What this tool calculates
Find the minimum long-run win rate needed for a bet to cover its losses, including commission charged only on winning profit.
Break-even probability = 1 ÷ [1 + (decimal odds − 1) × (1 − commission rate)].
Results are informational and depend on the entered assumptions.
Worked example
At decimal odds 2.10 with 0% commission, the threshold is 47.62%. With commission, the required rate rises.

| Output | Display rounding occurs after calculation. |
Tips and limitations
Commission is applied to winning profit, not returned stake. Pushes and voids are excluded; model them separately if they occur often.

FAQ
What inputs does the Break-Even Win Rate Calculator use?
It uses only the values shown in the calculator and performs the calculation locally in your browser.
When can the displayed settlement differ from my bet slip?
Operator rules for voids, timing, statistics, deductions, and market definitions can differ. The selected assumptions are stated beside the result.
Are intermediate values rounded?
No. The calculator keeps JavaScript numeric precision during calculation and rounds only the displayed figures.
Does this result predict whether a bet will win?
No. It explains arithmetic or settlement for supplied inputs and does not forecast an event.
Can I use a different currency?
Yes. Monetary fields use neutral units, so use one currency consistently across every amount.
