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, inflation, performance improvements, and other comparative metrics.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final measurement
• Old Value — The original or initial measurement

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is fundamental in business (sales growth), finance (investment returns), economics (inflation rates), and science (experimental results). It provides standardized comparison regardless of original scale.

4. Using the Calculator

Tips: Enter both old and new values. The old value must be non-zero. Results show percentage increase (positive) or decrease (negative).

5. Frequently Asked Questions (FAQ)

Q1: What if my old value is zero?
A: Percentage change is undefined when dividing by zero. The calculator requires a non-zero old value.

Q2: How is this different from percentage points?
A: Percentage increase measures relative change, while percentage points measure absolute difference between percentages.

Q3: Can the result be negative?
A: Yes, if new value is less than old value, it indicates a percentage decrease.

Q4: What's the difference between percentage increase and growth factor?
A: Growth factor is (new/old), while percentage increase is ((new-old)/old)×100.

Q5: How should I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
