Paying only the minimum on a $4,100 card: 202 months and $5,394 of interest

The article examines the consequences of paying only the minimum on a $4,100 credit card bill with an 18.9% APR. The minimum payment is set at the month's interest plus 1% of the balance, with a $25 minimum. Using the minimum payment only, it takes 202 months to pay off the debt, resulting in $5,394 in total interest, which is more than the original balance.

The payment shrinks each month as the balance decreases, leading to the balance lasting longer than the original debt. Adding a fixed amount to the minimum payment, such as $50 or $100, significantly reduces the total interest paid and the number of months required to pay off the debt. For example, paying a minimum of $50 additional results in 57 months and $1,741 in interest, while paying $100 extra leads to 34 months and $1,066 in interest.

In contrast, making a fixed $200 payment every month without using the minimum formula would only take 25 months and $890 in interest, saving the most time and money. The minimum payment structure is designed to keep consumers paying over an extended period, as the monthly payment decreases as the balance decreases. Different issuers have varying minimum payment formulas, with some using a 2% of the balance or a flat percentage with a different floor.

It is crucial to check the specific formula used by your issuer. Using a calculator, such as the one provided in the article's source, can help determine the exact payoff timeline and interest costs based on your specific situation.
