Risk Management

Calculator
Lot Size & Position Size Calculator

Find the lot size that risks exactly the amount you choose, from your balance, risk per trade and stop-loss distance.

Stop Loss Calculator

Find where to place your stop loss so a losing trade costs exactly what you planned, or see the stop price and the amount at risk for a stop in pips.

Risk-Reward Ratio Calculator

Get the risk-reward ratio of a trade and the win rate you need to break even at that ratio.

Risk of Ruin Calculator

Estimate the probability that a strategy reaches a chosen drawdown, from its win rate, reward-to-risk ratio and risk per trade.

Kelly Criterion Calculator

Calculate the Kelly fraction from your win rate and average win/loss ratio, with half and quarter Kelly alongside.

Drawdown Calculator

Find the gain needed to recover from a drawdown. A 50% loss needs a 100% gain to get back to even.

Margin Call & Stop-Out Calculator

See your margin level and how much loss your account can take before a margin call or stop-out.

Position & Value

Calculator
Pip Calculator

See what one pip or point is worth for any position size, converted into your account currency.

Margin Calculator

Work out how much margin a position ties up at your leverage, and the position value behind it.

Leverage Calculator

Work out the real leverage of a trade — position value divided by your equity — the margin it ties up, and the largest position your account leverage allows.

Convert an amount between currencies at a reference rate, or at your own bank's or broker's rate.

Profit & Cost Analysis

Calculator
Profit Calculator

Break-Even Price Calculator

Find the price a trade has to reach to cover its spread and commission.

Stock & Crypto Average Price Calculator

Work out the average price of a position bought (or sold short) in several parts, what it is worth at today's price, and how much more you would need to buy to bring the average down to a target.

Spread Cost Calculator

Turn the spread into money per trade, per month and per year.

Swap Calculator

Work out the overnight swap you pay or earn on a position, including triple-swap nights.

Commission Calculator

Work out what broker commission costs per trade, per month and in pips, whether it is quoted per lot, per million notional (cTrader) or as a percentage of the position value.

Take Profit Calculator

Find how many pips you need, and the take-profit price, to make a set amount on your position.

Performance

Calculator
Trading Expectancy Calculator

Find out what a trading strategy makes or loses per trade on average, from its win rate and average win and loss, with the profit factor, win/loss ratio and the win rate it needs to break even.

Sharpe Ratio Calculator

Measure return per unit of risk: the Sharpe ratio from an average return and standard deviation or from a list of period returns, annualised, with the Sortino ratio for downside risk.

Technical Tools

Calculator
ATR Position Size Calculator

Set your stop from the Average True Range and size the position so it risks a fixed share of your balance.

Pivot Point Calculator

Calculate pivot points and support and resistance levels from the previous period's high, low and close.

Crypto Futures & Liquidation Price Calculator

Profit and ROI, the price that hits a target return, and the estimated liquidation price for a USDT-margined perpetual such as BTCUSDT, at any leverage, for isolated or cross margin.

Prop Firm

Calculator
Prop Firm Drawdown Calculator

See how much you can still lose today and in total before you breach your prop firm's daily or maximum loss limit, static or trailing — and the biggest position your next stop loss allows.

Consistency Rule Calculator for Prop Firms

Check whether your best day is within your prop firm's consistency rule, how much more profit you need if it is not, and how much you can make tomorrow without breaking it.

Why use forex calculators?

Trading forex without proper calculations is like flying blind. You might get lucky a few times, but eventually the math catches up. These calculators help you trade with precision instead of guesswork.

Position sizing is where most traders fail. Risk 2% of your account on one trade and 5% on the next, and your results become random. Our position size calculator standardizes your risk so every trade has the same impact on your account.

Understanding pip values across different pairs and lot sizes prevents costly surprises. A pip on EUR/USD is worth something different than a pip on GBP/JPY. Our pip calculator handles the conversions instantly.

Risk-reward analysis separates profitable traders from the rest. A 1:3 risk-reward ratio means you can be wrong 70% of the time and still make money. But you need to calculate it accurately for every trade.
