The SEC yield and the distribution yield answer two different questions about the same fund. The SEC yield is a standardized, forward-looking estimate of the recurring income a fund is producing right now, net of expenses, over a 30-day snapshot. The distribution yield is a backward-looking tally of every dollar the fund actually paid out to shareholders over the past 12 months, divided by today’s share price. When you compare SEC yield vs distribution yield, the SEC number is the cleaner tool for choosing between funds, and the distribution number is the honest record of what already landed in your account, sometimes padded by capital gains or a return of your own principal.
What the SEC Yield Actually Tells You
The SEC yield exists so that funds advertising a yield have to calculate it the same way. The Securities and Exchange Commission does not require any fund to publish a yield, but a fund that chooses to advertise one must use the SEC’s uniform formula and pair it with standardized total return figures and the usual disclaimer about past performance.1U.S. Securities and Exchange Commission. SEC Yield for Funds That Invest Significantly in TIPS
The number looks at net investment income — interest and dividends from the fund’s holdings, minus the fund’s operating expenses — over a trailing 30-day period, then annualizes it as a percentage of the fund’s maximum offering price on the last day of that period.2U.S. Securities and Exchange Commission. Form N-1A Capital gains, realized or unrealized, are excluded on purpose. That exclusion is the whole point of the metric: it isolates recurring income and strips out one-time windfalls.
For bond funds, the SEC yield also amortizes premiums and accretes discounts on the bonds the fund holds. A bond bought above face value has that premium gradually written down, reducing reported income; a bond bought at a discount sees its discount added back, raising reported income. This makes the SEC yield closer to a yield-to-maturity measure than a simple average of coupon rates, so it reflects the income you can realistically expect as bonds in the portfolio move toward maturity.
Because expenses come out of the numerator, the SEC yield is always net of the fund’s expense ratio. Two funds holding the same bonds but charging different fees will report different SEC yields, and the cheaper fund will win. That built-in fee sensitivity is one reason the metric works well for side-by-side shopping.
Watch for Subsidized Yields
Many fund sponsors temporarily waive part of their management fee or reimburse certain expenses, especially on newer funds. The SEC yield published during a waiver period is a “subsidized” yield and looks higher than what the same fund would report without the waiver. Some fund companies publish both a subsidized and an unsubsidized figure. If you build a long-term income plan around a subsidized number and the waiver expires, the yield you actually receive will drop. Check the prospectus or fact sheet for language about fee waivers and their expiration dates before you commit.
What the Distribution Yield Actually Tells You
The distribution yield sums every cash payment the fund made to shareholders over the past 12 months and divides by the current share price. It answers a simpler question: what did this fund pay out last year relative to what a share costs today?
Unlike the SEC yield, the distribution yield is not standardized. Different fund companies and data providers calculate it differently. Some include every distribution in the numerator — income dividends, short-term capital gains, and long-term capital gains. Others strip out capital gains and count only income dividends. Schwab Asset Management, for example, excludes all capital gains from its trailing distribution yield, while other issuers include them. If you’re comparing distribution yields across providers, confirm what each number includes before you trust the comparison.
Capital gains distributions are the biggest reason a distribution yield can tower over the SEC yield on the same fund. An actively managed equity fund that sold appreciated stocks during a strong year may distribute large long-term capital gains at year-end. Those gains inflate the trailing 12-month payout, but they say almost nothing about what the fund will pay next year. A high distribution yield fueled by capital gains reflects portfolio turnover and favorable markets, not durable income.
Return of Capital Is Not Income
Some funds also pay distributions that include a return of capital, which is your own invested money being handed back to you. Return of capital is generally not taxable when you receive it, but it reduces your cost basis in the fund. Once your basis reaches zero, any further return-of-capital distributions become taxable as capital gains.3Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions A distribution yield propped up by return of capital is a slow liquidation of your investment dressed up as income.
Why the Two Yields Diverge
The gap between a fund’s SEC yield and its distribution yield is a signal worth reading. When the two numbers sit close together, most of the payouts are coming from genuine investment income. When the distribution yield sits well above the SEC yield, something else is driving the cash.
The usual culprits are large realized capital gains and return of capital. A fund might show a 2% SEC yield and a 5% distribution yield, with the three-point gap coming from a single year-end capital gains payout. That gap warns anyone counting on the higher figure to keep coming. The SEC yield is the better predictor of next year’s income. The distribution yield is a receipt for last year’s cash flow.
