Percentage Increase Formula:
| From: | To: |
Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used in finance, economics, business, and statistics to track growth and changes over time.
The calculator uses the percentage increase formula:
Where:
Explanation: The formula calculates the difference between new and old values, divides by the original value to get the relative change, then multiplies by 100 to convert to percentage.
Details: Percentage increase is essential for analyzing growth rates, performance metrics, investment returns, price changes, and business expansion. It provides a standardized way to compare changes across different scales and contexts.
Tips: Enter both new and old values as numerical values. The old value cannot be zero. Positive results indicate growth, negative results indicate decrease (though this calculator specifically calculates increase).
Q1: What's the difference between percentage increase and percentage change?
A: Percentage increase specifically measures growth, while percentage change can be positive (increase) or negative (decrease).
Q2: Can percentage increase be negative?
A: No, percentage increase specifically measures growth. If the result is negative, it indicates a percentage decrease.
Q3: What if the old value is zero?
A: The calculation is undefined when the old value is zero, as division by zero is mathematically impossible.
Q4: How is percentage increase used in real life?
A: Common applications include calculating salary increases, investment returns, sales growth, population changes, and price inflation.
Q5: What's a good percentage increase?
A: This depends on context. In business, higher is generally better, but expectations vary by industry and economic conditions.
