1. What is Percentage Increase?

Percentage increase calculates how much a value grows when increased by a certain percentage. It's commonly used in finance, economics, statistics, and everyday calculations like price increases or salary raises.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

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

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

3. Practical Applications

Details: This calculation is used in financial projections, retail pricing, salary negotiations, investment returns, and statistical analysis of growth rates.

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 this different from adding a percentage?
A: This method multiplies by (1 + rate/100), which is mathematically equivalent but emphasizes the proportional relationship.

Q2: Can I use this for percentage decreases?
A: Yes, by entering a negative percentage, though a dedicated percentage decrease calculator might be more intuitive.

Q3: What if I want to calculate the percentage change between two values?
A: You would need a different formula: ((New Value - Old Value) / Old Value) × 100.

Q4: How precise are the calculations?
A: Results are rounded to 2 decimal places for most practical applications.

Q5: Can I use this for compound percentage increases?
A: No, this calculates a single percentage increase. For compound increases, you would need to apply the formula multiple times.
