Bonus Optimizer
A 420% match sounds huge — but a bonus is only worth what you can clear. Enter any deposit offer below and the calculator shows the real wagering, the expected cost to clear it at a given RTP, and whether the bonus is actually positive expected value. Defaults are set to LuckyAnon's 420% / 25x offer.
"Deposit + bonus" roughly doubles the real cost — 40x on deposit+bonus ≈ 80x of the bonus alone.
Positive expected value at these terms — this bonus is genuinely worth claiming.
Estimate only: EV = bonus − (total wagering × house edge). It ignores max-bet limits, game weighting, max-cashout caps and variance — real results swing widely. Use it to compare offers, not to predict a session.
We've already run the math on every major welcome offer — the biggest matches that actually hold up are in our deposit-bonus ranking.
18+ only. Gamble responsibly. This tool is an estimate to compare offers, not a prediction of results — gambling is negative expected value and carries real risk of loss. Support: US 1-800-GAMBLER · UK BeGambleAware.org.
