equivalent taxable yield

The taxable return that must be achieved in order to equal, on an aftertax basis, a given tax-exempt return. Equivalent taxable yield is calculated by dividing the available tax-exempt yield by one minus the investor's marginal tax rate. For example, a tax-exempt return of 9% for an investor in a 40% marginal tax bracket would require a taxable return of ^.09/_0.6 , or 15%, to produce the same aftertax equivalent.

Does the purchase of tax-free securities make sense?

Analyze investments for risk related to return (payout and growth) and yield. Tax-free securities have less risk, but their return is usually lower than riskier growth investments, corporate bonds, or preferred stocks. Determine the equivalent taxable yield of a tax-free security (yield divided by the difference of one minus your marginal tax bracket). Compare the investment to alternative securities with similar or higher yields or returns. Invest for a higher return if you are comfortable with the risk. Tax-free securities make sense for high-income taxpayers looking for safer, certain returns.

Equivalent taxable yield. While taxable bonds normally pay higher interest rates than tax-exempt bonds, they sometimes provide a lower overall yield.

Finding the equivalent taxable yield lets you determine the minimum interest rate a taxable bond must pay to equal the yield of a comparable tax-exempt bond. The formula for the equivalent taxable yield is tax-exempt interest rate ÷ (100 - your tax rate).

So, for example, if a municipal bond pays an annual interest rate of 7%, and your tax rate is 35%, the equivalent taxable yield would be 7 ÷ (100 - 35) = 10.8%. That means that in order to be as attractive an investment as the 7% municipal bond, a taxable bond would need to pay an annual interest rate of 10.8% or more.
