1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used in finance, economics, and data analysis to track growth and changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

Explanation: The formula calculates the relative change between two values and expresses it as a percentage of the original value.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for analyzing growth rates, comparing performance metrics, tracking price changes, and making informed decisions based on quantitative changes over time.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero to avoid division by zero errors.

5. Frequently Asked Questions (FAQ)

Q1: What if the result is negative?
A: A negative result indicates a percentage decrease rather than an increase, meaning the value has decreased from the original amount.

Q2: Can I use this for percentage decrease calculations?
A: Yes, the same formula works for both increase and decrease. A negative result indicates a decrease.

Q3: What are some practical applications?
A: Useful for calculating salary increases, price changes, population growth, investment returns, and performance improvements.

Q4: How is this different from percentage points?
A: Percentage increase measures relative change, while percentage points measure absolute difference between two percentages.

Q5: What if the old value is zero?
A: The calculation is undefined when the old value is zero, as division by zero is mathematically impossible.
