Accumulator Calculator — Multi/Parlay Returns
Compound a stake across up to 8 legs to see the final return and profit.
An accumulator (or “multi”) rolls your stake and winnings from one leg onto the next. Every leg must win for the bet to pay, and the returns multiply — which is why small stakes can return large amounts, and why they’re hard to land.
Enter a stake and the odds for each leg and the calculator shows the running return after each, the final payout, profit and ROI.
How it works
Each leg multiplies the running total by its decimal odds. Four $1.50 shots aren’t a 50% return — they compound to about 5× your stake.
The full-precision multiplication is rounded to the cent only at the end, so the figure matches what a bookmaker would pay.
final return = stake × odds₁ × odds₂ × … × oddsₙ
Worked example
- 1,500c × 1.60 × 1.90 × 1.70 × 1.80 × 1.90 = 26,511.84c
- Final return: $265.12
- Profit: $250.12
This is the same maths the in-app accumulator uses, rounded to the cent once at the end.
FAQ
- What is an accumulator?
- A single bet combining several selections where all must win; the stake and winnings roll from each leg onto the next.
- How many legs can I add?
- Up to 8 here. More legs multiply the potential return but sharply cut the chance of the whole bet landing.
- Why are accumulators risky?
- Because every leg must win. The compounding return is the reward for a low overall probability — manage your bankroll accordingly.
