About TaxEquiv

TaxEquiv is a set of free calculators for the tax-equivalent yield (TEY) and for comparing municipal bonds against taxable bonds. Every tool runs entirely in your browser, so the numbers you type never leave your device.

The math — dividing a tax-exempt yield by one minus your combined marginal rate — is standard, published tax arithmetic that does not change, so the site stays correct without updates.

TaxEquiv is maintained by an independent maker. It may show non-intrusive advertising once traffic justifies it. We do not collect or sell your data.
