Paying only the minimum balance required by your creditors is designed to keep you in debt for as long as possible. The true power of the debt snowball lies in adding extra monthly payments to the pool.
The Power of the Extra Dollar
Every dollar you add beyond the minimum is applied directly to reducing your principal balance, preventing future monthly interest from accruing. Over time, this compounding effect dramatically accelerates your timeline.
