How this debt payoff calculator works

Enter each debt with its current balance, annual interest rate (APR), and minimum monthly payment. Then add any extra money you can throw at your debt each month. The calculator runs two simulations side by side so you can compare the cost of each strategy before you commit.

The Snowball method

Snowball orders your debts from smallest balance to largest. All extra money goes toward the smallest debt first. When it is paid off, that entire payment rolls into the next smallest. You get quick wins early, which keeps you motivated. Research from the Harvard Business Review found that people who focus on small wins first are more likely to follow through on their debt payoff plan.

The Avalanche method

Avalanche orders your debts from highest interest rate to lowest. All extra money goes toward the most expensive debt first. This method minimizes total interest paid, which means you pay less over the life of your debts. The tradeoff is that your first win might take longer to arrive.

Which one should you choose?

Avalanche saves more money. Snowball builds more momentum. The honest answer is that the method you stick with is the one that works. If seeing a debt disappear in month two keeps you going, Snowball might be worth the extra interest. If you are disciplined and motivated by math, Avalanche will save you the most.

There is a third option. Unburden's Momentum strategy is mathematically constrained to match or beat Avalanche on total interest while giving you the quick wins of Snowball. It dynamically adapts to your specific debt profile. Only available in the app.

Why a calculator is not enough

A calculator gives you a snapshot. It tells you what would happen if everything stays exactly the same: same balances, same rates, same payments, every month until the end. That is useful for the first ten seconds.

Real debt does not work that way. You make an extra payment one month. You miss one the next. Your rate goes up. You consolidate two cards. A calculator cannot keep up with that. You need something that updates as your life changes and keeps you on track when you fall behind.

Unburden is the app this calculator wishes it could be. Update your balances as you pay them down. Watch your Burden Score drop in real time. Get reminders before due dates. Run what-if scenarios to see what happens if you throw an extra $200 at your debt next month. It is free to start and your financial data never leaves your device.

What is the Burden Score?

Your credit score measures your value to lenders. The Burden Score measures your risk to yourself. It is a 0-100 score built on five proprietary stress signals that capture how much pressure your debt is actually putting on your life. A 780 credit score and a Critical Burden Score can exist on the same person.

This calculator can tell you when you will be debt-free. The Burden Score tells you how vulnerable you are right now. You can find yours free in the Unburden app in about 60 seconds.

Common questions

What is the debt snowball method?
The debt snowball method orders your debts from smallest balance to largest. You make minimum payments on every debt except the smallest one, which receives all your extra money. When that smallest debt is paid off, you roll its entire payment into the next smallest balance. This creates a compounding effect where each payoff frees up more money for the next debt. The method was popularized by Dave Ramsey and is backed by research from the Harvard Business Review showing that people who focus on small wins first are more likely to follow through on long-term financial goals. The tradeoff is that you may pay more in total interest compared to the avalanche method, because you are not prioritizing high-rate debts first. Unburden's debt payoff calculator shows the exact interest difference so you can decide whether the motivation boost is worth the cost.
What is the debt avalanche method?
The debt avalanche method orders your debts from highest interest rate to lowest. You make minimum payments on every debt except the one with the highest APR, which receives all your extra money. When that debt is paid off, you move to the next highest rate. Because you are always attacking the most expensive debt first, the avalanche method minimizes total interest paid across all your debts. This makes it the mathematically optimal strategy for saving money. The tradeoff is psychological: your first payoff may take longer to arrive, which can make it harder to stay motivated. Unburden's debt payoff calculator runs both avalanche and snowball simulations side by side so you can compare the total interest cost, payoff timeline, and monthly payment flow for each strategy before choosing.
Which is better, snowball or avalanche?
Avalanche saves more money on interest. Snowball gives faster psychological wins. The best method is whichever one you will actually stick with. Research from Northwestern University and the Harvard Business Review shows that people who see early progress are significantly more likely to complete their debt payoff plan, even if the snowball approach costs slightly more in interest. If your debts have similar interest rates, the difference in total cost between the two methods is often small. If you have one debt with a much higher rate than the others, avalanche becomes more compelling. Unburden's debt payoff calculator shows both strategies side by side with exact dollar amounts so you can see the real cost of choosing motivation over math. The Unburden app also offers a third option called Momentum, which is designed to combine the benefits of both.
How accurate is this calculator?
Unburden's debt payoff calculator provides estimates based on the balances, interest rates, and minimum payments you enter. It assumes you make consistent monthly payments at fixed interest rates for the entire payoff period. The calculations use standard amortization math with monthly compounding. Actual results will vary if your interest rates change, you miss payments, incur new charges, or pay variable amounts each month. Credit cards in particular may have promotional rates that expire, which would change your real payoff timeline. For a tool that updates as your situation changes, the Unburden app lets you adjust balances after each payment, re-run strategy comparisons in real time, and track your Burden Score as your debt decreases. The app is free to start with up to three debts, and your financial data never leaves your device.
What is the Burden Score?
The Burden Score is a 0-100 financial vulnerability score available free in the Unburden app. Your credit score measures your value to lenders. Your Burden Score measures your risk to yourself. A 780 credit score and a Critical Burden Score can exist on the same person.

Disclaimer: Unburden is a planning tool, not a financial advisor. The calculations above are estimates based on the information you provide and assume consistent monthly payments at fixed interest rates. Actual results will vary based on individual circumstances, rate changes, and payment behavior. The Burden Score is an educational estimate, not financial advice. If you are struggling with debt, consider speaking with a Licensed Insolvency Trustee.
