Credit Card Payoff Calculator

What this credit card payoff calculator does

This credit card payoff calculator shows how long it takes to eliminate a revolving balance with a fixed monthly payment plus any extra amount you add each month. It totals interest paid over the life of the payoff and compares alternative payment levels so you can see the real cost of paying only the minimum versus accelerating debt reduction.

How payoff math works

Each month, interest accrues on the remaining balance at your APR divided by 12. Your payment first covers that interest; the remainder reduces principal. The calculator iterates month by month until the balance reaches zero, summing interest along the way. If your payment does not exceed the first month's interest charge, the balance never shrinks—the tool warns you when that happens.

Understanding each input

• Current balance: Total owed today, including purchases already on the statement.
• APR: Annual percentage rate on purchases; cash-advance or penalty rates may differ.
• Monthly payment: Fixed amount you plan to send every month.
• Extra monthly payment: Additional principal on top of the base payment—modeling a side-hustle allocation or budget trim.

Strategies that shorten payoff time

Even modest extra payments compound into large interest savings on high-APR cards. Before adding new debt, compare an auto purchase with the auto loan calculator—installment APR is often lower than revolving credit. If monthly obligations are stacking up, a debt-to-income ratio calculator reveals whether lenders would view your budget as stretched.

Once cards are under control, redirect the same payment into long-term growth with a compound interest calculator to see what those dollars could earn instead of feeding interest charges. Self-employed readers should also account for quarterly taxes via a self-employment tax calculator so debt payoff does not crowd out required IRS deposits.

Common mistakes

• Paying only the statement minimum while continuing to charge new purchases.
• Ignoring promotional rate expirations that snap back to a much higher APR.
• Assuming balance-transfer fees and new-card annual fees are negligible.
• Stopping extra payments after a few months instead of automating them.

When fixed-payment math does not apply

Minimum payments that shrink as the balance falls, variable rates tied to prime, and cards with separate buckets for purchases versus cash advances require lender statements—not a single-formula estimate. Use this page for planning fixed-payment scenarios; reconcile with your issuer's payoff disclosure for binding numbers.

FAQ

Should I pay off cards or invest? Guaranteed "return" from eliminating 20%+ APR debt usually beats uncertain market gains for most households—run both scenarios before deciding.

Does this include balance transfer offers? No. Model 0% promo windows separately and add transfer fees to your true cost.

When consult a professional? A certified credit counselor or bankruptcy attorney can help when payments cannot exceed interest, accounts are in collections, or you need a structured debt-management plan.
