Tax Equivalent Yield Calculator
Our tax equivalent yield calculator can help you to calculate the bond yield of tax-free municipal bond investment.

What Tax Equivalent Yield Calculator does
The Tax Equivalent Yield Calculator on Omni Calculator helps users determine the taxable-equivalent yield of a tax-free municipal bond. By inputting the bond's interest rate and the user's marginal income tax rate, the tool computes the yield a comparable taxable investment would need to produce to match the after-tax return of the municipal bond. This allows investors to directly compare the true earning potential of tax-free bonds against taxable alternatives, simplifying investment decisions. The calculator also provides educational context, explaining the concept of tax equivalent yield and offering examples to help users interpret the results in the context of their personal tax situation.

Tax Equivalent Yield Calculator FAQ
- How is tax equivalent yield calculated?
- The calculator multiplies the bond's interest rate by the factor of one minus the marginal tax rate, then divides by that same factor to find the yield a taxable investment would need to match the after-tax return.
- Can I use this calculator for bonds other than municipal bonds?
- The tool is designed for tax-free municipal bonds, but the same principle applies to any tax-advantaged security; you would input the bond's yield and your tax rate to find the equivalent taxable yield.
- What if I don't know my marginal tax rate?
- You can estimate it based on your federal and state income tax brackets; the calculator will show how different tax rates affect the equivalent yield.
- Does the calculator consider compounding or bond maturity?
- No, the calculator uses a simple formula based on the interest rate and tax rate; it does not factor in compounding frequency or the bond's maturity date.
