| Check | Meaning |
|---|---|
| Inputs | Use values from one consistent market or settled event. |
| Output | The result follows the formula and assumptions stated on this page. |
Real bets may not be independent and your true win probability can change. A likely losing streak does not justify increasing stakes or chasing losses.
Keep stakes proportionate to what you can afford to lose. No calculator removes betting risk.
The calculator uses only the values displayed in its input card. Each value is validated before a result is shown.
The calculation keeps JavaScript numeric precision internally and rounds only the displayed figures to practical decimal places.
No. The stated assumptions are applied, while voids, promotions, deductions, taxes, and operator-specific rules must be checked separately.
No. It evaluates the entered numbers or settled score; it does not predict an event or provide a betting signal.
Differences can come from odds changes, currency rounding, push or void treatment, commission, bonus terms, or a different calculation convention.
