Accumulator / Parlay Calculator
For readers checking a stated accumulator payout. The calculation makes the all-legs-win condition explicit.
Examples are hypothetical. CU = currency units. Use one consistent currency wherever CU appears. No live prices or provider data are fetched.
How to read the result
The return applies only if every entered leg wins and the operator pays the simple product. This calculator does not predict joint win probability or model correlated pricing, void legs, dead heats, boosts or taxes.
Formula
- Combined decimal odds D = product of all leg odds.
- Gross return = stake × D, including the original stake.
- Net result if all legs win = gross return − stake; reciprocal price = 100/D. Multiplying prices for payout does not itself require independence.
Worked example
D = 1.80 × 2.10 × 1.65 = 6.237; 10 CU × 6.237 = 62.37 CU gross return; net result = 52.37 CU.
