When will the annuity begin?

Survivor election

A married retiree generally needs spouse consent to elect less than the full survivor benefit.

3. Supplement, FEHB and TSP planning

Social Security estimate at 62 — monthly

Eligibility result · MRA 57

Immediate, unreduced retirement

The entered age and service meet a standard OPM immediate-retirement combination.

Estimated FERS annuity after selected reductions

$3,000/mo

$36,000 per year before taxes, FEHB/FEGLI premiums and other deductions.

Survivor reduction0%

FERS supplement

$1,500/mo rough estimate

This rough estimate prorates the entered Social Security age-62 benefit by FERS service years. OPM uses an earnings-history computation, so the official amount can differ and is subject to the earnings test.

FEHB into retirement

Likely meets the planning checks

You appear to meet the enrollment-at-retirement and five-year/from-first-opportunity checks for carrying FEHB into an immediate retirement. Your agency and OPM make the final determination.

Projected TSP at separation

$493,397

The entered separation age meets the standard age-55 threshold for the qualified-plan early-distribution exception. Calendar-year timing and account type matter; verify before withdrawing or rolling to an IRA.

How to read your FERS estimate

The headline annuity starts with the OPM High-3 formula, applies any MRA+10 age reduction, then applies the survivor election you selected. It is a gross planning amount—not take-home pay. Federal and state taxes, FEHB, FEGLI, survivor premiums, deposits, court orders and other deductions can materially change the payment.

Why the separation age and annuity start age are different

The 1.1% multiplier looks at your age when you separate for retirement, not merely the age when a delayed annuity starts. Postponing an MRA+10 annuity can reduce or remove the age reduction, but it does not turn a separation before age 62 into the 1.1% formula.

Verify before filing. Use this result to compare dates and prepare questions, then confirm your service computation date, High-3, deposits, FEHB history and retirement route with your agency benefits officer and OPM.
