Frequently Asked Questions

What is the debt snowball method?

The debt snowball method involves paying off your smallest debt first, then rolling that payment into the next smallest. It builds momentum and motivation, though the debt avalanche (highest interest first) saves more in interest.

How much can extra payments save?

Even an extra $50–100 per month on a debt can save hundreds or thousands in interest and shave years off your payoff date. Use this calculator to see the exact impact.

What is the debt avalanche method?

The debt avalanche targets the highest-interest debt first, minimizing total interest paid over time. It is mathematically optimal but can feel slower than the snowball method.
