How it works
Calculates forex or CFD position size based on account balance, risk percentage per trade, and stop-loss distance in pips—helping traders cap loss on any single entry.
Who it's for: Forex and CFD traders applying fixed-percentage risk management rules
Derives recommended lot or unit size from risk dollars and stop distance.
Translates a risk percentage of account equity into a concrete position size.
Updates instantly as you change balance, risk, or pip stop.
How to use
- Enter Account balance in your account currency.
- Set Risk per trade as a percentage of balance (1–2% is common for conservative sizing).
- Enter Stop-loss in pips and Pip value per lot for your instrument and broker.
- Read the recommended Position size before placing the order.
- Adjust if your broker uses micro lots, mini lots, or different pip definitions for JPY pairs.
Good to know
- This is an educational calculator—not financial advice; verify with your broker’s contract specifications.
- Pip value changes with pair, account currency, and lot size—recalculate for each instrument.
- Slippage and gaps can exceed planned risk on volatile news events.
FAQ
- Why does pip value matter?
- The same pip move on different pairs and lot sizes represents different dollar risk—pip value converts pips into money at risk.
