How to use the bonus wagering calculator
Every bonus comes with a wagering requirement: the amount you must stake before the bonus can be withdrawn. The wagering calculator turns that rule into plain numbers, so you can see the real size of the job before you accept an offer.
How wagering is calculated
The basic formula is bonus × multiplier. Some terms apply the multiplier to (deposit + bonus) instead, so check the wording. Enter the bonus, the multiplier, the game’s RTP and your stake. The calculator then shows the total wagering, the expected cost, the expected value, the spins you need and roughly how long that takes at about 600 spins an hour. Presets come from live offers, so you can load a real one in a click.
A worked example
Take a £100 bonus with 35× wagering on a slot with 96.5% RTP.
- Wagering: £100 × 35 = £3,500.
- Expected cost: £3,500 × 3.5% (that is 1 − 0.965) = £122.50.
- Expected value: £100 − £122.50 = −£22.50.
- Spins at a £1 stake: 3,500, or about 5.8 hours at 600 spins an hour.
If the same terms applied to deposit plus bonus (£100 + £100), the wagering would double to £7,000, the expected cost to £245, and the expected value would fall to −£145. That is why the small print matters more than the headline number.
Which games suit clearing wagering
The calculator lists top games for the job: higher RTP and lower volatility, because they tend to swing less while you work through the requirement. Check the terms first, as some games count for less than 100% or are excluded. You can browse top high-RTP slots or low-volatility slots to build a shortlist.
These are averages over a very long run, not a forecast. Any single bonus can finish above or below the expected value. Use the result to decide whether an offer is worth your time, and only play with money you can afford to lose. Wagering-free deals skip this maths altogether, so see wagering-free bonuses if you prefer simple terms. For a wider verdict, try the bonus value calculator. Players must be 18+.
Questions people ask
How do I calculate wagering requirements?
Multiply the bonus by the wagering multiplier. A £100 bonus at 35× means £3,500 of total stakes. Some offers apply the multiplier to deposit plus bonus, which doubles the figure in this case. Divide the total by your stake to see how many spins that is. The wagering calculator does it for you.
What does 35x wagering mean?
It means you must stake 35 times the bonus amount before you can withdraw winnings linked to it. On a £50 bonus that is £1,750 in total bets. It is not a target to win, only an amount to play through. Higher multipliers mean more spins and a higher expected cost.
Which slots are top for clearing wagering?
Slots with a high RTP and lower volatility are usually the top fit, because the expected cost per £1 staked is smaller and the swings are gentler. Always check which games count towards wagering and the maximum stake allowed. The calculator lists suitable games, and you can also use Ask in plain English.
How long does it take to clear a bonus?
Divide total wagering by your stake to get spins, then divide by about 600 spins an hour. £3,500 at a £1 stake is 3,500 spins, roughly 5.8 hours. A £2 stake halves that. Take breaks and set a time limit before you start.
Do wagering requirements apply to winnings from free spins?
Often yes. Many free spins offers apply a multiplier to the winnings, and some apply it to the bonus balance. The terms will say which. You can model this with the free spins value calculator. Check the multiplier and any withdrawal cap before you claim, and remember these are averages rather than promises.
