Pay down debt or invest

Paying down debt gives you a guaranteed, tax-free return equal to the loan's interest rate. Investing gives you an uncertain return, minus tax. See which side wins with your own numbers.

The investment return is an assumption; the interest saving isn't. So when the result is close, that favors paying down debt.

Die Erklärung dazu steht in der Lektion Expensive debt first.

Frequently asked questions

Why can't a debt payoff's return be compared directly to an investment return?

Because it's guaranteed and tax-free, while an investment return is uncertain and taxable.

What gross return would an investment need to beat an 8 percent loan?

At roughly 26 percent tax on investment income, about 10.8 percent, and guaranteed at that.
