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, science, and other fields.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or ending value
• Old Value — The original or starting value

Annualized Calculation: The total percentage increase is divided by the number of years to show the average annual growth rate.

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increases helps in understanding growth trends, comparing performance over time, and making informed decisions in business, investments, and research.

4. Using the Calculator

Tips: Enter the old (starting) value, new (current) value, and the number of years between measurements. All values must be positive numbers.

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 calculate percentage decrease?
A: The formula is the same - a decrease will simply show as a negative percentage increase.

Q3: Why annualize the percentage increase?
A: Annualizing allows comparison of growth rates over different time periods on a consistent yearly basis.

Q4: What if my old value was zero?
A: Percentage change from zero is undefined (division by zero), so the calculator requires positive values.

Q5: How accurate is the annualized percentage?
A: It assumes constant growth rate over time. For irregular growth patterns, more complex calculations may be needed.
