Last month, U.S. residents spent an average of $99 a day, according to a report released by Gallup in which Americans were asked how much they spent "yesterday" in restaurants, gas stations, stores or online – not counting home, vehicle or other major purchases, or normal monthly bills.

Gallup staffer Rebecca Riffkin reports that the $99 average is similar to December 2014’s $98 average, as December spending is usually the highest of any month each year, although the highest estimate for any month in Gallup's trend is $114 from May 2008.

Monthly spending averages in 2015 hovered near $90 for most of the year, with January ($81) and February ($82) significantly lower and December ($99) significantly higher than the other months. The average across all months in 2015 -- $89 -- is essentially the same as the 2014 annual average of $90, but much higher than averages of between $64 and $72 from 2009 to 2012.

The December 2015 average is based on interviews with more than 13,000 U.S. adults.
