1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage of the original value. 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 Number — The current or final value
• Old Number — The original or initial value

Explanation: The formula calculates the difference between the new and old numbers, divides by the old number 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 financial analysis (stock growth, inflation), business metrics (sales growth), scientific research (experimental results), and everyday life (price comparisons).

4. Using the Calculator

Tips: Enter both old and new numbers. The old number cannot be zero (division by zero is undefined). Numbers can be positive or negative, whole numbers or decimals.

5. Frequently Asked Questions (FAQ)

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

Q2: How is this different from percentage difference?
A: Percentage increase compares a new value to an original value, while percentage difference compares any two values without directionality.

Q3: What's the maximum possible percentage increase?
A: There's no theoretical maximum. Going from 0.0001 to 100 would be a 999,999,900% increase.

Q4: How do I calculate percentage increase over multiple periods?
A: For compound growth, use the formula: (Final Value / Initial Value)^(1/Periods) - 1

Q5: Why is percentage increase often more meaningful than absolute increase?
A: Percentage increase provides context relative to the starting point, making comparisons more meaningful across different scales.
