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, business metrics, and scientific 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 difference between values, divides by the original to get relative change, then converts to percentage by multiplying by 100.

3. Practical Applications

Details: Percentage increase is used in:

• Financial analysis (revenue growth, investment returns)
• Business metrics (sales growth, customer acquisition)
• Scientific research (population growth, experimental results)
• Personal finance (salary increases, expense tracking)

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero (division by zero is undefined).

5. Frequently Asked Questions (FAQ)

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

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

Q3: What if my old value was zero?
A: Percentage change is undefined when starting from zero, as it would require division by zero.

Q4: 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.

Q5: Can I calculate compound growth with this?
A: For compound growth over multiple periods, you would need to calculate each period's growth separately or use a compound growth formula.
