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 value
• Old Value — The original or initial value

Explanation: The formula calculates the difference between the new and old values, divides by the old 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 crucial for understanding growth rates in business (revenue, profits), investments (stock prices, returns), population studies, and performance metrics.

4. Using the Calculator

Tips: Enter both new and old values. The old value cannot be zero (division by zero is undefined). Values can be positive or negative, but the calculation only makes sense when old value is non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What if the old value is zero?
A: The calculation is undefined when old value is zero, as you cannot divide by zero. In such cases, percentage increase cannot be calculated.

Q2: What does a negative percentage increase mean?
A: A negative result indicates a percentage decrease rather than increase (when new value is less than old value).

Q3: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between two percentages.

Q4: Can I use this for percentage change between any two values?
A: Yes, the same formula works for any percentage change calculation between two values.

Q5: How should I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice the original amount).
