Credit Card Calculator
Calculate how long it will take to pay off your credit card and how much interest you'll pay
How to Use This Credit Card Calculator
- Enter your current credit card balance
- Input your card's APR (find this on your statement)
- Choose your payment approach: fixed monthly amount or target payoff date
- Add any annual fee if your card charges one
- Click 'Calculate Payoff' to see your timeline and total interest
- Use the comparison tab to evaluate balance transfer options
Example: A $5,000 balance at 22.99% APR with $200 monthly payments: payoff in 32 months, $1,356 in total interest. Paying just the $100 minimum? That stretches to 9+ years and $7,500+ in interest—you'd pay more than double your original balance.
Tip: Every $50 extra per month dramatically cuts your payoff time. Going from $150 to $200 on a $5,000 balance can save you a full year and hundreds in interest.

Understanding Your Results
Focus on total interest paid and time to payoff. These numbers reveal the true cost of carrying credit card debt.
| Result | Meaning | Action |
|---|---|---|
| Payoff under 12 months | Manageable debt | Stay aggressive—you're close to freedom |
| Payoff 12-24 months | Significant debt | Consider balance transfer to 0% APR card if you qualify |
| Payoff 24-48 months | Heavy debt burden | Evaluate debt consolidation loan at lower rate |
| Payoff 48+ months | Debt emergency | Seek credit counseling or consider aggressive measures |
Meaning: Manageable debt
Action: Stay aggressive—you're close to freedom
Meaning: Significant debt
Action: Consider balance transfer to 0% APR card if you qualify
Meaning: Heavy debt burden
Action: Evaluate debt consolidation loan at lower rate
Meaning: Debt emergency
Action: Seek credit counseling or consider aggressive measures
Note: If your minimum payment barely covers the interest, you're in a debt trap. Any payment increase will have an outsized impact.
About Credit Card Calculator
Formula
Monthly Interest = (APR / 12) × Balance Interest is technically calculated daily (APR / 365 × Balance × Days), then charged monthly. Each payment first covers accrued interest; only the remainder reduces principal.
Current Standards: Average credit card APR in 2026: 22.77%. 0% intro APR offers typically last 15-21 months. Balance transfer fees: 3-5% of transferred amount.
Frequently Asked Questions
Why does paying the minimum take so long?
Minimum payments are designed to keep you in debt. On a $5,000 balance at 22% APR, a 2% minimum starts at $100 and decreases as your balance drops. Most of that $100 goes to interest—only $8-10 reduces your principal in month one. As your balance and minimum payment shrink, you pay even less toward principal. This creates a payoff timeline of 15-20+ years.
Should I do a balance transfer?
A 0% APR balance transfer makes sense if: you can pay off the balance during the intro period (typically 15-21 months), the 3-5% transfer fee is less than the interest you'd otherwise pay, and you won't rack up new charges. Do the math: $5,000 transferred at 3% fee = $150 cost vs. $1,200+ in interest over 18 months at 22% APR. The catch—any balance remaining when the intro period ends faces the regular APR, often 20%+.
How does credit card interest actually work?
Credit cards use average daily balance and daily periodic rate. Your APR is divided by 365 to get the daily rate (22% APR = 0.0603% daily). Each day, that rate is applied to your current balance. If you pay in full by the due date, you pay zero interest. Carry any balance, and you lose the grace period—new purchases start accruing interest immediately, and you're charged for every day you carry a balance.
Which debt should I pay off first?
Mathematically, target the highest interest rate first (avalanche method)—credit cards typically beat all other debt. A $5,000 credit card at 22% costs $1,100/year in interest; a $5,000 car loan at 6% costs $300/year. Paying off the card first saves $800 annually. The snowball method (smallest balance first) works psychologically but costs more in interest. For credit cards specifically, always prioritize them over almost any other debt.
How do I avoid credit card debt in the future?
Treat credit cards like debit cards—never charge more than you can pay off that month. Set up autopay for the full statement balance. If you can't pay in full, stop using the card immediately and switch to cash/debit until it's paid off. Build a $1,000 emergency fund so unexpected expenses don't go on plastic. The goal is using cards for rewards and protection while never paying a cent in interest.
