The TSP Balance You Should Have at Every Age (Adjusted for the FERS Pension)

01 — The DistortionWhy the standard benchmarks overstate your target

The most-cited retirement benchmarks in the United States come from Fidelity: save 1× your salary by age 30, 3× by 40, 6× by 50, 8× by 60, and 10× by 67. Those numbers get reposted everywhere — but they bake in an assumption that doesn't apply to federal employees.

Fidelity's model explicitly assumes no pension income. The 10× salary target at age 67 is engineered to deliver roughly 45% of pre-retirement income from savings, with Social Security covering the rest. For a private-sector worker with no defined benefit plan, that math is appropriate. For a federal employee with a FERS pension, it's wrong in the direction of pushing you toward an unnecessarily large TSP target.

A FERS employee retiring at 62 with 30 years of service receives 33% of high-3 average salary from the pension alone, before Social Security. That's most of the way to Fidelity's 45% savings replacement target — without the TSP doing a single dollar of work. Layer Social Security on top, and the FERS pension plus Social Security can replace 55–70% of pre-retirement income before TSP withdrawals even start.

02 — Federal MathThe Fidelity framework, translated to federal

The Fidelity framework still works as a structure — federal employees just need different multiples. Below is the side-by-side: generic targets versus the same age points adjusted for a FERS pension assumption of 30 years of service at retirement at age 62.

Two cautions before treating these as gospel. First, these multiples assume a full FERS career — 30 years of service by age 62. A mid-career hire who joined federal service at 40 will have only 22 years of service at 62; their pension is smaller, so their TSP target is closer to the Fidelity number. Second, special-category employees (LEOs, firefighters, ATCs) have 1.7% pension multipliers on their first 20 years — their FERS-adjusted TSP target is lower still.

03 — Dollar TargetsTSP balance targets by age and grade

Multiples are abstract. Here's the same FERS-adjusted target, converted to dollars at common GS grades in the Rest-of-U.S. locality (17.06% adjustment). Salaries shown are mid-career Step 5 figures from the 2026 OPM pay tables.

These are TSP balance targets only. They do not include any other retirement accounts (Roth IRA, taxable brokerage, prior employer 401(k) rollovers), which most federal employees should also be building. They also use Rest-of-U.S. salaries — a federal employee in the Washington-Baltimore locality earns roughly 16% more than the RUS figure, so their nominal TSP target scales up proportionally. The pension scales up with them, though, so the multiple stays the same.

04 — Reading YourselfHow to read your number against the average

The FRTIB reports the average FERS TSP balance at $221,681 as of February 2026. That single number gets cited a lot, but it's almost useless as a personal benchmark — the average includes a 25-year-old GS-7 with $8,000 in their account and a 64-year-old GS-15 with $1.6 million. The right way to use it is as a sanity check on your own age and grade.

If you're 35 with a GS-12 salary and $80,000 in TSP

You're below the FERS-adjusted target of roughly $138K at age 35, but not catastrophically so. Five years of disciplined contributions at the 15% rate plus the match will get you on track. The win is recognizing the gap now, when 25+ years of compounding can still close it.

If you're 50 with a GS-13 salary and $250,000 in TSP

You're at roughly half of the $484K FERS-adjusted target. This is the most common situation for mid-career federal hires who weren't auto-enrolled, sat in G Fund for a decade, or had a career break. Catch-up contributions starting at 50 ($8,000/year additional in 2026) and the super-catch-up at 60–63 ($11,250/year) are designed for exactly this gap.

If you're 60 with a GS-14 salary and $850,000 in TSP

You're above the FERS-adjusted target of about $787K. A 30-year career FERS pension plus this TSP balance plus Social Security at full retirement age delivers a comfortable replacement ratio — and you have a few years left to add to it. The decisions ahead shift from accumulation to withdrawal strategy and tax planning.

The right benchmark isn't the FRTIB average. It's your own salary, your own years of service, and the pension that's already built in.

05 — Catch-Up MathWhat the catch-up math actually does at 50, 60, and 63

The IRS contribution limits have separate ceilings for three age windows. Understanding the difference between them is the cheapest, most impactful piece of TSP strategy a mid-career federal employee can pick up.

The super-catch-up is the underused one. A GS-14 turning 60, 61, 62, and 63 who maxes the higher window every year contributes $143,000 over those four years, against $130,000 at the standard 50+ catch-up rate. The extra $13,000, compounded at a 7% real return for an average 10 years of remaining work and early retirement, lands at roughly $25,500 in additional retirement wealth — purely from knowing the window exists.

One trap with 2026 rules: under SECURE 2.0, catch-up contributions must go into Roth TSP if you earned more than $150,000 in FICA wages during 2025. For most GS-14 and GS-15 employees in higher localities, that threshold is well below their base pay. Traditional catch-up isn't an option for high earners anymore — only Roth. Federal Warrior breaks down the Roth vs Traditional TSP decision for high earners specifically.

06 — Closing the GapClosing a gap: the highest-leverage moves

If the table in section 03 shows you're behind, here's the order of operations — most impact per unit of effort first.

1. Confirm you're capturing the full 5% match

Anything below a 5% contribution rate is leaving free agency money on the table. A GS-13 step 5 in DC earning roughly $138K who contributes 3% instead of 5% gives up $1,380 in match annually — that's the 1% of salary the agency would match at $0.50 on the dollar for the 4th and 5th percent of employee contributions. Over a 20-year remaining career at 7% real returns, that single 1% gap compounds to roughly $57,000 in missed wealth. Fix this before anything else.

2. Audit your fund allocation

If you were auto-enrolled before 2015 or moved everything to G Fund after a market scare, your allocation may be costing you 4–6 percentage points of annual return. A 45-year-old with 20 years to retirement sitting fully in G Fund will likely end with roughly 57% less than the same employee in a C Fund-weighted allocation. Federal Warrior has a full TSP fund allocation by age guide.

3. Step up contribution rate by 1% per year

The 5% match floor is the minimum, not the goal. Most retirement researchers target a 15% total savings rate (employee + employer). For a federal employee that means contributing 10% personally (10% + 5% match = 15%). Starting from 5%, raise contributions by 1% every January until you hit 10%. The pay raise typically absorbs the increase, so your take-home doesn't drop.

4. Use the catch-up windows when they open

At 50, the additional $8,000 is real money. At 60–63, the $11,250 super-catch-up is even bigger. Set a calendar reminder for January of the year you turn 50 and again at 60 to update your payroll election.

5. Don't take a TSP loan to fund anything optional

A TSP loan looks cheap because you're paying interest back to yourself, but the money is out of the market for the loan term. Five years out of a stock-heavy fund during a strong market is the single most common reason mid-career balances stall.

07 — Your NumbersRun your own numbers

The tool below uses the FERS-adjusted multiple framework — not generic Fidelity numbers — to show where your TSP should be at your current age, given your salary. It pulls the right multiple for your age bracket and applies it. Use the result as a directional check, not a precise retirement plan.

Two important caveats. This tool assumes a full FERS career (~30 years by 62). If your federal service started later in life, your pension will be smaller — meaning your TSP target moves up toward the Fidelity numbers. And it doesn't account for outside accounts (IRAs, brokerage, spousal retirement assets), which most federal households should also be building alongside TSP.
