1. What is Percent Increase?

Percent 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 measurements.

2. How Does the Calculator Work?

The calculator uses the percent increase formula:

Where:

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

Explanation: The formula calculates the relative difference between two values as a percentage of the original value.

3. Importance of Percent Increase Calculation

Details: Percent increase is widely used in finance (investment returns), economics (inflation rates), business (sales growth), science (experimental results), and everyday life (price comparisons).

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The calculator will show the percentage increase (positive result) or decrease (negative result).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percent increase and absolute increase?
A: Absolute increase is the simple difference (New - Old), while percent increase shows this difference relative to the original value.

Q2: Can percent increase be more than 100%?
A: Yes, this indicates the new value is more than double the original value.

Q3: How do I calculate percent decrease?
A: The same formula works - you'll get a negative result when the new value is smaller than the old value.

Q4: What if my old value is zero?
A: The calculation is undefined (division by zero). You can only calculate percent increase from a non-zero baseline.

Q5: How is percent increase different from percentage points?
A: Percentage points measure absolute difference between percentages, while percent increase measures relative change from an original value.
