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 in finance, economics, statistics, and everyday life to track growth or change.

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 value to get relative change, then converts to percentage by multiplying by 100.

3. Practical Applications

Details: Percentage increase is used for:

• Calculating salary raises or price increases
• Measuring investment growth
• Analyzing sales performance
• Tracking population growth
• Comparing statistical data over time

4. Using the Calculator

Tips:

• Enter both values in the same units
• Old value cannot be zero (would cause division by zero)
• Negative results indicate percentage decrease
• Works with any numerical values (prices, quantities, measurements)

5. Frequently Asked Questions (FAQ)

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

Q2: How do I interpret a negative percentage increase?
A: A negative result actually indicates a percentage decrease between the values.

Q3: Why can't the old value be zero?
A: Division by zero is mathematically undefined. You cannot calculate percentage change from zero.

Q4: 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.

Q5: Can I use this for exponential growth calculations?
A: For exponential growth, you'd typically use logarithmic transformations or compound growth formulas instead.
