How to Use This Calculator
Enter the bonus credit size and your estimate of retention after playthrough (0–1). The tool multiplies them to show approximate expected cash value for forfeitable or sticky credits.
Credit size
Dollar amount of non-withdrawable bonus dollars you receive.
Retention rate
Your guess for what fraction survives wagering requirements and converts—use history from similar promos.
Read EV
Output is a rough dollar EV, not a guarantee.
Compare promos
Run scenarios for different retention assumptions before choosing which offer to grind.
Sticky Bonuses
Many sportsbook bonuses are sticky: you bet with them first, and only part converts to withdrawable cash after rollover. This heuristic multiplies credit by expected retention.
Examples
Example 1 — Defaults
Bonus $100, retention 0.75 → EV ≈ $75.
Example 2 — Pessimistic
$200 credit, 0.55 retention → $110 expected value.
Example 3 — Compare to free play
For SNR-style tokens use the free play value tool instead.
