Revenues of the US population in April 2015 increased by 0.4% compared with the previous month, according to the Ministry of Commerce.
Analysts surveyed by Bloomberg, expected a rate growth of 0.3%.
Meanwhile, the spending of Americans last month have not changed since the March level, while experts predicted growth of 0.2%.
The PCE Core index (Personal Consumption Expenditures, Excluding Food & Energy), which is considered by the Federal Reserve System in the assessment of the risks of inflation, in April rose 0.1% and 1.2% in annual terms. Analysts had forecast an increase of the first indicator by 0.2%, and the second - by 1.4%.
Savings rate in April rose to 5.6% from 5.2% in March. The salaries and wages increase by 0.2% in monthly terms.
Analysts point out that Americans prefer not to spend the saved money as a result of lower fuel prices, and to use them for the payment of debts and increase savings. For a more active growth of spending, which accounts for about 70% of US GDP, there is the need for a more significant increase in wages in the country, experts say.
"The costs grow poorly in the second quarter - said a senior economist at Moody's Analytics - Ryan Sweet. - After such indicators for April, forecasts of many experts in the quarter as a whole now seem too optimistic. Things in the labor market in general are good, but the salary is growing too slowly".
