TSP Milestone Benchmarks by Age: Am I On Track? (2026 Guide)

Last Updated: March 6, 2026 Reading Time: 10 min

Every week, federal employees post the same question on r/ThriftSavingsPlan: "I'm 38 with $110K in my TSP. Am I behind?" Most of the answers they get compare them to private-sector 401(k) benchmarks that assume zero pension income.

That's the wrong benchmark. Federal employees under FERS are in a fundamentally different situation. Here's what the data actually shows, and what "on track" actually means for a federal employee.

Key Takeaways

• Federal employees need 40-50% less in TSP than private-sector peers because the FERS pension and Social Security together replace roughly 53% of pre-retirement income.
• The average FERS TSP balance is $198,000 (2025 FRTIB data), but the median is only around $50,000. If you're near the average, you're ahead of most colleagues.
• A record 194,722 TSP accounts crossed $1 million as of January 2026. The average millionaire contributed for 27.8 years.
• The 2026 contribution limit is $24,500, plus $8,000 catch-up at age 50+ (or $11,250 super catch-up at ages 60-63).
• The three most expensive TSP mistakes: staying in the G Fund default, not using catch-up contributions at age 50, and taking TSP loans in your 40s.

Why You're Using the Wrong Benchmark

Fidelity and T. Rowe Price publish salary-multiple benchmarks that are widely cited in personal finance discussions. They look like this:

Age	Fidelity Target	T. Rowe Price Target
30	1x salary	0.5-1x salary
40	3x salary	2-3x salary
50	6x salary	3.5-5.5x salary
60	8x salary	6-11x salary

The problem: these targets assume you have no pension. They're built for private-sector workers whose entire retirement income depends on their 401(k) plus Social Security.

You have a pension. That changes everything.

A federal employee retiring at 62 with 30 years of service earning $100,000 draws from three income sources at once:

Income Source	Annual Income	% of Pre-Retirement Salary
FERS Pension (1.1% x 30 years)	$33,000	33%
Social Security (estimated)	$20,000	20%
TSP ($400K, 5% withdrawal)	$20,000	20%
Total	$73,000	73%

That's 73% income replacement with only $400,000 in TSP. Most financial planners target 70-80%. The generic benchmark would have told this same employee they need $800,000-$1,000,000. They don't.

This is why federal employees on Reddit feel anxious about balances that are actually fine. They're measuring themselves against a standard designed for people without a pension.

FERS-Adjusted TSP Benchmarks by Age

Here are the targets that actually apply to federal employees. These assume a $80,000 salary, 20+ years of service, and full FERS pension eligibility.

Age	Generic Target (Fidelity)	FERS-Adjusted TSP Target	Notes
30	$80,000 (1x)	$30,000-$50,000	Capture the full match, build the habit
40	$240,000 (3x)	$100,000-$150,000	Pension reduces TSP burden significantly
50	$480,000 (6x)	$200,000-$300,000	Start catch-up contribution planning
60	$640,000 (8x)	$300,000-$500,000	On track for a solid retirement
Retirement	$800,000 (10x)	$400,000-$600,000	TSP plays a supplemental income role

One important caveat: these adjusted targets assume 20+ years of federal service and full pension eligibility. If you have fewer than 20 years of service, or you're uncertain about staying federal for a full career, you should weight your TSP targets closer to the private-sector benchmarks. A smaller pension means TSP must do more work.

TSP Benchmarks by Years of Federal Service

The best proxy for "Am I on track?" isn't your age. It's your years of service. This table uses March 2025 FRTIB data showing the actual distribution of participant balances alongside average contribution years.

What the Official FRTIB Data Shows

Balance Range	Participants	Average Years Contributing
Under $50,000	4,322,634	6.0 years
$50,000-$249,999	1,804,461	14.6 years
$250,000-$499,999	588,795	20.3 years
$500,000-$749,999	241,460	23.3 years
$750,000-$999,999	118,681	25.3 years
$1,000,000+	146,910	28.6 years

Source: FRTIB 2024 Annual Report via FedSmith

Reading this table: if you have 14-15 years of service and $80,000 in your TSP, you're right in the middle of the $50,000-$249,999 band. You're not behind. You're typical.

