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 to analyze price changes, growth rates, and performance improvements.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Price — The current or increased value
• Old Price — The original or previous value

Explanation: The formula calculates the difference between new and old values, divides by the original value to get relative change, then converts to a percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increases helps in financial analysis, sales tracking, investment evaluation, and understanding inflation or price changes over time.

4. Using the Calculator

Tips: Enter both new and old prices in any currency (values must be positive). The old price cannot be zero as division by zero is undefined.

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 interpret a negative result?
A: A negative result indicates a percentage decrease rather than an increase.

Q3: What if the old price was zero?
A: The calculation is undefined when old price is zero, as you cannot divide by zero. This situation requires alternative analysis methods.

Q4: Can I use this for non-price calculations?
A: Yes, the formula works for any quantitative values where you want to measure relative growth (population, production, etc.).

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