Definition
Tax-Equivalent Yield is a financial metric used to compare the yield on a taxable bond to the yield on a tax-free municipal bond. It provides investors with a standardized method to determine how much a taxable bond would need to yield before taxes to equal the after-tax yield of a tax-exempt bond in their particular tax bracket.
Calculation
The formula for calculating the Tax-Equivalent Yield (TEY) is:
\[TEY = \frac{{\text{Tax-Free Yield}}}{{1 - \text{Marginal Tax Rate}}}\]
Where:
- Tax-Free Yield is the yield on the municipal bond.
- Marginal Tax Rate is the tax rate applicable to the investor’s income bracket.
Example
Suppose an investor is considering purchasing a tax-free municipal bond offering a 3% yield. The investor’s marginal tax bracket is 30%. The tax-equivalent yield would be calculated as follows:
\[TEY = \frac{0.03}{1 - 0.30} = \frac{0.03}{0.70} = 0.0429 \text{ or } 4.29%\]
This means a taxable bond must yield 4.29% to provide the same after-tax return as a municipal bond yielding 3% for an investor in a 30% tax bracket.
Frequently Asked Questions
What is the purpose of calculating Tax-Equivalent Yield?
The purpose is to compare the true yields of taxable and tax-exempt bonds to determine which investment is more advantageous after accounting for taxes.
How does my tax bracket affect the Tax-Equivalent Yield?
The higher your marginal tax bracket, the higher the Tax-Equivalent Yield will be, making tax-free bonds more attractive.
Is Tax-Equivalent Yield applicable only to municipal bonds?
No, while it is commonly used for municipal bonds, this concept can be applied to any tax-exempt income.
Are there any risks associated with bonds that I should be aware of?
Yes, bonds can be subject to interest rate risk, credit risk, and market risk, which could affect their price and yield.
What is a marginal tax bracket?
A marginal tax bracket is the tax rate that applies to the last dollar of taxable income. It determines the fraction of additional earnings that must be paid in taxes.
- Bond Yield: The interest or dividend income earned on a bond, expressed as a percentage of the bond’s current price.
- Municipal Bond: A debt security issued by a state, municipality, or county to fund public projects, often exempt from federal taxes.
- Marginal Tax Rate: The rate at which the last dollar of income is taxed, which impacts an investor’s decisions on taxable versus tax-exempt investments.
- Pretax Yield: The yield on an investment before taxes are considered.

### What is the main use of calculating Tax-Equivalent Yield?
- [ ] Assessing the risk level of bonds
- [x] Comparing the yield of taxable and tax-exempt bonds
- [ ] Estimating future interest rate changes
- [ ] Determining annual portfolio returns
> **Explanation:** The main purpose of calculating Tax-Equivalent Yield is to compare the yields of taxable and tax-exempt bonds to understand their true financial benefits considering taxes.
### What is the formula for Tax-Equivalent Yield?
- [x] \\(\frac{{\text{Tax-Free Yield}}}{{1 - \text{Marginal Tax Rate}}}\\)
- [ ] \\(\text{Tax-Free Yield} \times (1 - \text{Marginal Tax Rate})\\)
- [ ] \\(\frac{1}{\text{Tax-Free Yield}} - \text{Marginal Tax Rate}\\)
- [ ] \\(\text{Tax-Free Yield} + \text{Marginal Tax Rate}\\)
> **Explanation:** The Tax-Equivalent Yield formula is \\(\frac{{\text{Tax-Free Yield}}}{{1 - \text{Marginal Tax Rate}}}\\), which helps investors determine the pretax yield a taxable bond would need to equal the tax-free yield.
### If a municipal bond has a yield of 2% and an investor is in a 25% tax bracket, what is the Tax-Equivalent Yield?
- [ ] 2.00%
- [ ] 2.25%
- [ ] 2.50%
- [x] 2.67%
> **Explanation:** Using the formula \\(\frac{0.02}{1 - 0.25} = 0.02 / 0.75 = 0.0267\\) or 2.67%, shows that the equivalent taxable yield is 2.67% for an investor in a 25% tax bracket.
### What does the marginal tax bracket represent for an investor calculating Tax-Equivalent Yield?
- [ ] Total taxable income
- [ ] Standard deduction
- [x] Tax rate on the last dollar of income
- [ ] Average tax rate
> **Explanation:** The marginal tax bracket represents the rate at which the highest portion of an investor's income is taxed, crucial for calculating true comparative yields.
### Which type of investments commonly utilize Tax-Equivalent Yield calculations?
- [ ] Corporate bonds
- [x] Municipal bonds
- [ ] Savings accounts
- [ ] Real estate
> **Explanation:** Municipal bonds, which are often tax-exempt, commonly use Tax-Equivalent Yield calculations to compare their yield effectively against taxable bonds.
### If an investor's marginal tax rate increases, what happens to the Tax-Equivalent Yield?
- [x] It increases
- [ ] It decreases
- [ ] It remains the same
- [ ] It is unaffected
> **Explanation:** As the marginal tax rate increases, the Tax-Equivalent Yield also increases due to the greater tax benefit offered by the tax-free bond.
### Why is Tax-Equivalent Yield particularly useful for high-income investors?
- [ ] It simplifies interest calculations.
- [x] It highlights tax benefits of municipal bonds.
- [ ] It reduces portfolio complexity.
- [ ] It avoids the need for diversification.
> **Explanation:** High-income investors benefit significantly from tax-exempt municipal bonds, and Tax-Equivalent Yield helps them understand these benefits compared to taxable bonds.
### For an investor in the 40% tax bracket, what is the Tax-Equivalent Yield if the tax-free yield is 4%?
- [ ] 4.25%
- [ ] 5.00%
- [x] 6.67%
- [ ] 10.00%
> **Explanation:** Using the formula \\(\frac{0.04}{1 - 0.40} = \frac{0.04}{0.60} = 0.0667\\) or 6.67%, the equivalent yield if the investor is in the 40% tax bracket.
### Which of the following best describes a municipal bond?
- [x] A tax-exempt debt security issued by a government entity
- [ ] A federally taxable bond issued by a corporation
