Reverse Kelly Calculator
Back-calculate your implied edge based on bet size, odds, and bankroll
What is Reverse Kelly?
The Reverse Kelly Calculator works backward from your bet size to determine the implied edge you're giving yourself on a bet. While the standard Kelly Criterion tells you how much to bet based on your edge, the Reverse Kelly tells you what edge you're implying based on how much you're betting. This can help you understand if your betting patterns align with your actual confidence levels.
