The calculation, in plain sight
Bonus basis × multiplier = qualifying turnover. Divide the target by the contribution percentage expressed as a decimal to get cumulative eligible stakes at that single rate.
Example: £20 × 10 = £200. At 20% contribution, £200 ÷ 0.20 = £1,000 in actual stakes. This is a mechanical illustration, not an estimate of money you need to deposit or a recommendation to stake it.
What the result cannot tell you
The tool assumes the same contribution rate throughout. It does not model wins, losses, eligible games, a maximum stake, balance depletion, expiry or cancellation. A zero contribution means no progress and is rejected. A zero multiplier produces zero turnover, but other conditions can still apply.
Amounts shown are in pounds for readability. Values are calculated in your browser and are not stored or sent to a server. Results are rounded for display. Privacy details.
