• Percentage = 10%
• Calculation: 60 × (1 + 10/100) = 60 × 1.10 = £66

5. Frequently Asked Questions (FAQ)

A: Percentage increase is relative to the original value, while percentage points are absolute differences between percentages.

Q3: How do I reverse a percentage increase?
A: To find the original value after an increase, divide the new value by (1 + percentage/100).

Q4: Why does 10% increase of £60 equal £66?
A: Because 10% of 60 is 6, so the increased value is 60 + 6 = 66.

Q5: Is this calculator suitable for compound percentage increases?
A: No, this calculates a single percentage increase. For compound growth over multiple periods, you'd need a different formula.
