Percentage Increase Formula:
| From: | To: |
Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to analyze growth rates in financial, statistical, and scientific data.
The calculator uses the percentage increase formula:
Where:
Explanation: The formula calculates the difference between two numbers, divides by the original number, and converts to a percentage by multiplying by 100.
Details: Percentage increase is vital for understanding growth trends in business revenue, investment returns, population changes, scientific measurements, and many other fields where relative change matters more than absolute change.
Tips: Enter both values (Number1 and Number2) as positive numbers. Number1 should be the initial/original value, and Number2 should be the final/new value.
Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase shows the numerical difference (Number2 - Number1), while percentage increase shows the relative change compared to the original value.
Q2: Can percentage increase be negative?
A: Yes, if Number2 is less than Number1, the result will be negative, indicating a percentage decrease rather than increase.
Q3: How is percentage increase different from percentage points?
A: Percentage increase measures relative change from an original value, while percentage points measure absolute differences between percentages (e.g., 5% to 7% is a 2 percentage point increase, but a 40% increase).
Q4: What are common applications of percentage increase?
A: Common uses include calculating investment returns, price changes, salary increases, population growth rates, and performance improvements.
Q5: How do I interpret a percentage increase over multiple years?
A: For multi-year comparisons, you might want to calculate compound annual growth rate (CAGR) rather than simple percentage increase to account for compounding effects.
