Lay bet calculator
Laying at an exchange bets that an outcome will not happen. Backing 100 at 3.00 and laying at 3.10 with 2% commission needs a lay stake of 97.40 and a liability of 204.55; the result is -4.55 whichever way it goes.
How it works
- Equal-result lay stake = back stake × back odds / (lay odds - commission).
- Liability = lay stake × (lay odds - 1): what you pay if the outcome happens. Keep it in your exchange account.
- If the back bet wins: back profit - liability. If it loses: lay stake × (1 - commission) - back stake. The calculator makes the two equal.
Laying off a free bet, stake returned or not? The matched betting calculator handles all three cases.
