1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to analyze cost changes, price increases, growth rates, and performance improvements.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Cost — The current or increased value
• Old Cost — The original or baseline value

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

3. Importance of Percentage Increase Calculation

Details: Percentage increase is crucial for financial analysis, budgeting, pricing strategies, performance evaluation, and understanding inflation or growth rates in various contexts.

4. Using the Calculator

Tips: Enter both new and old costs in the same currency. The old cost must be greater than zero. Results show the percentage by which the new cost exceeds the old cost.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage mean?
A: A negative result indicates a percentage decrease rather than an increase.

Q2: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between two percentages.

Q3: Can I use this for non-financial calculations?
A: Yes, the formula works for any measurable quantity (weights, distances, etc.) not just monetary values.

Q4: What if my old value was zero?
A: The calculation is undefined when dividing by zero. You cannot calculate percentage increase from zero.

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