Minimum Payment

The minimum payment is the smallest amount a lender will accept each billing cycle without treating the account as delinquent. It is not the amount that pays off a balance quickly — it’s the floor, not a plan.

Why it isn’t fixed

On a typical revolving account (a credit card, most lines of credit), the minimum recalculates every cycle, commonly as something like the greater of a small percentage of the current balance or a flat dollar floor — say, whichever is larger of 1–2% of the balance or $25. Because the required minimum is tied to the balance, it falls as the balance falls. A $5,000 balance’s minimum might start near $145; the same account’s minimum on a $500 balance might have fallen to the $25 floor.

Installment debts — a car loan, a mortgage, most private and federal student loans — work differently: the payment is set by contract and stays fixed for the life of the loan (subject to its own terms), regardless of the declining balance.

Why this matters for how long payoff takes

A revolving balance paid at a declining minimum amortizes far more slowly than the same balance paid at a fixed amount equal to that first minimum — because the payment keeps shrinking exactly as the balance most needs a steady push. This is one of the most common misunderstandings in debt payoff math: “pay the minimum” does not mean “pay a fixed amount.”

What Kalco does with it

Kalco asks for the payment on your latest statement and, for revolving accounts, models the minimum as declining with the balance — not held flat — because that’s how most issuers actually calculate it. This isn’t your specific lender’s exact formula; see how credit card minimum payments actually work for the assumption in full and how much it can move a payoff date.
