Best free debt payoff planner: Undebt.it. Best for automated extra payments: Changed. Best if you need budgeting and debt payoff in one place: YNAB.

Credit card APRs have dropped for six consecutive months. The average rate on new offers is down to 22.35% — the lowest since March 2023. That’s the good news. The bad news: American credit card balances still sit at $1.23 trillion as of Q3 2025, and they haven’t come down meaningfully despite the rate relief.

Here’s the tension. Rates are falling, but not fast enough to matter on a $6,000 balance. At 22.35%, you’re still paying $112 per month in interest alone just to tread water. The Fed held at 3.50–3.75% on March 18 with another decision coming April 29 — more cuts are possible, but “possible” doesn’t help your minimum payment right now.

I’ve carried credit card debt twice. Once in my mid-twenties (poor decisions) and once two years ago (emergency vet bill plus a transmission failure in the same month). Both times, the app I used to plan payoff made the difference between sticking with it and losing track. Not because the apps did anything magical. Because seeing a projected payoff date — and watching it move closer every time I made an extra payment — turned an abstract weight into a concrete project.

With consumer sentiment at 53.3 on the Michigan survey and Goldman Sachs estimating that 55–70% of tariff costs will hit households directly in 2026 (up from 20% last year), a lot of people are staring at credit card statements and feeling the squeeze. If that’s you, here’s what’s worth using.

How Debt Payoff Apps Actually Help

A debt payoff app doesn’t pay your debt. You do. What the app does (if it’s built right) is remove the mental overhead of figuring out where to send extra money and how long this is going to take.

The psychological piece matters more than most people admit. A 2024 study from the National Bureau of Economic Research found that people who could see a projected payoff date were 22% more likely to make extra payments than those who just saw a balance. Not because they had more money. Because they had a target.

What’s the Difference Between Avalanche and Snowball?

Two methods dominate the debt payoff world. Which one an app supports (or defaults to) matters.

1. Debt avalanche: Pay minimums on everything, throw extra money at the highest-interest debt first. Mathematically optimal. Saves the most in interest over time.
2. Debt snowball: Pay minimums on everything, throw extra money at the smallest balance first. Mathematically suboptimal. Psychologically effective because you eliminate individual debts faster, which builds momentum.
3. The real answer: The method you’ll stick with for 18 months beats the method you abandon after 6 weeks. If seeing a card go to $0 in three months keeps you going, snowball wins even though avalanche saves you $300 in interest. I started with snowball, switched to avalanche after knocking out two small balances. That’s allowed.

The Apps, Ranked

Undebt.it — Best Free Debt Payoff Planner

Undebt.it is a web-based debt payoff planner that does one thing exceptionally well: it shows you exactly when you’ll be debt-free under different strategies, and what each strategy costs in total interest.

You enter your debts (balance, APR, minimum payment), pick a method (avalanche, snowball, or eight other approaches including highest-balance-first and debt-to-income ratio), set your total monthly payment amount, and Undebt.it generates a month-by-month payoff schedule. The table shows every payment, split between principal and interest, for every debt, for every month until you’re done.

I ran my numbers through it when I was carrying $8,200 across two cards. Avalanche saved me $340 in interest over snowball on a 14-month payoff. Seeing that number made the decision easy. But Undebt.it also showed me that if I added just $75/month to my total payment, the payoff date moved forward by four months. That was the number that actually changed my behavior.

The free tier is enough for most people. Premium ($12/year — not per month) adds automatic balance syncing through a spreadsheet integration and a few extra visualizations. Twelve dollars a year is nearly free by personal finance app standards.

Good for: Anyone who wants a clear plan. People deciding between avalanche and snowball who want to see the actual dollar difference. Spreadsheet-minded people who want more structure than a DIY tracker.

Skip if: You need automated payments or bank linking. Undebt.it is a planner, not a payment tool. You still make payments yourself through your bank or card issuer.

Changed — Best for Automated Extra Payments

Changed connects to your bank account, rounds up your purchases to the nearest dollar (or $2, or $5 — you pick), and sends those round-ups directly to your credit card as extra payments. Think Acorns, but for debt instead of investing.

The concept is simple enough to feel trivial. It’s not. Over the three months I used Changed, my round-ups averaged $67/month in extra payments that I genuinely didn’t miss from my checking account. On an $4,800 balance at 22% APR, an extra $67/month cuts nearly five months off a standard minimum-payment timeline.

