Formula: EV = Bonus - (Bonus × Wagering × (1 - RTP))

With a 100% bonus, 40× wagering, and 96% RTP:
EV = 100 - (100 × 40 × 0.04) = 100 - 160 = -$60

Understanding Bonus EV

Every casino bonus has hidden math. Here's what determines if it's worth your money.

What is Expected Value (EV)?

Expected Value is the average amount you can expect to win or lose on a bonus if you play it many times. A positive EV (+$20) means the bonus is mathematically profitable over time. A negative EV (-$60) means the casino has the edge.

Why Wagering Matters

Wagering requirements multiply the bonus amount by a factor (e.g. 40×). The higher the wagering, the more you expose to the house edge. A small wagering requirement can turn a losing bonus into a profitable one.

Game RTP Makes a Huge Difference

Slots typically have 94-96% RTP. Blackjack with basic strategy can be 99%+. The higher the RTP, the less the house edge, and the more valuable the bonus becomes.

The Break-Even Point

A bonus is +EV when: Wagering < 1 / (1 - RTP)
For slots (96%): wagering must be under 25× to be profitable.
For blackjack (99%): wagering can be up to 100× and still be +EV.

⚠️ Important Disclaimer: This calculator gives you the mathematical expected value based on ideal play (no mistakes, no variance). Real results vary significantly in the short term due to variance. A bonus showing -$60 EV doesn't guarantee you'll lose $60 — you might hit a big win early and come out ahead, or you might lose it all before completing wagering. Always gamble responsibly and only use money you can afford to lose.
