1. What is Relative Increase?

Relative increase measures the percentage change between an old value and a new value. It shows how much a quantity has grown relative to its original size, expressed as a percentage.

2. How Does the Calculator Work?

The calculator uses the relative increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or initial value

Explanation: The formula calculates the difference between new and old values, divides by the old value to get the relative change, then multiplies by 100 to convert to percentage.

3. Importance of Relative Increase Calculation

Details: Relative increase is widely used in finance, economics, business analysis, and scientific research to measure growth rates, performance improvements, and changes over time.

4. Using the Calculator

Tips: Enter both old and new values. The old value cannot be zero. Results are expressed as a percentage, where positive values indicate increase and negative values indicate decrease.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between absolute and relative increase?
A: Absolute increase shows the actual difference (New - Old), while relative increase shows the percentage change relative to the original value.

Q2: Can relative increase be negative?
A: Yes, if the new value is smaller than the old value, the relative increase will be negative, indicating a 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 not possible.

Q4: How is this different from percentage change?
A: Relative increase and percentage change are essentially the same calculation, both expressing the change as a percentage of the original value.

Q5: Where is relative increase commonly used?
A: Commonly used in financial analysis (revenue growth), population studies, sales performance, and scientific experiments to measure changes.