Changed also lets you set “power-ups” — one-time or recurring boosts on top of round-ups. I set a $25/week power-up on Fridays and combined with round-ups, I was sending an extra $170/month to my highest-rate card without actively thinking about it. That’s the whole point. Debt payoff grinds to a halt when it requires willpower every single time.

$3/month for the basic plan, $5/month for premium (which adds the ability to pay multiple debts and choose avalanche or snowball priority). The $5 tier is worth it if you’re juggling more than one balance.

Good for: People who know they should make extra payments but don’t. If your problem is execution rather than strategy, Changed solves it. Also good for people who respond better to automated systems than manual discipline.

Skip if: Your checking account balance is tight enough that random round-ups could cause overdrafts. Changed has a low-balance protection feature, but I’d still be cautious if you’re running close to the edge.

Debt Payoff Planner — Best Simple Mobile Tracker

Debt Payoff Planner is the app equivalent of writing your debt payoff plan on a notecard and checking it every week. It’s basic. It works.

Enter your debts, pick snowball or avalanche, set your extra monthly payment amount. The app generates a payoff timeline with a month-by-month schedule. As you make payments, you log them in the app and watch the projected payoff date adjust.

No bank linking. No automated payments. No AI. You open the app, see where you are, see where you’re going, and close it. That simplicity is the selling point for people who are overwhelmed by financial apps that try to do everything.

The free version handles up to four debts. The Pro upgrade ($4.99 one-time, no subscription) unlocks unlimited debts and removes ads. One-time purchase pricing feels almost nostalgic in 2026.

Good for: People who want a simple tracker on their phone. Anyone who’s tried bigger financial apps and abandoned them because they were too much.

Skip if: You need automation, bank syncing, or anything beyond a calculator with memory. This is deliberately minimal.

YNAB — Best Budgeting + Debt Payoff Combo

I’ve written about YNAB at length. It’s not a debt payoff app specifically. It’s a budgeting app that happens to be exceptionally good at debt payoff because of how it forces you to assign every dollar.

For debt, you create a category for each credit card. Your minimum payments get budgeted like any other bill. When you have extra money — from cutting a subscription, getting a side gig payment, spending less on groceries — you move that money to your target card’s category and make the payment. YNAB’s “debt paydown” goal tracks your progress and projects when you’ll hit zero.

What makes YNAB different from a pure debt calculator is that it attacks both sides of the equation. The payoff planner tells you where to send extra money. YNAB helps you find extra money by making every spending decision visible. When you’re carrying $8K in credit card debt at 22.35% and tariffs are adding costs to your household, finding an extra $50 inside your existing budget matters as much as choosing avalanche over snowball.

$14.99/month. Expensive. But if you need help with both the “how to budget tighter” and “how to pay off debt faster” problems simultaneously, one subscription covers both. I covered cheaper budgeting alternatives in the recession-proofing guide if you’re looking for the budgeting side without the cost.

Good for: People whose debt problem is partly a spending problem. Anyone who’s made payoff plans before and couldn’t stick to them because unexpected expenses kept derailing the math.

Skip if: Your budget is already tight and well-managed, and you just need a tool to optimize payment order. Use Undebt.it for free and send the $15/month to your highest-rate card instead.

Qoins — Budget-Friendly Round-Ups

Qoins works like Changed — round up transactions and send the difference to debt, but at a lower price point ($2.99/month) with fewer features. You pick one debt to target, connect your bank, and Qoins accumulates round-ups until they hit a threshold, then sends a lump payment.

The key difference from Changed: Qoins batches payments rather than sending them continuously, and the free tier limits you to a single debt account. If you’re focused on one card (which you should be, whether avalanche or snowball), the single-debt limit isn’t a problem.

My round-ups through Qoins averaged $45–55/month. Less than Changed, partly because Qoins doesn’t have the “power-up” boosts and partly because the rounding options are more limited.

Good for: People who want the round-up approach at a lower cost and are focused on one debt at a time. The $2.99/month price makes the ROI math easier to stomach.

Skip if: You need to target multiple debts simultaneously or want more control over extra payment amounts. Changed’s $5 premium tier is better for that.

Unbury.me — Best Quick Calculator

Unbury.me is a free, no-signup debt payoff calculator. Open the website, enter your debts, toggle between avalanche and snowball, see the difference. That’s it. No account. No app. No data collection. Just math.

