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 to track growth, inflation, price changes, and performance improvements.

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 relative change between two values by comparing the difference to the original value.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in business (sales growth), finance (investment returns), economics (inflation rates), and everyday life (price comparisons).

4. Using the Calculator

Tips: Enter both old and new values. The calculator will show both the absolute difference and the percentage increase. Old value must be non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What if the percentage is negative?
A: A negative result indicates a percentage decrease rather than an increase.

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute differences between percentages.

Q3: What's the maximum percentage increase possible?
A: There's no theoretical maximum. A value increasing from 1 to 2 is a 100% increase, from 1 to 3 is 200%, etc.

Q4: Can I calculate percentage decrease with this?
A: Yes, the result will simply be negative when the new value is smaller than the old value.

Q5: Why is the old value in the denominator?
A: This makes the increase relative to the starting point, allowing meaningful comparisons between different scales.
