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 changes over time.

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 original 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, price changes), business (sales growth), demography (population growth), science (experimental results), and many other fields to quantify change.

4. Using the Calculator

Tips: Enter both old and new values as positive numbers. The old value cannot be zero (division by zero is undefined). Results are rounded to 2 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What if the percentage is negative?
A: A negative result indicates a percentage decrease rather than 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 percentages.

Q3: Can I use this for very large numbers?
A: Yes, the calculator works for any positive numbers, but very large values may be hard to interpret meaningfully.

Q4: What's the maximum percentage increase possible?
A: There's no theoretical maximum. From zero to any positive value would be an infinite percentage increase.

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