Every fall, two announcements roll out within weeks of each other: the federal pay raise for current employees and the cost-of-living adjustment (COLA) for federal retirees. Because both numbers get reported as a single percentage tied to “federal benefits,” it’s easy to assume they’re the same adjustment applied twice — once before retirement, once after.
But they’re determined differently, triggered by different data, and influenced by different parts of the government. Understanding the difference matters most in years when the two numbers move apart, since that gap can catch retirees off guard if they expected their annuity to track pay the way it did while they were working.
Two Adjustments, Two Very Different Purposes
The federal pay raise is a labor-market adjustment. Its purpose is to keep federal salaries reasonably competitive with private-sector pay, so agencies can recruit and retain employees. The COLA is a purchasing-power adjustment for retirement-related income. Its purpose is to keep a fixed retirement annuity or Social Security retirement benefits from losing value as consumer prices rise. One is about staying competitive in a job market; the other is about staying even with inflation. Because they answer different questions, there’s no reason to expect them to produce the same number in a given year — and most years, they don’t.
How the Federal Pay Raise Is Determined
The annual raise for General Schedule (GS) employees is set through a process that blends law, the President’s discretion, and Congress. The Federal Employees Pay Comparability Act (FEPCA) created a formula tied to the Employment Cost Index (ECI), which measures the change in wages and salaries across the broader labor market. In practice, the President has wide latitude to set an alternative raise by executive order, and Congress can also weigh in through appropriations language. The result is a figure that reflects economic and political judgment about what it takes to keep federal pay competitive — not a fixed, mechanical formula applied the same way every year. Locality pay is layered on top, so the raise a given employee sees also depends on where they work.
How the Retiree COLA Is Calculated
The retiree COLA works differently. It’s calculated using a specific measure of inflation — the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) — comparing the average CPI-W for the third quarter (July, August, September) of the current year to the same period the prior year. The Social Security Administration publishes the same CPI-W-based COLA that Federal Employees Retirement System (FERS) and Civil Service Retirement System (CSRS) annuitants receive, which is why the Social Security COLA and the federal retiree COLA are typically identical or very close. Unlike the pay raise, the COLA formula isn’t subject to a presidential or congressional override — it’s a straightforward calculation based on published government inflation data. The one place discretion enters is for FERS retirees: when the CPI-based COLA is between 2% and 3%, FERS annuitants receive a flat 2%, and when it exceeds 3%, they receive the full COLA minus one percentage point. CSRS retirees always receive the full CPI-based COLA.
| Feature | Federal Pay Raise | Retiree COLA |
|---|---|---|
| Who receives it | Current federal employees | FERS and CSRS annuitants (and survivors) |
| What it’s meant to do | Keep pay competitive with the private sector | Preserve purchasing power against inflation |
| Primary data source | Employment Cost Index (ECI) | Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) |
| Who sets it | President, with input from Congress | Calculated by formula; not subject to override |
| Applies evenly to everyone? | No — locality pay varies by area | FERS: capped/reduced above 2%; CSRS: full amount |
| Typical announcement timing | Executive order, usually late in the year | Mid-October, based on Q3 CPI-W data |
Why the Two Numbers Rarely Match
Because the pay raise reflects labor-market and political judgment while the COLA reflects a fixed inflation formula, the two can diverge significantly depending on economic conditions. In years of high inflation but a cooler labor market, retirees may see a larger COLA than the pay raise given to current employees. In years of strong wage growth but modest inflation, the pay raise can outpace the COLA. There’s no rule requiring them to stay in sync, and looking at historical patterns on the Office of Personnel Management’s (OPM) pay tables confirms how often they’ve differed from one year to the next.
What This Means for Retirement Planning
The practical takeaway is that a retirement income projection shouldn’t assume future annuity growth will track whatever raise is happening in the current pay table. FERS retirees, in particular, should plan around the diminished COLA formula — a 3% CPI-W reading becomes a 2% COLA increase, not 3%, in the FERS calculation described above. Anyone within a few years of retirement can track the current year’s projected COLA on the COLA Watch page, which is updated monthly as new inflation data comes in, and compare it against the latest GS pay table increases.
