1. What is Percentage Increase?

Percentage increase measures how much a quantity grows 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 to apply
• New Value — The resulting amount after the increase

Example: If an item costs \$100 and the price increases by 5%, the new price would be \$100 × (1 + 5/100) = \$105.

3. Practical Applications

Details: Percentage increase calculations are used in:

• Salary raises and wage increases
• Price adjustments and inflation calculations
• Investment growth projections
• Population growth estimates
• Performance improvements metrics

4. Using the Calculator

Tips:

• Enter the original value (must be ≥ 0)
• Enter the percentage increase rate (must be ≥ 0)
• The calculator will show the new increased value
• For percentage decreases, use a negative rate (in other calculators)

5. Frequently Asked Questions (FAQ)

Q1: How is percentage increase different from absolute increase?
A: Absolute increase shows the actual difference (New - Old), while percentage increase shows the relative change compared to the original value.

Q2: Can I calculate multiple percentage increases?
A: For consecutive increases, multiply the growth factors. For example, two 10% increases would be (1.10 × 1.10 = 1.21) or 21% total increase.

Q3: What if my percentage rate is more than 100%?
A: The calculator works the same way - a 150% increase would multiply the original value by 2.5 (1 + 150/100).

Q4: How do I reverse a percentage increase?
A: To find the original value before an increase, divide the new value by (1 + rate/100).

Q5: Why use percentage instead of absolute numbers?
A: Percentages allow comparison between different scales and sizes, making trends easier to understand regardless of the original amounts.
