FOREX TOOLS
Forex Calculators for Risk, Position Size and Trade Planning
Use these practical calculators before placing a trade. They estimate position size, pip value, margin, risk-to-reward and the return needed to recover from a drawdown.
RISK CONTROL
Position Size Calculator
Calculates the maximum trade size from your account risk and stop-loss distance.
Formula and use
Risk amount = balance × risk %. Standard lots = risk amount ÷ (stop pips × pip value per standard lot). Enter the pip value in your account currency; use the pip calculator below when the quote currency differs.
PRICE MOVEMENT
Pip Value Calculator
Estimates how much one pip is worth for your selected lot size.
Formula and use
Pip value = lots × contract size × pip size × conversion rate. Use the live conversion rate from the pair’s quote currency to your account currency.
CAPITAL REQUIREMENT
Required Margin Calculator
Estimates the account equity reserved to open a leveraged forex position.
Formula and use
Required margin = lots × contract size × base-to-account rate ÷ leverage. A broker may apply different rates by instrument, client type or regulatory entity.
TRADE PLAN
Risk-to-Reward Calculator
Checks the distance to your stop and target before you enter a trade.
Formula and use
Risk/reward = target distance ÷ stop distance. For a buy, the stop must be below entry and the target above it; the relationships are reversed for a sell.
ACCOUNT RECOVERY
Drawdown Recovery Calculator
Shows why limiting losses matters: the percentage gain needed to recover is always greater than the percentage lost.
Formula and use
Required recovery = drawdown ÷ (100 − drawdown). The optional period estimate assumes the same positive return compounds each period and does not include further losses or costs.
Important assumptions
- A standard forex lot is commonly 100,000 units, but contract specifications can differ.
- One pip is commonly 0.0001; many JPY pairs use 0.01. Check the instrument specification.
- These estimates exclude spread, commission, swaps, slippage, minimum lot increments and broker-specific margin buffers.
- Keep a written risk limit and consider the total exposure of correlated positions.
