1. What is Percentage Increase?

Percentage increase measures the relative growth from an original value to a new value, expressed as a percentage. It's commonly used to analyze changes in prices, salaries, populations, and other quantitative data over time.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• \( New \) — The new or current value
• \( Old \) — The original or previous value

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.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is essential for financial analysis, business planning, economic studies, and personal finance management. It helps track growth rates, inflation, investment returns, and performance metrics.

4. Using the Calculator

Tips: Enter the original value and new value in the same units. Ensure the old value is greater than zero to avoid division by zero errors. The result shows the percentage change from old to new value.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage increase mean?
A: A negative percentage increase indicates a decrease or reduction from the original value to the new value.

Q2: How is percentage increase different from percentage points?
A: Percentage increase measures relative change, while percentage points measure absolute difference between two percentages.

Q3: Can I use this for year-over-year growth calculations?
A: Yes, this calculator is perfect for calculating annual growth rates, inflation rates, and other time-based comparisons.

Q4: What if my old value is zero?
A: The calculation requires division by the old value, so old value must be greater than zero to avoid mathematical errors.

Q5: How accurate is the percentage increase calculation?
A: The calculation is mathematically precise. Accuracy depends on the accuracy of your input values and proper unit consistency.
