Credit Card Payoff Calculator
Two-mode calculator. Mode A: enter a fixed monthly payment, see how many months until payoff and total interest. Mode B: enter a target payoff window, see what monthly payment you need. Both modes compare your custom plan against the disastrous 'minimum-only' path so you can see the cost of stretching it out.
Inputs Explained
- Balance: Your current credit-card balance.
- APR: The card's stated annual percentage rate; convert to monthly rate by APR/12.
- Mode: 'Months to payoff' (given a payment) or 'Required payment' (given a target months).
- Monthly Payment: Mode A only — your planned fixed monthly payment.
- Target Months: Mode B only — how fast you want to be debt-free.
- Min Payment Floor %: Issuer's minimum-payment formula (typically 2% of balance or $25, whichever is greater).
How it Works
Each month: interest = balance × APR/12; balance = balance + interest − payment. Iterating month-by-month gives the exact payoff schedule. For Mode B, the calculator solves P = B × r × (1+r)^n / [(1+r)^n − 1] for the payment where r = APR/12 and n = target months. The minimum-payment path uses the issuer's floor formula and recomputes the floor each month as the balance drops.
The Formula
Mode A: iterate balance_t = balance_{t-1} × (1 + APR/12) − payment
Mode B: Pay = B × r × (1+r)^n / [(1+r)^n − 1]
Min payoff: payment_t = max(0.02 × balance_t, $25)Last reviewed: May 2026

Frequently Asked Questions
Depends on balance, APR, and monthly payment. Example: $5,000 balance at 22% APR. Paying $150/month takes about 47 months and you'll pay $2,000 in interest. Bump that to $250/month and you're done in 24 months with about $1,100 in interest. Minimum payment alone (typically 1-3% of balance) drags out 15+ years and costs more than the original balance in interest. Higher payment dramatically shortens payoff and saves interest. Set a target payoff date and back into the monthly amount needed. The calculator shows months-to-payoff and total interest at any payment level.
Monthly interest = Balance × (APR/12). Example: $4,000 balance at 24% APR. Monthly interest = 4000 × 0.02 = $80. If you pay $150 that month, only $70 goes to principal — slow progress. Each month, interest is recalculated on the new balance. Compound effect makes high-APR debt persistent. Total interest paid over the payoff period depends on payment size and APR. Higher payments reduce balance faster, cutting future interest. The calculator simulates month-by-month amortization showing exactly how much of each payment goes to interest vs principal — the truth about credit card math.
Aggressive payments crush credit card debt fast. Example: $6,000 balance at 22% APR. At $200/month, payoff is 41 months. At $400/month, only 18 months. At $600/month, just 11 months. Goal: pay 3-5x the minimum or set a target payoff in 12-24 months. Use windfalls (tax refund, bonus) to lump-sum reduce balance. Avoid charging new purchases while paying down — that resets progress. Rough rule: pay enough each month so balance drops by at least 5-10% monthly. The calculator computes the exact payment needed for any payoff timeline you choose.
Minimum payments are designed to maximize lender profit. Typical minimum is 1-3% of balance + interest. Example: $5,000 at 22% APR, minimum payment ~$125. Of that, $92 is interest, only $33 reduces principal. Next month, balance barely moved, minimum drops slightly, and the cycle stretches for years. Total payoff: 22+ years and $7,000+ in interest on a $5,000 balance. The minimum keeps you stuck. Even doubling the minimum dramatically shortens payoff. Better strategy: fixed monthly payment, ignoring the declining minimum. The calculator shows the trap clearly with side-by-side scenarios.
APR is the annual interest rate; higher APR means more interest charged on your balance each month. Example: $4,000 balance, $200/month payment. At 18% APR — payoff in 24 months, interest paid ~$800. At 24% APR — payoff in 26 months, interest paid ~$1,200. At 28% APR — payoff in 28 months, interest paid ~$1,500. Even small APR differences add hundreds in interest. Negotiate with the issuer for a lower rate, or transfer to a 0% intro APR card to escape high interest temporarily. The calculator shows payoff timelines and interest paid at different APR levels.
Always pay a fixed amount, not the declining minimum. Example: $5,000 balance, 22% APR. Paying minimum (declining each month) — payoff in 22+ years. Paying fixed $200/month — payoff in 32 months. Paying fixed $300/month — payoff in 20 months. The minimum drops as your balance drops, slowing payoff dramatically. Fixed payment maintains aggressive principal reduction. Pick an amount you can sustain and stick to it until the card is paid off. Auto-pay it to remove temptation. The calculator quantifies the time and money saved by switching from minimum to fixed payment strategy.
Balance transfer to a 0% intro APR card (typically 12-21 months) freezes interest, letting full payments reduce principal. Example: $8,000 at 24% APR — paying $300/month takes 38 months with $3,800 in interest. Transfer to 18-month 0% APR with 3% transfer fee ($240) — same $300 payment clears it in 27 months with only $240 in costs. Saves $3,560. Pitfalls: deferred interest if not fully paid by intro period, transfer fees, and temptation to make new charges on the old card. Use balance transfer strategically with a payoff plan. The calculator handles transfer scenarios.
Understanding the Credit Card Payoff Calculator
Worked Example
Marco has a $5,000 balance at 22% APR. He's deciding between paying the minimum ($100) and paying $250/month.
- Minimum-only: ~342 months (28.5 years), total interest ~$8,400, total paid ~$13,400
- $250/mo: 26 months, total interest ~$1,460, total paid ~$6,460
- $500/mo: 11 months, total interest ~$580, total paid ~$5,580
- Going from minimum to $250/mo saves ~$7,000 in interest and finishes 26 years earlier.
Comparison Table
| Balance | APR | Min-only payoff | $200/mo payoff | $500/mo payoff |
|---|---|---|---|---|
| $2,500 | 20% | 235 mo, $4,200 int | 14 mo, $310 int | 5 mo, $110 int |
| $5,000 | 22% | 342 mo, $8,400 int | 33 mo, $1,460 int | 11 mo, $580 int |
| $10,000 | 24% | 478 mo, $20,000+ int | 91 mo, $7,750 int | 24 mo, $2,500 int |
| $15,000 | 26% | Forever (interest exceeds min) | 173 mo, $19,800 int | 40 mo, $5,200 int |
Min payment = 2% of balance, $25 floor. Numbers approximate; actual issuer formulas vary.

Glossary
- APR
- Annual Percentage Rate — the yearly cost of borrowing on the card. Stated; effective rate is slightly higher due to daily compounding.
- Minimum payment
- The smallest payment that keeps the account current and avoids late fees; typically 1–3% of balance plus interest.
- Grace period
- Time after statement close to pay the full balance with no interest; usually 21–25 days. Lost if you carry any balance.
- Cash advance
- Card-funded withdrawal; usually a higher APR, no grace period, and 3–5% fee. Avoid.
- Universal default
- Banned by CARD Act 2009 — issuers can no longer raise your rate because you missed a payment on an unrelated account.
