What changes this most?
A higher fixed payment shortens the payoff period and reduces interest because principal falls faster.
Sensitivity check
A roughly 10% move in fixed monthly payment changes the modeled headline result by up to 5 months in this setup.
Assumes the APR and payment stay constant and no new spending is added.

Formula
Interest is added monthly at APR ÷ 12, then the fixed monthly payment is applied until the balance reaches zero.
Adjust one assumption at a time to understand which inputs have the greatest effect. Compare several realistic scenarios rather than relying on a single projection.
Default assumptions are maintained by FinTrex and may not reflect current products or rates available to you. Review every input before using the estimate.
