Enter decimal odds (e.g. 1.85). Combined odds = every leg multiplied together. All legs must win for an accumulator to pay out.
How to Use the Accumulator Calculator
Enter the decimal odds for each selection in your accumulator, add or remove legs as needed, and type in your stake in Naira. The calculator instantly shows your combined odds, total payout, profit, and the implied probability of the full acca landing. Because every Nigerian bookmaker — from Bet9ja to SportyBet to 22Bet — displays decimal odds by default, you can copy odds straight from your bet slip.
How Accumulator Odds Are Calculated
An accumulator multiplies the odds of every leg together. Three selections at 1.80, 2.10 and 1.65 give combined odds of 1.80 × 2.10 × 1.65 = 6.24. A ₦1,000 stake would return ₦6,240 — but every single leg must win. One losing leg loses the whole bet, which is why the implied probability figure matters: it shows how likely the full acca really is, not how it feels.

Where to Place Your Accumulator
Acca-friendly features vary by bookmaker. 22Bet’s welcome bonus is built around accumulators — the rollover requires 3+ selections at odds of 1.40 or higher, so new players effectively get bonus funds designed for acca betting. Mozzartbet’s free-bet package requires 4+ leg combos, making it another natural fit for accumulator players.
