The average carried credit card balance in the U.S. is almost $16,000 per household. The average interest on that carried balance is 12.79% (source: Creditcards.com). The true cost of borrowing money is the sum of interest paid, plus the earnings foregone had that money been invested; this is what economists call "opportunity cost": the cost of the foregone opportunity to do things differently. For example, the true cost of a "Zero-percent interest!" auto loan is actually the earnings foregone had the money been invested, i.e., around 6.6%; and the true cost (the opportunity cost) of a carried balance on a credit card is the sum of the interest charged (12.79%) plus the earnings foregone (an average market return of 6.6%), or over 19%.
