Football Betting Odds Converter

Convert football betting odds between decimal, fractional and American formats — and see the implied win probability.

Football Betting Odds Converter

A football odds converter changes betting odds from one format to another so you can compare prices across bookmakers. The three main formats are decimal (popular in Europe, e.g. 2.50), fractional (used in the UK and Ireland, e.g. 6/4) and American or moneyline odds (e.g. +150). They all describe the same thing — how much a winning bet returns — just written differently.

This free tool instantly converts any football odds between decimal, fractional and American, and shows the implied probability: the chance of that outcome the odds represent. For example, decimal odds of 2.50 imply a 40% chance (100 ÷ 2.50). Comparing the implied probability with your own estimate is how bettors spot value. Everything runs in your browser, with no sign-up and no data sent anywhere. Just type the odds, pick the format you entered, and read off every other format plus the percentage. It is handy for comparing Premier League, Champions League or World Cup prices that different sites display in different formats.

Frequently asked questions

Subtract 1 from the decimal odds and express the result as a fraction. For example, decimal 2.50 minus 1 = 1.5 = 3/2 (or 6/4). This converter does it automatically and reduces the fraction for you.

Implied probability is the chance of an outcome that the odds represent. Divide 100 by the decimal odds: 100 ÷ 2.50 = 40%. If you think the real chance is higher than the implied probability, the bet may have value.

American odds show how much you win on a 100 stake. Positive odds like +150 mean a 100 bet returns 150 profit; negative odds like -200 mean you must stake 200 to win 100. They are common with US sportsbooks.
