1. What is Rate of Increase?

The rate of increase measures the percentage change between an old value and a new value. It's commonly used in finance, economics, and data analysis to quantify growth or change over time.

2. How Does the Calculator Work?

The calculator uses the rate of increase formula:

Where:

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

Explanation: The formula calculates the percentage difference between the new and old values relative to the old value.

3. Importance of Rate Calculation

Details: Calculating rate of increase is essential for tracking growth, performance measurement, investment analysis, and understanding trends in various fields.

4. Using the Calculator

Tips: Enter both new and old values. The old value cannot be zero as division by zero is undefined. Values can be positive or negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative rate indicate?
A: A negative rate indicates a decrease rather than an increase between the old and new values.

Q2: Can I use this for percentage decrease?
A: Yes, when the result is negative, it represents a percentage decrease between values.

Q3: What if my 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 this different from percentage difference?
A: Rate of increase specifically measures change relative to the original value, while percentage difference can be calculated differently in various contexts.

Q5: Can I calculate compound growth with this?
A: This calculates simple percentage change. For compound growth over multiple periods, a different formula is needed.
