You can compare yields by using the following formula:

Taxable equivalent yield = tax-free yield ÷ (100% - marginal tax bracket %) or see www.calcxml.com/calculators/inc11?skn, which includes both federal and state income tax rates.

Example: Assume you are in the 22% tax bracket, and have an account with a 4.0% tax-free yield. To get the equivalent taxable yield, divide 4.0% by 78% (100% - 22%). The taxable yield is 5.13%.
