Investors and fund managers often look for transparent, standardized ways to measure the income-generating performance of mutual funds and exchange-traded funds (ETFs). One of the most reliable metrics used in the finance industry is the 30-day SEC yield. Our 30-Day SEC Yield Calculator is designed to simplify this process and provide you with accurate, easy-to-understand results in just seconds.
This tool helps you determine the standardized yield for a bond fund or ETF, enabling you to evaluate its profitability while accounting for interest income, dividends, and related expenses.
🔎 What is 30-Day SEC Yield?
The 30-day SEC yield is a standardized yield calculation created by the U.S. Securities and Exchange Commission (SEC). It represents the annualized income earned by a fund over a recent 30-day period, after deducting expenses, and is expressed as a percentage of the fund’s current share price.
This yield is useful for comparing bond and income fund performance across different issuers. It provides investors with a fair view of a fund’s yield without the distortion of temporary income spikes or unrealized capital gains.

📘 Formula Used for 30-Day SEC Yield
The calculation uses the following formula:
mathematicaCopyEditSEC Yield = 2 × [(Interest and Dividends – Accrued Expenses) ÷ (Outstanding Shares × Max Price Per Share) + 1]^6 – 1
In simple text:
- Subtract accrued expenses from interest and dividends.
- Divide the result by the product of outstanding shares and maximum price per share.
- Add 1 to the quotient.
- Raise the result to the 6th power.
- Subtract 1 from it.
- Multiply the entire outcome by 2.
This formula effectively annualizes a monthly yield by compounding it over 6 months and then doubling it, thus aligning with a 12-month period.
📊 Example Calculation
Let’s look at a simple example:
- Interest and Dividends: £12,000
- Accrued Expenses: £2,000
- Outstanding Shares: 5,000
- Max Price Per Share: £20
Step-by-step:
- Interest and Dividends – Accrued Expenses = 12,000 – 2,000 = 10,000
- Outstanding Shares × Max Price Per Share = 5,000 × 20 = 100,000
- 10,000 ÷ 100,000 = 0.1
- 0.1 + 1 = 1.1
- 1.1 raised to the 6th power ≈ 1.771561
- 1.771561 – 1 = 0.771561
- 0.771561 × 2 = 1.543122
Result: The 30-day SEC Yield is 1.54 (or 154.31%)
This indicates a highly profitable scenario, although actual values typically range between 1% and 10% for most bond funds.
💡 Why Is SEC Yield Important?

It gives a real view of what an investor earns after fees. - Predicts Income Potential:
