above to check any trade before entering it.
