Bonus Wagering Calculator

See the practical side of a casino bonus before opting in. Enter the headline offer and its terms to estimate the bonus value, rollover target, and how game contribution changes the amount you need to stake.

Your offer terms

Use the terms shown by the casino. This calculator is an estimate, not a replacement for the offer's full conditions.

For example, a game with 10% contribution needs ten times as much stake to clear the same target.

How the maths works

First we calculate the bonus by applying the percentage to your deposit, then applying any maximum-bonus cap. The wagering target is the stated multiplier applied either to the deposit or to the deposit plus bonus, depending on the terms.

Game contribution matters because not every game counts equally. A £100 rollover target at 20% contribution requires £500 of play on that game to make the full £100 of progress.

Terms worth checking

  • Whether the multiplier applies to the bonus, deposit, or both.
  • Maximum bet limits while an offer is active.
  • Which games contribute fully, partially, or not at all.
  • Expiry dates, withdrawal caps, and payment exclusions.

Bonus wagering calculator FAQs

What does 35x wagering mean?

It means the relevant balance must be staked 35 times before the bonus conditions are completed. If the rule applies to a £20 deposit plus a £20 bonus, the target is £40 multiplied by 35, or £1,400.

Why is the required stake higher for some games?

Casinos may count different game categories at different rates. A game at 10% contribution only adds £1 of wagering progress for every £10 staked, so it takes more play to reach the same target.

Does this calculator tell me whether a bonus is good?

No. It gives the turnover estimate. The value of an offer also depends on its game restrictions, time limit, maximum bet, withdrawal rules, and your own budget.
