Strategy comparison
Add your cards above to compare payoff strategies.
Simplified model: minimums assumed 2% of balance (min $/₹/₨ 25 equivalent); your full budget goes to the target card, minimums to the rest. Actual cards vary — check your statements.
Avalanche (highest APR first) always costs less in total interest. Snowball (smallest balance first) clears a whole card sooner, which motivates many people to stick with the plan. The calculator shows both — pick the one you'll actually follow.
One extra payment changes everything
On a $5,000 balance at 24% APR, paying $100/month takes 9+ years and costs ~$5,800 in interest. Paying $200/month clears it in under 3 years with ~$1,600 interest. Small increases in your monthly budget create huge savings.
FAQs
What is the avalanche vs snowball debt payoff method?
Avalanche: pay the highest-interest debt first — saves the most money. Snowball: pay the smallest balance first — gives quick wins that keep you motivated. Both work; avalanche is mathematically cheaper.
How long will it take to pay off my credit card?
It depends on your balance, interest rate, and monthly payment. Add your cards above — the calculator shows your exact debt-free date and total interest for each strategy.
Should I pay only the minimum on my credit card?
Minimum payments keep you in debt for years and cost far more in interest. Paying even a little extra each month can cut years off your payoff time.
Is this credit card payoff calculator free?
Yes. It is 100% free with no signup required.
What is a balance transfer, and is it worth it?
You move existing debt to a card offering 0% intro APR — usually for 12–21 months, with a 3–5% transfer fee. It's worth it if you can clear the balance before the intro period ends; any remainder jumps to a high standard rate, so have a payoff plan first.
Will paying off my credit card hurt my credit score?
No — paying down balances lowers your credit utilization ratio, which typically raises your score. Keep the account open afterward: an old, unused credit line lengthens your credit history and helps your score further.
Should I save money or pay off credit cards first?
Pay the cards first, keeping only a small emergency buffer of around $500–1,000. Card interest at 20%+ dwarfs any savings-account return, so every dollar thrown at the balance earns a guaranteed high 'return' no savings product can match.
How credit card payoff math works
Each month, your card issuer adds interest = balance × APR ÷ 12, then subtracts your payment. Minimum payments are engineered to barely exceed the monthly interest — so the balance shrinks at a glacial pace while interest compounds against you. Paying more than the minimum is the entire game: every extra dollar skips all the future interest it would have accrued.
The payoff-time formula: n = −ln(1 − rB/P) ÷ ln(1+r), where B = balance, r = monthly rate (APR ÷ 12), P = monthly payment. It only works when P > rB — i.e., your payment exceeds the monthly interest charge. Total interest = P × n − B.
Worked example: a $4,000 balance at 22% APR, paying $150/month. Monthly rate r = 0.22 ÷ 12 = 0.01833; first month's interest = $73.33 — nearly half the payment. n = −ln(1 − 0.01833×4000÷150) ÷ ln(1.01833) = −ln(0.511) ÷ 0.01817 ≈ 37 months; total paid ≈ $5,500, meaning ~$1,500 in interest. Raise the payment to $200 and it drops to ≈ 26 months and ~$1,050 interest — $50/month extra saves $450 and nearly a year.
Practical tips: the avalanche method (highest APR first) is mathematically cheapest; the snowball (smallest balance first) wins on motivation — pick the one you'll actually stick with. Never pay only minimums. Limitation: the math assumes no new spending and a fixed APR; new purchases and penalty rates change everything.
The minimum-payment trap, quantified: many cards set the minimum at ~2% of the balance (or $25, whichever is higher). On that $4,000 / 22% APR balance, the first minimum is just $80 — barely above the $73.33 monthly interest. Paying only minimums stretches payoff to 20+ years with total interest exceeding $5,000 — you pay more in interest than the original debt. This is by design: minimums maximize lender profit while keeping you technically "current." The escape math: every dollar above the minimum attacks principal directly, and principal destroyed early never accrues interest again — that's why raising payments from $150 to $200 (a 33% increase) cut 11 months and $450 of interest. If you can't raise payments, a balance transfer to 0% APR for 18 months with a 3% fee ($120 on $4,000) beats paying 22% on the full balance — provided you actually pay it down during the intro window instead of spending the "savings."
