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 track growth, inflation, performance improvements, and other changes over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final amount
• Old Value — The original or starting amount

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

3. Importance of Percentage Increase

Details: Percentage increase is widely used in business (sales growth), finance (investment returns), economics (inflation rates), and personal finance (salary increases). It provides a standardized way to compare growth across different scales.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The calculator will show how much the value has increased as a percentage of the original amount.

5. Frequently Asked Questions (FAQ)

Q1: What if my old value was zero?
A: The calculation is undefined when the old value is zero, as you cannot divide by zero. The calculator requires positive values.

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

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

Q4: Can I use this for percentage decrease?
A: Yes, the result will automatically show a negative percentage when the new value is smaller than the old value.

Q5: How precise are the results?
A: Results are rounded to two decimal places for readability while maintaining reasonable precision.
