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 in finance, economics, statistics, and everyday life to track growth or expansion.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

Example: If a product's price increases from $50 (old value) to $75 (new value), the percentage increase is ((75-50)/50)*100 = 50%.

3. Practical Applications

Details: Percentage increase is used in salary raises, investment returns, price changes, population growth, performance improvements, and many other growth measurements.

4. Using the Calculator

Tips: Enter both 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)

Q4: Why is percentage increase important in business?
A: It allows comparison of growth rates across different scales (e.g., small vs. large companies).

A: Yes, values over 100% mean the quantity has more than doubled.