Projected Benchmarks: "Am I On Track?" by Age and Years of Service

These projections use 7% average annual return, 5% employee contribution plus 5% agency match (10% total), and approximate GS mid-career salary levels.

Age	Years of Service	"Minimum" TSP	"On Track" TSP	"Ahead" TSP
28	5 years	$20,000	$40,000	$65,000+
33	10 years	$50,000	$90,000	$150,000+
38	15 years	$100,000	$175,000	$280,000+
43	20 years	$175,000	$310,000	$480,000+
48	25 years	$280,000	$510,000	$750,000+
53	30 years	$430,000	$800,000	$1,100,000+
58	35 years	$600,000	$1,100,000	$1,500,000+

"Minimum" = 5% plus 5% match at a modest ~5% return. "On Track" = 10-15% total contributions at 7% return. "Ahead" = maxing out or near-maxing at 15%+ total contribution rate.

Projections by Contribution Rate (Starting $75,000 Salary, 7% Return)

If you contribute 5% plus get the 5% match (10% total):

Years of Service	Approximate Age	Projected Balance
5 years	Age 27	~$34,000
10 years	Age 32	~$89,000
15 years	Age 37	~$175,000
20 years	Age 42	~$313,000
25 years	Age 47	~$514,000
30 years	Age 52	~$800,000

If you contribute 15% plus get the 5% match (20% total):

Years of Service	Approximate Age	Projected Balance
5 years	Age 27	~$68,000
10 years	Age 32	~$178,000
15 years	Age 37	~$350,000
20 years	Age 42	~$626,000
25 years	Age 47	~$1,028,000
30 years	Age 52	~$1,600,000

Doubling your contribution rate, roughly, doubles your ending balance. The earlier you start, the more that compounding does the heavy lifting.

Average TSP Balances: What the Data Actually Shows

Here's what FRTIB data shows for TSP balances across age groups (2024-2025):

Age Group	Average TSP Balance	Estimated Median
Under 30	~$17,000	~$8,000
30-39	~$60,000-$91,000	~$30,000
40-49	~$168,646	~$80,000
55-64	~$244,750	~$120,000
65+	~$272,588	~$130,000

Source: Federal Pension Advisors citing FRTIB data; FersRetirementPlanner.com

The gap between average and median is significant. A few high-balance accounts pull the average up. If you're at the average for your age group, you're ahead of most colleagues. If you're at the median, you're right in the middle of the pack.

One other data point worth knowing: the overall average FERS TSP balance in 2025 is $198,000, according to Federal Pension Advisors citing FRTIB data. The median is only around $50,000. The math holds across the entire federal workforce.

The TSP Millionaire Picture in 2026

As of January 1, 2026, there are 194,722 TSP millionaires, a record high. That's up from 157,760 at the end of 2024, a gain of 37,000 accounts in one year.

Metric	Data
Total TSP millionaires (Jan 2026)	194,722
Year-over-year increase	+37,000
Share of all TSP participants	2.37%
Total TSP participants	7.28 million
Average years contributing (millionaires)	27.8 years
Largest single TSP account	$9.96 million
Total TSP assets (year-end 2025)	$1.073 trillion

Source: FedSmith, January 2026

The typical TSP millionaire didn't do anything exotic. They started contributing in their late 20s to early 30s, stayed consistent for about 28 years, and invested primarily in stock funds (C, S, I) rather than the G Fund.

How long does it actually take at different scenarios:

• Max out ($24,500/year) starting at 25, 7% return: ~21 years, hitting $1M at age 46
• Max out starting at 35, 7% return: ~23 years, hitting $1M at age 58
• 5% plus 5% match at $100,000 salary starting at 25, 7% return: ~33 years, hitting $1M at age 58
• 5% plus 5% match at $100,000 salary starting at 35, 7% return: Does not reach $1M by age 62

That last point matters. The match-only approach works for a functional retirement with a full FERS pension. It does not produce TSP millionaire status unless you start very early.

