The method recommends the following: Use 50% of the money you earn for necessary expenses, such as housing and transportation. Use 20% of your income to gain financial traction. Lastly, 30% of your income can be used on anything you want.
The biggest chunk, 70%, goes towards living expenses while 20% goes towards repaying any debt, or to savings if all your debt is covered. The remaining 10% is your 'fun bucket', money set aside for the things you want after your essentials, debt and savings goals are taken care of.
