How Do I Figure Out My Net Monthly Income as a Federal Retiree?

One of the most common questions federal employees ask as retirement nears is, “How much will actually land in my bank account each month?” Gross numbers on a benefits estimate look reassuring, but your real financial stability depends on what’s left after deductions.

What does my retirement paycheck really look like? Let’s break it down piece by piece, so you can build an accurate, informed picture of your post-retirement income.

The Building Blocks of Your Retirement Paycheck

Your net monthly income in retirement is typically pieced together from several sources, not one single check:

• FERS Pension (Basic Benefit) → your monthly annuity based on your high-3 salary and years of service
• FERS Supplement → a bridge payment for those who retire before age 62 and before Social Security eligibility
• TSP withdrawals → income you elect to draw from your Thrift Savings Plan
• Social Security → begins once you file, typically at 62 or later

Each of these pieces is taxed and deducted differently, which is why simply adding up gross figures can be misleading.

Comparing Your Working Paycheck to Your Retirement Paycheck

While you’re working, your paycheck goes through a familiar set of deductions: federal and state tax withholding, FERS retirement contributions, TSP contributions, FEHB premiums, and FEGLI premiums. Once you retire, the paycheck structure changes — some deductions disappear, others continue, and a few show up in new forms.

Working Paycheck:

Includes deductions for FERS contributions, TSP contributions, FEHB premiums, FEGLI premiums, Social Security and Medicare payroll taxes, and federal/state income tax.

Retirement Paycheck (Annuity):

No more FERS or TSP contributions come out, and Social Security and Medicare payroll taxes no longer apply to your annuity. But FEHB premiums typically continue (now paid directly from your annuity — and no longer on a pre-tax basis, so the same premium costs slightly more after taxes), FEGLI premiums may continue at a reduced or increasing cost depending on your election, federal/state income tax still applies to your pension and TSP withdrawals, and if you elect a survivor benefit, that reduction comes off the top of your annuity — more on that below.

This shift is one reason a “gross-to-net” comparison matters more in retirement planning than most people expect. Understanding which deductions stop and which continue is a key part of the retirement process — but deductions are only half the picture. For many federal employees, the timing of one income source in particular can make or break those early retirement years: the FERS Supplement.

The FERS Supplement: A Bridge, Not a Permanent Benefit

If you retire before age 62, you may be eligible for the FERS Supplement — designed to approximate the Social Security benefit you’ve earned through federal service, until you’re eligible to file for actual Social Security. Eligibility generally requires retiring on an immediate, unreduced annuity — employees who retire under the MRA+10 provision do not receive it. This can meaningfully affect your monthly cash flow in the early retirement years.

A few things worth knowing:

• The Supplement ends at age 62, regardless of when you file for Social Security
• It is subject to an earnings test if you continue working → income above a certain threshold can reduce or eliminate it
• No COLAs → unlike Social Security, the Supplement is not adjusted for inflation

Because the Supplement disappears at 62, many retirees lean on TSP withdrawals to help cover that gap — which makes your withdrawal strategy worth planning well in advance.

TSP: Your Flexible, Self-Directed Piece

Unlike your pension, your TSP withdrawals are largely within your control — how much, how often, and from which funds. That flexibility is powerful, but it also means the responsibility for maximizing benefits and avoiding shortfalls falls to you.

• Required Minimum Distributions (RMDs) → begin at age 73 (age 75 if you were born in 1960 or later) and can affect your tax picture
• Withdrawal strategy → lump sum, installments, or annuity purchase, each with different tax and income implications
• Taxes → traditional TSP withdrawals are taxed as ordinary income, while qualified Roth withdrawals are generally tax-free

Navigating your TSP withdrawal strategy alongside your pension and Social Security timing is where a strategic review can add real value.

Income sources are only one side of the equation, though — what comes out of your check each month matters just as much, and that’s where FEGLI often gets overlooked.

FEGLI: A Deduction That Can Grow Over Time

Federal Employees’ Group Life Insurance (FEGLI) is often overlooked when estimating net retirement income. If you carry FEGLI into retirement, premiums for certain options can increase with age, sometimes significantly. It’s worth reviewing your FEGLI elections well before retirement to understand:

• Coverage elections → whether you’ll keep Basic, Option A, B, or C, each with a different cost structure
• Premium schedule → how costs step up at ages 50, 55, 60, 65, and beyond
• Alternatives → whether reducing coverage or exploring private life insurance may better fit your retirement budget

The Survivor Benefit Election: A Big Deduction That’s Easy to Miss

For married retirees, one of the largest reductions to the FERS annuity is one you choose on purpose: the survivor benefit election. It rarely appears on back-of-the-envelope estimates, yet it comes off the top of your pension every month.

• Full survivor benefit → costs 10% of your annuity; your spouse receives 50% of it after your death
• Partial survivor benefit → costs 5% of your annuity; your spouse receives 25%
• FEHB connection → in most cases, a survivor election is required for your spouse to keep FEHB coverage after you’re gone — often the deciding factor

Because this election is largely irrevocable after retirement, it deserves careful analysis before you file — sometimes alongside a comparison to life insurance alternatives.

Bringing It All Together

Calculating your true net monthly income means starting with your pension and Supplement (if applicable), subtracting any survivor benefit reduction and continuing deductions like FEHB and FEGLI, factoring in taxes, and layering in TSP withdrawals and Social Security when appropriate. It’s a more layered calculation than most people expect — but it’s one of the most important steps in creating a realistic retirement budget.

A written checklist comparing your current paycheck to your projected retirement paycheck, line by line, can make this process far less abstract and far more actionable.

What This Might Look Like: A Hypothetical Example

Consider a hypothetical federal employee retiring at age 60 with 30 years of service and a high-3 average salary of $100,000. Her gross FERS annuity is $30,000 per year — $2,500 per month.

Here’s how that gross figure might translate into an actual monthly deposit: 

This example is hypothetical and for illustration only — your premiums, withholding, and Supplement will differ. One note on state taxes for our Kansas City–area readers: Kansas exempts federal civil service annuities from state income tax, while Missouri offers a partial public-pension exemption.
