# How to Adjust for Inflation in Excel: A Step-by-Step Guide

Adjusting for inflation in Excel is simpler than you might think. By using a few straightforward formulas, you can accurately account for the changing value of money over time. This involves using the Consumer Price Index (CPI) to adjust historical financial data to present-day values.

## How to Adjust for Inflation in Excel

This section will guide you through the steps to adjust for inflation using Excel. By the end, you’ll be able to convert past dollar amounts into present values, giving you a clearer picture of economic changes over time.

### Step 1: Gather CPI Data

First, find historical CPI data for the time periods you are interested in.

You can usually get this information from government websites or financial databases. Download or copy this data into an Excel spreadsheet.

### Step 2: Enter CPI Data in Excel

Make sure to label each column with the appropriate year and corresponding CPI value. This will make it easier to reference these values in your formulas later.

### Step 3: Prepare Your Data

Identify the dollar amount and year you want to adjust for inflation.

Enter this data into your spreadsheet. Label these cells clearly so you can easily reference them in your formula.

### Step 4: Use the Inflation Adjustment Formula

Apply the inflation adjustment formula: Adjusted Amount = Original Amount * (Current Year CPI / Original Year CPI).

Enter this formula into a new cell. Replace "Original Amount," "Current Year CPI," and "Original Year CPI" with the appropriate cell references from your spreadsheet.

### Step 5: Review and Verify

Check your calculations to ensure they are correct.

Cross-reference with other sources if necessary to verify the accuracy of your inflation adjustments.

After completing these steps, you will have adjusted your financial data for inflation, making it more accurate and useful for analysis.
