What is a betting calculator?

A betting calculator — also known as an odds calculator — is a tool that lets you see what your returns will be when you bet a stake on particular odds. They offer an easy way to see exactly what your profit will be without the need to do any maths. You can typically use a betting odds calculator as a quick reference point before you place any bets.
