READ THE WRITTEN REQUIREMENT
What does a wagering multiplier mean?
Translate the requirement in the offer’s terms into a quantity. This calculation does not predict losses, winnings, eligibility or whether the bonus will become withdrawable.
Calculate the stated turnover
Qualifying turnover = stated basis × multiplier. At contribution c%, nominal turnover = qualifying turnover ÷ (c ÷ 100).
One multiplier can describe two very different totals.
For an illustrative deposit of 50 and bonus of 10, a 20× requirement on the bonus is 10 × 20 = 200. The same multiplier on deposit plus bonus is (50 + 10) × 20 = 1,200. The phrase “20×” alone leaves out the basis of the calculation.
If only 25% of nominal activity qualifies, $200 of qualifying turnover correspond arithmetically to $800 of nominal turnover. At 0% contribution, that activity makes no progress toward a positive requirement. Different contribution rates cannot be combined accurately in a single percentage without a breakdown.
Arithmetic does not replace the conditions.
Check the expiry date, eligible activity, maximum stake, balance order, maximum conversion and any withdrawal restrictions. The tool assumes a fixed contribution rate and no prior progress. It does not account for wins or losses or tell you how much money is needed to finish. If the terms are ambiguous, get an explanation from the operator before treating a calculated amount as actionable.
