Ah ok 4.4% seems more reasonable. So assuming $100,000 worth of bonds, you get $4,400 in interest a year?
Approximately, yes.
It's a bond fund, so it owns a collection of bonds. VBTLX probably owns hundreds or thousands. The interest received will vary a bit as interest rates overall fluctuate and as the bonds in the portfolio mature (reach the end of the loan term) or are sold.
Also of note is that interest from US government obligations is often state income tax free (it is in my state), so that helps a bit. For details on this, check with your tax preparer.
Great. That definitely helps, thank you for explaining it. Does not seem to be much more appealing than just holding cash in a high yield savings account (at least in our current times with the high interest rates that are offered) since one cannot expect price appreciation to be a big factor when holding bonds, as opposed to holding stocks.
No worries.
A HYSA will have interest rate risk - if or when the Federal Reserve lowers interest rates, the bank will soon lower the HYSA interest rate. At the same time, a fund like VBTLX (or any bond fund with intermediate or long duration) will see price appreciation because its yield will look comparatively better than it does now.
I'm not a super expert on these kinds of investments, but it does seem to me that investing in this area boils down to buying now what you think will do well in the future...without knowing what the future holds. Predicting interest rate changes and timing is, IMHO, impossible, although there are several folks here on this board who try to do it anyway.
Since I don't think I can predict (at least not better than the Vanguard computers), I just invest in VBTLX. Some family members who are in higher brackets invest in VWIUX due to it's tax characteristics.
