Debt & Credit
Payoff plans, interest cost and credit card minimums. 20 free tools, each one showing the math behind its answer and running entirely in your browser.
Debt tools answer two questions: how long this takes, and what the interest costs while it takes that long. Both numbers are printed, because a payoff date without its interest bill hides the only reason to pay early.
The payoff planners model minimum payments, extra payments and the two classic orderings - smallest balance first, or highest rate first - as separate options rather than one blended answer, because they disagree exactly when a big balance and a high rate are not the same account.
Each page says what it does not model: new spending on the card, a promotional rate that ends, or an issuer that changes how the minimum is computed. Those three are the usual reason a real payoff date drifts from a planned one.
Every calculator in this category runs entirely in your browser and is an estimate tool, not debt, financial or credit advice: no page here promises a forgiven balance, a higher score or approval — those numbers come from your issuer and lender, not from arithmetic.
