Minimum vs Fixed Payment
| Metric | Minimum Payment 2% of balance or $25, whichever is higher | Fixed Payment $200.00/mo every month |
|---|---|---|
| Monthly Payment | $100.00 | $200.00 |
| Total Interest | $43,417.39 | $1,749.90 |
| Payoff Time | 80 yr 8 mo | 2 yr 10 mo |
| Total Cost | $48,417.39 | $6,749.90 |
Fixed payment saves $41,667.49 in interest and 934 months (77 yr 10 mo).
Key Insights
At 22.00% on a $5,000.00 balance, minimum payments of $100.00 take 80 yr 8 mo and cost $43,417.39 in interest.
Warning: the minimum-payment interest ($43,417.39) exceeds the original balance — you pay more in interest than you borrowed.
A fixed payment of $200.00 cuts the payoff to 2 yr 10 mo and saves $41,667.49 in interest.

How to Use This Calculator
- 1Enter your current credit card balance.
- 2Set the APR on the card — for credit cards this is typically 18% to 29%.
- 3Set the fixed monthly payment you are considering paying each month.
- 4Review the side-by-side comparison: monthly payment, total interest, payoff time, and total cost for the minimum-payment scenario versus the fixed-payment scenario.
- 5Read the AI Insight panel for a personalized analysis of how many years and dollars the fixed payment saves.
- 6Adjust the fixed payment up and down to find an amount that fits your budget while dramatically shortening the payoff.
Formula
How It's Calculated
MINIMUM PAYMENT SCENARIO (2% of balance or $25, whichever is higher):
Each month:
minimumPayment = max(balance × 0.02, 25)
interest = balance × (APR / 12)
principalPaid = minimumPayment − interest
balance = balance − principalPaid
Repeat until balance ≤ 0 (cap at 600 months to avoid infinite loops).
totalInterestMin = sum of all interest paid
payoffMonthsMin = number of months
monthlyPaymentMin = the first month's minimum (display value)
totalCostMin = originalBalance + totalInterestMin
FIXED PAYMENT SCENARIO (constant payment every month):
Each month:
payment = fixedPayment (constant)
interest = balance × (APR / 12)
principalPaid = min(payment − interest, balance)
balance = balance − principalPaid
Repeat until balance ≤ 0.
totalInterestFixed = sum of all interest paid
payoffMonthsFixed = number of months
monthlyPaymentFixed = fixedPayment
totalCostFixed = originalBalance + totalInterestFixed
WHY FIXED WINS:
The minimum payment shrinks with the balance, so most of it keeps
covering interest. The fixed payment stays constant, so as the
balance drops a growing share goes to principal — dramatically
shortening the payoff and cutting total interest, often by 70%+ on
high-APR revolving debt.Glossary
