ParkYourCash

Savings accounts, T-bills, Treasury ETFs and money market funds in one table, ranked by what you actually keep after tax.

Your tax rates:
Rough estimate: taxable interest is cut by federal + state rate; state-tax-exempt (Treasury) income only by the federal rate. Money funds that are only partly state-exempt are treated as fully taxable (conservative). Ignores deductibility of state tax, NIIT, and local taxes. Not tax advice.
