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 resulting amount after increase

Example: If a $100 product has a 10% price increase, the new price is $100 × 1.10 = $110.

3. Practical Applications

Details: This calculation is used for salary raises, price adjustments, investment growth, statistical analysis, and any scenario where values increase by percentages.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How is this different from adding a percentage?
A: It's mathematically equivalent - multiplying by (1 + rate/100) is the same as adding (old value × rate/100) to the old value.

Q2: Can I use this for percentage decreases?
A: Yes, by entering a negative percentage (though this calculator requires positive values - you would need to modify the formula).

Q3: What if I want to calculate multiple increases?
A: For sequential increases, apply the formula repeatedly. A 10% increase followed by 20% would be (old × 1.10 × 1.20).

Q4: How precise are the calculations?
A: Results are rounded to 2 decimal places. For financial calculations, consider using exact decimal arithmetic.

Q5: Can this be used for compound growth?
A: For compound growth over multiple periods, you would need a compound interest formula instead.
