U.S. inflation rate in 2024: 2.97%


Inflation in 2024 and its effect on dollar value

$1 in 2023 is equivalent in purchasing power to about $1.03 today. The dollar had an average inflation rate of 2.97% in the last 12 months. As a result, the real value of a dollar has been decreasing recently. Purchasing power decreased by 2.97% in 2024 compared to 2023. On average, you would have to spend 2.97% more money in 2024 than in 2023 for the same item.

This means that today's prices are 1.03 times as high as average prices since 2023, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 97.087% of what it could buy back then.

The inflation rate in 2023 was 4.12%. The current inflation rate compared to the end of last year is now 2.97%. If this number holds, $1 today will be equivalent in buying power to $1.03 next year. The current inflation rate page gives more detail on the latest inflation rates.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 2024 is 314.18. It was 304.70 in the previous year, 2023. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2023 to 2024 (figures shown are purchasing power equivalents of $1):

Dallas-Fort Worth, Texas experienced the highest rate of inflation during the 1 years between 2023 and 2024 (3.70%).

San Diego, California experienced the lowest rate of inflation during the 1 years between 2023 and 2024 (0.00%).

Note that some locations showing 0% inflation may have not yet reported latest data.

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 2023 would be equivalent to £1.04 in 2024, an absolute change of £0.04 and a cumulative change of 3.90%.

In Canada, CA$1.00 in 2023 would be equivalent to CA$1.01 in 2024, an absolute change of CA$0.01 and a cumulative change of 1.15%.

Compare these numbers to the US's overall absolute change of $0.03 and total percent change of 3.11%.

Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

Between 2023 and 2024:

This chart shows the average rate of inflation for select CPI categories between 2023 and 2024.

Compare these values to the overall average of 2.97% per year:

CategoryAvg Inflation (%)Total Inflation (%)$1 in 2023 → 2024
Food and beverages1.681.681.02

For all these visualizations, it's important to note that not all categories may have been tracked since 2023. This table and charts use the earliest available data for each category.

How to calculate inflation rate for $1 since 2023

Our calculations use the following inflation rate formula to calculate the change in value between 2023 and today:

CPI today CPI in 2023
2023 USD value
Today's value

Then plug in historical CPI values. The U.S. CPI was 304.70216666667 in the year 2023 and 314.175 in 2024:


$1 in 2023 has the same "purchasing power" or "buying power" as $1.03 in 2024.

To get the total inflation rate for the 1 years between 2023 and 2024, we use the following formula:

CPI in 2024 - CPI in 2023CPI in 2023
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

314.175 - 304.70216666667304.70216666667

Alternate Measurements of Inflation

There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.

Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.

Personal Consumption Expenditures (PCE) Inflation

The PCE Price Index is the U.S. Federal Reserve's preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.

The PCE Price Index changed by 1.90% per year on average between 2023 and 2024. The total PCE inflation between these dates was 1.90%. In 2023, PCE inflation was 3.74%.

This means that the PCE Index equates $1 in 2023 with $1.02 in 2024, a difference of $0.02. Compare this to the standard CPI measurement, which equates $1 with $1.03. The PCE measured -1.21% inflation compared to standard CPI.

For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.

Core Inflation

Also of note is the Core CPI, which uses the standard CPI but omits the more volatile categories of food and energy.

Core inflation averaged 2.78% per year between 2023 and 2024 (vs all-CPI inflation of 2.97%), for an inflation total of 2.78%. In 2023, core inflation was 4.78%.

When using the core inflation measurement, $1 in 2023 is equivalent in buying power to $1.03 in 2024, a difference of $0.03. Recall that the converted amount is $1.03 when all items including food and energy are measured.

Chained Inflation

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 2.34% per year between 2023 and 2024, a total inflation amount of 2.34%.

According to the Chained CPI measurement, $1 in 2023 is equal in buying power to $1.02 in 2024, a difference of $0.02 (versus a converted amount of $1.03/change of $0.03 for All Items).

In 2023, chained inflation was 3.94%.

Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 2023, our investment would be nominally worth approximately $1.42 in 2024. This is a return on investment of 42.12%, with an absolute return of $0.42 on top of the original $1.

These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.

The compounding effect of inflation would account for 3.02% of returns ($0.04) during this period. This means the inflation-adjusted real return of our $1 investment is $0.38. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 2023 to latest available data for 2024 using average monthly close price.

Price index data from 1774 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society. Price index data from 1634 to 1773 is from the American Antiquarian Society, using British pound equivalents.
