Our FERS retirement calculator analyzes your age, years of service, and birth year to determine all retirement pathways available to you. The calculator uses OPM eligibility rules to compute your Minimum Retirement Age (MRA), evaluate immediate retirement options, check early and deferred retirement eligibility, and provide personalized recommendations for optimal retirement timing.
The Minimum Retirement Age was designed to gradually increase from 55 to 57 for employees born after 1947. This graduated system means employees born just one year apart may have different MRAs, affecting when they can retire with 30 years of service or with 10+ years and reduced benefits.

FERS offers multiple retirement pathways, each with different age and service requirements. Understanding which paths you qualify for helps you make informed decisions about retirement timing. Some pathways offer unreduced benefits and the Special Retirement Supplement, while others involve benefit reductions or require special circumstances like agency early-out offers.
