It's amazing to watch your debts decrease so fast. I used the Debt Avalanche personally when I was paying off my debts. I can tell you that it works and after you have cleared down a couple of your debts it starts working quickly. You and enter your debts, extra payments, and select which method you want to use. It will calculate the amount to pay on each debt and show you when each debt is paid off. I hope it comes in handy.
I know how scary it can be to be deep in debt and wondering if you can ever escape. I'm here to tell you that you can because I did it myself. I've gone from living pay check to pay check, hundreds of thousands of dollars in debt, to having cash in the bank, stocks, no debt and able to stop working for 6 months for a mini-retirement. If I can do it, then you can too.
