Free Forex Calculators
These browser-based forex tools are designed to make common trading calculations transparent. Use them to estimate position size from a defined risk budget, calculate pip value, estimate required margin, model profit or loss, understand drawdown recovery, test a simplified risk-of-ruin scenario, and project managed-account growth.
Each calculator shows the assumptions behind the result. The outputs are educational estimates, not investment advice or a prediction of future performance.
Estimate a position size from account balance, risk percentage, stop-loss distance and the pip value of one standard lot.
Formula: risk amount = balance × risk%; lot size = risk amount ÷ (stop pips × pip value per standard lot).
Calculate the value of one pip in the quote currency for a standard forex contract size of 100,000 units.
Formula: pip value in quote currency = 100,000 × lots × pip size. If your account currency differs from the quote currency, conversion is still required.
Estimate the margin required to open a leveraged forex position when your account currency matches the pair's quote currency.
Formula: notional value in quote currency = lots × 100,000 × market price; required margin = notional value ÷ leverage.
Estimate profit or loss in the quote currency from entry price, exit price, direction and position size.
Formula: P/L = signed price move × 100,000 × lots. The result is in the pair's quote currency and excludes spread, commission, swap and slippage.
Measure the percentage drawdown from a prior equity peak and the gain required to recover to that peak.
Formula: drawdown = (peak − current) ÷ peak; recovery required = (peak − current) ÷ current. A 50% loss requires a 100% gain to recover.
Estimate how often a simplified fixed-fraction strategy crosses a chosen drawdown threshold over a defined number of trades.
Method: 3,000 deterministic Monte Carlo paths with independent binary wins/losses and fixed-fractional risk. This is a model, not a forecast; real returns, correlations, gaps and variable trade outcomes can materially change risk.
Projection Tool
Model a hypothetical monthly return and a simplified performance fee charged only on positive monthly gains. This does not model high-water marks, hurdle rates, deposits, withdrawals, taxes or broker charges.

Fxtriangle keeps the core calculations visible so you can understand what each output represents rather than treating the result as a black box.
Forex and leveraged products involve substantial risk. Calculator outputs are estimates for education and planning only. They do not guarantee performance or determine whether a trade is suitable for you.
