How to Calculate a Bet Payout: Formulas and Examples
Work out your bet payout from stake and odds in seconds. Decimal, fractional and American formulas, accumulator maths and worked rand examples.
To calculate a bet payout, multiply your stake by the decimal odds. A R100 bet at odds of 1.55 pays R155 in total: R55 profit plus your R100 stake back. News24 uses the same odds × stake logic in its betting guide for South African readers. Everything else on this page is a variation: converting fractional or American odds into decimals first, then multiplying, or chaining several selections together for an accumulator.
TL;DR
- Payout = stake × decimal odds. Profit = payout − stake.
- Fractional odds: divide the top number by the bottom, add 1, then use the decimal formula. American odds: +200 means R100 profit on a R200… no, the reverse: R100 staked wins R200 profit.
- Accumulator: multiply every selection’s decimal odds together, then multiply by your stake. One lost leg loses the whole bet.
- The number on your slip is the starting point. Voided legs, bonus terms and rules for specific products can change what lands in your account.

Payout versus profit: the distinction that trips people up
Bookmakers and calculators show two numbers, and mixing them up is the most common mistake beginners make.
- Total payout (also called total return) is everything the bookmaker credits you when the bet wins, including your stake.
- Profit (or net winnings) is the payout minus your stake. It is what you are actually ahead.
Take that R100 at 1.55 again. The payout is R155. The profit is R55. If you read “R155” as your win, you have overstated it by exactly your stake. When a bet loses, you get nothing back, so the stake is the most you can lose on a standard single bet.
The core formula with decimal odds
Decimal odds are the format most South African bookmakers show by default, and they make the maths simplest.
Payout = stake × decimal odds
Profit = payout − stake, or equivalently stake × (odds − 1)
Worked examples
| Stake | Decimal odds | Payout | Profit |
|---|---|---|---|
| R50 | 1.80 | R90 | R40 |
| R100 | 1.55 | R155 | R55 |
| R200 | 2.40 | R480 | R280 |
| R100 | 7.50 | R750 | R650 |
| R20 | 12.00 | R240 | R220 |
A quick sanity check: decimal odds can never be below 1.00. At exactly 1.00 you would only get your stake back. Anything above 1.00 gives a profit.
Reading the odds as a probability
Dividing 1 by the decimal odds gives the bookmaker’s implied probability. Odds of 2.40 imply 1 ÷ 2.40 = about 41.7%. That figure is useful for the bigger question of whether a price is worth taking, which we cover in our guide to value betting and spotting odds worth taking.
Fractional odds: convert, then multiply
Fractional odds (5/2, 11/4, 1/3) are common in horse racing and in UK-style coverage. The fraction already describes profit relative to stake: in 5/2, you win R5 profit for every R2 staked.
Two routes give the same answer.
Route 1, convert to decimal. Divide the first number by the second and add 1. Football Ecology’s converter guide gives the same rule: 5/2 becomes 3.50. Then use stake × decimal odds.
Route 2, calculate profit directly. Profit = stake × (top ÷ bottom). Payout = profit + stake.
Example: R100 at 5/2
- Decimal: 5 ÷ 2 = 2.5, plus 1 = 3.50
- Payout: R100 × 3.50 = R350
- Profit: R350 − R100 = R250
Example: R90 at 1/3 (odds-on)
- Decimal: 1 ÷ 3 = 0.333, plus 1 = 1.333
- Payout: R90 × 1.333 = R120
- Profit: R30
Odds-on prices, where the fraction is smaller than 1/1, always pay less profit than your stake. That is the bookmaker saying the outcome is a favorite.
American (moneyline) odds: plus and minus
You will meet American odds on international sites, in US sports coverage and in many calculators. They use a base of 100.
- Positive odds (+200): the number is the profit on a 100 stake. Investopedia’s explainer puts it this way: +200 means a $100 bet wins $200 profit, for a $300 payout. In rand terms, R100 at +200 returns R300.
- Negative odds (−150): the number is the stake you need to win 100 profit. R150 at −150 wins R100 profit, for a R250 payout.
Converting American odds to decimal
- Positive: decimal = (odds ÷ 100) + 1. So +200 is 3.00.
- Negative: decimal = (100 ÷ the number without its minus sign) + 1. So −150 is (100 ÷ 150) + 1 = 1.667.
Once you have the decimal, the usual formula works for any stake. R60 at +200 is R60 × 3.00 = R180 payout, R120 profit.
What does +3000 mean?
It is a long shot. A 100 stake wins 3,000 profit, so a $100 bet at +3000 returns $3,100 in total. In decimal that is 31.00. R20 at +3000 pays R620, of which R600 is profit. The implied probability is about 3.2%, which is why prices like this attach to outsiders and outright markets.
Quick conversion table
| Decimal | Fractional | American |
|---|---|---|
| 1.50 | 1/2 | −200 |
| 2.00 | 1/1 | +100 |
| 3.00 | 2/1 | +200 |
| 3.50 | 5/2 | +250 |
| 31.00 | 30/1 | +3000 |
Accumulators: multiply the odds, then the stake
An accumulator (acca, or multi-bet) combines several selections into one bet. All legs must win. A betting-maths guide to accumulators describes the method: multiply the decimal odds of every selection to get the combined odds, then apply your stake.
