Snowballing is method of paying off debt. It allows the person to have pyschological wins to continue the grind and hard work of paying debts.
Take all of your debts and line them up but the amounts owed from smallest to largest. Start to pay all of the minimums to avoid fees and put any extra money towards the smallest debts first. After paying off the frist debt take that money and use it on the next smallest. Through time the number of debts should reduce creating a snowball effect.
The best part using this method in my opinion is it being straight forward and creates momentum with keeping you motivated by the number of debts reducing.
Knowing where to start might be the hardest part to payoff debt or having enough motivation to payoff the debt that one might have. Snowballing is method that can give a person a spot to start. Through time you might find options that work better for yourself. This might not be the most effiecent way mathematically, but it can help a person stay focused.
