- Reflects annualized net income over past 30 days.
- Excludes capital gains and actual distributions.
- Enables easy comparison across similar funds.
What is SEC Yield?
The SEC Yield, mandated by the U.S. Securities and Exchange Commission, is a standardized measure of a bond fund's annualized net investment income over a recent 30-day period, expressed as a percentage of its maximum offering price per share. This yield provides a consistent way to compare bond funds by reflecting income after expenses, excluding capital gains or losses.
Unlike actual distributions, SEC Yield uses a hypothetical calculation that helps investors evaluate the income-generating potential of fixed income investments, including those found in bond ETFs.
Key Characteristics
SEC Yield offers a standardized, comparable figure across funds with these main features:
- Standardization: Uses a uniform formula that accounts for income and expenses over 30 days, enabling apples-to-apples fund comparisons.
- Excludes Capital Gains: Focuses solely on income, ignoring realized or unrealized capital gains and losses.
- Annualized Percentage: Converts monthly income into an annual rate, expressed as a percentage of the fund’s offering price.
- Relevant for Bond Funds: Primarily applies to bond and money market funds, with a 7-day variant common for the latter.
- Expense Adjusted: Reflects net income after deducting fund expenses, providing a realistic yield estimate.
How It Works
SEC Yield is calculated by annualizing the net investment income earned during a 30-day period, adjusting for fund expenses and the fund’s maximum share price. This involves a formula that compounds the income semi-annually to approximate yield to maturity or current income in bond portfolios.
The calculation excludes capital gains distributions and actual shareholder payments, focusing instead on income earned to provide a uniform benchmark. This makes it easier for investors to compare funds with differing distribution policies or trading strategies.

Examples and Use Cases
SEC Yield is widely used by investors seeking to assess income potential in fixed income investments. Here are some practical examples:
- Bond ETFs: Funds tracking corporate or municipal bonds often report SEC Yield to indicate expected income, found in many best bond ETFs.
- Money Market Funds: Use a 7-day SEC Yield variant to standardize short-term income metrics.
- Corporate Issuers: Although not directly linked to SEC Yield, companies like Delta and American Airlines impact bond market yields through credit risk, affecting fund yields.
- Dividend ETFs: While focused on dividends rather than bond income, dividend ETFs provide a useful contrast in income investment strategies.
Important Considerations
While SEC Yield is a useful tool, be mindful that it does not predict future returns or total fund performance due to market fluctuations and changing interest rates. It also excludes capital gains, which may be significant in some funds.
Investors should evaluate SEC Yield alongside other metrics, such as yield curves represented by the par yield curve, and consider fund expense waivers or reimbursements that can temporarily inflate reported yields. Balancing yield insights with company fundamentals, including earnings, can improve your income investment decisions.
Final Words
SEC Yield offers a clear, standardized snapshot of a bond fund's recent income performance, excluding capital gains and distributions. To make informed investment decisions, compare SEC Yields across similar funds while considering your income needs and risk tolerance.
Frequently Asked Questions
SEC Yield is a standardized measure mandated by the U.S. Securities and Exchange Commission that approximates the annualized net investment income earned by a bond fund or similar fund over a 30-day period, after expenses. It is expressed as a percentage of the fund’s maximum offering price per share and helps investors compare yields across funds.
SEC Yield reflects a hypothetical annualized income over 30 days, net of expenses, and excludes capital gains or losses and actual shareholder distributions. Distribution yield, on the other hand, is based on the actual payouts to shareholders and includes capital gains or losses.
SEC Yield provides a uniform benchmark that allows investors to consistently compare the income potential of bond funds and money market funds without the distortion of non-recurring gains or losses. This standardization helps in making informed investment decisions.
The SEC 30-Day Yield is calculated using a formula that annualizes the net investment income earned over the past 30 days after subtracting expenses, divided by the average daily outstanding shares and the maximum offering price per share. This formula approximates a compound yield to standardize reporting.
No, SEC Yield does not predict future performance because bond prices and income can fluctuate. Instead, it offers a standardized snapshot of recent income generation to help compare funds consistently.
The 30-Day SEC Yield is used primarily for bond funds and reflects income over a 30-day period, while the 7-Day SEC Yield is a similar standardized yield calculated over 7 days, commonly used for money market funds. Both exclude capital gains and actual distributions.
SEC Yield is typically disclosed in a fund’s prospectus under the Statement of Additional Information (SAI). It is a required disclosure for bond funds and certain other funds regulated by the SEC.
