Formula Used
The Southwest Credit Card Calculator uses the following formulas to calculate your interest charges and payments:
Monthly Payment Calculation
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Current balance
- r = Monthly interest rate (APR/12/100)
- n = Term in months
Total Interest Calculation
Total Interest = (Monthly Payment × n) - P
Total Amount Paid
Total Amount Paid = Monthly Payment × n
These formulas help you understand the true cost of your credit card usage and make more informed financial decisions.
Worked Example
Let's look at an example to see how the Southwest Credit Card Calculator works. Suppose you have a credit card balance of $2,000 with an APR of 18% and you want to pay it off in 12 months.
Example Calculation
Current Balance: $2,000
APR: 18%
Term: 12 months
Monthly Interest Rate: 18%/12 = 1.5% or 0.015
Monthly Payment: $2,000 × (0.015(1 + 0.015)^12) / ((1 + 0.015)^12 - 1) ≈ $176.12
Total Interest: ($176.12 × 12) - $2,000 ≈ $133.44
Total Amount Paid: $176.12 × 12 ≈ $2,113.44
In this example, paying off a $2,000 balance at 18% APR over 12 months would cost you an additional $133.44 in interest, bringing your total payment to $2,113.44.

What if I want to pay off my balance faster?
If you want to pay off your balance faster, you can either make larger payments or pay off the balance in full each month. However, keep in mind that paying off your balance in full each month may not always be the best financial decision.
Is it better to pay off my credit card balance in full each month?
Paying off your credit card balance in full each month can help you avoid interest charges and build your credit history. However, it may not always be the best financial decision, as it may limit your ability to use your credit card for other purposes.
