Hey Reader,

A few months ago I sat across a table from a veteran, 16 years in, college-educated, the kind of person who never misses an LES discrepancy. Budget tighter than a fresh bootlace.

Then I looked at his TSP.

Three different L Funds. An overlapping mix of C, S, and I Fund allocations stacked on top. Money scattered across target dates that didn’t match his actual retirement timeline, or each other.

His allocation strategy was more complicated than night land nav at Fort Benning without a compass.

And here’s the thing: he didn’t know. Not because he was careless. Because the TSP doesn’t exactly send you a notification that says, “Hey, your funds are fighting each other.”

He’d clicked a few buttons over the years, accepted whatever defaults showed up during open season, and assumed it was handled.

It wasn’t.

When I walked him through what he was actually holding, the overlapping equity exposure, the drag from competing glide paths, the mismatch between his allocation and his real timeline, his exact words were: “Why didn’t anyone tell me this?”

I’ve heard some version of that sentence from almost every veteran I’ve worked with.

So let me tell you.

Mistake #1: The “Set It and Forget It” Trap

This is the big one. You picked your allocation during in-processing, maybe glanced at it once during a PCS, and never touched it again.

The TSP doesn’t penalize you for ignoring it. It just quietly lets your allocation drift. The problem is that a 25-year-old E-3’s risk tolerance and a 40-year-old O-4’s retirement timeline are not the same thing. But if you never updated, your TSP still thinks you’re 25.

Here’s what that may cost you: the TSP has over $1 trillion in assets and serves more than 7.2 million accounts. Nearly 195,000 participants are TSP millionaires. But average balances for BRS participants sit around $17,000. The gap between those two numbers tells a story about intentionality.

The fix: Log into tsp.gov this week. Look at your current allocation. Ask yourself: does this reflect who I am now, or who I was when I first enrolled?

Mistake #2: Stacking L Funds Like MRE Cases

This is the big one. You picked your allocation during in-processing, maybe glanced at it once during a PCS, and never touched it again.

The TSP doesn’t penalize you for ignoring it. It just quietly lets your allocation drift. The problem is that a 25-year-old E-3’s risk tolerance and a 40-year-old O-4’s retirement timeline are not the same thing. But if you never updated, your TSP still thinks you’re 25.

Here’s what that may cost you: the TSP has over $1 trillion in assets and serves more than 7.2 million accounts. Nearly 195,000 participants are TSP millionaires. But average balances for BRS participants sit around $17,000. The gap between those two numbers tells a story about intentionality.

The fix: Log into tsp.gov this week. Look at your current allocation. Ask yourself: does this reflect who I am now, or who I was when I first enrolled?

Mistake #3: The G Fund as a Security Blanket

The G Fund is a remarkable instrument. Government-backed, no risk to principal, and it earned about 4.4% in 2025. For capital preservation near retirement, it’s hard to beat.

But here’s the tension: if you’re 38 years old and 60% of your TSP is in the G Fund, you’re essentially choosing safety over growth for money you won’t touch for 20+ years. Meanwhile, The Silent Thief; inflation is quietly eroding your purchasing power every single year.

The C Fund, which tracks the S&P 500, returned 17.9% in 2025. The I Fund returned 32.5%. Over the past decade, the C Fund has consistently ranked in the top quartile of large-blend funds. The G Fund’s 10-year annualized return sits around 2.8%.

I’m not saying the G Fund is bad. I’m saying it’s a tool, not a strategy. A hammer is a great tool. But you wouldn’t use it to cut wood.

The fix: Consider your actual time horizon. If retirement is 15+ years away, evaluate whether your G Fund allocation matches your timeline or your anxiety. Those are two different things.

Mistake #4: Ignoring the Beneficiary Designation

This one is quiet. And potentially devastating.

Your TSP beneficiary designation is separate from your will. It’s separate from your SGLI. It’s separate from your SBP election. If you filled out that form at 22 and you’re now remarried with children, your TSP may still be earmarked for someone from a previous chapter of your life.

I’ve seen it. More than once. And the consequences for families can be severe.

The fix: Go to tsp.gov right now. Click “Beneficiaries.” Verify the names. If your life has changed, marriage, divorce, children, loss, your beneficiary designation should change too. This takes five minutes. It may be the most important five minutes you spend this month.

Mistake #5: The Rollover Decision by Default

When you separate or retire, the TSP doesn’t force you out. Your money can stay right where it is. And for some veterans, that’s the right call, the TSP’s expense ratios (0.048% to 0.079%) are among the lowest in the industry.

But “leave it alone because I don’t know what else to do” is not a strategy. It’s avoidance.

A rollover to an IRA may give you access to thousands of additional investment options, more control over beneficiary designations, greater flexibility for Roth conversions, and the ability to coordinate your TSP with your pension, VA disability compensation, and civilian retirement accounts.

For 2026, the TSP contribution limit is $24,500, plus $8,000 in catch-up contributions if you’re 50 or older. And if you’re between 60 and 63, you may be eligible for the enhanced catch-up of $11,250 under SECURE 2.0. Plus, in-plan Roth conversions are now available within the TSP itself. These are meaningful planning tools.

The fix: Don’t let inertia make this decision for you. Whether you stay, roll, or do a hybrid approach, make it an intentional choice based on your full financial picture, not a default.

Why This Matters Beyond the Numbers

Proverbs 27:23 says, “Be sure you know the condition of your flocks, give careful attention to your herds.”

Your TSP is one of your flocks. It’s not glamorous. It doesn’t make for exciting dinner conversation. But it’s quietly compounding in the background of your life, and the difference between intentional stewardship and benign neglect may be six figures over a career.

You wouldn’t leave your weapon unattended. You wouldn’t skip a pre-combat inspection. Your retirement account deserves the same level of attention.

Don’t let your TSP manage you. Manage your TSP.
