How This Minimum Payment Calculator Works
Most credit card issuers calculate your minimum payment as a percentage of your outstanding balance — typically 1% to 3%. This calculator shows you exactly what that minimum payment is, and more importantly, what it will cost you long-term if you only ever make that payment.
- Enter your current credit card balance.
- Enter your APR (found on your monthly statement).
- Enter your card’s minimum payment percentage (default is 2%).
- Click “Calculate Minimum Payment” to see your results.
Example Calculation
Here’s what happens when you only make minimum payments on a $5,000 balance:
Scenario: $5,000 balance at 24% APR, 2% minimum payment
This is why minimum payments can be a debt trap. When your minimum payment equals your monthly interest charge, you never reduce the principal. Paying even $50 more per month can make a dramatic difference.

How This Calculator Works
This calculator shows what happens when you make only the minimum required payment on a credit card each month. Minimum payments are typically calculated as a small percentage of your outstanding balance (usually 1–2%) plus any interest and fees, with a floor of around $25–$35. Because the minimum payment decreases as your balance decreases, you end up paying a large proportion of each payment as interest rather than principal — especially in the early months.
The calculator tracks your balance month by month under the minimum payment scenario and compares it against a fixed monthly payment you choose. The difference in payoff time and total interest between the two scenarios illustrates the real cost of minimum-only payments.
When Should You Use This Tool
Use this calculator if you have been making only minimum payments and want to see a concrete picture of where that path leads. The numbers are often surprising — a $3,000 balance at 21% APR paid with minimum payments only can take over four years to clear and cost more than $1,500 in interest. Seeing that figure compared against paying a fixed $100 or $150 per month makes the case for paying more than the minimum far more compelling than a general warning.
This tool is also useful for understanding why your credit card balance seems to barely move despite consistent payments. Minimum payments are deliberately structured to extend repayment — understanding that structure is the first step to working around it.
Example Calculation
Consider a $3,500 balance at 20% APR. The initial minimum payment is approximately $70 (2% of balance). In month one, about $58 of that goes to interest and only $12 reduces the principal. As the balance slowly decreases, so does the minimum payment — meaning progress remains slow for years.
Paying a fixed $120 per month instead clears the same balance in about 38 months and costs roughly $1,050 in interest. The minimum payment path stretches to over 100 months and costs nearly $2,400 in interest — more than double. Paying just $50 more per month cuts the interest cost by more than half.
