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 financial growth, price changes, and performance improvements.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New \) — The current or new value
• \( Old \) — The original or old value

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

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increase is essential for financial analysis, investment decisions, price monitoring, and performance tracking in business and economics.

4. Using the Calculator

Tips: Enter both old and new values in the same currency units. The calculator works for any positive values (prices, quantities, measurements, etc.).

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: Can the result be negative?
A: Yes, if the new value is smaller than the old value, it indicates a percentage decrease rather than increase.

Q3: 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.

Q4: What if my old value is zero?
A: The calculation is undefined (division by zero). Percentage change can't be calculated when starting from zero.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise when using exact input values. Rounding may occur in presentation of results.
