Avalanche and snowball methods optimize different goals. Avalanche usually targets interest savings; snowball may reduce account count sooner.

FAQ
Is the lowest payment always best?
No. A lower payment can increase total interest if the term is longer.
When does refinancing make sense?
Usually when interest savings exceed fees within the expected holding period.
Can a calculator decide for me?
No. It clarifies the numbers; the decision also depends on risk and preferences.
Named decision metrics
Debt decisions often compare APR, monthly payment, total interest, payoff date, balance-transfer fee, loan-to-value and break-even month. The best calculator page shows more than the lowest payment because term length can hide cost.
Concrete scenario
A balance transfer of 5,000 with a 3% fee costs 150 upfront. If it saves 40 per month in interest, simple break-even is 3.75 months. If the promotional rate ends after 12 months, payoff speed becomes part of the decision.
