Percentage Increase Formula:
From: | To: |
Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday life to track growth rates.
The calculator uses the percentage increase formula:
Where:
Explanation: The formula calculates the difference between new and old values, divides by the old value to get the relative change, then multiplies by 100 to convert to a percentage.
Details: Percentage increase is essential for analyzing growth rates, comparing changes over time, evaluating investment returns, measuring performance improvements, and making data-driven decisions.
Tips: Enter both new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Values can be integers or decimals.
Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is the simple difference (New - Old), while percentage increase shows the change relative to the original value.
Q2: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than an increase.
Q3: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
Q4: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible from a zero base.
Q5: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.
