Debt Payoff Planner Apps Compared: The Best Debt Payoff App for Credit Card Debt

The best debt payoff planner for most people with credit card debt is Undebt.it, because the free tier already does the job and the paid tier costs $10 a year. Debt Payoff Planner is the better phone-first option, with a free version and a Pro tier from $2 a month. YNAB at $14.99 a month and Monarch are budgeting tools that can hold a payoff plan rather than payoff planners, and Tally, which several roundups still list, shut down in August 2024.

All of these were checked against each company's own pages in August 2026. Prices move, so re-read them before you subscribe to anything.

There is one thing none of them do, and it is the reason this comparison exists on a credit site rather than a budgeting one. Every app here plans the payoff in dollars and months. None of them tells you the month your credit utilization drops below 30 percent, which is the part a lender actually sees while you are still paying the debt down.

Debt payoff apps compared

Read the table with one question in mind: are you buying a plan, or are you buying a budget? Undebt.it and Debt Payoff Planner sell you a schedule for debt you already have. YNAB and Monarch sell you a system for all your money, and the payoff is one line inside it. Both are legitimate purchases. They are not substitutes, and paying $109 a year for a budgeting app because you wanted a payoff schedule is the most common way people overpay here.

What is the best app to pay off debt?

For credit card debt specifically, Undebt.it. The free tier lets you enter your debts, pick snowball or avalanche, add extra payments, and see the resulting schedule, which is the whole job for most people. Undebt.it+ at $10 a year unlocks unlimited accounts, all eight payoff methods, Excel export, payment reminders and historical reporting. Ten dollars a year is close to a rounding error against the interest at stake.

Undebt.it is also the only tool in this comparison that even acknowledges credit utilization exists: one of its eight payoff orderings is highest credit utilization first, which sequences your debts by how close each card is to its limit rather than by balance or rate. That is a genuinely useful ordering if you have a mortgage or auto application coming up, because a single card reporting near its limit is visible to lenders on its own.

If you want the plan on your phone rather than in a browser, Debt Payoff Planner is the straightforward pick. Free to start, Pro from $2 a month, snowball and avalanche side by side, and a countdown to the debt free date. It does less than Undebt.it and it does it with fewer taps.

Do debt payoff apps actually work?

They work as calculators and as trackers, and that is worth being precise about, because none of them move money or negotiate anything. What they do is turn an abstract pile of debt into a dated schedule, and then show you what one more dollar a month does to that date. The behavioral value of watching a payoff date move toward you is real, and it is most of what people are actually paying for.

What they do not do is find the money. The extra payment has to come from somewhere, and for most people that means spending they have not looked at closely in a year or more, which is the gap that software that reads your receipts and categorizes every expense is built to close. An app that tells you a $300 payment clears your card in 21 months is not helpful until you know whether $300 exists.

The other honest limit is accuracy. These tools assume a fixed APR, a fixed payment and no new charges. Real cards carry separate rates for purchases, cash advances and balance transfers, and issuers apply anything above the minimum to the highest rate balance first. The schedule is a good estimate, not a contract.

Snowball or avalanche: which one should the app use?

Avalanche, highest interest rate first, is provably cheaper in total interest, because the fastest compounding balance gets killed first. If your only goal is to spend the least money, there is no serious argument for anything else, and every tool here supports it.

Snowball, smallest balance first, costs more and wins on follow through. Clearing an entire account in the first two months produces a visible result at a point in the process where most people quit. If you have abandoned a payoff plan before, the method with the worse arithmetic is often the one that finishes. We work through both orderings, with the numbers, in how to pay off credit card debt and raise your score.

There is a third ordering worth knowing about that only Undebt.it offers by default: highest credit utilization first. It is the worst of the three on total interest and the best of the three if a lender is going to pull your file in the next few months, because it attacks the card that looks worst on a credit report rather than the one that costs the most.

What happened to Tally?

Tally shut down in August 2024. The company had raised $172 million, was backed by a16z, and had pivoted to a business to business model four months earlier before running out of cash and laying off more than 180 people. Its consumer product was different from everything else here: it extended you a line of credit at a rate between roughly 8 and 30 percent and used it to pay your cards, so you owed Tally instead of your issuers.

It is worth naming because a surprising number of best debt payoff app roundups published in 2025 and 2026 still list Tally as a live option. If a comparison page recommends it to you, that page has not been checked since 2024, and you should discount everything else on it accordingly.

Do any debt payoff apps show the effect on your credit score?

No, and this is the gap. Every tool in the table models dollars and months. Utilization is your reported balance divided by your reported limit, it is roughly 30 percent of a FICO score, and it improves gradually as the balance falls rather than on the day the account finally reads zero. A payoff plan that ignores it is only telling you half of what the plan is doing for you.

That is what our credit card payoff calculator adds. Enter the balance, the APR, the payment and the credit limit, and it returns the usual months and total interest plus the month the balance crosses 30 percent and 10 percent of that limit. It also prices your fixed payment against paying only the minimum, and it flags the case people fall into most often: a flat payment set below your current minimum can cost more total interest than minimums would, because minimums start high and shrink while a flat payment does not.

If you are running several cards at once, the multi-card credit utilization calculator gives you the aggregate ratio that scoring models read alongside the per-card one, and flags which card is dragging the file down. That is usually the number that decides which debt to attack first when a mortgage is on the horizon.

Is Undebt.it free?

Yes, there is a genuinely free tier and it does not ask for a card to try the calculator. Undebt.it+ is the paid membership at $10 a year, billed as a single annual payment rather than a recurring monthly subscription, with a 30 day trial. The company has said the $10 figure is introductory and will rise as features are added, so treat it as current rather than permanent.

The free tier covers snowball and avalanche, a payment schedule, and progress tracking. What you buy with the $10 is unlimited debt accounts, the other six payoff methods, Excel export, bill tracking for non debt expenses, text payment reminders, historical reporting and no ads. If you have more than a handful of accounts, the account limit is usually the thing that pushes you over.

Which one should you pick?

If you have credit card debt and want a schedule: Undebt.it, free tier first, $10 a year if you hit a limit. If you want it on your phone: Debt Payoff Planner. If your real problem is that you do not know where your money goes and the debt is a symptom: YNAB, and expect to spend a few weeks learning it before it pays for itself. If a roundup recommends Tally: close the tab.

Then, whichever you pick, run the schedule through a calculator that knows what utilization is. The payoff date is the number the app gives you. The month your file stops looking maxed out is the number a lender responds to, and it usually arrives a long time before the balance hits zero. If a higher limit is available to you, the credit limit increase calculator prices that lever against the paydown so you can see which one gets you there cheaper.

Creditpal is educational. We do not lend, we do not file disputes, we do not move money, and nothing here is financial advice or a promise of a specific score change.
