How to Calculate Your Credit Card Minimum Payment
Credit card minimum payments are usually calculated from your current balance, interest, fees, and a minimum dollar floor. The exact formula varies by issuer and card agreement. Two representative approaches are shown below so you can understand how an estimated payment is produced.
Your issuer's actual formula may be different. Check the minimum payment due on your latest statement and review your card agreement for the exact percentage, interest treatment, fees, and payment floor.
Method 1
1% of Balance + Monthly Interest
Example balance: $5,000, APR: 24%
1. Calculate monthly interest
$5,000 × 24% ÷ 12 = $100
2. Calculate 1% of the balance
$5,000 × 1% = $50
3. Add them together
$100 + $50 = $150
Payment floor check
If the issuer applies a $35 minimum floor, the payment remains $150 because the calculated amount is already higher than the floor.
What this means
With this type of formula, the minimum payment can change as both your balance and monthly interest change. As the balance falls, the required payment may gradually decrease.
Method 2
2% of Current Balance
Example balance: $5,000, APR: 24%
1. Take the current balance
$5,000
2. Apply the percentage
$5,000 × 2% = $100
3. Check the payment floor
$35 minimum floor
Payment floor check
The percentage-based result is already above the $35 floor, so the estimated minimum remains $100.
What this means
With a percentage-of-balance formula, the minimum payment usually decreases as the outstanding balance gets smaller. This can significantly extend the payoff period if no additional amount is paid.
Example: How Minimum Payments Affect a $5,000 Credit Card Balance
Using the same calculation engine as the calculator above, this example shows how a declining minimum-payment formula can affect payoff time, total interest, and the amount you repay.
Illustrative example only. This scenario uses a simplified representative minimum-payment formula and monthly interest estimate. Actual issuer calculations can differ because of daily interest, fees, statement timing, past-due amounts, promotional rates, and card-specific rules.
Example assumptions
- Starting balance

- Minimum payment formula
- 1% of current balance + estimated monthly interest
- Minimum payment floor
- $35
- Extra monthly payment

How the payment changes
Month 1
- Balance
- $5,000
- Interest
- $100
- 1% of balance
- $50
- Minimum payment
- $150
Month 12
- Balance
- $4,477
- Interest
- $90
- 1% of balance
- $45
- Minimum payment
- $134
Later
Once the percentage-based calculation falls below the payment floor, the minimum payment remains at $35 until the final payment.
Why the payoff takes so long? Because the minimum payment declines as the balance falls, less money is applied each month than with a fixed-payment plan. That can extend the payoff period and increase total interest.
What If You Paid $50 Extra Each Month?
Comparison of minimum payments only and minimum payments plus $50| Scenario | Payoff time | Total interest | Total repaid |
|---|
| Minimum only | 16 years 9 months | $8,442 | $13,442 |
|---|
| Minimum + $50 | 5 years 5 months | $3,068 | $8,068 |
|---|
Potential Impact of the Extra $50
Time saved
11 years 4 months
Interest saved
$5,374
Earlier debt-free date
December 2031
In this example, adding $50 per month could shorten the payoff period by 11 years 4 months and reduce estimated interest by $5,374.
