Percentage Increase Formula:
From: | To: |
Definition: This calculator determines the percentage increase between two values, showing how much a value has grown relative to its original amount.
Purpose: It helps analyze growth rates in financial, statistical, scientific, and everyday calculations.
The calculator uses the formula:
Where:
Explanation: The difference between new and old values is divided by the old value to get relative change, then multiplied by 100 to convert to percentage.
Details: This calculation is fundamental for understanding growth rates, price changes, performance improvements, and statistical analysis.
Tips: Enter both new and old values (must be positive numbers). The old value cannot be zero as division by zero is undefined.
Q1: What does a negative result mean?
A: A negative percentage indicates a decrease rather than an increase between the values.
Q2: How do I interpret a 100% increase?
A: A 100% increase means the new value is exactly double the old value.
Q3: Why can't the old value be zero?
A: Division by zero is mathematically undefined, making percentage change calculations impossible.
Q4: Can I use this for percentage decrease?
A: Yes, the same formula works - a negative result indicates a percentage decrease.
Q5: 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.
