SGOV vs Buying T-Bills Directly: Is the 0.09% Fee Worth It?

SGOV holds short-term US Treasury bills and charges 0.09% a year to do it. You could buy those same T-bills yourself, through a broker or TreasuryDirect, and pay no fund fee at all. So the obvious question: why pay anything for SGOV when the underlying asset is free to buy?

The honest answer is that the 0.09% is not really paying for the bills. It is paying for three things you would otherwise do by hand: automatic reinvestment, daily liquidity, and not having to think about it. For most people those are worth far more than the fee. For a few specific situations, buying direct genuinely wins. Here is how to tell which one you are.

What the 0.09% Actually Buys

When you buy a T-bill directly, you commit money for a fixed term (4, 8, 13, 26, or 52 weeks). When it matures, the cash lands in your account and sits there earning nothing until you manually buy the next one. To keep your money working, you build a "ladder" of bills maturing on a rolling schedule and reinvest each one as it comes due. That is real, ongoing work.

SGOV does that ladder for you, automatically, every day. It holds a rolling basket of 0 to 3 month Treasuries, reinvests maturing bills the moment they come due, and pays you the income monthly. You can sell any or all of it on any trading day and have cash the same day. There is no auction to schedule, no maturity to track, no idle cash between rungs.

Notice the row that often gets ignored: idle cash. If a direct T-bill matures and you do not reinvest it for a week, that money earns nothing for that week. Do that a few times a year and the "free" approach quietly gives back more than SGOV's 0.09% would have cost. The fee is the price of never having idle cash.

The Cost in Real Numbers

On a $50,000 position, SGOV's 0.09% fee is about $45 a year. Buying T-bills directly saves that $45. The question is whether your time and the risk of idle cash are worth $45 a year on $50,000. For most people managing their own ladder across multiple maturities, the answer is no. The fee is smaller than the value of the automation and the cost of a single missed reinvestment.

The math flips when the balance gets large. On $1,000,000, that same 0.09% is $900 a year. At that size, a buy-and-hold investor who is comfortable laddering Treasuries and holding them to maturity can save a meaningful amount by going direct, because the fee scales with the balance while the work does not.

One Thing Both Get Right: State Taxes

Both SGOV and direct T-bills hold US Treasury securities, and Treasury income is generally exempt from state and local income tax. That is a real edge over a bank savings account or a prime money market fund that holds non-Treasury paper, especially if you live in a high-tax state like California or New York. Whether you buy the ETF or the bills, you keep that state-tax exemption. This is general information, not tax advice, so confirm your own situation.

The Short Version

• SGOV holds the same T-bills you could buy yourself and charges 0.09%, about $45 a year per $50,000.
• The fee buys automatic reinvestment, daily liquidity, and no idle cash between maturities.
• For most cash holders, that automation is worth more than the fee. SGOV is the simple default.
• Buying direct wins for very large balances, where 0.09% becomes real money, or when you want a bill held to a specific maturity date.
• Both keep the state-tax exemption on Treasury income.

Common Questions

Is SGOV worth it compared to buying T-bills directly?

For most investors parking cash, yes. SGOV charges 0.09% a year, but that fee buys automatic reinvestment, same-day liquidity, and zero idle cash between maturities. Buying T-bills directly avoids the fee, but you have to build and roll a ladder of bills yourself, and any cash that sits uninvested between maturities earns nothing. For a typical cash holder, that automation is worth more than the fee. Buying direct wins mainly for very large balances or when you specifically want a bill held to a known maturity date.

How much does SGOV's fee cost versus buying T-bills directly?

On a $50,000 position, SGOV's 0.09% fee is about $45 a year, which is what you save by buying T-bills directly. On $1,000,000, that same 0.09% is about $900 a year. The fee scales with your balance while the work of managing a ladder does not, so the larger the balance, the stronger the case for buying direct. For most people the automation and the avoided cost of a single missed reinvestment are worth more than $45 a year.

When should I buy Treasury bills directly instead of SGOV?

Two situations. First, very large balances, where 0.09% becomes real money: $900 a year on $1,000,000 is worth the effort for an investor comfortable laddering Treasuries. Second, when you want a bill held to a specific maturity date with a known, locked payout, which direct bills give you and an ever-rolling ETF does not. If you want a hands-off cash holding, SGOV is the simpler default.

Is SGOV income exempt from state taxes like T-bills?

Yes. Both SGOV and direct Treasury bills hold US Treasury securities, and Treasury income is generally exempt from state and local income tax. You keep that exemption whether you own the ETF or the bills themselves. It is a real advantage over a bank savings account or a prime money market fund that holds non-Treasury paper, especially in a high-tax state.
