1. What is Percentage Increase?

Percentage increase is a measure of 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 calculations.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• Old Value — The original amount before the increase
• Rate — The percentage increase (e.g., 5 for 5%)
• New Value — The resulting amount after the increase

Explanation: The formula multiplies the old value by 1 plus the rate expressed as a decimal (rate/100).

3. Practical Applications

Details: This calculation is used for price increases, salary raises, investment growth, population growth, and any scenario where values increase by a set percentage.

4. Using the Calculator

Tips: Enter the original value and the percentage increase. Both values must be non-negative numbers. The result shows the increased value.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from adding a percentage?
A: This formula increases the original value by a percentage of itself, while adding a percentage would simply add a fixed amount.

Q2: Can I use this for multiple percentage increases?
A: For consecutive increases, you would apply the formula sequentially to each percentage change.

Q3: What if I want to calculate the percentage increase between two values?
A: You would use: ((New Value - Old Value) / Old Value) × 100

Q4: Does the order of operations matter?
A: Yes, the percentage is always applied to the original value first in this calculation.

Q5: How do I calculate a decrease instead of an increase?
A: Use the same formula but with a negative percentage, or subtract the percentage from 100 first.
