FERS Retirement Calculator

For most non-disability retirements, multiply your high-3 average salary by your years and full months of creditable service, then multiply by 1%. For an eligible immediate retirement at age 62 or older, the factor becomes 1.1% when computation service reaches 20 years. OPM BAL 18-103 confirms that eligible unused-sick-leave credit can reach that computation threshold, although it cannot make you eligible to retire.

Enter your highest average basic pay during any three consecutive years of federal service. It is not simply your final salary or total gross compensation. Pay normally must be subject to retirement deductions; overtime, bonuses and most allowances are excluded.

No. Sick leave can increase computation service for an immediate annuity or a postponed MRA+10 annuity, but it cannot satisfy an age or service eligibility threshold. At age 62, it can help an already-eligible immediate retiree reach 20 computation years for the 1.1% formula. A true deferred annuity does not receive sick-leave credit. This estimator uses the rounded whole-month thresholds in OPM's 2,087-hour conversion chart.

This calculator accepts completed years and months of actual service, while an agency record can include residual days. Because OPM combines those days with converted sick leave before dropping the final remainder, this planning estimate can be up to about one service month low. Use your agency or OPM estimate for the official amount.

Yes, by one monthly step. This calculator accepts age and commencement in completed months, while OPM adjudicates exact dates. One additional full month below age 62 changes the reduction by 5/12 of 1 percentage point. Use the agency or OPM calculation for an exact commencement date.

The reduction is 5/12 of 1% for each full month your annuity starts before age 62. It is eliminated with at least 30 years of service, or with at least 20 years when the annuity begins at age 60 or later. Postponing the start date can reduce or eliminate it.

No. OPM's 1.1% rule requires an eligible immediate retirement at age 62 or older and 20 years of computation service. A deferred annuity beginning at 62 excludes unused sick leave and does not turn an earlier separation into an age-62 immediate retirement. This calculator keeps separation age and annuity start age separate for that reason.

A maximum FERS spouse survivor election generally reduces your annuity by 10% and can pay an eligible spouse 50% of the unreduced earned annuity. A partial election reduces it by 5% and can pay 25%. A married employee generally needs spousal consent to elect less than the maximum.

No. The supplement uses a separate Social Security-style computation and has its own eligibility and earnings-test rules. The result here is the estimated FERS basic annuity before the supplement, taxes, insurance deductions and COLAs.

No. It is a planning estimate built from current published formulas and the facts you enter. Your agency and OPM verify creditable service, high-3 pay, deposits, part-time work, special coverage, court orders and the actual payable benefit.
