How to Calculate Your Winnings: Formulas and Worked Examples
Return, profit and stake in one formula, then the awkward cases: accumulator legs, system combinations, voided selections, half-stake quarter handicaps and the stake needed to win a set amount.
Every payout comes from one multiplication: stake × decimal odds = total return. Subtract the stake and you have the profit. Accumulators, systems, refunded legs and quarter handicaps that settle at half a stake are all that same line applied more than once, and this page works through each case in naira at a ₦500 stake.
In short.
- Return = stake × odds. Profit = return − stake. Decimal odds already include your money back.
- An accumulator multiplies the legs first, then the stake: 1.55, 2.05, 1.72 and 2.40 give 13.12.
- A system is several tickets. Divide your money by the number of combinations before staking.
- A voided leg is re-priced at 1.00 — the same as dividing the accumulator price by that leg.
- To win a chosen amount, divide it by (odds − 1). Winning ₦1,000 at 1.30 costs ₦3,333 in risk.
Part of the series
If the prices themselves are still unfamiliar, start with how to read betting odds. The three ticket formats are compared in single, accumulator and system bets; this page is the arithmetic behind them.
Return, profit and stake are three different numbers
Odds of 2.30 do not mean you win 2.3 times your money. They mean ₦1 comes back as ₦2.30, of which ₦1 was already yours. A ₦500 stake at 2.30 returns ₦1,150 and profits ₦650 — and ₦650 is the figure for your log.
| Odds | Return on ₦500 | Profit | Profit per ₦1 risked |
|---|---|---|---|
| 1.35 | ₦675 | ₦175 | ₦0.35 |
| 1.83 | ₦915 | ₦415 | ₦0.83 |
| 2.10 | ₦1,050 | ₦550 | ₦1.10 |
| 4.20 | ₦2,100 | ₦1,600 | ₦3.20 |
| 7.50 | ₦3,750 | ₦3,250 | ₦6.50 |
Multiplying the legs of an accumulator
An accumulator pays only if every selection lands, and its price is the product of the legs. Multiply the prices first, keep the full result, apply the stake at the end.
Example. Four legs at 1.55, 2.05, 1.72 and 2.40. 1.55 × 2.05 = 3.1775; × 1.72 = 5.4653; × 2.40 = 13.1167. The slip displays 13.12. A ₦500 stake returns ₦500 × 13.1167 = ₦6,558.35, a profit of ₦6,058.35.
Note the rounding. The displayed 13.12 suggests ₦6,560, about ₦2 more than settlement pays: operators keep the unrounded product and round only the payout.
Counting the combinations in a system
A system is not one ticket. A 2/3 system is three separate doubles, each carrying its own stake, so your outlay is three times the unit. The count comes from n! ÷ (k! × (n − k)!).
| System | Combinations | Total stake at ₦500 a line |
|---|---|---|
| 2 from 3 | 3 doubles | ₦1,500 |
| 3 from 4 | 4 trebles | ₦2,000 |
| 2 from 5 | 10 doubles | ₦5,000 |
| 3 from 6 | 20 trebles | ₦10,000 |
On a ₦12,000 monthly budget the last row spends the month in one afternoon, which is why system stakes are usually a fraction of a unit.
Example. A 2/3 system on legs priced 1.80, 2.20 and 2.50, ₦500 per double, ₦1,500 staked. The doubles are 3.96, 4.50 and 5.50. All three land: ₦500 × (3.96 + 4.50 + 5.50) = ₦6,980, a profit of ₦5,480. Only 1.80 and 2.20 land: one double completes, ₦500 × 3.96 = ₦1,980, a profit of ₦480. One leg or none: ₦0.
Two winners out of three produce ₦480 to ₦1,250 of profit depending on which pair landed: a system has no single payout, it has one per outcome.
