But much of the higher spending likely reflects greater use of electricity and other utilities; spending on goods actually fell.
The Commerce Department said that consumer spending rose 0.2 percent last month, an improvement from April's reading of no change.
Analysts expected spending to edge up only 0.1 percent, according to a survey by Thomson Reuters.
Incomes rose by 0.4 percent, slightly less than expected. They were boosted by the temporary hiring of census workers.
The savings rate - or the percentage of income that wasn't spent - rose to 4 percent, the second straight increase.
