Rosa was 57, a GS-13 contracting officer, sitting in a retirement seminar at her agency when the presenter put up a slide showing a sample FERS pension. She did the math in her head. Then she did it again with her own numbers, which included a three-year stretch in her late thirties when she stayed home with her kids, then came back part-time for two years. The pension on the slide was not the pension she was going to get.

She wasn't behind because she'd done anything wrong. She was behind because a career that bends, as most do, gets paid out differently than a straight line.

That is the heart of retirement readiness among federal women and men. The benefits system is the same for everyone. The paths people take through it are not.

What the broad patterns show

Federal employment is often cited as one of the more equitable places to build a career. Pay is set by published schedules, and the retirement formulas don't ask your gender. That is real, and it narrows gaps that are wider in much of the private sector.

It doesn't erase them, though. Published participant data and outside research have tended to show a few consistent patterns:

  • Average TSP balances tend to be higher for men than for women at retirement age, tracking differences in salary, years of service, and time out of the workforce.
  • Women, on average, live longer, so the same dollars may need to stretch across more years.
  • Women are more likely to have career interruptions for caregiving, which affects service credit, high-3 salary, and years of contributions.
  • Women are more likely to be the surviving spouse, which makes survivor benefit decisions weigh more heavily.

These are averages. Plenty of women out-save the men in their offices, and plenty of men reach 62 with thin balances. Treat the patterns as a prompt to check your own situation, not as a forecast.

Where the gap actually comes from

It helps to see the mechanics, because the gap is rarely one big thing. It's a handful of small ones that compound.

The pension formula rewards length and high pay

Under FERS, the basic annuity is generally 1% of your high-3 average salary for each year of service, or 1.1% if you retire at 62 or later with at least 20 years. Two people, same agency, same grade:

  • Tom retires after 34 years with a high-3 of $110,000. At 1%, his pension is about $37,400 a year.
  • Maria retires after 28 years with a high-3 of $95,000. Her pension is about $26,600 a year.

Maria's pension is roughly 29% lower, even though she'd say she worked just as hard. Six fewer years and a lower salary base each take a piece, and they multiply. Part-time service can also reduce the computation, so if you've had a reduced schedule, ask your retirement specialist to run the actual numbers.

Fewer contribution years means less compounding

The TSP rewards time. Money contributed at 30 has decades to grow. Money contributed at 50 has far fewer. A three-year pause in your thirties costs you more than the contributions you skipped, because it also costs you the growth those dollars would have earned.

The agency contribution matters here too. FERS employees get an automatic 1% of pay, plus matching on the next 4%, for up to 5% total. Anyone contributing less than 5% is leaving free money behind. That's true for everyone, and it's a good first check whichever column you fall in.

Longevity changes the math

If you retire at 62 and plan on 30 years of retirement, that's a different budget than 22 years. The pension and Social Security both adjust for inflation in different ways, and the TSP balance has to cover the rest. Women planning for a longer horizon often need a more cautious withdrawal approach, and more attention to guaranteed income such as TSP annuities.

Decisions that matter more than people expect

Survivor benefits

When you retire, you choose whether to provide a survivor annuity for a spouse. Taking the maximum survivor benefit reduces your pension, and some couples decline it to get a larger check now. That can work, but it should be a joint decision made with the numbers in front of you, not a default. For a spouse who is likely to outlive the retiree, losing the pension at the first death can be a serious financial shock.

Spouses also have legal rights in TSP withdrawals and loans, with certain notarized consent requirements. Know what yours are.

Divorce and court orders

For people who divorced during their careers, a Retirement Benefits Court Order can direct part of a pension or TSP balance to a former spouse. Check what orders exist, and confirm that language in a decree actually matches what the plan can process. Vague settlement wording has caused real headaches.

Catch-up contributions

Once you turn 50, you can contribute above the standard annual limit. Recent law also created a higher catch-up amount for people in a specific age window in their early 60s. Limits change yearly and rules shift, so check tsp.gov and irs.gov for current figures before you set your election.

Practical moves, whatever your starting point

If you took time out, or your pay trajectory was uneven, you still have levers:

  1. Get your service history right. Request a service credit review. Military service, for instance, may be creditable with a deposit, and it's worth knowing early whether it applies.
  2. Raise your contribution rate in steps. Moving up one percentage point at each raise barely registers in your paycheck and adds up quickly.
  3. Use an IRA alongside the TSP. A Roth or traditional IRA adds flexibility. A spouse with little or no earned income may still be able to have a spousal IRA funded through the working spouse's income, subject to IRS rules and limits at irs.gov.
  4. Model your real retirement date. Retiring two years later can raise your pension, delay Social Security claiming, and give your TSP more time to grow, all at once.
  5. Coordinate as a couple. Two federal employees should compare retirement dates, survivor elections, and TSP allocations together, not separately.

Back to Rosa

After the seminar, Rosa asked for an estimate based on her actual service record. The number was lower than the sample. But she had seven years left before she planned to retire. She raised her TSP contribution from 8% to 12%, started making catch-up contributions at 50-plus levels, and decided to work until 62 to qualify for the higher 1.1% multiplier. By her own estimate, those three moves changed her retirement income meaningfully.

None of it required a different career. It required knowing her real numbers while she still had time to act on them.

That's the takeaway for both women and men. The averages describe a group. Your readiness is specific to you, and the earlier you look at it plainly, the more options you have.
