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, inflation, sales performance, investment returns, and population changes.

4. Using The Calculator

Tips: Enter the original (old) value and the new value. Both values must be positive numbers. The calculator will compute the percentage increase automatically.

5. Frequently Asked Questions (FAQ)

A: Percentage increase specifically measures growth, while percentage change can be positive (increase) or negative (decrease).

Q2: Can percentage increase be negative?
A: No, percentage increase specifically refers to growth. If new value is less than old value, it's a percentage decrease.

Q3: What if the old value is zero?

Q4: How is percentage increase used in business?
