The debt avalanche method targets your highest-rate debt first

A repayment strategy designed to reduce your total interest costs.

Which debt gets extra money firstWhy the first payoff may take timeWhen another debt needs attention first

Direct answer

The debt avalanche method puts extra payments toward your highest-rate debt first.

You pay at least the minimum on every debt, then send any extra payoff money to the one with the highest interest rate. Once that debt is gone, you move its full payment to the next-highest-rate debt. This order may reduce total interest, but a large first balance can take time to clear.

Why people use the debt avalanche method

Three reasons this strategy exists.

Less interest paid

With the same payment budget, targeting the highest rate first generally reduces interest compared with paying a lower-rate debt first.

A clear order

Interest rates tell you where each extra dollar goes, so you do not have to pick a new target each month.

No new loan

You can use this approach on debts you already owe without applying for a new loan or moving balances.

Could It Fit Your Needs?

This strategy earns a place on your list when these things are true.

You can cover every minimum

The plan only works if you keep all accounts current while putting extra money toward one debt.

You have money left over

Even a modest amount above your minimums gives you a payment to direct toward the highest-rate balance.

You can wait for a win

If your highest-rate debt has a large balance, you may make progress for months before any account is paid off.

Think Twice If…

Any one of these can change the decision.

Minimums are out of reach
Putting extra money toward one debt while missing another payment can bring added costs; address the payment shortfall first.
An account needs urgent attention
Past-due amounts or a promotional deadline may cost you more if ignored; check those terms before following the rate order.
You need an early payoff
A large first balance could sap your drive to continue; the debt snowball may suit you better.

What to Expect

Four stages, start to finish.

1
List each debt
Write down each balance, interest rate, minimum payment, and any deadline that could change what you owe.
2
Cover the minimums
Pay at least the required amount on every account before setting aside extra money for payoff.
3
Target the highest rate
Send all extra payoff money to the debt with the highest rate, even if its balance is larger.
4
Move the full payment
Once that debt is paid off, put its full payment toward the next-highest-rate debt.

Less interest may mean a longer wait for a first payoff

Each gain here comes with something you hand back.

You get

Targeting the highest rate may reduce total interest when you keep the same payment budget.

You give up

If that balance is large, your first paid-off debt may come later than it would with the snowball.

You get

Paying every minimum keeps your other debts current while you focus extra money on one.

You give up

Those required payments leave less of your budget for the debt you are trying to clear first.

You get

You can start with the accounts you have, without taking out a new loan.

You give up

Changing the payment order does not lower your rates; interest still adds up on unpaid balances.

What to Compare

Five things that move the value of this strategy.

Check	Why it matters
Interest rate on each debt	The current rates set the usual payment order, so check them again if a rate changes.
Minimums and affordable extra payment	Add up every required payment first, then choose an extra amount your monthly budget can support.
Balance of the first debt	A large highest-rate balance can delay your first payoff, even while your payments reduce what you owe.
Promotional and deferred-interest deadlines	A deadline may make another balance more urgent, depending on what its terms charge if you miss it.
New charges on each account	New borrowing adds to your balances and may slow payoff, even if you keep following the rate order.

Your plan checks whether it fits and shows the options that match.

Good to Know

Does a larger balance change which debt comes first?+

Not under the usual rate order. In an illustrative example, you have a $2,000 higher-rate card, a $500 lower-rate card, and $100 extra each month. The extra $100 goes to the $2,000 card, despite its larger balance. You still pay both minimums.

How does the debt avalanche compare with the snowball?+

The avalanche targets the highest rate; the snowball targets the smallest balance. The snowball may give you a first payoff sooner, but it can cost more interest if a higher-rate debt stays unpaid longer. Either plan depends on making the payments and sticking with it.

What if a debt's interest rate changes?+

Check your rates again and adjust which debt gets the extra payment if needed. First, review any promotional or deferred-interest terms. A deadline may matter more than the new rate order.

What if two debts have the same interest rate?+

Either can receive your extra payment based on its rate. You might choose the smaller balance for an earlier payoff, after checking whether either debt has a deadline or other term that needs attention.

Can I keep using a card while paying it down?+

You can, but new charges can offset your payments and extend the time it takes to clear the balance. If you can avoid adding to the debt, more of each payment can go toward what you already owe.
