How betting odds work
South African sites price in decimal odds. The number is a multiplier on your total return, stake included — which is the part most people get wrong when they first start.
Reading a decimal price
Decimal odds of 2.50 mean a winning R100 bet returns R250 in total: R150 profit plus your R100 stake back. Multiply the stake by the odds and you have the return, not the profit.
Anything below 2.00 means the selection is favoured — a winning bet returns less than double. Anything above 2.00 means it is against the odds.
Odds are not probability
You can convert a price to an implied probability by dividing 100 by the decimal odds. At 2.50 that is 40%. Do this for every outcome in a market and the total comes to more than 100%.
That excess is the operator margin, sometimes called the overround. It is how a bookmaker makes money regardless of the result, and it is why consistently beating the market is hard — you are not just predicting the outcome, you are beating the price plus the margin.
Why prices move
- Team news — confirmed lineups, injuries and rotation.
- Money — where the stakes are going, which shifts a book regardless of merit.
- Conditions — weather, surface, altitude.
- Time — prices drift or shorten as an event approaches and information firms up.
