How it works

Snowball means you pay minimums on all debts, then apply your extra amount to the smallest balance first. When that debt hits $0, its payment (minimum + extra) “rolls” to the next smallest balance.

Is snowball or avalanche better?

Avalanche usually minimizes interest. Snowball can be easier to stick with. The best method is the one you’ll follow consistently.

Does this include new purchases?

No. It assumes you stop adding new charges and make consistent payments.

Why might results differ from my statement?

Lenders can vary by daily interest, statement timing, rounding, and fees. This is a planning estimate.