Worked example: a three-leg soccer acca
Say you pick three results at 1.55, 2.10 and 1.80, and stake R100.
- Combined odds: 1.55 × 2.10 × 1.80 = 5.859
- Payout: R100 × 5.859 = R585.90
- Profit: R585.90 − R100 = R485.90
Compare that with betting R100 on each leg separately as singles. If all three win, you collect R155 + R210 + R180 = R545 from R300 staked, a profit of R245. The acca turned a R100 stake into R485.90 profit, but it only needed one wrong result to pay nothing. If two of the three singles win, you would still be ahead.
Why accas get risky fast
The combined implied probability multiplies too. Legs at 1.55, 2.10 and 1.80 imply roughly 64.5%, 47.6% and 55.6%. Together that is about 17%. Adding a fourth and fifth leg pushes the payout up and the chance of collecting down quickly.
When a leg is voided
If a match is postponed or a selection is voided, most bookmakers treat that leg as odds of 1.00 and recalculate the payout from the remaining legs. Rules differ by operator, so read the house rules on the slip before you stake. Some sites also let you remove a not-yet-started leg from an open multi, which changes the combined odds.
Other things that change what you actually receive
The formula gives the gross figure printed on your slip. Check these before you count the money.
- Bonus bets and free bets. A free bet usually pays profit only, not the stake. A R100 free bet at 3.00 returns R200, not R300. Bonus funds also often carry rollover conditions, explained in our guide to wagering requirements in South Africa.
- Dead heats and tied results. Your stake may be split, so payout shrinks proportionally.
- Pool and tote-style products. Soccer pools do not use fixed odds at all. Dividends depend on how many winners share the pot, as set out in our soccer pools payout rules and the comparison of SportStake 13 and TAB Soccer 13.
- Tax. Under SARS guidance, betting services are taxable supplies, and a vendor may deduct 14/114 of amounts paid as prizes or winnings. That is the operator’s VAT position, not a deduction from your slip. For what it means for your own winnings, see our explainer on the 20% operator tax.
- Withdrawal timing. A win on the slip is not cash in your bank until you withdraw. Account verification matters here, so complete your FICA checks early.
A five-step routine you can run on any slip
- Identify the odds format. Convert to decimal if needed.
- Multiply stake × decimal odds. That is your total payout.
- Subtract the stake for profit.
- For an acca, multiply all leg odds first.
- Read the slip for bonus, void or dead-heat terms, then compare the figure with what the bookmaker shows as potential return. They should match. If they don’t, find out why before you confirm.
Where we come in
If you are choosing where to place the bet, we review licensed South African bookmakers on bonus terms, payout handling and safety. Our ratings come from hands-on, real-money testing against published criteria. If you want to see how a licensed operator presents odds, returns and withdrawals, start with our TAB review, or browse the full list on the Bet Mzansi homepage.
Before you sign up anywhere, confirm the operator holds a South African licence. Our guide to whether online betting is legal in South Africa shows how to check.
Our view: calculate before you click
We test bookmakers with real money, so we see the gap between expected and actual payouts regularly. Usually it is nothing sinister. It is a bettor who read the profit as the payout, or who forgot that a free bet does not return its stake, or who added a fifth leg to an acca without realising the combined probability had fallen below one in ten.
Our advice is simple. Do the sum yourself before you confirm any bet, even if the slip shows it. It takes ten seconds, and it teaches you what a price really says. Odds are a statement of how likely the bookmaker thinks something is, plus its margin. A payout figure that looks exciting is often a longshot dressed up as an opportunity.
Set your stake before you look at the potential return, not after. Decide what you can afford to lose, because that is the only number guaranteed to be real. And if betting stops being fun, stop. South African operators must offer responsible gambling tools, and the National Responsible Gambling Programme runs a helpline for anyone who needs it.

FAQ
How do you work out a bet?
Multiply your stake by the decimal odds to get the total payout, then subtract the stake to see your profit. A R100 bet at 1.55 returns R155, of which R55 is profit. If the odds are fractional or American, convert to decimal first.
What does +200 odds to win mean?
It is American odds meaning a 100 stake wins 200 profit, for a total return of 300. In rand, R100 at +200 pays R300. The decimal equivalent is 3.00, and the implied probability is about 33%.
What does +3000 odds to win mean?
It means a 100 stake would win 3,000 profit, a total of 3,100 returned. That is 31.00 in decimal odds and roughly a 3.2% implied chance. Bookmakers price outsiders and outright winners like this.
Is the payout the same as my winnings?
No. The payout includes your stake, while winnings or profit exclude it. On a R200 bet at 2.40, the payout is R480 and the profit is R280. Free bets are the exception, because they usually pay profit only.
How do I calculate an accumulator payout?
Multiply the decimal odds of all selections, then multiply by your stake. Three legs at 1.55, 2.10 and 1.80 give combined odds of 5.859, so R100 pays R585.90. If any leg loses, the whole bet loses.
