Position Size Calculator
Work out which lot size or number of contracts fits your risk per trade.
The position size calculator answers which lot size fits your risk. It is based on account size, risk percentage, stop distance and the value per pip or tick that your broker states.
Calculate Position Size
The grey numbers in the fields are only examples, not a recommendation. Enter your own values.
Fill in all fields and the calculation will appear.
This is a calculation with your inputs, not a recommendation and not investment advice. Price gaps, slippage and fees can increase the loss beyond the calculated amount. You can find the pip or tick value and the step size with your broker.
Why Your Lot Size Should Fit Your Risk
No More Guessing
No arbitrary lot sizes: the size follows your risk.
Forex and Futures
You enter the stop distance and the value per pip or tick yourself. That way the calculation can be used for currency pairs, indices and futures.
Avoid Oversized Positions
Oversized positions are among the typical mistakes. Before the trade, the calculator shows you the risk that a size means.
Risk Management Before the Trade
Setting the position size before the trade is a fixed part of risk management. This calculator makes it quick.