Actively managed equity funds and high-turnover sector ETFs tend to show the widest divergence. Index funds and buy-and-hold bond funds tend to show narrower gaps because they realize fewer capital gains. If you’re comparing two bond funds in the same category and one shows a distribution yield far above its SEC yield, look at the annual report before assuming you’ve found extra income.
Section 19(a) Notices Show Where the Money Came From
When a fund’s distribution includes anything other than net investment income, federal law requires the fund to send shareholders a written notice breaking down the sources. The requirement comes from Section 19(a) of the Investment Company Act of 1940 and its implementing rule.4eCFR. 17 CFR 270.19a-1 – Written Statement to Accompany Dividend Payments by Management Companies
Each notice specifies how much of the per-share distribution came from net investment income, short-term capital gains, long-term capital gains, and return of capital, along with cumulative year-to-date figures from each source. These are estimates that can shift by year-end, but they give you an early read on whether a generous payout is actually sustainable. If you own a fund whose distribution yield sits well above its SEC yield, the Section 19(a) notice is where the truth lives. Most fund companies post them on their websites alongside distribution announcements.
Yield Percentages Hide Tax Character
A single yield number tells you almost nothing about your after-tax return, because the components of a fund’s distributions are taxed very differently.
- Ordinary income from interest and non-qualified dividends is taxed at your marginal federal income tax rate, which can reach 37% for top earners in 2026.
- Qualified dividends are taxed at the preferential long-term capital gains rates of 0%, 15%, or 20%, depending on taxable income. To qualify, you generally must hold the dividend-paying shares for at least 61 days during the 121-day period around the ex-dividend date.
- Long-term capital gains are also taxed at 0%, 15%, or 20%. For 2026, the 20% rate begins at $545,500 of taxable income for single filers and $613,700 for married couples filing jointly.5Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed
- Short-term capital gains are taxed as ordinary income at your marginal rate.
- Return of capital is not taxed when received, but it reduces your cost basis, which means a bigger taxable gain (or smaller loss) when you eventually sell.3Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions
A fund with a lower SEC yield but distributions weighted toward qualified dividends and long-term gains can deliver a better after-tax result than a fund with a higher SEC yield built on ordinary interest income. The Form 1099-DIV you receive each January breaks out the tax character of the prior year’s distributions.
Money Market Funds Use a 7-Day Yield Instead
Money market funds work on a different convention. Their holdings are ultra-short-term instruments that mature and roll over constantly, so a 30-day window is longer than the portfolio needs. The industry standard is the 7-day yield, which measures the fund’s average net income over the prior seven calendar days and annualizes it.6SEC.gov. Final Rule: Money Market Fund Reforms
You’ll often see two versions: a 7-day net yield (after expenses and any waivers) and a 7-day gross yield (before expenses). The net figure is the one that matches your actual return. When shopping for a money market fund, compare 7-day net yields rather than SEC 30-day yields.
TIPS Funds Break the Apples-to-Apples Promise
Treasury Inflation-Protected Securities adjust their principal upward with inflation, and the SEC yield formula predates them. Some TIPS funds treat the inflation adjustment to principal as income when calculating SEC yield; others exclude it. During periods of rising inflation, a fund that includes the adjustment will report a noticeably higher SEC yield than a competitor that excludes it, even when the two hold virtually identical bonds.1U.S. Securities and Exchange Commission. SEC Yield for Funds That Invest Significantly in TIPS
SEC staff has indicated it will not object if a TIPS fund uses a 12-month lookback for the inflation adjustment instead of the standard 30-day window, provided the fund discloses the approach.1U.S. Securities and Exchange Commission. SEC Yield for Funds That Invest Significantly in TIPS Check the footnotes on any TIPS fund yield before treating it as directly comparable to another.
Which Number to Rely On
Use the SEC yield when you’re shopping. For any two funds in the same category, it’s the cleaner metric: standardized formula, capital gains excluded, expenses subtracted. The fund with the higher SEC yield is producing more net investment income per dollar invested.
Use the distribution yield when you’re budgeting. A retiree drawing income needs to know what actually hit the account over the past 12 months, and the distribution yield answers that. It should not be the end of the analysis. If a large share of those distributions came from capital gains or return of capital, plan for lower payouts in years when those sources don’t repeat.
When the distribution yield sits well above the SEC yield, treat the gap as a prompt to investigate, not a reason to celebrate. Pull up the fund’s Section 19(a) notices or year-end tax reporting and see where the payouts came from. A durable income plan is built on the SEC yield; anything extra in the distribution yield is a bonus that may or may not show up again.
