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 financial, scientific, and business contexts.

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.

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increases helps compare growth rates across different scales, track performance over time, and make data-driven decisions.

4. Using the Calculator

Tips: Enter both old and new values in the same units. The old value must be non-zero. Results show the percentage growth from old to new value.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I calculate annual percentage increase?
A: Use the same formula but ensure both values are separated by exactly one year. For multi-year periods, you may want to calculate compound annual growth rate (CAGR).

Q3: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than an increase.

Q4: Why is percentage increase useful in finance?
A: It allows comparison of growth rates between investments of different sizes and helps evaluate performance regardless of initial capital.

Q5: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
