Why this matters
Position sizing is the part risk-of-ruin is made of
Most blown accounts are not the result of one wrong trade — they're the result of position sizes that were too large for the account, repeated across a losing streak. Deciding your risk percentage before you open a trade, then sizing the position to fit it, keeps any single loss small enough that a losing streak stays survivable.
Set your stop-loss from the chart
The stop distance should come from market structure, not from how big a position you want.
Let the position size follow
The calculator finds the size that makes your risk % and stop distance both true at once.
Common questions
Position size calculator FAQ
What counts as a pip, and why does EUR/USD equal $10 per lot?
For pairs quoted as XXX/USD (EUR/USD, GBP/USD, AUD/USD, NZD/USD), a pip is 0.0001 of price, and one standard lot is 100,000 units of the base currency — so one pip of movement is worth exactly $10 regardless of the current exchange rate. Pairs where USD is the base currency (USD/JPY, USD/CAD) or cross pairs have a pip value that moves with the exchange rate, so use your broker's exact figure for those.
How much should I risk per trade?
There's no universal number, and this tool doesn't recommend one. Many beginners start around 0.5–1% per trade so a losing streak doesn't threaten the account. Your own risk tolerance, strategy win rate and account goals all matter more than any single rule of thumb.
Does this account for spread, commission or slippage?
No — it calculates the theoretical position size from your risk amount and stop distance only. Spread and commission make your real risk slightly higher than the calculated number, so leave some margin, especially on tighter stop-losses.
