Percentage Increase Formula:
| From: | To: |
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 comparative metrics.
The calculator uses the percentage increase formula:
Where:
Explanation: The formula calculates the difference between new and old values, divides by the old value to get relative change, then converts to percentage by multiplying by 100.
Details: Percentage increase is fundamental in business (sales growth), finance (investment returns), science (experimental results), and everyday life (price changes). It provides a standardized way to compare growth across different scales.
Tips: Enter both new and old values as positive numbers. The old value cannot be zero (division by zero is undefined). Results show how much the value has increased as a percentage of the original value.
Q1: What if my result is negative?
A: A negative result indicates a percentage decrease rather than increase. The absolute value shows the percentage change.
Q2: How is this different from percentage difference?
A: Percentage increase compares to the original value only, while percentage difference compares two values relative to their average.
Q3: What's considered a "good" percentage increase?
A: This depends entirely on context - in investments, 7-10% annual return is good; in business, growth targets vary by industry.
Q4: Can I calculate percentage increase over multiple periods?
A: For compound growth, use the formula for each period sequentially or use the compound growth formula.
Q5: Why is the old value in the denominator?
A: This standardizes the increase relative to the starting point, allowing comparison between different scales.
