Choose how deeply to explain Tax-equivalent yield
Tax-equivalent yield: Convert a tax-exempt investment yield into the taxable yield needed to match it.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Tax-equivalent yield to answer this question: convert a tax-exempt investment yield into the taxable yield needed to match it? Enter Tax-exempt yield and Marginal tax rate; the calculator shows Tax-equivalent yield. Try changing one number and watch what happens to Tax-equivalent yield. The answer tells you Tax-equivalent yield.
Age 15Explain it to a 15-year-oldConnect it to the formula
The comparison assumes the stated income is fully exempt and the entered marginal rate applies; jurisdiction rules differ. The rule is Tax-equivalent yield = tax-exempt yield ÷ (1 − marginal tax rate). Its input values are Tax-exempt yield (%), Marginal tax rate (%), and the main result is Tax-equivalent yield. Try changing one number and watch what happens to Tax-equivalent yield.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a personal-finance model from stated cash amounts, rates and time assumptions. The implemented relation is Tax-equivalent yield = tax-exempt yield ÷ (1 − marginal tax rate), evaluated from Tax-exempt yield (%), Marginal tax rate (%) to produce Tax-equivalent yield. The comparison assumes the stated income is fully exempt and the entered marginal rate applies; jurisdiction rules differ. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
What this personal finance tool does
Convert a tax-exempt investment yield into the taxable yield needed to match it.
Why the relationship works
The comparison assumes the stated income is fully exempt and the entered marginal rate applies; jurisdiction rules differ.
The formula
Tax-equivalent yield = tax-exempt yield ÷ (1 − marginal tax rate)
Inputs and time periods
This model uses Tax-exempt yield, Marginal tax rate. Keep currencies and time periods consistent, and distinguish current known amounts from assumptions about future rates.
What the result means
The primary output is Tax-equivalent yield; supporting outputs include Tax-exempt yield, Yield uplift required. Compare scenarios by changing one input at a time.
Limits of this compact model
This educational calculator cannot predict markets or account for every tax, fee, legal rule, benefit, insurance policy or personal circumstance. Verify material decisions with current documents and qualified advice.
