Percentages, multipliers and percentage points
Bonus pages use percentages and x multipliers for several unrelated quantities. Keeping the units attached prevents simple arithmetic errors from becoming mistaken conclusions about value or risk.

Translate each symbol
A 50% match means one half of an eligible deposit. A 5x requirement means five times a defined amount. A 20% contribution means one fifth of an eligible stake counts to a counter. These values cannot be compared directly because they describe different relationships.
Distinguish points from relative change
Moving a hypothetical contribution from 20% to 25% is an increase of five percentage points. Relative to the original 20%, it is a 25% increase. Both statements can be mathematically correct, but they communicate different magnitudes. Always identify the starting figure.
Keep the practical consequence visible
A lower multiplier can still produce a larger target if the bonus amount is larger. A higher match percentage can still produce a smaller reward if its cap is lower. Avoid judging an offer from one percentage without the accompanying pounds, limits and conditions.
| Bonus amount | Multiplier | Target |
|---|---|---|
| £5 | 10x | £50 |
| £20 | 5x | £100 |
Attach a sentence to every number
A number becomes easier to interpret when it is written as a complete relationship: this reward is fifty percent of this eligible deposit, or this wager contributes twenty percent of its stake to this counter. That sentence exposes the base. It also prevents a percentage attached to one component from being applied to the whole account. When comparing changes, state both the old and new figures. A movement from 5x to 4x is one fewer multiple and a twenty-percent reduction in the multiplier; it is not a one-percent reduction. The resulting target still depends on the bonus amount. These distinctions are basic arithmetic, but promotional pages often compress them into symbols that can be misread quickly.
Keep currency consistent too. A pound amount and a euro amount cannot be compared by their printed numbers alone. This library uses pounds for teaching examples so the percentage arithmetic remains transparent.
- Write the base quantity next to every percentage or multiplier before comparing two offers or calculating a target.
- Distinguish a change in percentage points from a relative percentage change when discussing contribution or match rates.
- Check whether a cap or eligibility threshold interrupts an otherwise simple proportional relationship.
Worked example · hypothetical
Two target sizes
A £5 bonus at 10x has a £50 target. A £20 bonus at 5x has a £100 target. The smaller multiplier does not produce the smaller target because the base is four times larger. This arithmetic does not recommend either promotion.

Common questions
Is 10x the same as 10%?
No. Ten times is multiplication by ten. Ten percent is multiplication by 0.10. Confusing them changes a result by a factor of one hundred.
Are the figures an offer or a promise?
No. They are hypothetical teaching figures. They explain definitions and calculations without recommending an operator, a deposit, a game or a strategy.
