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.

You will also 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.
