My husband and I have been doing the Dave Ramsey Debt Snowball system/budget for the last 2 years and we have paid off 2 cars, 3 credit cards, and are still going strong. I would recommend it to EVERYONE!
Easy charts and info to help you know how much you should budget for groceries, gas, home repairs, etc. for each month, PLUS super easy way to track it all. This has - literally - changed our financial lives, and it's so easy it's almost embarrassing.
