How Exactly to Calculate the Price Index?

In order to get accurate price index calculations, follow the steps below:

**Collect relevant pricing data.**The more competitors you want to compare, the more time you will have to spend on manual work, so make sure to use reliable monitoring tools. In some markets, prices should be monitored daily, otherwise you risk dealing with outdated prices or competitors that no longer exist.**Make a single spreadsheet with all the pricing data you collect.**It should be properly structured and easily available for you to operate it seamlessly.**Use formulas from the previous paragraphs.**Adding data gathered in your spreadsheet should not be a problem – you can fetch information from MS Excel in a few clicks.- This point is optional but it wouldn’t hurt to
**visualize the data**– you will be able to see market tendencies and compare competitors’ sales results. **Fetch all your sales data.**Analysis of price index would be useless without sales data because it tells you what market**impact your competitors have.****Find out what affected your sales.**Armed with all this information, you can figure out how price changes affected buyers' purchasing decisions.

Complexity of Calculation

At first glance, doing all the calculations using the above-mentioned formulas is an easy task. However, you should be prepared to run into some issues.

The major problem that you might face is data accuracy. Some companies make a mistake by getting information on marketplaces instead of from rival websites directly – these numbers may differ significantly.

Other eCommerce businesses use their own parsers or obtain pricing information manually. But since our concentration lasts up to a few hours, the risk of human error is pretty high. Irrelevant data can lead to wrong pricing decisions.

Even if you manage to achieve impeccable data quality, it’s only half the battle – you must also process and analyze the information. Human errors can occur when a person compares figures or tries to figure out a repricing strategy.

How to overcome this problem? Automation is the answer. Consider integrating repricing tools and price optimization software: it will track prices on competitor websites and marketplaces, analyze pricing history and provide recommendations on optimal price points. You can get real-time price index data by adding your formulas to a software dashboard – no manual calculations required.
