Did you just get a tax refund, a bonus, a raise or an inheritance? Instead of spreading it out and making small extra payments to all of your debts, opt for the snowball method. Consider paying as much as you can towards the debt with the lowest balance so you can reduce or eliminate it entirely (while keeping the account open). This reduces your credit utilization dramatically and can increase your credit score just as dramatically and quickly. Reducing your credit utilization from 50% of your credit limit down to 30% of your credit limit can result in a 50-point score lift, according to the VantageScore report.
If you already have a good-to-excellent credit score and a low debt-to-income ratio, you may want to consider refinancing your student loans. When you refinance your loans, you take out a new credit-based private student loan and use the money to pay off some or all of your current loans. (The lender will generally send the money directly to your loan servicers.)
