If you cannot find a specific rate on the chart you can compare yields by using the following formula:

Taxable equivalent yield = tax-free yield ÷ (100% - marginal tax bracket %)

Example: Assume you are in the 25% tax bracket, and have an account with a 4.5% tax-free yield. To get the equivalent taxable yield, divide 4.5% by 75% (100% - 25%). The taxable yield is 6.%.
