How betting odds work

Editorial standards

Betting odds tell you two things: how much a winning bet pays and how likely the bookmaker thinks the result is. African bookmakers show decimal odds by default, and a decimal price is simple to read, because your stake multiplied by the odds gives the full return, stake included.

Decimal odds and implied probability

Say Asante Kotoko are 2.40 to beat Hearts of Oak. A GH₵20 bet returns GH₵48 if Kotoko win, and your profit is GH₵28, since GH₵20 of the return was your own stake.

A lower number means the bookmaker expects that result more. Odds of 1.30 mark a strong favourite and 6.00 an outsider, while 1.00 would only hand the stake back.

Dividing 1 by the decimal odds gives the implied probability. Odds of 2.40 imply 41.7%, and odds of 1.30 imply 76.9%. That figure is the price’s opinion about the match. When your own estimate of a team’s chance sits higher, the price is in your favour, the idea behind value betting.

The bookmaker’s margin

The implied probabilities of every outcome in a market add up to more than 100%, and the extra is the bookmaker’s margin.

Take a Kenyan Premier League match between Gor Mahia and AFC Leopards priced at 2.10 home, 3.10 draw and 3.60 away. The implied probabilities are 47.6%, 32.3% and 27.8%, which add up to 107.7%, so the margin is 7.7% and it sits inside every price you take.

A lower margin means better prices for you. Comparing the same match at a few licensed sites before staking pays off, because a few points of margin on a weekly stake add up over a season.

Fractional, American and moving prices

British and American sites, and some tipster posts, use other formats:

  • Fractional 7/5 wins 7 for every 5 staked, which is 2.40 in decimal.
  • American +140 means a 100 stake wins 140, also 2.40 in decimal.
  • American −250 means you stake 250 to win 100, which is 1.40 in decimal.

Our odds converter switches between all three and shows the implied probability.

Prices move after team news, injuries, weather and the weight of money. A Super Eagles price set on Monday looks very different by match day when a key striker is ruled out.

A shared slip or booking code loads at the current price, so a slip showing 25.00 when shared can sit at 19.00 when you stake. Small changes matter most in accumulators, where betting odds multiply together.
