Casino bonus calculator

Estimate the total stakes needed to meet a bonus wagering requirement, using the offer’s terms and your chosen game’s contribution rate.

Estimate the stakes needed

Enter the offer terms, an example deposit and the contribution rate for the game you plan to play. The result updates instantly; nothing is submitted or stored.

The deposit amount you want to use for this estimate.

The bonus percentage stated in the offer.

Enter this only if the offer caps the bonus amount.

The offer’s multiplier, such as 35×.

Choose the basis named in the offer terms; it changes the calculation.

Use the rate for your chosen game. A game with 0% contribution cannot clear the requirement.

How to read your result—and what it leaves out

Use the estimate to understand the play required, then check the offer terms it cannot assess.

What “estimated stakes needed” means

The main number is the total you would need to stake across wagers if every bet contributes at the rate you entered. It is not an amount to deposit at once and does not predict what you will lose. The coloured scale compares that estimate with the bonus funds; its labels are illustrative, not a verdict on the offer.

Bonus funds and wagering basis

The match percentage determines bonus funds, up to any maximum-bonus cap. Starting balance is your deposit plus those funds. The calculator then applies the multiplier to the amount named in the terms: bonus funds, the deposit, or both. This gives the qualifying wagering target before game contribution is taken into account.

35× bonus only$100 × 35 = $3,500

Based on a $100 deposit and a 100% match.

35× deposit + bonus$200 × 35 = $7,000

The same offer produces twice the target.

Game contribution changes the estimate

Contribution is the share of each stake that counts towards the target. At 20%, a $1 stake counts as $0.20, so estimated total stakes are five times the 100%-contribution figure. A game with 0% contribution cannot reduce the requirement.

Use the rate for the game you intend to play. The result panel’s “How this is calculated” section shows the steps for your figures; our wagering requirements guide has more examples.

What the estimate cannot assess

Even a correct stakes estimate cannot tell you whether a bonus is good value, whether every bet will qualify, or whether a withdrawal will be approved. Check maximum-bet rules, excluded games, expiry periods, maximum cashout and eligibility conditions in the operator’s current terms.

These terms can make a smaller, clearer promotion more practical than a larger advertised bonus. Our casino bonus listings show the details available when each bonus was checked. Do not deposit more just to reach a bonus limit.
