1. What is Percentage Increase?

Percentage increase is a measure of how much a quantity grows relative to its original size, expressed as a percentage of the original value. It's commonly used in finance, economics, and general mathematics to track growth or expansion.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

Example: If a product costs $100 and the price increases by 10%, the new price would be $100 × (1 + 10/100) = $110.

3. Practical Applications

Details: Percentage increase calculations are used in salary raises, price adjustments, investment growth, population growth studies, and performance improvements.

4. Using the Calculator

Tips: Enter the original value and the percentage increase you want to apply. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: How is percentage increase different from percentage points?
A: Percentage increase is relative to the original value, while percentage points are absolute differences between percentages.

Q2: Can I use this for decreasing values?
A: No, this calculator is for increases only. For decreases, use a percentage decrease calculator.

Q3: How do I calculate the percentage increase between two values?
A: Use the formula: ((New Value - Old Value) / Old Value) × 100.

Q4: Why does a 100% increase double the value?
A: Because 100% of the original value is added to itself, resulting in 2 × the original value.

Q5: How do compound percentage increases work?
A: For multiple increases, apply each percentage successively to the new value, not the original.
