Debt snowball vs. debt avalanche
Both approaches keep making payments on all active debts while directing extra payment capacity toward one balance at a time. The difference is which balance gets priority.
Debt snowball
The snowball method prioritizes the smallest balance first. Once that balance is paid, its payment capacity rolls to the next-smallest balance. The appeal is visible progress: individual balances can disappear sooner.
Debt avalanche
The avalanche method prioritizes the highest APR first. Because higher-rate debt is targeted earlier, avalanche often produces a lower estimated interest cost when all other inputs stay the same.
What this calculator assumes
The estimate applies the APRs and payment amounts you enter on a monthly basis. It assumes no new charges, fees, promotional-rate changes or missed payments. Real lender calculations, statement cycles and minimum-payment formulas can differ.
