Once you decide to get out of debt, the next question is which balance to pay first. The two most popular answers are the debt avalanche and the debt snowball. Both work. They just optimize for different things: one saves the most money, the other builds the most motivation. This guide explains both, runs the numbers on an example, and helps you choose.

The ground rules for both methods
Every payoff plan starts the same way:
- List every debt with its balance, interest rate and minimum payment.
- Pay the minimum on every debt, every month, on time. Late payments add fees and can hurt your credit score.
- Decide on one extra amount you can pay each month, on top of the minimums.
- Send that extra amount to one “target” debt until it is gone.
- When a debt is paid off, roll its minimum payment plus the extra amount into the next target.
The only difference between avalanche and snowball is which debt is the target.
The debt avalanche: highest interest rate first
With the avalanche, you target the debt with the highest APR first, regardless of balance.
Pros
- Mathematically saves the most interest.
- Usually gets you debt-free slightly sooner.
- Makes sense if you are motivated by numbers and efficiency.
Cons
- If your highest-rate debt is also large, it can take months before you see a balance disappear, which can be discouraging.
The debt snowball: smallest balance first
With the snowball, popularized by Dave Ramsey (see our post on financial freedom with Dave Ramsey), you target the smallest balance first, regardless of rate.
Pros
- Quick wins: small balances vanish fast, which builds momentum.
- Fewer accounts to track sooner.
- Research on consumer behavior suggests that early wins can help people stay with a plan.
Cons
- You may pay more total interest than with the avalanche.
A worked example
Imagine you have $500 a month to put toward these debts:
- Store card: $900 balance, 27% APR, $35 minimum
- Credit card A: $4,500 balance, 24% APR, $120 minimum
- Personal loan: $6,000 balance, 11% APR, $190 minimum
Total minimums are $345, so you have $155 a month extra.
Avalanche order: store card (27%), credit card A (24%), personal loan (11%). Here the highest rate also happens to be the smallest balance, so both methods start in the same place. That happens often with store cards.
Snowball order: store card ($900), credit card A ($4,500), personal loan ($6,000). Same order in this example.
Now change one detail: say credit card A charges 29% instead of 24%. The avalanche would attack credit card A first, while the snowball would still clear the $900 store card first. Over the life of the plan, the avalanche would save some interest — often a modest amount, sometimes a few hundred dollars, depending on balances — while the snowball would give you a paid-off account within about five months.
Run your own numbers with the Free Debt Tracker or any free online payoff calculator; the difference is often smaller than people expect.
How to choose
Ask yourself one question: “What has made me quit plans in the past?”
- If you quit because progress felt invisible, choose the snowball.
- If you quit because you felt like you were wasting money, choose the avalanche.
- If you are not sure, try a hybrid: knock out any balance under about $1,000 first for a quick win, then switch to avalanche order.
The best method is the one you follow for the full 18, 24 or 36 months it takes.
Ways to speed up either method
- Lower the rate. Call your card issuer and ask for a lower APR, or consider a balance transfer card with a 0% intro period. Watch out for transfer fees (often 3–5%) and the rate after the promo ends.
- Consolidate carefully. A fixed-rate personal loan can replace several card payments with one lower-rate payment — but only if you stop adding new card balances.
- Find extra cash. Selling unused items, side income, or — if it fits your situation — selling some investments. Our guide Should You Use Crypto to Pay Off Debt? walks through that decision.
- Automate. Set the minimums and the extra payment to auto-pay right after payday.
- Track spending. See our guide to tracking expenses.
What about debt relief companies?
Debt settlement programs negotiate with creditors to accept less than you owe, but they can damage your credit, charge significant fees and create tax consequences on forgiven debt. Nonprofit credit counseling and a debt management plan are often a safer first step. We covered the landscape in Finding Relief: Navigating Debt and 5 Tips for Managing Debt.
Common mistakes to avoid
- Closing paid-off cards immediately (it can raise your credit utilization ratio; consider keeping no-fee cards open and unused).
- Skipping the emergency fund, which pushes surprise expenses back onto cards.
- Investing aggressively — especially in volatile assets like crypto — while carrying high-interest debt.
- Not celebrating milestones. Small, cheap rewards help you keep going.
Bottom line
Avalanche saves the most money; snowball builds the most momentum. Both beat making minimum payments forever. Pick one today, write the order down, and automate the first extra payment.

Frequently asked questions
Does the avalanche always save more money than the snowball?
In total interest, the avalanche will never cost more than the snowball, because it always targets the most expensive balance. But the gap depends on your numbers. When your highest-rate debt is also small, the two methods are identical. When rates are close together, the savings can be small. When you have a large, very high-rate balance and several small, low-rate balances, the avalanche can save noticeably more.
What if two debts have almost the same rate?
Pay the smaller balance first. You give up almost nothing in interest and you get a paid-off account sooner.
Should I include my mortgage or car loan?
Most people leave the mortgage out of a payoff plan and focus on consumer debt first. Auto loans and student loans can be included once credit cards are gone, especially if their rates are high.
What about 0% promotional balances?
Treat a 0% balance by its promo end date. Divide the balance by the months left in the promo and pay at least that amount, or the go-to rate can turn it into your most expensive debt overnight.
How long will it take?
Add up your balances, then divide by your total monthly payment (minimums plus extra). That gives a rough number of months; interest will add some time. Recalculate every quarter — most people get faster as each payment rolls into the next.
Should I stop investing while I pay off debt?
Keep any employer retirement match. Many people pause other optional investing, including crypto purchases, until high-interest debt is gone, because a 20%+ APR is a guaranteed cost while investment returns are not.
What happens to my credit score?
Paying down revolving balances generally lowers your credit utilization, which is a major scoring factor. On-time payments help too. Closing old accounts can sometimes have the opposite effect, so think before you close them.
