If you're carrying a few credit cards and a loan or two, you probably know the balances by heart. What's harder to know is the answer to the question that actually matters: when does this end? Most people guess, and the uncertainty makes the whole thing feel heavier than it needs to.
Debt Payoff is a small, focused app that takes your balances, interest rates, and monthly budget, and turns them into a concrete calendar. You can see which debt clears first, which method saves you the most interest, and the exact month your total balance hits zero. Try the live app below, then read on for how it works.

The two strategies, finally side by side
The snowball vs avalanche debate has filled more Reddit threads and personal finance blogs than almost any other money topic, and for good reason: the choice is genuinely personal, and the difference in outcomes can be significant. Snowball has you pay off the smallest balance first, which gives you quick wins and keeps motivation high. Avalanche targets the highest interest rate first, which minimizes what you pay overall.
The frustrating thing is that most articles explain both methods but leave you to do the math yourself, or send you to a spreadsheet that takes twenty minutes to set up. This app does the calculation for both at the same time, with your actual numbers, so you can see the real trade-off. How many months does snowball cost you compared to avalanche? How much extra interest does the emotional win of snowball actually add up to? Those two numbers together let you make a real decision.

Enter your debts, get a dated plan
Setup is quick. Add each debt with three fields: the current balance, the APR, and the minimum monthly payment. You're not linking a bank account, not giving away login credentials, not syncing anything. The numbers stay on your device.
Once your debts are in, enter the total amount you can put toward debt each month. The app allocates minimums to every debt and routes the extra to whichever balance the chosen strategy targets next. The result isn't a vague 'you'll be done someday' message. It's a list: Visa ends in March 2027, the car loan closes in August 2028, and so on, debt by debt, with a final debt-free date at the bottom.
The app ships with seeded example data, so the first screen you see isn't blank. That matters more than it sounds: seeing a populated plan immediately makes the whole thing feel real and tractable, even before you've entered your own numbers.

Watching the balance shrink
The chart showing your total balance dropping to zero over time is the part worth staring at for a moment. It's easy to feel like debt is static, like the numbers just sit there. The chart makes the progress visible, month by month. The line goes down. It reaches zero on a specific date. That date is yours.
Below the chart, you'll see the total interest each method costs, which is where the avalanche case becomes concrete. If avalanche saves you $1,400 in interest, that's $1,400 that stays in your pocket. If snowball gets you to debt-free four months sooner emotionally but costs $900 more, you can weigh that trade-off as a real person making a real decision, not as a math problem.
Built for focus, not for everything
A lot of debt apps want to be your full financial picture: budgeting, savings, investments, net worth, all of it. Debt Payoff does one thing. It answers the question 'how do I get out of debt, and when?' for people carrying two to six consumer debts. Credit cards, store cards, a car payment, a student loan. The kind of debt mix that's genuinely common and genuinely stressful.
There's no subscription, no account creation, and no connection to your bank. It works offline from the moment you open it. For a lot of people, that's exactly the right scope: a private, reliable tool that helps you think clearly about a specific problem, without turning into another app you have to manage.
How to get the most from the demo
The live app embedded above is the real thing. Start by tapping into the existing debts and changing one of the APRs or balances to match something you actually owe. Watch how the payoff dates and total interest numbers update. Then switch between snowball and avalanche and see the difference in your specific situation.
The most useful moment tends to be when you adjust the monthly budget slider upward, even modestly, and see how many months drop off your debt-free date. An extra $50 or $100 a month often moves that date by more than people expect, and seeing it move in real time makes it feel possible to find that extra amount somewhere.
