This calculator effectively compares the long-term growth of keeping your money in a standard bank account versus investing it in the market. It does a nice job of factoring in the different tax treatments for ordinary interest and long-term capital gains. Keep in mind that while the description mentions IRAs, the math here specifically models a standard taxable brokerage account; if you use a tax-advantaged retirement account, your actual take-home will be higher. This remix adds meaningful new logic for modeling after-tax cash yields compared to the original mortgage calculator.
