What this tool calculates
Estimate the expected net value of a stake-refund promotion using your win probability and the realistic cash value of the refund credit.
EV = p × stake × (odds − 1) + (1 − p) × [−stake + stake × refund conversion rate].
Results are informational estimates. Confirm final grading, limits, and promotional terms with the operator.
Worked example
A 100 stake at 2.50, 40% win probability and a refund worth 70% has win profit 150, loss value −30 and expected net value 42.
| Check | Meaning |
|---|---|
| Inputs | Use values from one consistent market or settled event. |
| Output | The result follows the formula and assumptions stated on this page. |
Tips and limitations
“Risk-free” is promotional language, not a guarantee. Check whether the refund is cash or bonus credit, whether stake is returned, and what wagering restrictions apply.
Keep stakes proportionate to what you can afford to lose. No calculator removes betting risk.
FAQ
What inputs does the Risk-Free Bet Value Calculator require?
The calculator uses only the values displayed in its input card. Each value is validated before a result is shown.
When are the results rounded?
The calculation keeps JavaScript numeric precision internally and rounds only the displayed figures to practical decimal places.
Does this result include bookmaker-specific settlement rules?
No. The stated assumptions are applied, while voids, promotions, deductions, taxes, and operator-specific rules must be checked separately.
Can this calculation predict whether a bet will win?
No. It evaluates the entered numbers or settled score; it does not predict an event or provide a betting signal.
Why might my bookmaker show a different figure?
Differences can come from odds changes, currency rounding, push or void treatment, commission, bonus terms, or a different calculation convention.
