Understanding Percentage Increase

Percentage increase shows how much a value has grown relative to its original amount. The formula used is:

Percentage Increase = ((Final Value - Initial Value) / Initial Value) × 100

For example, if a product price increases from £50 to £65, the absolute increase is £15, and the percentage increase is 30%.

Common Uses

• Calculating price increases and inflation rates
• Tracking business growth and revenue changes
• Measuring population growth
• Analyzing investment returns
• Comparing salary increases
• Monitoring website traffic growth

Note

If the final value is less than the initial value, you'll see a negative percentage, which indicates a percentage decrease rather than an increase. The initial value cannot be zero as division by zero is undefined.
