Forex Position Size Calculator — Lots Per Risk
Calculate exact forex position size in units, standard lots, mini lots, and micro lots based on your account currency, pair and stop-loss in pips.
At risk: 100.00 USD if the stop hits.
Why forex position sizing has an extra step
Stock sizing is simple: risk in $ ÷ risk per share = number of shares. Forex adds a wrinkle: your pip value depends on the pair and your account currency. A pip on EUR/USD is worth more to a USD account than a pip on AUD/JPY (different quote currency, different cross-rate). This calculator does all the conversion for you.
The math behind it
Risk amount = account × risk %. Pip value per unit = pip-size × quote-currency-to-account-currency rate. Position size = risk amount ÷ (stop in pips × pip value per unit). The answer is in units (1 standard lot = 100,000 units), and the tool shows the equivalent in lots so you can plug it into your platform.
Starting out
If you're learning, use micro lots (1,000 units). Same skill set as standard lots, 1% the risk. Once you can execute consistently for 6 months you can scale up. Anyone telling you to start trading standard lots with a small account is selling you something.
