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 analyze 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 measurement
• Old Value — The original or initial measurement

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

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increases is fundamental in financial analysis, business growth measurement, scientific research, and performance tracking across many fields.

4. Using the Calculator

Tips: Enter both new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is simply new minus old value, while percentage increase shows the change relative to the original value.

Q2: How do I interpret negative percentage results?
A: A negative result indicates a percentage decrease rather than increase.

Q3: Can I use this for annual growth rate calculations?
A: Yes, when comparing annual metrics (e.g., this year's revenue vs last year's).

Q4: What if my old value was zero?
A: Percentage change is undefined when starting from zero. Consider using absolute difference instead.

Q5: How precise are the calculations?
A: Results are precise to two decimal places, suitable for most applications.
