VERA/VSIP Buyout Decision Calculator (2026)

If your agency has offered a Voluntary Early Retirement Authority (VERA) window or a Voluntary Separation Incentive Payment (VSIP), you are facing one of the most consequential and time-pressured financial decisions of your career. Decision windows are typically 30–60 days, the math is non-obvious, and there is no undo. This calculator shows your FERS annuity if you retire now versus waiting 1, 2, or 3 years, the estimated net value of your VSIP after federal withholding, how many years of your pension increase the VSIP is worth, and whether key benefits — FEHB, the FERS supplement, and TSP penalty-free access — follow you into retirement.

What this calculator covers: VERA eligibility check · FERS annuity under each timeline · VSIP net after 22% federal supplemental withholding · Break-even analysis · FEHB 5-year rule · FERS supplement eligibility · TSP Rule of 55.

Designed for FERS employees. CSRS annuity is shown using the tiered formula (1.5%/1.75%/2%) — CSRS employees do not receive a FERS supplement. Survivor annuity election (reduces annuity by 10% for 50% survivor or 5% for 25% survivor) is not modeled — run the Survivor Annuity Calculator separately.
Used to check VERA eligibility (50+ with 20 years OR any age with 25 years), TSP Rule of 55, and FERS supplement timing. If you plan to retire in a few months, use your age at separation.
Include any paid military buyback time. Do not include sick leave credit (it adds to service for annuity but is not creditable for VERA eligibility or supplement). Your official total is on your SF-50 or HR Benefits Statement — verify before deciding.
Your average basic pay (base + locality, no overtime or awards) over your 3 highest consecutive salary years. Use your current salary as a conservative estimate. The annuity comparison below uses the same high-3 for all scenarios — if you expect a step increase or promotion in the next 1–2 years, your actual gain from waiting will be somewhat higher than shown. See the High-3 Calculator for a precise projection.
Most employees hired after January 1, 1987 are FERS. Check your SF-50 if uncertain. CSRS Offset employees are treated as CSRS for the annuity formula below.
To carry FEHB into retirement, federal law requires continuous enrollment in any FEHB plan for the 5 years immediately preceding your retirement date (or your entire federal career if less than 5 years). If you dropped and re-enrolled, count from the most recent re-enrollment.
VSIP has been capped at $25,000 since the 1990s. DoD has occasionally received authority for higher amounts. If you received no VSIP and are evaluating VERA alone, select "VERA only."

What changes when you retire under VERA

The most important fact about VERA: there is no annuity reduction penalty. Under the normal MRA+10 early retirement option, you lose 5% of your annuity for every year you are under age 62 — a 50% cut for a 52-year-old. VERA eliminates this penalty entirely. Your annuity is calculated the same way as any standard FERS retirement.1

What does change:

What does NOT change under VERA

Several critical items are unchanged by VERA vs. regular retirement:

How to interpret the break-even

The break-even in this calculator answers a specific question: If I work one more year instead of taking VERA, how many years of retirement does it take before my additional annual pension equals the VSIP payment I'm passing up?

It does not include the salary income you'd earn by working that year (which is also significant), so it is a conservative measure — weighted toward making VERA look better than it might be in a full analysis. A complete picture requires comparing:

For most full-career federal employees in the $100,000–$180,000 salary range, working 1 additional year generates $40,000–$80,000 in after-tax salary plus $1,000–$1,800/year in permanent additional pension. The $25,000 VSIP typically covers a fraction of that combined value — which is why accepting VERA primarily makes sense when you have a concrete plan for your time and income after leaving: a private-sector role, a business, a caregiving situation, or a deliberate lifestyle choice.

If your main reason is...VERA/VSIP considerations
You have a private-sector job offerOften makes sense — post-retirement income replaces the salary year; pension comparison becomes the key variable
Work stress / desire to stopCan make sense — but model the monthly income carefully; many people underestimate the OPM interim pay gap in the first 2–3 months
Health concernsShorter expected retirement duration changes the break-even math significantly — earlier collection is more valuable
You don't have a clear income planBe cautious — see the First Year of Federal Retirement guide for the cash flow reality

Get your VERA/VSIP scenario modeled

The calculator gives you directional numbers. What it can't model: the interaction between your VERA retirement date and your specific high-3 window, sick leave balance optimization, VSIP tax impact in your state, TSP withdrawal sequencing from your current balance, and Social Security timing combined with the FERS supplement cliff at 62. A federal benefits specialist runs the integrated model — calibrated to your exact situation, not an approximation.

  1. OPM — Voluntary Early Retirement Authority (opm.gov). VERA eligibility criteria: age 50 with 20 years of creditable service, or any age with 25 years. Under VERA, there is no annuity reduction penalty; the annuity formula is the same as under a standard immediate FERS retirement (5 U.S.C. § 8414(b)). Agencies must receive OPM authorization before offering VERA; employees must be in covered positions for the minimum period specified. Verified June 2026.
  2. OPM — Voluntary Separation Incentive Payments (opm.gov). VSIP cap: $25,000 under 5 U.S.C. § 3523(b)(3)(B). VSIP is treated as ordinary income; federal income tax is withheld at the supplemental rate (22% in 2026 per IRS Rev. Proc. 2025-67). State income taxes vary. VSIP does not affect the FERS annuity calculation. Verified June 2026.
  3. OPM — FERS Annuity Computation (opm.gov). FERS multiplier: 1.0% per year of creditable service (5 U.S.C. § 8415(a)); 1.1% if retiring at age 62 or older with 20 or more years of creditable service. The enhanced 1.1% rate applies to all service years, not just the service above 20 years. Sick leave credit is excluded from the 20-year threshold under § 8415(f). Verified June 2026.
  4. OPM — FERS Special Retirement Supplement (opm.gov). FERS supplement eligibility: immediate retirement with at least 20 years of creditable service and at or above MRA, or retirement at age 60/62+ with appropriate service. Under VERA at or above MRA, supplement starts at retirement date. Under VERA below MRA, supplement is deferred until MRA. Supplement ends at age 62 regardless of whether the retiree files for Social Security. 2026 earnings test threshold: $24,480. Verified June 2026.
