I’ve got a Schwab account and some cash I don’t plan on using for a while, so I bought $100k worth of T-Bills that mature in 3 months with a 4.6% rate.
Am I right in thinking I’ll earn $4600 after 3 months, or is it more like $1150 since 4.6% is the annual rate? Does the money just show up in my account when it matures? I feel like I’m messing up this math.
Here’s how T-Bills actually work. You buy them at a discount and get the full face value when they mature. In your case, you’ll pay about $98,870 for $100k in T-Bills, and after 3 months you’ll get back $100k. So the interest is around $1130.
Longer-term Treasury bonds pay interest periodically, but T-Bills don’t.
4.6% divided by 365 days, multiplied by 90 days (3 months), gives you about 1.13% for the quarter.
Is this $100k an emergency fund or for something else? If not, you might want to invest it. If it’s more of an emergency stash, you could consider something like SGOV, which is a Treasury ETF.
It’s not an emergency fund, just extra cash I’m parking short-term. Earning 1.13% is better than nothing, though not as high as stock market gains in 3 months—of course, that’s a risk. I’ve got separate funds for stocks and ETFs.

Yep, stocks can give you big returns sometimes, but they’re not guaranteed. With T-Bills, you’re getting a guaranteed return, even if it’s smaller. Earning 5% a year without risk is pretty solid.
Just so you know, when buying on the secondary market (like through Schwab), it doesn’t matter what type of Treasury it is. If there’s 3 months left, it’ll trade and return the same whether it was originally a 20-year or a 3-month T-Bill.
You can actually buy T-Bills for as short as a week with Schwab. You just need to adjust the search date settings to the current and next month. I’ve done it before when I needed to park money for a week.
Funny enough, the super-short ones often have higher yields but don’t lock you in for months or years.
I didn’t realize that—I should have adjusted the search date! I just went with 3 months, but I don’t see myself needing the cash soon. Maybe I’ll go for the 1-week or 4-week next time and roll it over.
