1. What is Percentage Increase?

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 or change.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or initial value

Explanation: The formula calculates the difference between new and old values, divides by the original value to get relative change, then multiplies by 100 to convert to percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is vital for understanding growth rates, comparing changes across different scales, financial analysis (like stock performance), and measuring improvements in business metrics.

4. Using the Calculator

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.

5. Frequently Asked Questions (FAQ)

Q1: What if my old value is zero?
A: Percentage increase is undefined when old value is zero, as you cannot divide by zero. In such cases, consider absolute difference instead.

Q2: How is percentage increase different from percentage points?
A: Percentage increase measures relative change from original value, while percentage points measure absolute difference between two percentages.

Q3: Can percentage increase be negative?
A: Yes, if new value is less than old value, the result is negative, indicating a percentage decrease rather than increase.

Q4: How is this different from percentage difference?
A: Percentage increase compares new value to original value. Percentage difference compares any two values relative to their average.

Q5: What are common applications of percentage increase?
A: Common uses include calculating salary raises, investment returns, price changes, population growth, and performance improvements.
