Undebt.it Debt Payoff Calculator

Undebt.it is a fully customizable debt payoff planner that lets you choose your strategy or build your own. The standard options are snowball and avalanche, but you can manually arrange your payoff order if you prefer a hybrid approach or want to prioritize specific loans for your own reasons. It generates a month-by-month payment schedule and shows your total interest cost under each method.

The tool's strength is flexibility. Many calculators lock you into one method, but Undebt.it respects your judgment. You can use it to test an unconventional payoff order if you have personal reasons to prioritize certain loans differently. No account or signup is required, and the interface is straightforward enough for one-off planning.
