FERS pension COLA 2026

FERS retirees often search the Social Security COLA first, but the FERS annuity COLA can be different. The plan needs the actual federal annuity increase.

Short answer

The 2026 FERS COLA is 2.0 percent for eligible FERS annuities.

OPM lists the 2026 cost-of-living adjustment for eligible FERS annuities at 2.0 percent. SSA announced a 2.8 percent Social Security COLA for 2026, so the two numbers are not the same.
