Minimum to cover all payments: $550

Avalanche saves you $445 in interest

Paying highest-APR debts first (avalanche) clears everything costs less in interest. Snowball (smallest balance first) can be easier to stick with.

Balance over time

Interest accrues monthly on each balance. Estimates assume fixed APRs and a constant monthly budget, and don't include fees or promotional rates. For planning only.

How it works

Both methods pay the minimumon every debt each month, then throw whatever budget is left at one “focus” debt. When that debt is gone, its payment rolls into the next one — the snowball effect. The only difference is which debt you focus on:

  • Avalanche targets the highest interest ratefirst. This always costs the least interest and is usually the fastest — it's the mathematically optimal order.
  • Snowball targets the smallest balance first. You clear individual debts sooner, which many people find more motivating even if it costs a little more interest overall.

Example: with a $6,000 card at 22%, a $12,000 car loan at 6.5%, and a $4,000 personal loan at 12% on an $800/month budget, avalanche attacks the 22% card first and typically saves a few hundred dollars in interest versus snowball, which would clear the $4,000 loan first. Adjust the numbers above to see your own gap.

FAQ

Avalanche (highest interest rate first) always costs the least interest and is usually fastest, so it's the mathematically optimal choice. Snowball (smallest balance first) clears individual debts sooner, which can be more motivating. If the interest difference between them is small, the best method is simply the one you'll actually stick with.
