Equal-payout stake allocation
Enter the best price you want to evaluate for each distinct outcome and a total stake. Let S be the sum of reciprocal decimal odds. Each theoretical stake is total stake × (1 / odds) / S. The common payout is total stake / S.
A sum below 100% produces a positive theoretical result before fees, rounding, limits, and settlement differences. A sum of 100% breaks even. A sum above 100% produces a loss under this allocation.
Worked example
For two outcomes at 2.10 each and a total stake of 100, allocate 50 to each side. Either winning outcome pays 105, producing a theoretical net result of 5 before costs.
Questions
Can I compare any two prices?
The outcomes must cover the same event and every possible settlement result. Check regulation versus extra time, void rules, cancellations, fees, and currency. A team's NO prediction contract does not automatically cover the opposing 1X2 outcome.
Why can the actual result differ?
A price can change before execution. Limits, partial fills, stake rounding, fees, and incompatible void rules can change the result. This calculator evaluates your inputs and has no connection to betting accounts.
