AI explanation

Formula

Pays minimums on all debts, directs any extra budget to the smallest-balance debt first; once paid off, its minimum rolls into the extra budget for the next-smallest debt

Assumptions

  • Enter balances, rates, and minimum payments in the same order — they're matched positionally.
  • The snowball method prioritizes quick psychological wins (paying off smaller debts sooner) over minimizing total interest — see the Debt Avalanche Calculator for the interest-minimizing approach.

Frequently asked questions

What is the debt snowball method?

A payoff strategy that targets your smallest-balance debt first with any extra payment budget, while paying minimums on everything else — once the smallest is cleared, its minimum payment rolls into attacking the next-smallest debt, building momentum.

Why choose snowball over avalanche if it's not mathematically optimal?

Snowball's quick wins (clearing small debts fast) can provide motivation and a sense of progress that keeps people committed to their payoff plan — behavioral research suggests this matters as much as pure interest savings for many people.

How much more interest will I pay with snowball vs avalanche?

It depends on your specific debts — the difference is usually modest when debts are similar, but can be significant when a high-rate debt has a large balance and gets deprioritized under snowball. Compare both calculators for your actual numbers.
