Explanation: The formula calculates how much interest you'll pay each month on your credit card balance when used as a loan.
Details: Knowing your monthly interest cost helps you understand the true cost of borrowing via credit card, plan repayment strategies, and compare with other loan options.
Tips: Enter your current credit card balance (principal) and the card's APR. The calculator will show your estimated monthly interest cost.
Q1: Is this the same as minimum payment?
A: No, this is just the interest portion. Your minimum payment would include this interest plus a percentage of principal.
Q2: Does this account for compound interest?
A: This shows simple monthly interest. Actual costs may be higher if interest compounds daily.
Q3: What if I make payments during the month?
A: This calculator assumes constant balance. Making payments would reduce principal and subsequent interest.
Q4: Are there other fees with credit card loans?
A: Cash advances often have additional fees (3-5% of amount) and higher APRs than purchases.
Q5: How can I reduce these interest costs?
A: Pay more than minimum, transfer to lower-rate cards, or consider personal loans with fixed terms.
