How this calculator works
To calculate percentage increase, subtract the original value from the new value, divide the difference by the original value, and multiply by 100. This shows the growth relative to where you started.
Formula: ((new value − original value) ÷ original value) × 100
Example
If a product price rises from 100 to 125:
((125 − 100) ÷ 100) × 100 = 25%
So the percentage increase is 25%.
Common uses

- Comparing revenue or sales over time
- Tracking increases in expenses or bills
- Checking how much an investment gained
