When is the optimal age to retire under FERS?

The optimal FERS retirement age depends on your specific career timeline. Retiring at 62 or later with 20+ years unlocks the 1.1% pension multiplier (vs. 1%), adds more years of service to the pension formula, and allows continued FEHB and TSP contributions. Use a retirement timing calculator to model your specific break-even point.

What is the break-even age for delaying FERS retirement?

The break-even age for delaying retirement is typically 10–14 years after your potential early retirement date. For example, delaying from MRA+30 to age 62 costs several years of pension income but gains the 1.1% multiplier and higher high-3. A timing calculator shows the exact crossover point for your situation.

Does working longer significantly increase the FERS pension?

Yes. Each additional year adds to both your years-of-service count and potentially your high-3 average salary. Combined with the 1.1% multiplier bonus at 62+20, working to age 62 instead of MRA (57) can increase the pension by 30–40% in many scenarios.

What this means

Not shown: FERS Annuity Supplement. If you retire at MRA with full-career service (30+ YOS) before age 62, you may also receive the FERS Annuity Supplement — a bridge payment until SS begins at 62. This tool does not currently model that benefit. It could add $10,000–$20,000/year to your pre-62 income depending on your SS earnings history. Consult OPM or your agency HR for your eligibility and estimated amount.

Social Security timing is separate from when you retire from federal service. Delaying SS from 62 to 70 can increase your benefit by up to 32%. That decision happens independently of your federal retirement date. The SS column above assumes your stated claim age.

Note: retirement income is typically taxed at a lower effective rate than working income — no payroll taxes, lower bracket, standard deduction still applies. Your after-tax cash flow gap is likely smaller than the headline figure above.
