Worked example in naira
You stake ₦1,000 on a 3-leg accumulator at 1.50, 2.00 and 1.80. Combined odds are 1.50 × 2.00 × 1.80 = 5.40, so the return if all three win is ₦1,000 × 5.40 = ₦5,400 (₦4,400 profit). If the 2.00 leg is void, it drops out: 1.50 × 1.80 = 2.70, so the return is ₦2,700. A half-won Asian line at 1.90 on ₦1,000 returns ₦1,000 × (1 + 1.90) ÷ 2 = ₦1,450.
How the calculator works
- Won: stake × decimal odds.
- Lost: returns ₦0 (one lost leg loses the whole accumulator).
- Void: the leg counts as odds of 1.00 and drops out.
- Half-won: half wins at full odds, half is refunded: × (1 + odds) ÷ 2.
- Half-lost: half is lost, half is refunded: × 0.5.
- Each-way: two bets of your stake (win + place), so the total stake doubles. Place odds = 1 + (odds − 1) × place terms (1/4 or 1/5).
Implied probability is 100 ÷ combined decimal odds. It includes the bookmaker margin, so it is not the true chance of winning. Returns shown before any tax or bookmaker rules (e.g. max payout). Check terms with your licensed bookmaker. 18+ only.
FAQ
How do I calculate an accumulator return?
Multiply all the decimal odds together, then multiply by your stake. ₦1,000 at 1.50, 2.00 and 1.80 returns ₦5,400.
What happens to a void leg in an accumulator?
It is treated as odds of 1.00, so it drops out and the rest of the slip still stands.
What is a half-won bet?
On Asian lines, half your stake wins at full odds and half is refunded. ₦1,000 at 1.90 half-won returns ₦1,450.
Does the calculator include tax or maximum payouts?
No. Returns are shown before any tax or bookmaker rules such as max payout. Check the terms with your licensed bookmaker.
Do you store what I enter?
No. The calculator runs in your browser and uses no cookies or tracking.
