Accumulator (Parlay) Calculator
Enter decimal odds for each selection to see the combined odds, potential return and potential profit. Calculations run in your browser — nothing is sent anywhere.
How the math works
Combined odds = the product of every selection's decimal odds multiplied together. Potential return = stake × combined odds. Potential profit = potential return − stake.
Worked example
Three selections at decimal odds 1.85, 2.10 and 1.60, with a $10 stake: combined odds = 1.85 × 2.10 × 1.60 = 6.216. Potential return = $10 × 6.216 = $62.16. Potential profit = $62.16 − $10 = $52.16 — but only if all three selections win.
Limitations
- This tool accepts decimal odds only. Convert fractional or American odds first with our odds converter.
- Every selection must win for an accumulator to pay out — one loss loses the whole bet, regardless of the others.
- This calculator does not account for taxes, fees, or any platform-specific rules beyond the wagering-requirement example shown.
