Return in Bonus ROI — is the percentage return a player can expect when attempting to clear a casino bonus. It weighs bonus value against expected losses from wagering (house edge/RTP), game contribution, and rules. This gambling term helps you compare casino promotions and decide whether clearing a bonus is profitable, neutral, or not worth the risk.
Understanding Return in Bonus ROI
In gambling, Return in Bonus ROI meaning is the expected percentage gain or loss from trying to clear a casino bonus. A practical Return in Bonus ROI definition is: (expected value after wagering ÷ effective cost—usually your deposit or total turnover) × 100. It matters because wagering requirements, RTP, game contribution, and volatility can turn a big-looking offer into poor value.

Examples of Return in Bonus ROI
Common ways Return in Bonus ROI shows up in play:
- High WR example: 100% up to $200, WR 40× bonus (=$8,000 turnover). On 96% slots, expected loss ≈ 4% of $8,000 = $320; bonus value $200 → EV = −$120 → ROI negative.
- Favorable game choice: 98% RTP, low-variance slot that contributes 100% improves stability and expected ROI versus a 94% high-variance slot.
- Contribution rules: Slots 100%, blackjack 10% contribution. Moving play to blackjack drags ROI because you must wager 10× more to meet WR.
- Stacking value: Reload + cashback + free spins can lift ROI from negative to breakeven or positive if terms and contributions align.
