1. What Is The Index?

The Index is a statistical measure that calculates price or economic index relative to a base value. It expresses the current value as a percentage of the base value, providing a standardized way to compare changes over time or across different datasets.

2. How Does The Calculator Work?

The calculator uses the Index formula:

Where:

• \( Current\ Value \) — The present value being measured
• \( Base\ Value \) — The reference or starting value
• \( 100 \) — Scaling factor to express result as percentage

Explanation: The formula calculates how much the current value has changed relative to the base period, with 100 representing no change from the base.

3. Importance Of Index Calculation

Details: Index calculations are crucial for economic analysis, price comparisons, performance measurement, and tracking changes over time in various fields including finance, economics, and business analytics.

4. Using The Calculator

Tips: Enter both current value and base value in the same units. Values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What does an index value of 100 mean?
A: An index value of 100 indicates that the current value is exactly equal to the base value, representing no change from the reference period.

Q2: What is the difference between index and percentage change?
A: Index shows the relative position compared to base (100 = no change), while percentage change shows the difference from base (0% = no change).

Q3: When should I use index calculations?
A: Use for price indices, economic indicators, performance benchmarks, stock market indices, and any situation requiring standardized comparison to a base period.

Q4: Can index values be less than 100?
A: Yes, index values below 100 indicate that the current value is lower than the base value, representing a decrease from the reference period.

Q5: How do I interpret an index of 125?
A: An index of 125 means the current value is 25% higher than the base value, indicating growth or increase from the reference period.
