Consumer spending in the U.S. rose in January even as incomes dropped by the most in 20 years, showing households were weathering the payroll-tax increase by socking away less money in the bank.

Household purchases, which account for about 70 percent of the economy, climbed 0.2 percent after a 0.1 percent gain the prior month, a Commerce Department report showed today in Washington. The median estimate in a Bloomberg survey of 76 economists called for a 0.2 percent advance. Incomes slumped 3.6 percent, sending the saving rate down to the lowest level since November 2007.

Employment gains, the rebound in housing and growing demand for autos will probably keep supporting consumer spending in the first quarter as the world’s largest economy picks up from an end-of-year slowdown. Even so, rising gasoline prices and the need to rebuild nest eggs may make it difficult for households to match last quarter’s performance.

“It’s going to be touch and go for the consumer for the next few months,” said Ryan Sweet, a senior economist at Moody’s Analytics in West Chester, Pennsylvania, who correctly projected the 3.6 percent drop in income. “The consumer is going to be able to support the recovery, but they’re not going to be able to take it” to a higher level, he said.

Stocks Drop

Stock-index futures held earlier losses after the report. The contract on the Standard & Poor’s 500 Index maturing this month dropped 0.5 percent to 1,506.3 at 9:17 a.m. in New York.

Projections for spending ranged from a drop of 0.2 percent to a 0.4 percent gain.

The Bloomberg survey median called for incomes to fall 2.4 percent.

The slump in incomes in January was the biggest since January 1993 and followed a 2.6 percent jump in December. Some companies paid dividends and employee bonuses earlier than usual before tax rates went up this year, removing a gain usually seen in January. The Commerce Department estimated the January level of wages was reduced by about $15 billion and December was boosted by about $30 billion, reflecting the timing of the bonuses.

The saving rate dropped to 2.4 percent from 6.4 percent.
