The Real Cost of Carrying a Balance
This tool estimates two things that matter most when you carry a balance: how many months it will take to reach a zero balance, and how much you'll pay in interest along the way. You enter your current balance, your card's annual percentage rate (APR), and the fixed amount you plan to pay each month. The calculator then simulates your account month by month and reports the payoff date, the total interest paid, and a schedule showing how the balance shrinks over time.
How Minimum Payments, APR, and Extra Payments Interact
Credit card interest is charged on the balance you still owe, and it is usually compounded each billing cycle. The math behind each month is simple: the calculator converts your APR into a monthly periodic rate (the APR divided by 12), multiplies that rate by your current balance to find the interest charge, adds that interest to the balance, and then subtracts your payment. Whatever is left over rolls into the next month and accrues interest all over again.
This is why minimum payments stretch payoff out so far. A minimum payment is typically set at a small percentage of the balance plus interest, so a large share of each payment is consumed by the finance charge and only a sliver reduces the principal. Three levers change the outcome:
- Balance: a larger starting balance means more interest accrues each month, so more of every payment is eaten by interest before it touches principal.
- APR: a higher rate increases the monthly finance charge. Even a few points lower can shave months off the schedule and cut total interest noticeably.
- Monthly payment: every dollar above the interest charge attacks the principal directly. Because the balance falls faster, future interest charges fall too, which compounds in your favor.
Example: $6,000 at 20% APR
Suppose you owe a hypothetical $6,000 on a card at a hypothetical 20% APR. The monthly periodic rate is 20% divided by 12, or about 1.667%. In the first month, interest is roughly $100 (1.667% of $6,000). If you pay $150, only about $50 reduces the principal, leaving a balance near $5,950. Now imagine you pay $400 instead. Interest is still about $100, but $300 goes to principal, dropping the balance to about $5,700. The larger payment doesn't just finish sooner; it lowers next month's interest, so the gap between the two scenarios widens every single month. These are illustrative figures, not your actual numbers.
How to Read Your Results
Two outputs deserve your attention. The months to payofftells you how long the current plan takes, and the total interest shows what the debt costs you on top of what you borrowed. Watch how both numbers move as you raise the monthly payment: small increases often cut months and interest by a surprising amount, because reducing the balance faster shrinks every future interest charge. The balance schedule then shows that decline month by month, so you can see the turning point where principal starts falling quickly.
Strategies to Pay Off Debt Faster
The most reliable lever is paying more than the minimum, consistently. Pick a fixed monthly amount you can sustain and automate it so you don't backslide. If you carry several cards, two ordering strategies are popular:
- Avalanche: direct extra dollars to the highest-APR card first. This minimizes total interest and is mathematically optimal.
- Snowball: direct extra dollars to the smallest balance first. You eliminate accounts quickly, which can keep you motivated even though it may cost slightly more in interest.
When to Consider a Balance Transfer
If your credit is strong, a promotional 0% APR balance transfer can pause interest for a fixed window, letting your full payment hit the principal. Weigh the one-time transfer fee against the interest you would otherwise pay, and have a plan to clear the balance before the promotional period ends and the standard rate returns.
Tools for Other Kinds of Debt
This calculator assumes you stop adding new charges and keep paying a steady amount. If you're instead weighing a fixed-term personal loan to consolidate the debt, our Loan Calculator models a set repayment schedule, and the Amortization Calculator breaks down principal versus interest for any installment loan. Use those when the debt has a defined term rather than a revolving balance.
Frequently Asked Questions
Why does my credit card take so long to pay off?
Interest is charged on your remaining balance every billing cycle, so when you pay only the minimum, much of the payment covers the finance charge and only a little reduces the principal. The smaller your payment relative to the balance and rate, the longer the schedule stretches. Paying a higher fixed amount sends more to principal, which lowers future interest and shortens the payoff dramatically.
What is the minimum payment trap?
Issuers typically set the minimum at a small percentage of the balance plus accrued interest, or a fixed floor amount. Because that minimum shrinks as the balance shrinks, paying only the minimum can keep you in debt for many years and pile up substantial interest. Committing to a fixed dollar payment above the minimum, rather than a moving percentage, keeps your progress steady.
How does this calculator handle interest?
It converts your APR into a monthly periodic rate by dividing the APR by 12, then applies that rate to your balance each month to find the interest charge before subtracting your payment. The leftover balance carries into the next month and accrues interest again. This month-by-month simulation produces your estimated payoff time, total interest, and balance schedule.
Should I pay off high-interest or small balances first?
The avalanche method targets the highest APR first and saves the most money mathematically. The snowball method targets the smallest balance first and delivers quick wins that help many people stay motivated. Both eventually clear the debt. If you carry a single balance, focus on the highest fixed payment you can sustain and let this tool show the impact.
How can I lower my credit card interest rate?
Options include asking your issuer for a lower rate, moving the balance to a promotional 0% APR transfer card, consolidating into a fixed-rate personal loan, or working with a reputable non-profit credit counseling agency. Lowering the rate reduces the monthly finance charge, so more of each payment reaches the principal and the payoff period gets shorter.
Does a balance transfer always save money?
Not always. A promotional 0% APR transfer pauses interest, but most cards charge a one-time transfer fee, often a few percent of the amount moved. The transfer pays off when the interest you would have accrued exceeds that fee and you clear the balance before the promotion ends. If the standard rate returns while a balance remains, the savings can shrink quickly.
What happens if I keep adding new charges?
This calculator assumes you stop adding to the balance and pay a steady amount. New purchases raise the balance and the interest charged on it, which offsets your payments and pushes the payoff date further out. To make real progress, it helps to pause new spending on the card you are trying to eliminate until the balance reaches zero.
