Slippage Impact Calculator

Model the impact of slippage on your trades. Compare best-case, expected, and worst-case scenarios to understand real execution costs.

Slippage is the gap between the price you asked for and the price you got. Market orders and triggered stops fill at the next available price, so it works against you; limit orders (entries and take-profits) fill at their price or not at all.

Trades per week

Assumes the same slippage on the entry and on the stop, none on the take-profit (a limit order). A limit entry removes the entry slippage but may not fill when price moves fast; nothing removes stop slippage except a guaranteed stop, which brokers charge for.

Slippage Impact Calculator FAQ

What is slippage in forex?

Slippage is the difference between your intended entry price and the actual fill price. It typically occurs during high volatility or low liquidity periods.

How much slippage is normal?

For major pairs during liquid sessions, 0-1 pip of slippage is normal. During news events or off-hours, slippage can be 3-10+ pips.

How can I reduce slippage?

Trade during high-liquidity sessions (London/New York overlap), use limit orders instead of market orders, avoid trading during major news releases, and choose brokers with fast execution speeds.
