Bonus value calculator

Explore how a bonus amount and wagering multiplier interact with an RTP assumption you supply. The result illustrates a simplified calculation; it does not establish what a bonus is worth or whether to claim it.

The bonus funds you'll receive.

How many times the bonus must be wagered.

The most you're allowed to withdraw from the bonus. Leave blank if there's no cap.

Enter the RTP you want to assume. Check the specific game rules for its stated RTP; no default is supplied.

Enter a bonus amount, wagering and an RTP assumption to see illustrative arithmetic.

Illustrative arithmetic only. The model assumes full bonus-only wagering at the RTP you enter and 100% game contribution. It ignores variance, running out of funds, deposit wagering, bet limits and expiry. Applying a cashout cap to this number does not calculate an expected withdrawal. A positive result does not mean you will profit; you can lose your entire stake. 21+, please play responsibly.

How the estimate is calculated

We work out the playthrough (bonus × wagering), then apply the house edge implied by the game's RTP (1 − RTP) to that turnover to approximate what the required betting is expected to cost. The bonus minus that expected cost is the illustrative balance. If you enter a cashout cap, the displayed number is limited to that cap. This shortcut does not model the distribution of outcomes or calculate the expected payout.
