How to Use This Inflation Calculator
This tool helps you adjust project budgets for inflation by calculating how the value of money changes over time. Here’s how to use it:
- Enter the original amount of money from your project budget
- Select the year this amount is from (starting year)
- Select the year you want to adjust to (target year)
- Optionally, enter a custom annual inflation rate if you don’t want to use historical CPI data

The calculator uses official Consumer Price Index (CPI) data from the U.S. Bureau of Labor Statistics to provide accurate inflation adjustments for project budgeting.
Frequently Asked Questions
What is an inflation adjustment calculator?
+
An inflation adjustment calculator is a tool that helps you determine the current value of a past monetary amount by accounting for inflation. It allows you to adjust historical prices or costs to reflect their present-day equivalents, providing a more accurate representation of purchasing power over time. This is especially important for long-term project budgeting :cite[1].
Why is it important to adjust project budgets for inflation?
+
Adjusting for inflation is crucial because the value of money changes over time due to economic factors. A dollar today does not have the same purchasing power as a dollar from several years ago. By adjusting for inflation, you can accurately compare monetary values across different time periods and make informed financial decisions for your projects :cite[1]:cite[3].
What inflation data does this calculator use?
+
By default, the calculator uses the Consumer Price Index (CPI-U) data from the U.S. Bureau of Labor Statistics, which measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. This is the most widely used measure of inflation. You can also enter a custom inflation rate if you prefer :cite[10].
How accurate are inflation adjustment calculations?
+
While inflation adjustment calculators provide a reasonable estimate, they may not account for specific factors that could influence the actual purchasing power of money, such as regional variations, changes in consumer habits, or the availability of substitute goods or services. For critical financial decisions, consider consulting with a financial professional :cite[1]:cite[5].
Can I use this for future inflation projections?
+
Yes, you can use this calculator to estimate future values by selecting a future target year. For future projections, you’ll need to enter an estimated annual inflation rate, as historical CPI data won’t be available for future years. Many financial planners use an average long-term inflation rate of around 3% for projections :cite[5]:cite[6].
