Where:

• New — The current or final value
• Old — The original or initial value

Explanation: The difference between new and old values is divided by the old value, then multiplied by 100 to convert to a percentage.

3. Importance of Percentage Increase Calculation

Q2: How do I interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).

Q3: Why can't the old value be zero?
A: Mathematically, division by zero is undefined, making percentage change calculations impossible.

Q4: What's the difference between percentage increase and percentage points?
A: Percentage increase is relative to the original value, while percentage points are absolute differences between percentages.

Q5: How accurate is this calculator?
A: It provides precise calculations based on your inputs, rounded to 2 decimal places.
