Two strategies, one honest comparison: how many months, how much interest, and which one wins for your debts.

What's inside

SNOWBALL AND AVALANCHE, SIDE BY SIDESame debts, two payoff orders: smallest balance first vs highest rate first. Both simulated month by month for up to 84 months.
THE COMPARISON PAGETotal interest, months to debt-free, and the difference between the two in dollars. One line answers the question every article argues about.
MONTH-BY-MONTH SCHEDULEEach strategy shows which debt gets the extra payment in which month, and the running balance, so you can see the plan instead of trusting it.
DASHBOARDTotal debt, monthly minimums, payoff date and interest saved.

Who it's for

Anyone with 2-8 debts (cards, loans, car finance) deciding between snowball and avalanche.

How it works

  1. Enter each debt: balance, rate, minimum payment.
  2. Enter what you can pay extra each month.
  3. Open Compare: months, interest, and the winner.
