Quick answer
The debt avalanche method pays the minimum on every debt and sends all extra money to the debt with the highest APR. When it is gone, that payment moves to the next highest rate. It is the cheapest payoff order, because the most expensive balance shrinks first.
Interest is charged on what you owe at each debt's own rate. So a dollar of extra payment saves the most when it goes to the debt with the highest APR. That is the whole idea behind the debt avalanche.
How the avalanche works
- List each debt with balance, APR and minimum payment.
- Sort by APR, highest first.
- Pay every minimum on time.
- Put all extra money on the highest-APR debt.
- When it is paid off, roll its full payment into the next highest rate.
Worked example
Same three debts as in our snowball guide, $500 a month in total, no new charges. An illustration, not an offer.
| Order | Debt | Balance | APR |
|---|---|---|---|
| 1 | Card B | $6,500 | 26.99% |
| 2 | Card A | $3,200 | 21.99% |
| 3 | Store card | $900 | 17.99% |
| Method | All debts gone | Total interest |
|---|---|---|
| Avalanche | 28 months | about $3,357 |
| Snowball | 29 months | about $3,721 |
The avalanche saves about $364 and finishes a month earlier. The trade-off: the first account is not cleared until month 23. See your own numbers in the debt payoff calculator.
When the avalanche is the clear choice
- One or two debts carry much higher rates than the rest.
- The balances are large, so interest differences add up.
- You are motivated by the total you save, not by closing accounts.
If you need early wins to stick with it, the debt snowball method is a reasonable trade.
Tips that make it faster
- Ask for a lower rate on the top card. A lower APR on your target debt helps immediately. See how to lower credit card interest rates.
- Pay more than once a month if your issuer allows it. Many cards calculate interest on the average daily balance, so earlier payments can trim interest a little.
- Do not let promo rates lull you. Track the end date of any 0% offer.
Pair it with a lower APR
The avalanche gets cheaper still if you can replace the top rates with one lower one. A consolidation loan only helps when its APR, including fees, is clearly below your card rates.

Examples are illustrations, not offers. Approval and terms depend on the lender, your state and your credit profile.
Frequently asked questions about debt avalanche method: pay less interest on your debt
How much does the avalanche method save?
It depends on how far apart your rates are. In our three-debt example with $500 a month, the avalanche saved about $364 compared with the snowball. With bigger balances or wider rate gaps the savings grow.
What if my highest-APR debt is also my biggest?
That is when the avalanche feels slow, because the first payoff can take a long time. Track the falling balance each month, or try to lower that card's rate with a balance transfer or consolidation loan.
Do promotional 0% balances go last?
Yes, while the promo lasts. Note when it ends. Before the regular rate kicks in, that balance may move up the list.
