Wagering requirement calculator
Wagering terms are easy to misread. This calculator turns a bonus offer into two plain numbers: how much you must bet in total before the bonus can be withdrawn, and about how many bets that takes at your usual stake.
Calculator
- Wagering base
- 100
- Total turnover required
- 3,500
- Approximate number of bets
- 3,500
The turnover needed is not a chance of finishing it: every bet carries a house edge.
Enter the bonus amount, your deposit, the wagering multiple, whether the wagering applies to the bonus only or to bonus plus deposit, the contribution of the game you plan to play, and your average bet. Nothing you type is stored or sent anywhere.
What it calculates
The total turnover is the wagering multiple times the wagering base, divided by the game contribution. The base is the bonus alone or the bonus plus the deposit, depending on the offer's terms. The number of bets is the turnover divided by your average bet, rounded up.
Contribution is the share of each bet that counts toward the requirement. A game that counts 100% moves the requirement by the full bet. A game that counts 10% needs ten times as much betting.
Worked example
Take a 100 EUR bonus with a 100 EUR deposit and 35x wagering. This is an example, not a real offer.
| Wagering base | Contribution | Turnover required | Bets at 1 EUR |
|---|---|---|---|
| Bonus only (100 EUR) | 100% | 3,500 EUR | 3,500 |
| Bonus + deposit (200 EUR) | 100% | 7,000 EUR | 7,000 |
| Bonus only (100 EUR) | 10% | 35,000 EUR | 35,000 |
The same headline multiple can mean very different workloads. That is why we read the base and the contribution before the number itself.
What the result does not tell you
The calculator shows the turnover needed, not the chance of finishing it. Betting is a cost: every bet has a house edge, so completing a large requirement usually means paying part of that cost, and your balance may run out first.
Also check the maximum bet allowed while a bonus is active, the maximum cashout, the expiry period and any excluded games. These can change the real value of an offer, and the calculator does not include them.
Frequently asked questions
What does 35x wagering mean?
You must place bets totaling 35 times the wagering base before the bonus funds can be withdrawn. With a 100 EUR base that is 3,500 EUR in bets.
Do I count the deposit in the wagering base?
Only if the terms say so. Some offers apply wagering to the bonus alone, others to bonus plus deposit, which roughly doubles the work for a matched bonus.
Why does the game I play change the result?
Casinos assign each game a contribution percentage. Slots often count 100%, while table games and live games often count less or nothing, so the same requirement takes far more betting on them.
