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.

Selections

Enter at least 2 valid selections and a stake, then press Calculate.

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.

Educational tool only. This calculator performs mathematics on the numbers you enter — it does not predict outcomes, does not represent DBBet's actual odds on any real event, and is not betting advice. Gambling involves financial risk. Only participate where legal and within limits you can afford. See our Responsible Gambling page.

Frequently asked questions

Does combining selections make the bet more likely to win?
No. Combining selections into an accumulator does not change the underlying chance of any individual selection winning — every leg still has to win for the accumulator to pay out. This calculator is mathematical only, not a prediction.
Is this calculator specific to DBBet?
The math works for any accumulator bet on any platform. The wagering-requirement check uses DBBet's own real, published welcome-bonus terms as a real example — see our Bonuses page for the full terms.
Does a higher potential return mean a better bet?
No — potential return only reflects the odds and stake you entered, not how likely the outcome actually is. A longer accumulator usually means lower overall odds of winning, even though the potential payout is higher.
