Wagering calculator: work out a bonus playthrough

How the calculator works

The wagering requirement is the calculation base multiplied by the multiplier. With a 20 bonus and 35× wagering, the requirement is 20 × 35 = 700.

Game contribution is the share of each bet that counts. At 50%, the amount you need to wager doubles: 700 requires 1,400 in bets.

The number of bets is the amount to wager divided by your bet size. 1,400 at 1 per spin means 1,400 spins.

Three worked examples

Bonus only: a 50 bonus with 35× wagering means 50 × 35 = 1,750 to wager. At 0.50 per spin that is 3,500 spins.

Deposit + bonus: the same terms on a 100 deposit and a 100 bonus give (100 + 100) × 35 = 7,000 – twice as much as when only the bonus counts. Always check which base the offer uses.

Free spin winnings: if 100 free spins leave a bonus balance of 12 and the requirement is 45×, you need to wager 12 × 45 = 540. At 0.20 per spin that is 2,700 spins.

Game contribution in practice

Contribution decides how much of each bet counts. If a game counts 20%, a 1,750 requirement means 1,750 ÷ 0.20 = 8,750 in bets. Set the calculator to the contribution of the game you actually plan to play, as stated in the bonus terms.

What the calculator does not tell you

The result is the amount you must bet, not a forecast. It cannot tell whether your balance will last: that depends on volatility and luck. It also helps to keep the theoretical cost in mind. With 96% RTP, wagering 1,750 has an expected cost of about 1,750 × 4% = 70 – more than the 50 bonus in the first example.

Check the other limits in the terms alongside the result: the maximum bet while wagering, the deadline, excluded games and any maximum cashout. A bet above the limit can void the bonus even if the turnover is complete.
