Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

My financial advisor recommended the exact same approach. Nice to see it validated with actual numbers.
