Understanding Your $20,000 Debt at 18%
A $20,000 debt at 18% interest costs $300 per month in interest alone — $3,600 annually. At this mid-range rate, slow payoff becomes expensive. Payments that are 10–15% of the balance or more will clear the debt in a reasonable timeframe. If possible, refinancing to a lower rate can save thousands in total interest.

How to Pay Off Debt Faster
- Increase monthly payments by any amount — even small increases reduce total interest dramatically.
- Refinance to a lower interest rate if your credit score has improved since you took on the debt.
- Use the debt avalanche method — pay minimums on all debts and put extra toward the highest-rate debt first.
- Avoid taking on new debt while paying down existing balances.
