Credit Card Payoff Calculator

Enter each card's balance, APR and minimum payment, add whatever extra you can afford, and compare the debt snowball against the debt avalanche.

You get the payoff date, total interest and payoff order for both methods, so you can see exactly what the cheaper ordering is worth. Everything runs in your browser and nothing is stored.

Both lines start at the same total. The avalanche pulls ahead because less of each payment is lost to interest.

Snowball vs avalanche, in plain terms

Both methods pay the minimum on every card and send one extra amount at a single target card. The only difference is which card gets targeted first.

  1. 1. Snowball targets the smallest balance. The first card disappears quickly, and its payment rolls into the next one. Cheapest in willpower, slightly more expensive in interest.
  2. 2. Avalanche targets the highest APR. Your most expensive interest stops accruing first, which always costs the least overall — but the first payoff can feel slow.
  3. 3. The extra payment does the real work. Minimums are often close to the monthly interest, so the money above the minimum is what actually shrinks the balance.
  4. 4. Rolling payments accelerate everything. Each cleared card frees its payment for the next, so the last balances fall far faster than the first.
