1. Copy the base
Find whether the multiple applies to the bonus or the deposit plus bonus.
2. Copy the rate
Use the contribution percentage for the game you will actually play.
3. Check the exits
Max bet, expiry, excluded games, and cashout caps can override the math.
This is a reading aid. Operators may add caps, expiry windows, max bets, excluded games, or other conditions that change the practical value.
What the result means
The calculator separates the headline bonus from the wagering base and the estimated turnover. That matters because an offer can be calculated against the bonus alone or against the deposit plus bonus, and games may contribute at different rates. The contribution check below the result shows how quickly the required play expands when your preferred game only counts for 10% — or counts for nothing.
What to copy from the terms
- Base: whether the multiple applies to the bonus or deposit plus bonus.
- Contribution: the percentage for the game you would actually play.
- Constraints: maximum bet, expiry, excluded games, and cashout clauses.
- Withdrawal: whether completing the rollover unlocks your full balance or only bonus-derived winnings.
Why a rollover number is not a value judgment
A lower turnover requirement is easier to complete, but it does not answer the other questions that decide whether the promotion is usable: how much the game costs in expected loss, whether the maximum bet makes the requirement unrealistic, how quickly the offer expires, and whether the operator has a reliable payout path. Use the number to compare the clause, not to declare a winner.

Does this tell me whether a bonus is good value?
No. It shows the turnover implied by the numbers you enter. Expiry, maximum bets, excluded games, cashout caps, and the operator’s withdrawal behavior still matter.
What if the operator uses a different contribution rate for each game?
Run the calculation using the rate for the game you expect to play, then check whether the terms use a separate cap or exclusion that changes the result.
