Percent Increase Formula:
| From: | To: |
Percent increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to compare growth rates, price changes, performance improvements, and other relative changes between two values.
The calculator uses the percent increase formula:
Where:
Explanation: The formula calculates the relative change between two percentages by finding the difference, dividing by the original value, and converting to a percentage.
Details: Calculating percent increase is essential in business (sales growth), finance (investment returns), statistics (data analysis), and everyday life (price comparisons). It provides a standardized way to compare changes regardless of the original scale.
Tips: Enter both percentages in the input fields. The old percentage cannot be zero (division by zero is undefined). Results are shown with two decimal places for precision.
Q1: What's the difference between percent increase and percentage points?
A: Percent increase shows relative change, while percentage points show absolute difference. A change from 10% to 15% is a 50% increase (5/10) but only 5 percentage points.
Q2: Can percent increase be negative?
A: Yes, if the new percentage is less than the old percentage, the result will be negative, indicating a percent decrease.
Q3: How is this different from simple difference?
A: Simple difference (new - old) shows absolute change, while percent increase shows relative change compared to the original value.
Q4: What if my old percentage is zero?
A: The calculation is undefined when old percentage is zero, as you cannot divide by zero. Consider using absolute difference instead.
Q5: How should I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
