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 in finance, economics, and various measurements.

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 relative change between two values by comparing the difference to the original value.

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 in the same units. The old value cannot be zero (division by zero is undefined). Negative values are allowed but may indicate percentage decrease.

5. Frequently Asked Questions (FAQ)

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

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

Q3: What if my old value was zero?
A: Percentage change from zero is undefined because you can't divide by zero. Consider using absolute change instead.

Q4: Can I use this for percentage decrease calculations?
A: Yes, the same formula works - you'll just get a negative result which indicates a decrease.

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