2026 Contribution Limits and Catch-Up Rules

For 2026, the TSP contribution limits are:

Category	2026 Annual Limit	Per Pay Period (26 periods)
Under age 50	$24,500	$942.31
Age 50-59 and 64+ (catch-up)	$32,500 total	~$1,250
Ages 60-63 (super catch-up)	$35,750 total	~$1,375

Source: TSP.gov Bulletin 25-3

The super catch-up provision for ages 60-63 is a SECURE 2.0 change that took effect in 2025. If you're in that window, you can contribute $11,250 more per year than the standard catch-up. That's a significant acceleration opportunity.

One critical warning on catch-up contributions: They don't apply automatically. You must actively elect them. Many federal employees in their 50s don't know this. An employee who starts catch-up contributions at 50 and continues through 62 at $8,000/year additional, at 7% return, adds approximately $152,000 to their retirement balance compared to not using catch-up at all.

Another warning on front-loading: Don't hit the annual limit before year-end. If you max out by October and stop contributing, you stop receiving agency matching for the remaining pay periods. For a $90,000 salary employee, that costs $1,800 in matching per year. Spread contributions evenly across all 26 pay periods.

For employees earning more than $150,000 in prior-year FICA wages (most GS-14s, GS-15s, and SES), catch-up contributions must go into a Roth TSP account under the 2026 mandatory Roth catch-up rule.

The Six Mistakes That Put Federal Employees Behind

Mistake 1: Staying in the G Fund (Pre-2015 Hires)

Before September 2015, all new federal employees were auto-enrolled into the G Fund. At its peak, employees under 29 had 41.7% of their assets there. Since the default changed to age-appropriate L Funds, new entrants hold only 1.46% in the G Fund.

But many employees hired before 2015 never switched. A 40-year-old who has been 100% G Fund since 2010 compounded at roughly 2.5% versus 7%+ in diversified stock funds. On a $100,000 balance over 15 years, that's $144,000 (G Fund) versus $276,000 (diversified). A $132,000 gap from a single allocation mistake.

The G Fund is valuable for capital preservation near retirement. It's not appropriate as a long-term growth vehicle for employees 10+ years from retirement.

Mistake 2: Only Contributing 5%

Getting the full match is the minimum. Here's what 5% plus 5% match looks like at a $100,000 salary, retiring at 62:

Starting Age	Balance at 62 (5% + 5%, 7% return)
25	~$1,160,000
30	~$804,000
35	~$548,000
40	~$364,000

Starting at 35 with match-only contributions produces $548,000. With a full FERS pension, that's workable. But it leaves very little margin for healthcare inflation, unexpected expenses, or helping adult children. Employees who want real financial flexibility should target 10-15% total employee contribution.

Mistake 3: Skipping Catch-Up Contributions at Age 50+

The $8,000 catch-up contribution is money you'd otherwise send to the IRS now versus later. An employee who skips it from age 50 through 62 misses roughly $152,000 in additional retirement assets, according to calculations based on FRTIB data via FedSmith.

Mistake 4: Taking TSP Loans in Your 40s

TSP loan usage was highest among the 40-49 age cohort at 12% in 2024, according to GovExec reporting on FRTIB data. That's the decade when a steady contribution rate starts producing the biggest dollar gains.

A $25,000 loan at age 42 that takes 5 years to repay costs approximately $35,000 in foregone compound growth by retirement at 62 (assuming 7% returns). The loan repayments rebuild the balance, but the growth you would have earned during that time is gone permanently.

Mistake 5: Moving to 100% G Fund During Market Downturns

Employees who shifted to the G Fund during the March 2020 COVID crash (market down 34%) missed the full recovery. The C Fund returned 32.3% that year once the rebound kicked in. G Fund savers earned roughly 2.5%. FRTIB data show that investors who stay in stock funds through downturns come out ahead of those who try to time the market.

