Decimal odds show how many times your stake is returned on a winning bet. Odds of 1.80 pay 1.80 per unit staked. The payout already includes the original stake; it is not all profit.
How to calculate payout and profit
For a standard bet without bonuses or deductions: payout = stake × odds; profit = stake × (odds − 1). The amounts below are hypothetical examples of calculation, not suggested stakes.
Net profit: 5
Net profit: 8
Net profit: 15
If the selection loses, a standard bet pays zero and the stake is lost. Refunds, partial settlements and bonus bets may follow different rules.
How odds relate to probability
The reciprocal of the odds gives implied probability: 1 / odds × 100%. Odds of 2.00 imply 50%; 1.80 implies about 55.56%. This is a probability reflected in the price, not a proven likelihood.
Consider two mutually exclusive outcomes, each priced at 1.90. Their implied probabilities total about 105.26%. The excess over 100% is the market overround. It does not mean the bookmaker necessarily earns 5.26% on every individual bet.
Three common mistakes
- Treating payout as net profit and adding the stake twice.
- Treating low odds as a guaranteed result.
- Comparing different markets: regulation time, qualification and results including overtime may settle differently.
What to check before calculating
Check the odds format, market name, period covered and cancellation rules. For a free bet, check whether its nominal stake is returned. Identical numbers on screen do not make different terms equivalent.
Frequently asked questions
Do odds of 2.00 mean double the profit?
No. The total payout is twice the stake; net profit equals one stake.
Can the true probability be determined from odds alone?
No. Odds reflect the bookmaker’s price. An independent estimate requires data and assumptions that may be wrong.
