Judge a debt payoff plan by the payment you can keep making, not the starting rate

The short answer

A lower rate is welcome, but it has to help you finish paying, not just make the next bill look easier. Julia starts with a payment she could keep making in an ordinary month, checked against her budget after essentials and other required obligations. A plan built on your best month can be hard to maintain.

Then she compares options at that same payment. In her example a $4,200 balance at 24% APR, paid at $273 a month, costs about $870 in interest. A balance transfer at 0% for 18 months with a 4% fee costs the $168 fee instead, a saving of roughly $702, but only if the balance is paid before the promotion ends. At a lower payment the answer changes.

Start with your statements

Get the details from your statements instead of relying on memory, because a rate or minimum may have changed. Write down each balance, APR, required minimum and due date, including any promotional expiration dates. With those in front of you, you can compare the cost of getting all the way to zero.

A balance transfer moves eligible debt to another account, sometimes with a promotional rate and an upfront fee. Julia considers it beside staying on her current card, using the same payment she can afford.

Staying put against a transfer

Julia's example uses a simplified 2% monthly rate and payments at month-end, with no new purchases, fees or rate changes. She owes $4,200 at 24% APR and can pay $273 a month.

• Staying put takes 19 payments, the last one smaller, and costs about $870 in interest.
• A transfer at 0% for 18 months from opening, with a 4% fee, adds a $168 fee and makes the new balance $4,368. Paying it over 16 months still takes $273 a month. The lower financing cost saves roughly $702.

She would need enough approved available credit for the qualifying debt, and the transfer would need to post early enough, so she counts the actual payment opportunities. Planning for 16 payments in an 18-month offer leaves a little room on the calendar. If everything goes as planned, the debt is paid before the promotion ends and the financing cost is the $168 fee. That appeals to her because she pays the same amount each month and loses less of it to financing.

If she can afford only $210 a month, she needs a different plan. Sixteen payments total $3,360, and she would still owe $1,008 at the planned finish date. The offer may still have time left. Recalculate using the actual dates and the APR after the promotion, and do not assume another transfer will be available when you need it. Another approval and a suitable offer are not certain.

Look at the options before moving the balance

Moving the balance does not solve whatever caused it to grow. If spending has been exceeding income, that needs attention alongside the transfer. Other options include a different promotional period, a personal loan with its fees included, an issuer hardship arrangement or a revised plan on the current card. Look at the total cost and at a payment you can afford, because a 0% headline cannot answer both questions for you.

Once you decide to transfer

Keep checking the old account until the payment actually arrives. An approval is the start of the move, not proof that the old bill is settled. While the transfer is processing, keep making required payments on the original account and check that the payment posts on both accounts. Look for residual interest, and check how the transfer fee affects available credit. Requesting a transfer is not completing one.

Confirm that the issuer accepts the debt, since transfers between accounts at the same institution may be excluded. Your approved limit might not cover the whole balance plus the fee. If only part transfers, budget for required payments on both accounts.

Keep new purchases separate from the debt you are clearing. The promotional rate does not automatically cover everything you put on the account. Purchases on the transfer card may have a different rate, and carrying the transfer balance can affect the purchase grace period. The whole account is not interest-free because one balance has a promotional rate.

Several debts, and room for ordinary bills

With several debts, first make sure you can cover every required minimum. Then choose where the extra payment helps most. If the rates stay fixed, paying extra toward the highest interest rate generally costs the least in interest. Revisit that order if rates, promotions or deadlines change. Clearing a smaller balance first may keep you motivated, which is a reasonable preference. It can cost more interest, so calculate the tradeoff and know what you are choosing. When one debt is paid, put its old payment toward the remaining debt.

Leave room for ordinary expenses that do not arrive on a convenient schedule. The right cash cushion depends on your situation, but you do not want to make an aggressive card payment and then borrow again for groceries a few days later. Include predictable bills that come once or twice a year. If an annual car-insurance bill is $720 and you have not allowed for it, set aside $60 a month before deciding how much extra can go to debt. That may make the planned card payment smaller, but it makes the plan more believable.

If even the minimums do not fit, ask for help promptly rather than agree to a payment you cannot sustain. Call the issuers and ask what hardship options are available. Get clear on the payment, rate, duration, fees, account restrictions and credit reporting before agreeing. A nonprofit credit counselor may help you consider a broader plan, especially when several debts are involved.

Before you act

Julia's Wallet Check for a payoff is cost, calendar and a payment she could keep making. She compares every option at that same affordable payment, including what happens after any promotion. That is also the idea behind the financing Wallet Score: repayment costs and practical terms matter more than shopping rewards.

Judge the plan by whether it reduces the debt at a cost and pace you can manage. A possible credit-score change is a separate consideration. A new application and account can affect your score, and paying down debt can too, but neither gives a certain number of points. Once the debt is paid, decide whether the account still helps. Available credit can matter, but so can fees or the temptation to borrow again.

Write down the cost of staying put, the transfer fee and the monthly payment you can keep making. Choose the offer only when the whole plan works, including what happens after the promotion. On the issuer's page, check the promotional period and when it starts, the transfer fee, whether the transfer window and your available credit fit the balance, and the APR after the promotion. The figures here are Julia's worked examples. No card record sits behind this lesson, so it carries no verification date; confirm current terms with the issuer.
