What is the Credit Card Calculator doing with my numbers?
In plain language: The calculator converts APR to a monthly rate, adds monthly interest and new charges, subtracts the monthly payment, and repeats until the balance reaches zero. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
What does this estimate leave out?
This is a simplified payoff estimate. It does not include fees, daily balance methods, variable APR changes, grace periods, minimum-payment rules, or issuer terms. Real finance decisions can also depend on fees, timing, local rules, credit details, and provider-specific terms.
