What Is Value Betting?
A value bet exists when the true probability of an outcome is higher than the implied probability of the odds. If you believe a team has a 50% chance of winning, but the odds imply only 40%, that's theoretical value.
The Formula
Value = (Your Probability × Odds) - 1
A positive result indicates value; negative means no value.
The Reality Check
Identifying value requires accurately estimating true probabilities, something even professional analysts struggle with. Bookmakers employ sophisticated models; beating them consistently is extremely difficult.
Most bettors who believe they've found value have simply misjudged the probability. Use this tool to understand the concept, but be realistic about your ability to out-analyze the market.
