Yield is trailing 12-month distributions divided by the latest price, calculated the same way for every fund, as of October 30, 2026. Distributions, prices, and fees change; confirm with the issuer before investing. Highlighted cells show the higher yield, lower fee, larger fund, or higher return, which is not the same as the better fund for you.
You already use Vanguard, or you want slightly broader coverage from the float-adjusted index.
You already use iShares, or you want the older fund, which launched in 2003.
The returns of these two funds differ by hundredths of a percent. More important decisions are how much of your portfolio belongs in bonds, and whether you need cash-like T-bills or more yield from corporate bonds. Interest is taxed as ordinary income, so these funds are often held in retirement accounts.
Neither in any meaningful way. Use whichever fits your brokerage.
The figure covers the whole Vanguard fund, including its mutual fund share classes, not just the ETF.
