Frequently asked questions

Because the balance falls as you pay it down. The interest is charged on a declining balance, so year one costs less than the APR suggests — but the total interest over the life of the debt is much larger.
If the monthly payment is less than balance × monthly rate, you never clear the debt — it grows. The calculator reports “Never clears” in that case.
Legally the APR must include most fees, but a separately charged annual fee is still real money. Enter it here so the first-year cost is complete.
