Payoff Summary
Why Minimum Payments Are a Trap
A $5,000 balance at 22.99% APR with minimum 2% payments would take over 30 years to pay off and cost more than $8,000 in interest — nearly doubling the original debt. The minimum payment barely covers the monthly interest, with almost nothing reducing the principal.
Paying just $50 more per month than the minimum can cut years off your timeline and save thousands. The "Fixed Payment" mode shows this comparison instantly.
Everything About the Credit Card Payoff Calculator
The math behind credit card interest, how snowball and avalanche strategies differ, and the fastest path to zero debt.
How It Works
- Enter your current card balance and APR
- Set your planned monthly payment
- Optionally add an extra payment amount
- See exact payoff date and total interest charged
- Compare scenarios to find your optimal payoff speed
The Formula
Monthly interest = Balance × (APR ÷ 12)
Months to payoff = −ln(1 − B × r ÷ P) ÷ ln(1 + r)
B = balance · r = monthly rate · P = monthly payment. Interest saved = Standard total − Accelerated total.
Pro Tips
- Even $25–$50 extra per month eliminates months of payments and significant interest
- Avalanche method: throw extra at highest-APR card first — saves the most total money
- 0% balance transfer offers: transfer high-APR debt and pay purely principal for 12–21 months
- Call your issuer requesting a rate reduction — about 30% of people who ask get approved
Frequently Asked Questions
What's the difference between debt avalanche and debt snowball? +
The avalanche method targets the highest-interest debt first — minimizing total interest paid over time. The snowball method targets the smallest balance first, regardless of interest rate — providing motivational wins that build momentum. Mathematically, avalanche saves more money. Psychologically, snowball may be better for people who need encouragement to stay on track. Research shows that for people who struggle with motivation, the behavioral benefit of snowball often outweighs the mathematical cost.
How does credit card interest actually compound? +
Credit cards calculate interest daily: daily periodic rate = APR ÷ 365, applied to your average daily balance. This interest accrues and is then added to your principal balance at month end (capitalization). The following month, you owe interest on the original balance plus last month's unpaid interest — true compounding. At 22% APR, your daily rate is 0.0603%. On a $5,000 balance, that's about $3 in interest every single day you carry the balance.
What is a balance transfer and when does it help? +
A balance transfer moves high-APR debt to a new card offering 0% intro APR — typically for 12–21 months. You pay a transfer fee (usually 3–5% of the amount). This makes sense when: you can realistically pay off the balance during the promo period, the transfer fee is less than the interest you'd pay, and you won't use the old card irresponsibly. Warning: if you don't pay off the balance before the promo ends, the remaining amount gets hit with the card's regular high APR immediately.
Should I pay off debt or invest first? +
General rule: if debt APR exceeds your expected investment return, pay off debt first. At 22% APR, paying off a credit card is a guaranteed 22% return — better than almost any investment. Always contribute enough to capture employer 401k matching first (it's an instant 50–100% return). After capturing the match: pay off high-interest debt (>7–8% APR), then invest. Low-interest debt like mortgages (<4–5%) can be paid on schedule while investing the difference.
How do minimum payments trap you? +
Minimum payments are typically 1–2% of your balance or $25 (whichever is higher). As your balance decreases, so does the required minimum payment. This creates a self-perpetuating trap: each month you pay less, which means less goes to principal, which keeps the balance high, which generates maximum interest for the lender. Credit card companies are legally required to show on your statement how many years it takes to pay off the balance making only minimums — read this number and use it as motivation to pay more.
