Three Credit Cards, One Budget: What Order to Pay Them

Two cards is a nuisance. Three or more and the arithmetic stops being obvious, because every dollar you put on one card is a dollar not sitting on another. Order matters more than most people expect, and the difference runs to hundreds rather than pennies.

The same $9,000, three different plans

Take a realistic set. Card A holds $4,200 at 24.99 percent, Card B holds $3,100 at 19.9 percent, and Card C holds $1,700 at 14.5 percent. Minimum payments at 2 percent of the balance come to $84, $62 and $34, so $180 a month before anything else. Suppose you can find $400 a month in total, leaving $220 of spare cash to aim somewhere.

Highest rate first clears everything in 29 months and costs $2,353 in interest. Smallest balance first takes 30 months and costs $2,888. Dividing the $220 evenly across all three cards takes 30 months and costs $2,720. Same money, same start date, $535 between the best and worst version.

Why minimums alone go nowhere

Card A charges 24.99 percent a year, which is 2.08 percent a month, or $87 on a $4,200 balance in the first month. The minimum payment is 2 percent, or $84. Pay only the minimum and the balance is larger in month two than it was in month one. That is not hidden in the small print, it is two percentages sitting the wrong way round. The minimum payment trap shows what that looks like stretched over years.

When smallest balance first is the better plan

Highest rate first wins on paper every time. That is arithmetic, not opinion. But the gap here was $535 spread over more than two years, and plenty of people give up long before month 29.

On this budget, throwing the spare $220 at Card C clears it in about seven months and frees up its $34 minimum, which then joins the pile. One fewer statement, one fewer due date. If that is what keeps you paying, $535 is a fair price for finishing. Pick the plan you will actually complete rather than the one that wins by a nose in a spreadsheet.

Balance transfers change the numbers, not the method

Moving the $4,200 from Card A to a 0 percent offer with a 3 percent fee costs $126 up front. Against roughly $700 of interest that card generates in its first year at 24.99 percent, it is worth doing if you can clear it inside the promotional window. Miss the window and the rate waiting on the other side is usually worse than the one you left. A consolidation loan works the same way: it changes the rate, not the discipline.

How to set this up in the calculator

The credit cards payoff calculator wants one row per card: balance, APR and minimum payment. All three are on the statement. The balance you want is what you currently owe, not the credit limit, and the APR you want is the purchase APR, which is usually lower than the cash advance APR printed beside it.

Then enter your total monthly budget. That means everything going to cards combined, not the extra on top of minimums, because the calculator subtracts the minimums itself. Getting this wrong is the most common input error here.

Run it twice. Set the strategy to highest interest first and note the payoff month and total interest, then switch to smallest balance first and note both again. Those two totals side by side are the actual decision. Rerun it whenever a rate moves or you put something new on a card, because a single $600 purchase on Card A adds about six weeks to the plan.

Common questions

Should I close a card once it is paid off? Usually not straight away. Closing it removes that credit limit from your total, which pushes your utilisation percentage up on the balances still outstanding. If the card carries an annual fee, that changes the sum.

Does paying twice a month help? A little. Interest is normally worked out on the average daily balance, so a payment on the 10th reduces the balance for the remaining 20 days of the cycle. On $4,200 the saving is a few dollars a month, which is real but nothing like the effect of payment order.

What if the minimums use up my whole budget? Then payment order is not the problem to solve. Ask each issuer what hardship or reduced rate programmes exist, since they generally prefer a lower rate to a default, and check whether consolidating at a fixed rate cuts the monthly total.

Should I clear the cards before saving anything? Build a small buffer first, something like $1,000. Without it, the next unexpected bill goes back onto a card at 25 percent and undoes months of work.
