Perspective
Minimum payments stretch debt for years
Paying only the minimum can keep you in debt for a very long time because interest compounds on the balance.
A fixed amount above the minimum often collapses the payoff horizon dramatically.
FAQ
Common questions
How are minimum payments modeled?
Typically the greater of a small floor (e.g. $25) and a percent of balance plus interest — you can align inputs with your card’s disclosure.
Does this include new charges?
No. The calculator assumes you stop adding new balances for a clean payoff estimate.
