Taxable Yield Equivalent: Calculating Your Investment's Tax Efficiency

Your taxable yield equivalent is a measure used to compare the after-tax yield of a tax-free investment with the yield of a taxable investment. This metric helps you assess the tax efficiency of your investments by considering the impact of taxes on your returns.

The formula to calculate the taxable yield equivalent is:

$\text{Taxable Yield Equivalent} = \frac{\text{Taxable Yield}}{(1 - \text{Tax Rate})}$

Here:

• Taxable Yield: The yield or interest rate of a taxable investment, such as a corporate bond or certificate of deposit.
• Tax Rate: Your marginal tax rate, representing the percentage of your income that you pay in taxes.

The purpose of this calculation is to adjust the taxable yield to account for the taxes you'll owe on the investment income. The adjustment is made by dividing the taxable yield by the complement of the tax rate (1 - Tax Rate).

Example:

Let's say you have a taxable investment with a yield of 6%, and your marginal tax rate is 30%. The taxable yield equivalent would be:

$\text{Taxable Yield Equivalent} = \frac{6\%}{1 - 0.30} = \frac{6\%}{0.70} = 8.57\%$

In this example, the taxable yield equivalent is 8.57%, meaning that a tax-free investment with a yield of 8.57% would provide a similar after-tax return as the taxable investment with a 6% yield.

Investors use the taxable yield equivalent to compare the attractiveness of tax-free and taxable investments, particularly in the context of fixed-income securities like bonds. Tax-free investments, such as municipal bonds, may offer lower pre-tax yields than taxable investments, but their after-tax returns can be more competitive for investors in higher tax brackets.

Keep in mind that this is a simplified calculation, and other factors such as investment risk, liquidity, and overall financial goals should also be considered when making investment decisions. Additionally, individual tax situations vary, so consulting with a financial advisor can provide personalized insights based on your specific circumstances.

ETY = Nominal yield / (1 - Tax rate)

ETY = 5% / (1 - 25%) = 6.67%
