Why the avalanche works
The debt avalanche method prioritizes the balances with the highest annual percentage rates first. This approach reduces the cost of borrowing fastest and can save the most interest over time.
Each month, minimum payments are covered first, then extra cash is directed toward the highest APR debt. Once a balance is paid off, the freed-up payment is applied to the next highest interest account.
This strategy is especially effective when debt balances are high and interest rates differ meaningfully across accounts. It is a strong option for borrowers seeking the lowest total interest cost.
- Highest APR debts get attacked first.
- Interest costs are reduced faster.
- Extra cash flows are used most efficiently.
- It emphasizes total-cost savings over emotional momentum.
Frequently asked questions
What is the debt avalanche method?
It prioritizes paying off the balance with the highest APR first while making minimum payments on the others.
How is it different from snowball?
Snowball focuses on the smallest balance first, while avalanche focuses on the highest interest rate first to reduce total interest.
Is this a guaranteed payoff plan?
No. This is an estimate built from your inputs and assumes fixed APRs, consistent monthly payments, and no late fees.
Should I include every debt?
Yes, when comparing payoff strategies, include all balances you intend to pay off in the plan.
Does it consider account fees?
No. This estimate focuses on principal, APR, minimum payments, and additional monthly funds.
