How it works
Percentage change measures the difference between two values as a proportion of the original. The formula is:
(New Value − Original Value) ÷ Original Value × 100
For example, a salary that rises from £200 to £260 has changed by £60. £60 ÷ £200 × 100 = 30. This means the salary has gone up by 30 percent.
When to use this calculator
- Comparing prices over time
- Working out salary rises or cuts
- Analysing sales growth or drops
- Measuring changes in costs or bills
It handles both increases and decreases automatically, so you do not need to pick the right tool in advance.
