Layer's Aid betting calculator

The Layer's Aid calculator calculates:

• Your liability on a Lay bet
• How much you can afford to lay for a given liability

Calculating your liability on a Lay bet
This shows that if you want to lay a selection for £50 at 3.75, your liability would be £137.50. In other words, unless you had other outstanding positions in the same market, you would need to deposit £137.50 into your betting exchange account to cover the bet.


Calculating how much you can afford to lay for a given liability
In this example, you have £100 in your betting exchange account and would like to lay a horse for as much as you can at 1.21. Layer's Aid shows you that you can afford to lay £476.19 at that price.
