To calculate the nominal price index, you need to follow these steps:
1. Select a base year: Determine the year you will use as the base year for comparison. This year is typically designated as 100 in the index.
2. Select a basket of goods: Choose a representative basket of goods or a selection of prices that will be used to calculate the index. This basket should cover commonly consumed goods and services.
3. Determine the prices: Collect the prices of the chosen goods and services for both the base year and the desired year(s) in consideration.
4. Calculate the index for each year: Divide the price of each item in the desired year by its corresponding price in the base year. Multiply the result by 100 to express it as a percentage. Repeat this calculation for each item.
5. Weight the prices: If different items in the basket have varying importance or represent different proportions of expenditure, assign weights to each item based on their relative importance or expenditure shares. Multiply each price ratio by its respective weight.
6. Sum up the weighted price ratios: Add up the weighted price ratios calculated in the previous step.
7. Calculate the index: Divide the sum obtained in the previous step by the sum of the weights.
8. Express the index: Multiply the result obtained in the previous step by 100 to express the nominal price index as a percentage.
This index will provide an overall measure of the change in prices from the base year to the desired year(s).
