よくある質問

Why is avalanche usually cheaper than snowball?
By targeting the highest interest rate first, less total interest accrues over time compared to prioritizing by balance size, even though both methods use the same total payment amount.
How is the minimum payment on each debt determined?
It is estimated as the greater of 2% of the balance or a $25 floor, applied to every debt each month.
What inputs does the Debt Avalanche Calculator need?
You'll need to provide: Balances (comma separated), Rates % (comma separated, same order), Extra monthly payment. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Debt Avalanche Calculator?
The Debt Avalanche Calculator applies the formula exactly as calculated — Each month, minimum payments are made on every debt while extra payment is directed to the debt with the highest interest rate; once it's paid off, its former payment rolls into the next-highest-rate balance, and so on until all debts are cleared. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Are these results guaranteed?
No. The Debt Avalanche Calculator gives an estimate based on the numbers you enter and standard financial formulas — actual rates, fees, taxes, and terms vary by lender, institution, and jurisdiction, and can change over time. This is not financial advice; consult a qualified financial professional for decisions specific to your situation.
