Is the snowball method or avalanche method better?

The avalanche method (highest APR first) saves more money in interest. The snowball method (lowest balance first) pays off individual debts faster, providing psychological wins that help people stay on track. Research suggests that the snowball method may lead to better real-world results because motivation is a major factor in debt repayment success.

How do I use this debt snowball calculator?

Enter your monthly payoff budget, then add each debt with its current balance, APR, and minimum payment. The strategy is pre-set to Snowball. Click Calculate to see your payoff date, total interest, and a month-by-month payment schedule you can download as a CSV.

Can I include credit cards, student loans, and car loans?

Yes. Add any debt with a balance, APR, and minimum payment — credit cards, auto loans, personal loans, student loans, or medical bills. The calculator handles mixed debt types in the same plan.

Is my debt information stored anywhere?

No. All calculations happen entirely in your browser. Your balances, APRs, and payment details are never sent to any server. Closing the tab clears everything.

How the snowball works here

All debts receive their minimum payment each month.
Any budget left over goes entirely to the smallest balance.
Once that debt hits zero, its freed-up payment joins the next smallest.
Switch to Avalanche in the strategy dropdown to compare interest savings.

What Is the Debt Snowball Method?

The core idea

The debt snowball method, popularized by personal finance expert Dave Ramsey, focuses on paying off the smallest debt balance first, regardless of interest rate. You list your debts from smallest to largest balance, pay minimums on everything, and throw every extra dollar at the smallest debt.

When that debt is gone, you take its minimum payment and add it to the next smallest — that growing payment is the "snowball" rolling downhill, picking up speed.

Step-by-step

List all debts from smallest to largest balance.
Pay the minimum on every debt except the smallest.
Put every extra dollar toward the smallest balance.
When it's paid off, roll that payment to the next smallest.
Repeat until debt-free.

Why it works psychologically

You eliminate entire debts faster than any other strategy. Seeing a balance hit zero — even a small one — releases real motivation. Studies on consumer debt repayment suggest that quick wins increase the probability of sticking with a repayment plan long enough to finish it.

Fewer accounts to manage over time.
Visible, measurable progress early in the plan.
Freed minimum payments increase momentum month over month.

Snowball vs Avalanche — when to choose each

Choose Snowball if you've tried (and abandoned) debt repayment before. Motivation matters more than math when you're starting out.
Choose Snowball if your smallest debt balances are close in size to your higher-rate debts — the cost difference may be minimal.
Choose Avalanche if you have a high-rate card that dwarfs other balances — the interest savings can be substantial.
Use this calculator to compare: switch the strategy dropdown between Snowball and Avalanche and compare the Interest Saved figures.

Tips for Using the Snowball Calculator

Find your real budget

Start with the sum of your current minimum payments as the baseline budget.
Add any extra amount you can commit each month — even $50 makes a difference.
Run the calculator with different budgets to see the payoff date shift.

Model windfalls

Got a bonus or tax refund? Reduce the first debt's balance to reflect a lump-sum payment, then recalculate.
If a 0% promo card is in your plan, set its APR to 0 now and re-run when the promo ends.
Use the CSV export to share your plan or track actual vs projected progress.

FAQ

What is the debt snowball method?

The debt snowball method means paying minimum payments on all debts and directing every extra dollar to the smallest balance first. When it's paid off, that freed payment rolls to the next smallest — the growing payment "snowballs" over time.

Does the snowball method cost more than avalanche in interest?

Often yes — sometimes by a few hundred dollars, sometimes more. But the gap depends heavily on your specific balances and rates. Use the strategy dropdown to switch between Snowball and Avalanche in this calculator and compare the Interest Saved numbers for your exact debts.

Can I model a 0% APR credit card in this calculator?

Yes. Enter that card's balance with APR set to 0. When the promotional period ends, update the APR and recalculate.

What if I can't afford more than the minimum payments?

Set your budget to the sum of all minimum payments. The calculator will still show your payoff timeline — just without extra payoff acceleration. Even small additions above minimums make a meaningful difference over time.

How do I prioritize a specific debt?

Switch to the Custom strategy in the dropdown, then use the up/down buttons to order debts manually. This lets you override the snowball order for any reason — like wanting to pay off a specific card early.