When a leg is voided and priced at 1.00
A cancelled market does not kill the ticket. The leg is re-priced at 1.00, which multiplies by nothing, and the rest settles normally. On the four-leg slip above, voiding the 2.40 leg gives 13.1167 ÷ 2.40 = 5.4653.
| The 2.40 leg | Ticket price | Return on ₦500 |
|---|---|---|
| Wins | 13.1167 | ₦6,558.35 |
| Voided at 1.00 | 5.4653 | ₦2,732.65 |
| Loses | — | ₦0 |
On a single, a void is simply a refund: stake back, profit zero. What it never does is rescue a losing accumulator — the other legs still have to land.
Half-stake settlement on quarter handicaps
Quarter lines such as −0.25 or −0.75 split your stake equally across the two neighbouring lines, which is why they can pay half a win or lose half a stake. The lines themselves are covered in handicap betting explained.
Example. ₦500 on −0.75 at 2.05 is really ₦250 on −0.5 and ₦250 on −1. Win by two or more: both halves win, ₦500 × 2.05 = ₦1,025, profit ₦525. Win by exactly one: the −0.5 half pays ₦250 × 2.05 = ₦512.50 and the −1 half refunds ₦250, so ₦762.50 comes back — profit ₦262.50, exactly half the full win.
The mirror case loses half. At −0.25 with a price of 2.00, ₦500 becomes ₦250 on level ball and ₦250 on −0.5.
| Result | Half on 0 | Half on −0.5 | Return |
|---|---|---|---|
| Team wins | ₦500 | ₦500 | ₦1,000 |
| Draw | ₦250 refunded | Loses | ₦250 |
| Team loses | Loses | Loses | ₦0 |
A draw costs ₦250, not ₦500. This is also why your history can show a settled bet returning neither zero nor the full payout.
Working backwards: the stake that wins a set amount
Divide the target profit by (odds − 1). For a fixed total back instead: stake = target return ÷ odds, so ₦2,000 back at 1.60 costs ₦1,250.
| Odds | Stake to profit ₦1,000 | Share of a ₦12,000 budget |
|---|---|---|
| 1.30 | ₦3,333 | 28% |
| 1.50 | ₦2,000 | 17% |
| 2.00 | ₦1,000 | 8% |
| 3.00 | ₦500 | 4% |
| 4.50 | ₦286 | 2% |
Read the top row slowly: a ₦1,000 target at 1.30 puts more than a quarter of the month on one result that fails roughly one time in four. Set the stake from your bank, as in bankroll management, and let the profit be whatever the price produces.
Common mistakes
- Adding odds instead of multiplying. Three legs at 2.00 give 8.00, not 6.00.
- Reading decimal odds as profit. At 1.20 a ₦500 stake profits ₦100, not ₦600.
- Applying a boost to the return. A 10% boost on a ₦650 profit adds ₦65, not ₦115.
- Staking a system as one ticket. ₦500 on a 3/6 system is ₦10,000 out of your balance.
Practise on live prices: open today's fixtures, take three and work out all three ticket types before staking.
FAQ
Why is my payout a few naira less than the slip predicted?
Because the displayed accumulator price is rounded to two decimals while settlement uses the unrounded product of the legs. On the four-leg example above, 13.12 on screen suggests ₦6,560, but the true price of 13.1167 pays ₦6,558.35. The gap widens slightly with more legs.
How do I calculate a bet placed at fractional odds?
Convert first: numerator ÷ denominator + 1. Odds of 13/10 become 2.30, so ₦500 returns ₦1,150. You can also work in fractions directly — 13/10 means ₦13 profit for every ₦10 risked, which on a ₦500 stake is ₦650 profit and the same ₦1,150 back.
What happens if two legs of my accumulator are voided?
Both are re-priced at 1.00 and the ticket settles on what remains. Divide the original price by both: a 13.1167 slip that loses the 2.40 and 1.72 legs to voids becomes 3.1775, so a ₦500 stake returns ₦1,588.75 provided the other two legs land.
Does a half-lost quarter handicap count as a loss in my records?
Record the money, not the label. A −₦250 result on a ₦500 stake is half a unit lost and should be logged as −₦250. Counting it as a full loss makes your yield read worse than it is; ignoring it makes the month look better than it was.
