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 rates, price changes, performance improvements, and other comparative metrics.

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 the new and old values, divides by the old value to get the relative change, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in business (sales growth, profit margins), finance (investment returns), science (experimental results), and everyday life (price comparisons). It provides a standardized way to compare changes across different scales.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined). Results are rounded to two decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What if my result is negative?
A: A negative result indicates a percentage decrease rather than increase. The absolute value shows the magnitude of change.

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

Q3: What's the maximum possible percentage increase?
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 does the old value need to be positive?
A: Division by zero is undefined, and negative values can lead to misleading percentage changes (e.g., from -1 to 1 would show as 200% increase).