Mistake 6: Not Knowing About the FERS Pension's Role in the Math

The most common TSP anxiety on Reddit comes from comparing to private-sector benchmarks. A federal employee with $85,000 at age 35 and 12 years of service is not behind. They're building supplemental income on top of a pension that will replace a third of their salary. Use the right benchmark for your situation.

The Agency Match: Worth More Than You Realize

The 5% FERS agency match structure works as follows:

• 1% automatic contribution (no employee contribution required)
• 3% dollar-for-dollar match (on first 3% you contribute)
• 1% match at 50 cents per dollar (on next 2% you contribute)
• Total: 5% match when you contribute at least 5%

For a federal employee starting at $90,000 with 1% annual raises and 8% investment return, the match alone grows to approximately $513,173 over 30 years, according to FedSmith's 2024 analysis.

The comparison between 3% and 5% contributions is stark:

Contribution Level	30-Year Ending Balance
3% employee + 4% match	$817,908
5% employee + 5% match	$1,168,459
Difference	$350,551

Not contributing at least 5% means forfeiting $350,000+ in matching funds over a 30-year career.

Frequently Asked Questions

How much should I have in my TSP by age 35?

For a federal employee with 10-13 years of service contributing 10-15% total, the on-track target at age 35 is approximately $90,000-$175,000. Unlike private-sector peers, federal employees under FERS have a pension that reduces their TSP burden. The generic Fidelity benchmark of 2x salary is too high for feds with a full pension. Use the FedTools TSP Calculator to model your specific situation.

Is $100,000 in TSP enough to retire?

On its own, no. At a 4% withdrawal rate, $100,000 produces only $4,000 per year. But for a federal employee with 30 years of service, the FERS pension and Social Security already replace roughly 53% of pre-retirement income. A $300,000-$600,000 TSP balance is what most federal employees need for a comfortable retirement, depending on years of service and lifestyle goals.

What is the average TSP balance for a 45-year-old federal employee?

The average TSP balance for federal employees in the 40-49 age bracket is approximately $168,646, according to 2025 FRTIB data. The median is significantly lower, around $80,000-$90,000. Most 45-year-olds have less than the average. Federal employees with 20+ years of service who have consistently contributed 10%+ are well ahead of this figure.

How do I know if I'm on track given my federal pension?

Add up projected retirement income from all three FERS sources. Your pension covers roughly 1-1.1% per year of service times your high-3 salary. Social Security replaces 20-35% of salary. TSP fills the remaining gap to your income replacement target (typically 70-80%). If pension plus Social Security already covers 50-60%, you only need TSP to generate 10-20% of pre-retirement salary. Use the FERS Retirement Calculator alongside the TSP Calculator to see your complete picture.

How long does it take to reach $1 million in TSP?

As of January 2026, 194,722 federal employees have crossed the $1 million mark, a record. The average TSP millionaire contributed for 27.8 years. If you maximize at $24,500/year starting at age 25 with 7% returns, you reach $1 million in about 21 years. Starting at 35 takes about 23 years. At the match-only level with a $100,000 salary starting at 25, you reach $1 million around age 58.

Should I compare my TSP to 401(k) benchmarks?

No. Private-sector 401(k) benchmarks assume no pension. Federal employees under FERS have a pension that replaces 30-33% of salary after 30 years, plus Social Security at around 20%. Your TSP only needs to generate 15-20% of income replacement. Private-sector workers need their 401(k) to generate 50-70%. Your on-track TSP balance is roughly 40-50% of what private-sector peers need.

Can I catch up if I started late?

Yes, especially with catch-up contributions. At age 50+, you can contribute up to $32,500 per year. At ages 60-63, the super catch-up allows $35,750 per year. An employee who starts maxing catch-up contributions at 50 and continues for 12 years at 7% return will have approximately $370,000 by age 60. Combined with a FERS pension and Social Security, that is a functional retirement.
