1. What Is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It quantifies how much a value has grown compared to its original amount.

2. How Does The Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New \) — New value after increase
• \( Old \) — Original value before increase

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 percentage.

3. Importance Of Percentage Increase Calculation

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

4. Using The Calculator

Tips: Enter the original (old) value and the new value. Both values must be positive numbers, with the old value greater than zero to avoid division by zero errors.

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 original value.

Q2: How is percentage increase different from percentage points?
A: Percentage increase measures relative change from original value, 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 original value.

Q4: What if the old value is zero?
A: Percentage increase cannot be calculated when the old value is zero, as it would involve division by zero, which is mathematically undefined.

Q5: How is percentage increase used in real-world applications?
A: Common applications include calculating salary raises, investment returns, sales growth, population increases, and price inflation rates.
