What is the Credit Cards Payoff Calculator doing with my numbers?
In plain language: The calculator converts APR to a monthly rate, adds monthly interest, subtracts the base payment plus extra payment, and repeats until the combined balance is paid off. 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 combined-balance estimate. It does not model daily balances, separate APR tiers, fees, promotional APRs, minimum-payment changes, or new purchases. Real finance decisions can also depend on fees, timing, local rules, credit details, and provider-specific terms.
