The Card Payment That Actually Ends the Debt
Interest is charged first and principal gets the leftovers. That single ordering explains why some payments run in place for years and others clear the balance in months.
On a $6,000 balance at 22.9% APR, $250 a month clears it in 2 yr 9 mo with $2,101 of interest — more than a quarter of everything paid goes to the bank.
A $6,000 balance at 22.9% APR accrues $115 of interest in the first month. Pay $250 and $115 buys the interest; the remaining $135 touches the balance. Pay $100 and the interest alone eats the payment — the balance grows, and no schedule exists at all.
That is the line the calculator draws when it says "never": a payment at or below the first month's interest is not a slow plan, it is a plan that does not exist.
What $100 more a month does
Raise the payment from $250 to $350 and every extra dollar goes to principal — it never pays interest first. The payoff drops by roughly a year and the interest falls with it, because the balance that generates the interest shrinks faster.
This is why the payoff curve is steep rather than linear. The first dollars of any payment are spoken for; the dollars after them are pure progress. Shift the split and the end date moves by years, not weeks.
Two structural exits
Raising the payment works within the loan you have. Two moves change the loan itself: a balance-transfer card at 0% for a promotional window, which converts the compounding into a countdown for a one-time fee, and a fixed personal loan in the low teens, which trades the revolving structure for a schedule that ends.
Both fail the same way: a transfer with no repayment plan inside the window ends worse than staying put, because the deferred interest returns at the full rate. Either move is worth making only with the payment held fixed or raised — the structure buys time, the payment buys freedom.
Frequently asked questions
Should I pay the highest-rate card first?
Mathematically yes — it minimizes interest. Psychologically, clearing the smallest balance first keeps the plan alive. Either works if the total payment never falls when one card hits zero; the freed payment rolls onto the next card, not into spending.
Why does the calculator say "never" at exactly the interest amount?
A payment equal to the interest leaves the balance unchanged month after month — a schedule that never advances. The calculator reports it as never rather than showing a date that would never arrive.
Is the minimum payment designed to keep me in debt?
It is designed to keep the account performing, which is different and produces the same result: a minimum set near the interest keeps most of the payment buying interest for years. Enter your card's minimum into the calculator and the schedule it produces is the answer.
