Enter bonus percentage, cap, wagering multiple and RTP. The result is an estimate, not a promise of winnings or processing time.
What a bonus is actually worth
A bonus is a loan you repay through turnover. Claim the cap and a wagering requirement of, say, 35x means the bonus amount must be staked 35 times before anything converts to withdrawable cash. Every one of those bets pays the house edge — the slice of each stake that RTP leaves out.
That gives the honest price of the offer: turnover times the house edge. If the expected cost is smaller than the bonus, the offer has positive expected value — on average, players finish ahead. If it is larger, the bonus is consumed by the edge before the wagering is met, and the headline number is marketing.
The break-even RTP is the tipping point: at a wagering multiplier w, the offer breaks even when the RTP reaches (1 − 1/w) × 100. At 35x that is 97.1% — higher than almost every slot. Which is, of course, the point of 35x.
