1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used to track growth in prices, salaries, investments, and other numerical values.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or starting value

Explanation: The formula calculates the difference between new and old values, divides by the old value to get relative change, then converts to percentage by multiplying by 100.

3. Practical Applications

Details: Percentage increase is used in finance (investment returns), economics (price changes), business (sales growth), and personal finance (salary increases).

4. Using the Calculator

Tips: Enter both old and new values. The old value must be greater than zero. The result shows how much the value has increased (or decreased if negative) as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What does 100% increase mean?
A: A 100% increase means the value has doubled (become twice as large as the original).

Q2: Can percentage increase be negative?
A: Yes, if the new value is smaller than the old value, the result will be negative, indicating a percentage decrease.

Q3: How is percentage increase different from percentage points?
A: Percentage increase measures relative change from an original value, while percentage points measure absolute differences between percentages.

Q4: What's the difference between percentage increase and compound growth?
A: Percentage increase measures simple one-time change, while compound growth accounts for growth on previously accumulated increases.

Q5: How do I calculate percentage increase over multiple periods?
A: For multiple periods, you would typically calculate compound annual growth rate (CAGR) rather than simple percentage increase.
