Cost of living adjustment (COLA): what it means for pay

By the HRPricing editorial teamReviewed October 18, 2026How we research and score

COLA stands for cost of living adjustment: an increase in pay or benefits meant to offset inflation, not to reward performance. The best-known is Social Security's: benefits rise 3.6% starting with January 2027 payments, after 2.8% in January 2026, based on the CPI-W price index (SSA, checked October 18, 2026). No federal law makes private employers give one.

Cost of living adjustment (COLA): an increase in wages or benefits, usually a set percentage, intended to keep their buying power level as prices rise.

COLA vs a merit raise

A COLA in salary is an across-the-board increase: everyone covered gets the same percentage, often tied to a price index, whatever their performance. A merit raise is set person by person. Some employers fold both into one annual increase; union contracts and many public pay plans spell out a COLA formula.

A geographic cost of living differential is different again: pay set by where the employee lives, common on remote teams. It is a location adjustment, not an inflation one.

How the Social Security COLA is set

The Social Security COLA follows the change in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the prior year to the third quarter of the current year. The increase applies to December benefits, paid in January.

The Social Security wage base, which caps the 6.2% payroll tax, also rises: $184,500 in 2026 to $192,300 in 2027 (SSA). That changes employer payroll tax for high earners even with no raise. See 2026 payroll tax rates.

Example: what a 3.6% COLA costs an employer

3.6% COLA on a $55,000 salary
ItemBeforeAfter
Annual salary$55,000.00$56,980.00
Biweekly gross (26 checks)$2,115.38$2,191.54
Raise per year$1,980.00
Employer FICA on the raise (7.65%)$151.47
Total added cost per employee$2,131.47

HRPricing arithmetic, Oct 2026. FICA rates from IRS Publication 15 (2026). The $7,000 FUTA base and most state SUTA bases are below $55,000, so the raise adds no FUTA and, in most states, no SUTA.

For 10 employees at the same pay, that is $21,314.70 a year. Run your own numbers in the employee cost calculator or see what payroll costs in total.

How a COLA shows up on your paycheck

A COLA usually just raises your salary or hourly rate from its effective date, so gross pay goes up on the next check and the YTD totals mix old and new rates for the rest of the year. Taxes are withheld on the higher pay as normal. If your pay stub shows a separate COLA line, it is still taxable wages. For hourly staff, check that any COLA keeps pace with state rates in the 2026 minimum wage table.
