Paying the minimum on $30,000 at 21% APR cost $17,500 over three years, with the balance still near $27,000. Here's the math and a better path.
Three years of minimum payments on $30,000 in credit card debt at 21% APR cost roughly $17,500. The balance dropped by only $3,000 to $4,000. Almost $14,000 of what was paid went to interest.
Minimum payments are typically 1% to 2% of the balance plus interest. On $30,000 at 21%, the first minimum is about $600. Of that, $525 is interest. Only $75 reduces principal. The next month, the balance is $29,925, and the cycle repeats. After 36 months, the remaining balance is still around $26,000 to $27,000.
A fixed $800 monthly payment would clear the debt in about four years and eight months, with total interest around $14,500. That is still high. The interest cost is less than half of what the minimum payment path produces over 20-plus years.
A consolidation loan at 11% to 12% over five years would cost roughly $8,500 in total interest, with monthly payments around $650. That is close to what minimum payments cost now. The debt disappears in five years instead of two decades. The total interest over 20-plus years on a minimum payment path exceeds $40,000.
The Consumer Financial Protection Bureau warns that paying only the minimum on a large balance can stretch repayment beyond 20 years. The lever that matters most is converting from a shrinking minimum to a fixed, aggressive payment. Three years in, the full picture is clear: minimum payments reward the lender, not the borrower.
