The fastest way to pay off debt, whether $6,000 or $60,000, is to start paying the minimum amount on either your highest-interest debt (avalanche method) or your smallest balance debt (snowball method).The debt avalanche method will prevent you from accruing too much in additional interest, while the debt snowball method can help you reduce your number of overall monthly payments.Alternatively, consider a debt consolidation loan or balance transfer credit card to help you pay off debt faster.
