How Percentage Increase Works: Formula and Real-World Examples
Last updated: 2026-09-11 • Editorial Staff
Percentage increase measures the relative growth of a quantity from its initial value to a new, higher value.
Whether you are tracking salary increments, real estate appreciation, or quarterly business revenue growth, calculating percentage increase provides a standardized way to compare relative growth across different scales.
The Percentage Increase Formula
The percentage increase formula compares the net difference between the final value and initial value against the starting value:
Percentage Increase = [(Final Value - Initial Value) ÷ Initial Value] × 100
Step 1: Subtract the initial starting value from the final value to find the net absolute increase.
Step 2: Divide that increase by the initial starting value.
Step 3: Multiply the result by 100 to convert it into a percentage.
Real-World Example: Salary Increment
Suppose your annual salary increases from $50,000 to $60,000.
Absolute Increase = $60,000 - $50,000 = $10,000
Relative Growth = $10,000 ÷ $50,000 = 0.20
Percentage Increase = 0.20 × 100 = 20%
