Compare both debt payoff strategies side-by-side to see which saves more money and which gets you debt-free faster.
For $8,000 in total debt with $200 extra monthly, the avalanche method saves $117 more in interest by targeting high-APR debt first. The snowball method pays off smaller debts first for quicker wins but costs more total. Use this calculator with your actual debts to see which works best for you.

The debt avalanche method typically saves more in interest by prioritizing high-rate debts, while the snowball method may provide faster psychological wins.

The debt snowball method focuses on paying off your smallest debt balance first, regardless of interest rate. You make minimum payments on all debts while putting extra money toward the smallest balance.
Once the smallest debt is paid off, you roll that payment into the next smallest debt, creating a "snowball" effect that builds momentum as each debt is eliminated.
The debt avalanche method prioritizes debts with the highest interest rates first. You make minimum payments on all debts while directing extra payments to the debt charging the most interest.
This mathematical approach minimizes total interest paid, so it costs less overall than the snowball method. It rarely moves your finish date much: with the same monthly budget, the two methods usually finish in the same month or one month apart (in this calculator's starting example, both take 22 months).
The debt avalanche almost always saves more money because it targets high-interest debt first, reducing the amount of interest that accrues over time.
However, the debt snowball can provide psychological benefits through quick wins. Some people find these early victories motivating enough to stick with their debt payoff plan, which may be more valuable than saving a few hundred dollars in interest.
Any extra payment beyond minimums shortens your payoff and cuts the interest you pay. On this calculator's starting example ($8,000 on two cards, $240 a month in minimums, each paid-off card's minimum rolled to the next), an extra $50 a month saves $760 in interest with the snowball or $882 with the avalanche and finishes 11 months sooner; an extra $100 a month saves $1,246 or $1,380 and finishes 18 months sooner.
The gap between the two methods does not simply shrink as you pay more. On the same example, the avalanche saves $122 more interest than the snowball with an extra $50 a month, $134 more with $100 and $117 more with $200; only at larger extra payments does the gap narrow, to $71 at $500 and $41 at $1,000.
This calculator runs two independent payoff simulations over the same list of debts and extra payment amount. The avalanche method sorts your debts by interest rate, highest first, and directs every dollar of extra payment to the highest-rate debt while paying the minimum on the rest; once that debt is gone, its payment rolls into the next-highest-rate debt. The snowball method uses the same simulation but sorts by balance, smallest first, so the extra payment attacks your smallest debt regardless of its rate.
Comparing the two totals — months to debt-free and total interest paid — shows the guaranteed-lowest-interest option (avalanche) against the get-a-quick-win option (snowball).
The debt snowball method pays off debts from smallest to largest balance regardless of interest rate, while the debt avalanche method prioritizes debts with the highest interest rates first. Both methods require paying minimums on all debts while applying extra payments strategically.
The debt avalanche saves more money in interest by targeting high-rate debts first. However, the debt snowball can provide psychological wins through quick payoffs of smaller debts, which helps some people stay motivated. The best method depends on your personal situation and what keeps you motivated.
The debt snowball typically costs more in total interest than the debt avalanche because it doesn't prioritize high-interest debts. However, it can save you money compared to making only minimum payments, and the psychological benefits may help you stick with your debt payoff plan.
Making extra payments beyond minimums can reduce your debt payoff time by months or years. The exact timeline depends on your total debt, interest rates, and how much extra you can pay each month. Both snowball and avalanche methods accelerate payoff compared to minimum payments only.

Paying extra toward your debts in a planned order can save you a significant amount of interest and make you debt-free months or years sooner than paying minimums alone. The two most popular methods are the debt snowball and debt avalanche, each with distinct advantages depending on your financial situation and psychological needs.
The debt snowball method, popularized by financial expert Dave Ramsey, focuses on paying off your smallest debt balance first, regardless of interest rate. Here is how it works:
The snowball method provides quick wins that build momentum. Paying off a small $500 credit card in 2-3 months feels rewarding and motivates you to keep going. Research from the Harvard Business Review shows that people who focus on small wins are more likely to persist with their debt payoff goals.
Best for: People with multiple small debts, those who need motivation to stay on track, individuals who have struggled with debt payoff plans in the past, or anyone who values psychological wins over pure math optimization.
The debt avalanche method prioritizes mathematical efficiency by targeting the highest interest rate debts first. Here is the process:
The avalanche method minimizes total interest paid over the life of your debt. By eliminating high-interest debt first (often credit cards at 20-25% APR), you stop the most expensive interest from compounding. How much more it saves than the snowball depends on your debts. On this calculator's starting example ($8,000 on two cards at 19.99% and 15.99%), the avalanche saves $41 to $134 more in interest, with $50 to $1,000 a month extra. The gap grows with larger balances and a wider spread between your rates; when your rates are close, the two methods cost almost the same.
Best for: Mathematically-minded individuals, those with significant high-interest debt, people with strong self-discipline, or anyone focused on minimizing total cost regardless of how long it takes to see progress.
| Factor | Debt Snowball | Debt Avalanche |
|---|---|---|
| Order of payoff | Smallest balance first | Highest interest first |
| Best for | Quick wins, motivation | Maximum interest savings |
| Total interest paid | Higher | Lower (optimal) |
| Time to first payoff | Usually faster | May take longer |
| Psychology | Easier to stick with | Requires more discipline |
| Recommended by | Dave Ramsey | Most financial mathematicians |
The best debt payoff strategy depends on your unique situation. Consider these factors:
Hybrid approach: Some people start with the snowball method to build momentum by paying off one or two small debts, then switch to the avalanche method for maximum efficiency. This combines psychological benefits with mathematical optimization.
The best debt payoff method is the one you will actually stick with. The avalanche saves more money mathematically, but if the snowball keeps you motivated to continue, it is the better choice for you. Use this calculator to compare both methods with your actual debts, then choose the strategy that fits your personality and financial goals.
