1. What is Percentage Increase?

Percentage increase measures the relative growth or change from an original value to a new value, expressed as a percentage. It helps quantify how much something has grown compared to its original state.

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 starting value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is widely used in finance, economics, business analysis, statistics, and everyday life to measure growth rates, price changes, performance improvements, and other comparative analyses.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value must be greater than zero. The result shows the percentage increase (positive for growth) or decrease (negative for reduction).

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative percentage increase indicates a percentage decrease, meaning the new value is smaller than the old value.

Q2: How is percentage increase different from percentage points?
A: Percentage increase measures relative change, while percentage points measure absolute difference between two percentages.

Q3: Can percentage increase exceed 100%?
A: Yes, percentage increase can exceed 100% when the new value is more than double the old value.

Q4: What if the old value is zero?
A: Percentage increase is undefined when the old value is zero, as division by zero is mathematically impossible.

Q5: How is percentage increase used in real-world applications?
A: It's used for calculating salary increases, investment returns, sales growth, population changes, and any situation where relative growth measurement is needed.
