Percentage Increase Calculator

What is a Percentage Increase Calculator?

A percentage increase calculator helps you determine how much a value has grown from an original amount to a new amount. It answers questions like “What is the percentage increase from £50 to £65?” or “How much did my salary increase?”

The Percentage Increase Formula

Percentage Increase = ((New Value - Original Value) ÷ Original Value) × 100

Example

• Original: £50
• New: £65
• Increase: £65 - £50 = £15
• Percentage: (15 ÷ 50) × 100 = 30%

So £50 → £65 is a 30% increase.

How Our Calculator Works

1. Enter original value: The starting amount
2. Enter new value: The ending amount

Frequently Asked Questions

How do you calculate percentage increase?

Use the formula: ((New - Original) ÷ Original) × 100. For example, 50 to 65: ((65-50)÷50)×100 = 30%.

What if the result is negative?

A negative result means the value decreased, not increased. Use our Percentage Decrease Calculator for decreases.

Can I use this for any numbers?

Yes—prices, weights, scores, or any measurable quantity. The formula works the same.

What’s the difference between percentage increase and percentage point?

Percentage increase is relative change (e.g. 50 to 65 = 30% increase). Percentage point is absolute difference between two percentages (e.g. 10% to 15% = 5 percentage points).
