About Debt Snowball Payoff Calculator

The snowball method pays the minimum on everything and throws all spare cash at the smallest balance first. It is not the cheapest order, but clearing a debt early is a strong motivator and the freed payment rolls onto the next debt.

Formula

Pay interest on all debts, direct surplus to the smallest balance, then roll that payment onward

Frequently Asked Questions

Is snowball worse than avalanche?

Slightly more expensive when rates differ, but the quick first win improves the odds of sticking with the plan.

What if the budget barely covers interest?

Then progress stalls. Cut costs or negotiate rates before choosing a payoff order.
