WASHINGTON (October 14, 2012)--Social Security recipients shouldn't expect a big increase in monthly benefits come January.

Preliminary figures show the increase will be between 1 percent and 2 percent, which will be among the lowest since automatic adjustments were adopted in 1975

The raise will be made official Tuesday, when the government releases inflation figures for September.

The cost-of-living adjustment is tied to a government measure of inflation adopted by Congress in the 1970s,which shows that consumer prices have gone up by less than 2 percent in the past year.

Monthly benefits for retired workers average $1,237, meaning the typical retiree can expect a raise of between $12 and $24 a month.

This year, Social Security recipients got 3.6 percent increase in benefits.

That came after two years with no increase.
