## How it calculates

The calculator uses an iterative month-by-month simulation rather than a closed-form formula, because minimum payments change every month as the balance decreases. Each month, the following steps occur:

1. Monthly Interest = Current Balance x (APR / 12)
2. Minimum Payment = max(Balance x Minimum Payment Percent, Fixed Floor Amount)
3. Actual Payment = Minimum Payment + Extra Payment (if any)
4. Principal Paid = Actual Payment - Monthly Interest
5. New Balance = Current Balance - Principal Paid

This process repeats until the balance reaches zero. The tool also tracks cumulative interest, total amount paid, and calculates a cost multiplier (Total Paid / Original Balance) to show how many times over you end up paying for your original purchases. The simulation caps at 600 months (50 years) as a safety limit. If the minimum payment does not cover monthly interest, the tool reports that the debt can never be paid off under those terms.

## Who should use this

1. Credit card holders who currently pay only the minimum each month and want to understand the long-term cost of that strategy. 2. People considering how much extra to pay each month and wanting to see the concrete impact on their payoff timeline. 3. Financial educators and counselors who need a visual demonstration of the minimum payment trap for clients or students. 4. Anyone comparing credit card offers who wants to understand how different APRs and minimum payment rules affect the total cost of carrying a balance. 5. Parents teaching teenagers about credit card debt before they get their first card. 6. Debt counselors helping clients build a realistic repayment plan by showing the difference between minimum and accelerated payments.

## Worked examples

Example 1: A cardholder has a $5,000 balance at 22.99% APR with a 2% minimum payment (with a $25 floor).
- Month 1: Interest = $5,000 x (0.2299 / 12) = $95.79. Minimum payment = max($5,000 x 0.02, $25) = $100.00. Principal = $100.00 - $95.79 = $4.21. New balance = $4,995.79.
- After 12 months, the balance has only dropped to approximately $4,948 — just $52 of principal paid in an entire year.
- Total payoff time: approximately 27 years and 6 months. Total interest paid: approximately $11,590. Cost multiplier: 3.32x — you pay more than triple the original balance.

Example 2: Same scenario but adding $100/month extra payment on top of the minimum.
- Month 1: Payment = $100.00 (minimum) + $100.00 (extra) = $200.00. Principal = $200.00 - $95.79 = $104.21. New balance = $4,895.79.
- Total payoff time: approximately 2 years and 9 months. Total interest paid: approximately $1,580. Interest saved vs. minimum only: approximately $10,010.
- The extra $100/month cuts payoff time by about 25 years and saves over $10,000 in interest.

Example 3: A $1,000 balance at 18% APR with 1% minimum payment ($25 floor).
- Minimum payment starts at $25 (the floor). Interest in month 1 = $15.00. Principal = $10.00.
- Total payoff time: approximately 5 years and 2 months. Total interest paid: approximately $548. You pay 1.55x the original balance.

## Limitations

This calculator has several important limitations to keep in mind. First, it assumes no new charges are added to the card during the repayment period; in reality, most people continue using their card, which extends the payoff timeline. Second, the APR is treated as fixed throughout the entire repayment period, but many cards have variable rates that change with the prime rate. Third, it does not account for late payment fees, annual fees, over-limit fees, or penalty APR increases that can result from missed or late payments. Fourth, some credit card companies use more complex minimum payment formulas that include a fixed fee component plus a percentage of the balance plus all interest and fees, which this simplified model does not capture. Fifth, the calculator does not factor in promotional or introductory 0% APR periods. Sixth, tax implications are not considered. Finally, this tool provides educational estimates and should not be treated as a substitute for professional financial advice from a certified financial planner or credit counselor.

## FAQs

**Q:** Why does the balance barely decrease in the first year?


**A:** When you pay only the minimum, most of your payment goes toward interest rather than reducing the principal. For example, on a $5,000 balance at 22.99% APR, about 96% of your first minimum payment is pure interest. This is the core of the minimum payment trap.


**Q:** What is a typical minimum payment percentage?


**A:** Most major credit cards set the minimum at 1% to 3% of the outstanding balance, with a floor of $25 to $35. Some older cards used even lower percentages. Check your card's terms and conditions or your most recent statement for your specific minimum payment formula.


**Q:** How much extra should I pay to make a real difference?


**A:** Even $25 to $50 extra per month can dramatically shorten your payoff timeline and save thousands in interest. Use the extra payment field to experiment with different amounts and find what fits your budget while making meaningful progress.


**Q:** Does this account for compound interest?


**A:** Yes. Credit card interest compounds monthly. Each month's interest is calculated on the current balance (which includes previously accrued interest that was not paid off), so the simulation accurately reflects how credit card interest works in practice.


**Q:** Can I use this for multiple credit cards?


**A:** This tool calculates one card at a time. If you have multiple cards, run the simulation for each one separately. For a strategy to pay off multiple debts, consider using a debt avalanche or debt snowball calculator.


**Q:** Why does my card company want me to pay only the minimum?


**A:** Credit card companies earn revenue from interest charges. The longer you carry a balance, the more interest they collect. Setting low minimums maximizes their interest income while keeping you as a customer in good standing. Understanding this incentive is the first step toward taking control of your debt repayment.
