Percentage Increase Formula:
From: | To: |
Definition: This calculator determines the percentage increase between two values (new and old).
Purpose: It helps analyze growth rates, price changes, performance improvements, and other comparative measurements.
The calculator uses the formula:
Where:
Explanation: The difference between new and old values is divided by the old value to get the relative change, then multiplied by 100 to convert to a percentage.
Details: Percentage increase is fundamental in financial analysis, sales reporting, scientific experiments, and performance metrics to understand growth or change over time.
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 is this different from percentage difference?
A: Percentage increase specifically measures growth from an original value, while percentage difference compares two values without reference to which is original.
Q3: What's considered a good percentage increase?
A: This depends entirely on context - a 5% sales increase might be excellent for one business but poor for another.
Q4: Can I use this for percentage decrease calculations?
A: Yes, when the new value is smaller than the old, the calculator will show a negative percentage (decrease).
Q5: Why is the old value required to be positive?
A: The calculation requires division by the old value, which must be non-zero. Negative values could produce misleading results.
