Use this inflation calculator to determine how much prices have increased or decreased over time in the USA. Adjust for the Consumer Price Index (CPI) to understand the real value of money and plan for future price changes.
How to Use This Calculator
To calculate inflation in the USA, follow these steps:
- Enter the original price of an item in the "Original Price" field.
- Select the start year from the dropdown menu.
- Select the end year from the dropdown menu.
- Click the "Calculate" button to see the adjusted price.
The calculator will display the adjusted price based on the CPI data for the selected years. You can also view a chart showing the price changes over time.
How Inflation is Calculated
Inflation is calculated using the Consumer Price Index (CPI), which measures changes in the price of a basket of goods and services over time. The formula for calculating inflation is:
Inflation Rate = (CPIend - CPIstart) / CPIstart × 100
Where:
- CPIend = CPI for the end year
- CPIstart = CPI for the start year
The adjusted price is calculated using the following formula:
Adjusted Price = Original Price × (CPIend / CPIstart)
For example, if the original price of an item was $100 in 2010 and the CPI in 2010 was 200, and the CPI in 2020 was 250, the adjusted price would be:
Adjusted Price = $100 × (250 / 200) = $125
This means that the item would cost $125 in 2020 dollars to have the same purchasing power as it did in 2010.
Historical Inflation Data
The following table shows the historical CPI data for the USA from 1913 to 2023:
| Year | CPI | Inflation Rate |
|---|---|---|
| 1913 | 9.9 | N/A |
| 1929 | 17.2 | 73.7% |
| 1947 | 23.5 | 36.3% |
| 1960 | 30.2 | 28.6% |
| 1973 | 40.1 | 32.7% |
| 1981 | 82.4 | 105.4% |
| 1990 | 130.5 | 58.5% |
| 1999 | 173.1 | 32.9% |
| 2008 | 218.1 | 26.4% |
| 2018 | 246.1 | 13.0% |
| 2023 | 296.7 | 20.5% |
This data shows that prices in the USA have generally increased over time, with periods of higher inflation during economic downturns.
Future Inflation Projections
Projecting future inflation is challenging, but economists often use historical trends and economic indicators to make estimates. The following table shows projected CPI data for the USA from 2024 to 2030:
| Year | Projected CPI | Projected Inflation Rate |
|---|---|---|
| 2024 | 305.0 | 2.8% |
| 2025 | 310.5 | 1.8% |
| 2026 | 315.0 | 1.5% |
| 2027 | 318.5 | 1.2% |
| 2028 | 321.0 | 0.8% |
| 2029 | 323.0 | 0.6% |
| 2030 | 324.5 | 0.5% |
These projections suggest that inflation in the USA may continue to decline in the coming years, with rates below 2% by 2030.

- Inflation is calculated using the formula: Inflation Rate = (CPIend - CPIstart) / CPIstart × 100.
- What is the difference between inflation and deflation?
- Inflation occurs when the general price level of goods and services rises, while deflation occurs when the general price level falls.
- How does inflation affect savings and investments?
- Inflation can erode the purchasing power of savings and investments over time. To protect against inflation, investors often use inflation-adjusted instruments like TIPS (Treasury Inflation-Protected Securities).
