Debt Snowball vs Avalanche: Which Method Saves More Interest?

Summary. If you have several debts, keep making every required minimum payment, then direct the extra money either to the highest-rate debt (the “avalanche”) or to the smallest balance (the “snowball”). The first usually reduces interest cost; the second delivers the motivational win of closing an account sooner.

Published and data checked: 29 October 2026. The figures below are an educational example, not individual credit or legal advice. Your contract rates, fees and repayment rules may differ.

First, protect every required payment

Before choosing a method, list each balance, annual interest rate, required minimum, due date and possible penalties in one table. With either method, you pay all minimums first; only the extra amount goes to the priority debt.

The Central Bank of Armenia’s consumer information says a credit history includes loans, payment performance, overdue amounts and related penalties. It advises making repayments on time and avoiding even a one-day delay. Neither strategy is therefore a reason to skip another debt’s minimum.

Two methods, one key difference

Avalanche: put extra money toward the highest interest rate. When it is repaid, roll the whole freed payment into the next-highest-rate debt. This is usually the mathematically cheaper route.
Snowball: put extra money toward the smallest balance regardless of its rate. Closing the first debt quickly may help motivation, but total interest can be higher.

The U.S. Consumer Financial Protection Bureau (CFPB) presents the same two approaches: the highest-rate method may save money over time, while the snowball offers visible progress sooner.

Example: AMD 1,050,000 of total debt

Assume three debts:

A: AMD 150,000 at 18% a year, AMD 10,000 minimum,
B: AMD 300,000 at 30% a year, AMD 15,000 minimum,
C: AMD 600,000 at 24% a year, AMD 20,000 minimum.

The fixed monthly repayment budget is AMD 70,000. Minimums total AMD 45,000, leaving AMD 25,000 each month for the priority debt. The model adds interest monthly at annual rate/12 and pays at month-end. It excludes fees, insurance and penalties.

Snowball: A → B → C. A is cleared in month 5 and all debt in month 19. Approximate interest: AMD 222,519.
Avalanche: B → C → A, following rates of 30%, 24% and 18%. B is cleared in month 9 and all debt in month 19. Approximate interest: AMD 211,645.

In this simplified example, the avalanche saves about AMD 10,874 in interest even though both plans finish in 19 months. Actual results can change because of daily interest, changing minimums, fees, grace periods and early-repayment terms.

A six-step practical plan

Collect the latest statements. Do not rely on memory; record the exact balance and contract rate.
Set a safe monthly budget. It must cover every minimum without sacrificing food, utilities or medicine.
Choose one method for at least three months. Snowball may suit a motivation problem; avalanche suits a cost-saving goal.
Automate minimums. Keep a small account buffer so a technical shortfall does not occur on the due date.
Roll every cleared payment into the next debt. Do not reduce the AMD 70,000 monthly budget merely because one debt is gone.
Update the table monthly. Compare actual interest and balances with your estimate.

If you can no longer make the minimum

Then snowball versus avalanche is secondary. Contact the creditor before delinquency and ask in writing about restructuring, a due-date change or other options, including their full cost. Do not stop paying merely because an intermediary promises to “erase” debt. The CFPB warns that debt-settlement services can lead to more fees, interest and credit damage.

If you have a dispute with a financial institution, first submit a written complaint to the institution. The official Financial System Mediator page says applicants should first complain to the institution and obtain its response; the Mediator’s service is free.

What this means for the reader

If you can keep the same monthly budget, avalanche is usually the best starting point for saving interest. But a perfect calculation you abandon is worse than a simple plan you follow. Pick one rule, protect every minimum, and compare the real result after three months.
