What is a value bet?

FootballFanager team · Updated 12 November 2026

A value bet is a bet where the odds pay more than the real chance of the outcome is worth. If a team has a 50 % chance of winning, the fair odds are 2.00. If a bookmaker offers 2.20, that is value: over many such bets you would expect to make about 10 % on your stakes.

How to work it out

Value = odds × probability − 1. With odds 2.20 and a 50 % chance: 2.20 × 0.50 − 1 = +0.10, or a 10 % edge. If the result is negative, the bet is poor value however likely it is to win.

Where the probability comes from

The hard part is the probability. Two common ways are your own model, or the price of the sharpest bookmakers with the margin removed. We use the second for our value tips: when a bookmaker pays more than that fair price, it is listed. Our implied probability calculator shows how the margin is removed.

Value is not the same as a likely winner

A value bet at odds of 4.00 loses most of the time. That is fine if the price is right: you are paid enough when it wins. A short-priced favourite can be poor value even if it wins often.

How much to stake

Keep stakes small and steady. The Kelly criterion calculator sizes a stake from your edge; most bettors use half or quarter Kelly.

Frequently asked questions

Does a value bet always win?

No. Value is about the price over many bets. A single value bet can easily lose.

What edge is realistic?

A few percent. Very large edges are often price errors that bookmakers void or correct.
