Monthly US Inflation Rate 1913 to Present

The following table presents the monthly inflation rate, i.e. the rate of increase (or decrease) in the basket of goods and services tracked by the U.S. Bureau of Labor Statistics over the last month.

Typically when we talk about inflation we are talking about the change in prices (price inflation) on a yearly or annual basis, i.e. how much prices have changed since last year. 

This table presents the inflation data on a monthly basis (i.e. how much prices have changed since last month).

Although these are the components of the Annual inflation rate, since inflation compounds, the annual inflation rate is not just adding the monthly inflation rates. But looking at the monthly rates can give you some perspective on how the Annual rate is going. Often you will have the occasional month that is negative (deflation) that chips away at the overall annual inflation but it is much rarer to have enough monthly deflation to actually result in annual deflation.

Monthly Inflation Chart 2019-2022

In the following chart you can see how monthly inflation for 2022 (red bars) and 2021(pink bars) compares with 2020 (medium blue bars) and 2019 (light green bars). We can see that January's massive red line was double even 2021's pink line and February's red line was well above 2021's pink line.

Monthly inflation is often zero or negative in the 4th Quarter, but 2021's entire 4th quarter was much higher than average. October's monthly inflation was a massive 0.83%, compared to 0.04% in October 2020. November 2021 was 0.49% compared to -0.06% in 2020.

At 0.84% (January), 0.91%(February), and 1.34% (March) monthly inflation was high even for the first quarter of a year when monthly inflation is already at its highest. Typically monthly inflation from January through May, is in the 0.30% to 0.50% range. And then, in June, inflation typically starts to moderate into a lower range, and then by October through December monthly inflation is typically very low or even negative. But, as we can see from the table above, 2021 was consistently above that range and 2022 so far has been even higher. April was the first month in 2022 where the 2022 line was actually lower than 2021.

Note that January 2022's 0.84% was the highest January since 1990.

Monthly Inflation 2019-2022

In the complete table below, you may notice things like the fact that the last quarter of the year is more likely to have deflation while the first quarter is more likely to be highly inflationary.

See How Do I Calculate the Inflation Rate? for more information on calculating inflation.
See: annual inflation rates for what is normally considered "the Inflation Rate".

This data is based on the historical CPI-U data from the Bureau of Labor Statistics. Typically monthly inflation is a fraction of a percent although when inflation is particularly bad it can be a whole percentage point or more. During Hyperinflation it can be 10% or even hundreds of percent. But hyperinflationary rates are not sustainable in the long run and usually result in a massive chaos.
