Formula
Percentage Increase = ((New Value - Original Value) / Original Value) × 100
Example 1: Salary increase from $50,000 to $55,000
Increase = ((55000 - 50000) / 50000) × 100
Increase = (5000 / 50000) × 100
Increase = +10%
The salary increased by 10%
Example 2: Sales growth from $100,000 to $125,000
Increase = ((125000 - 100000) / 100000) × 100
Increase = (25000 / 100000) × 100
Increase = +25%
Sales increased by 25%
Example 3: Double from 50 to 100
Increase = ((100 - 50) / 50) × 100
Increase = (50 / 50) × 100
Increase = +100%
The value doubled (100% increase)

Understanding Percentage Increase
Percentage increase measures how much a value has grown relative to its original amount. It's always calculated from the original (smaller) value to the new (larger) value.
- A 50% increase means the value grew by half of its original amount
- A 100% increase means the value doubled
- A 200% increase means the value tripled
- There's no maximum limit to percentage increase
Real-World Applications

Business: Your company's monthly revenue grew from $50,000 to $75,000. The 50% increase demonstrates strong business growth.
Investing: Your investment grew from $10,000 to $12,500. The 25% return helps you evaluate investment performance.
Tips for Best Results

Frequently Asked Questions
What if the new value is smaller than the original?
That would be a percentage decrease, not an increase. Use our Percentage Decrease Calculator for that scenario.
Can percentage increase exceed 100%?
Yes! A 100% increase means the value doubled. A 200% increase means it tripled. There's no upper limit.
How do I calculate the final value after a percent increase?
Add the increase amount to the original value. Or multiply the original value by (1 + percentage/100).
Is this the same as ROI (Return on Investment)?
Yes, percentage increase is often used to express ROI. If you invested $1,000 and it grew to $1,200, that's a 20% increase or 20% ROI.
How is this different from markup percentage?
They use the same formula! Markup percentage is essentially the percentage increase from cost to selling price.
