An index number is basically a ratio which has the involvement of more than two periods. For every index number, the base year remains the same. Some of the examples are CPI, WPI, BSE, etc. An index number is generally of two types: simple and composite.

Using index numbers to forecast results This shows us the effect of inflation over time, as this can be expected to increase prices. As prices are expected to rise over time it can mean that comparing revenues or costs at different points in time is a bit meaningless.

An index value of 100 indicates that a result exactly matches the baseline average, an index of 200 that the result is twice the average, and an index of 50 that it is half the average. Broadly speaking, an index of less than 90 or more than 110 would be considered different enough from the average to take note of.

An index number is a method of evaluating variations in a variable or group of variables in regards to geographical location, time, and other features. The base value of the index number is usually 100, which indicates price, date, level of production, and more. There are various kinds of index numbers.

“An index number is a statistical measure, designed to measure changes in a variable, or a group of related variables”. “Index number is a single ratio (or a percentage) which measures the combined change of several variables between two different times, places or situations”.

Index numbers provide a simple way of representing changes over time. Each value is expressed as a percentage of a base value which is the value that occurred in a base period. The index numbers below show how average earnings in different sectors changed between 2000 and 2006.

The aggregative method is commonly used to calculate the price index. In this method, the index number (P) = the sum of all the values of all the commodities in the current year (P1) divided by the sum of all the values of the same commodities in the base year (P0) and multiplied by 100.

An index number is used to measure changes in prices paid for raw materials; numbers of employees and customers, annual income and profits, etc. If the index number is used to measure the relative change in just one variable, such as hourly wages in manufacturing, it is referred to as a simple index.
