Bonus Value Calculator
Version 1.2 · Last updated 2026-07-12
Work out what a casino bonus is really worth — deposit match, no-deposit, cashback, or sticky/phantom — once you factor in the wagering requirement, game contribution and cashout cap. Same formula behind our Bonus Value Score, fully published. Free, instant, no signup.
Enter a bonus amount and wagering requirement to see the score.
How this is calculated
We estimate the stakes you'll actually have to wager (adjusted for game contribution), the expected loss to the house edge while doing so, and the bonus value after any cashout cap — then check whether it's realistic to clear before it expires. The result is normalized to a 0-100 score. Full methodology: How we rate.
This tool gives an estimate for comparison purposes based on the numbers you enter — always confirm the exact terms with the operator before opting in to a bonus.
Note on sticky/phantom bonuses: because the bonus principal is clawed back at cashout, its average (expected-value) score is usually low or near zero even when the headline amount looks generous — its real upside, if any, comes from variance-seeking play strategies that a simple expected-value calculator like this one can't model. Treat a low sticky score as accurate for the "average outcome," not as a claim that no player could ever come out ahead. New to this? Read sticky vs non-sticky bonuses explained.
Frequently asked questions
What is a good bonus value score?
The score runs from 0 to 100, where higher means more of the headline amount survives the terms. As a rough guide, offers scoring above about 60 tend to have fair wagering and few traps, 30–60 are middling, and below 30 the terms erode most of the value. It's a comparison tool between offers, not a guarantee of profit — the house edge means the expected return on any bonus is still negative.
Is a 100% deposit match always a good bonus?
No. The headline match percentage says almost nothing about real value. A 100% match with 45× wagering, a low max cashout and a short expiry can be worth far less than a smaller 50% match with 20× wagering. That's exactly why this calculator scores the terms rather than the headline.
Why does a sticky bonus score so low?
With a sticky (non-withdrawable) bonus the principal is clawed back when you cash out, so on an average, expected-value basis very little of it reaches your balance — which is what this calculator measures. A low sticky score is accurate for the typical outcome; any upside comes from high-variance play a simple model can't capture. See sticky vs non-sticky bonuses.
