Percentage formulas
| Question | Formula | Example |
|---|---|---|
| X% of a number | X ÷ 100 × number | 15% of 200 = 30 |
| X is what % of Y | X ÷ Y × 100 | 45 of 50 = 90% |
| Percentage change | (new − old) ÷ old × 100 | 80 to 100 = +25% |
| Price after discount | price × (1 − discount ÷ 100) | 200 less 25% = 150 |
Example: your salary goes up from 8,000 to 8,600. The raise is (8,600 − 8,000) ÷ 8,000 × 100 = 7.5%.
