Use Cases
Compare municipal bonds vs. taxable bonds
Determine whether a tax-free municipal bond or a taxable corporate bond offers a better after-tax return for your tax bracket.
Example: If a municipal bond yields 3% and your tax rate is 25%, the taxable equivalent yield is 4%.
Evaluate bond investments for your portfolio
Use the calculator to see if tax-exempt bonds are worth it compared to taxable alternatives, helping you make informed investment decisions.
Example: Compare a 2.5% tax-free yield with a 3.5% taxable bond at a 30% tax rate.
Frequently Asked Questions
- What is taxable equivalent yield?
- Taxable equivalent yield is the pre-tax yield a taxable investment must offer to match the after-tax return of a tax-exempt investment, given your marginal tax rate. It helps you compare municipal bonds with taxable bonds.
- How do I use this calculator?
- Enter the tax-exempt yield (as a percentage) and your marginal tax rate (as a percentage). The calculator will compute the taxable equivalent yield using the formula: tax-exempt yield divided by (1 minus tax rate).
- Why is marginal tax rate important?
- Your marginal tax rate determines how much of your taxable income is taken by taxes. A higher tax rate makes tax-exempt investments more attractive, increasing the taxable equivalent yield needed to match them.
Tips & Common Mistakes
Tips
- Use your marginal tax rate, not your effective tax rate, for the most accurate comparison.
- Remember that state and local taxes may also affect your tax-exempt yield; consider your total tax situation.
- Check if the tax-exempt bond is subject to alternative minimum tax (AMT) before relying solely on the calculation.
- Re-calculate if your tax bracket changes, as the equivalent yield will shift.
Common Mistakes to Avoid
- Using your effective tax rate instead of your marginal tax rate, which can understate the taxable equivalent yield.
- Forgetting to convert percentages to decimals when doing manual calculations (the calculator handles this for you).
- Ignoring that some tax-exempt bonds may be subject to state taxes, which can affect the true comparison.
