What does it mean if my payment can never pay off the balance?

If your fixed payment is less than or equal to the interest charged each month, the balance never shrinks — it can even grow. You'll need to increase the monthly payment above that threshold for the balance to actually go down.

Does this account for new purchases on the card?

No — it assumes no new charges are added and the full payment goes toward the existing balance each month. New spending will extend the payoff time beyond what's shown here.

Why does credit card interest add up so quickly?

Credit card APRs are typically much higher than other forms of debt, and interest compounds on the remaining balance each month — a combination that can make a balance grow rapidly if payments only barely cover the monthly interest charge.

Should I pay more than the fixed amount if I can afford to?

Yes — any extra payment above your planned fixed amount goes directly toward reducing principal, which shortens your payoff time and reduces total interest paid, often significantly for high-APR cards.

How does this differ from just paying the minimum payment listed on my statement?

Minimum payments are usually calculated as a small percentage of the balance and shrink over time as the balance decreases, extending payoff time substantially — this calculator instead assumes a fixed dollar amount every month, which tends to pay off the balance faster.
