Bonus Expected Value (EV) Calculator 2026
Don't be fooled by big numbers. Enter deposit, bonus, wagering, game contribution, and RTP to see the real expected profit.
🎲 Calculate Real Bonus Value
📉 Why Nominal Bonuses Are Misleading
A $1000 bonus sounds incredible, but high wagering requirements (e.g., 50x) and low game contribution can turn it into a net loss. Our calculator reveals the true expected value – the average profit you can expect after completing all requirements. Positive EV means the bonus is statistically profitable; negative means you're likely to lose money even after the bonus.
The Formula:
EV = Bonus Amount - (Total Wagering × House Edge × Game Contribution Factor)
Where: House Edge = (100% – RTP%). Total Wagering = (Deposit + Bonus) × Wagering Multiplier.

❓ Frequently Asked Questions
What is Expected Value (EV) of a casino bonus?
Expected value (EV) is the average profit you can expect from a bonus after completing wagering requirements. Positive EV means the bonus is profitable on average.
Why is the nominal bonus amount misleading?
A $1000 bonus sounds great, but if wagering requirements are high, your actual expected value may be negative. Our calculator reveals the true value.
What is game contribution %?
Game contribution % determines how much of your wager counts toward bonus wagering. Slots usually count 100%, while table games may count 10-20%.
What RTP should I use?
Use the RTP of the game you plan to play. For slots, 96-98% is common. For blackjack, 99.5% with basic strategy.
Can the EV be negative and still be worth claiming?
Negative EV bonuses can still be worthwhile if you value the entertainment or if you are close to earning loyalty rewards.
