Before you rely on this result

Snowball or avalanche?

The debt snowball method pays the smallest balance first. It can create faster early wins, which helps some people stay consistent. The debt avalanche method pays the highest interest rate first. It often saves more money because expensive debt gets attacked earlier.

This calculator is an estimate. It assumes fixed monthly payments, fixed annual interest rates, monthly interest calculation, no late fees, and no new charges. Real lender calculations can differ because of daily interest, payment posting dates, promotional rates, fees, and rate changes.
