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, performance improvements, and other changes over time.

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 starting value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance (investment returns, price changes), business (sales growth), science (experimental results), and everyday life (salary increases, inflation tracking).

4. Using the Calculator

Tips: Enter the original (old) value and the new value. Both values must be positive numbers, with old value greater than zero. The calculator will show the percentage increase (or decrease if negative).

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than an increase.

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

Q3: What's the maximum possible percentage increase?
A: There's no upper limit. If old value approaches zero, percentage increase can become extremely large.

Q4: Can I use this for percentage decrease calculations?
A: Yes, the same formula works. A decrease will show as a negative percentage increase.

Q5: Why is the old value required to be greater than zero?
A: Division by zero is undefined mathematically. If old value is zero, percentage change cannot be calculated.
