Bonus burn-down timer
Calculate true cost of meeting wagering requirements on welcome bonuses
Calculate the real expected loss while completing wagering requirements — and whether the bonus is worth it.
The wagering trap
A €50 welcome bonus with 10x wagering at 5% bookmaker margin means you must bet €500. At 5% margin, expected loss on €500 is €25. So the real bonus value is €50 − €25 = €25, not €50. This calculator does the math. Many wagering offers have ZERO real value (or negative). Sharper alternative: use Matched betting kit to extract bonus via lay-matching with negligible loss.

Example: classic welcome bonus
€50 bonus, 10x wagering, 5% margin bookmaker. Must bet €500. Expected loss: €500 × 0.05 = €25. Real bonus value: €50 − €25 = €25. At 5 bets per day at €20 each: 25 days to burn through. Compare: same offer at 8% margin bookmaker = €40 expected loss = €10 real value (barely worth it).
When to use
- Evaluating welcome bonus offers
- Comparing high-wagering vs low-wagering bonuses
