1. What is Percent Increase?

Percent increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used in finance, economics, statistics, and everyday life to quantify growth or change.

2. How Does the Calculator Work?

The calculator uses the percent increase formula:

Where:

• \( New \) — The new or current value
• \( Old \) — The original or previous value

Explanation: The formula calculates the difference between the 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 Percent Increase Calculation

Details: Percent increase is crucial for analyzing growth rates, price changes, performance improvements, investment returns, and many other quantitative comparisons in business and research.

4. Using the Calculator

Tips: Enter both old and new values. The old value cannot be zero. Values can be positive or negative, but typically represent measurable quantities.

5. Frequently Asked Questions (FAQ)

Q1: What if the result is negative?
A: A negative result indicates a percent decrease rather than increase, meaning the value has gone down.

Q2: Can I use this for percentage change between any two values?
A: Yes, this formula works for any quantitative comparison between two values where the original value is not zero.

Q3: How is percent increase different from percentage points?
A: Percent increase measures relative change from an original value, while percentage points measure absolute difference between two percentages.

Q4: What are some common applications of percent increase?
A: Common uses include calculating price inflation, salary raises, population growth, investment returns, and performance improvements.

Q5: How should I interpret a 100% increase?
A: A 100% increase means the value has doubled - the new value is twice the original value.