I use Unbury.me for quick what-if scenarios. “What if I throw my tax refund at the high-rate card? How much does that change the timeline?” I can answer that in 30 seconds without logging into anything or updating a balance.

It’s not a replacement for an actual tracking app. But it’s the fastest way to see whether avalanche or snowball makes a meaningful difference for your specific debts, and it’s the first thing I’d point someone to who’s just starting to think about a payoff strategy.

Good for: Quick comparisons. First step before committing to a full payoff app. People who don’t want to create yet another account.

The App That No Longer Exists: A Cautionary Note

Tally was the best debt management app I’d ever used. It analyzed your credit cards, figured out the optimal payment strategy, and made your payments automatically — on time, allocated correctly, with a line of credit that covered your minimums if cash was tight. Then it shut down in late 2023 after running out of funding.

I bring this up because fintech apps, especially ones that extend credit, carry counterparty risk. If your debt payoff strategy depends entirely on an app that handles your payments, you need a backup plan for the day that app sends you a “we’re sunsetting” email. Prefer apps where you control the payment (Undebt.it, Debt Payoff Planner) or where the app merely initiates round-ups from your existing bank account (Changed, Qoins). Don’t let a single app become a single point of failure for your payoff plan.

Why the APR Drop Matters (and Why It’s Not Enough)

Credit card APRs at 22.35% are better than the 23.4% peak six months ago. On a $6,000 balance, that one percentage point drop saves you roughly $60 in interest over a year. Real money, but not life-changing.

The bigger opportunity is what’s coming. The Fed held rates at 3.50–3.75% on March 18, but markets are pricing in additional cuts through the rest of 2026. If rates drop another 50 basis points, credit card APRs will likely follow with a lag — potentially getting below 21% by year-end.

Here’s the move: start your payoff plan now at 22.35% and let the rate drops accelerate your timeline. If you’re using avalanche method and sending $300/month toward a $6,000 balance, every quarter-point APR drop shaves roughly two weeks off your payoff date. Not because you’re doing anything differently. Because more of each payment hits principal when the rate decreases.

Don’t wait for rates to drop further before starting. The interest you pay between now and “later” exceeds whatever you save from a lower rate.

How to Pick the Right App for Your Situation

Carrying debt on one card under $5,000: Unbury.me to pick your method, then Debt Payoff Planner to track it. Total cost: $0–$4.99 one-time.

Multiple cards, over $5,000 total: Undebt.it to build your strategy, Changed ($5/month) to automate extra payments. You get the plan and the execution.

Debt problem that’s also a spending problem: YNAB. It costs more, but it attacks the root cause — uncontrolled spending — alongside the symptom. If your credit card balance keeps growing because expenses exceed income, a payoff app alone won’t fix it. You need budgeting discipline first.

Tight budget, can’t afford another subscription: Undebt.it (free) or Unbury.me (free) for planning. Manual extra payments through your bank’s bill pay. Set a calendar reminder. Not glamorous. Works.

Already budgeting with YNAB or Monarch: You don’t need a separate debt payoff app. Both have debt tracking built in. Just set up debt paydown goals and use the payoff calculators to decide payment order.

What Happens If the Recession Actually Hits

Consumer sentiment at 53.3 isn’t great. Goldman’s estimate that households absorb 55–70% of tariff costs in 2026 means budgets are tightening even without a formal recession. If it actually arrives, the calculation shifts.

During a recession, the priority isn’t paying off debt fastest — it’s maintaining cash reserves while still making progress. That might mean switching from aggressive extra payments to minimum payments plus a small buffer, redirecting what you can to an emergency fund. A $1,000 cash cushion matters more than paying off your Visa two months early if your employer starts talking about layoffs.

The debt payoff apps above all let you adjust your extra payment amount. Dial it down if income gets uncertain. Dial it back up when things stabilize. The worst move is abandoning the plan entirely because it feels pointless — even minimum payments with a plan beat minimum payments without one, because you’re tracking progress instead of ignoring the balance.

The Bottom Line

APRs are falling. That’s real. But 22.35% is still brutal on a large balance, and waiting for rates to drop further costs you more in interest than you’ll save. Pick an app — free is fine, Undebt.it or Unbury.me will get you started in ten minutes — build your payoff plan, and let every future rate cut accelerate a strategy that’s already in motion.

The math is less important than the momentum. Avalanche saves more in interest. Snowball builds faster wins. But the plan you actually follow for 12 months beats the optimal plan you quit after 8 weeks. Start there.
