When you deposit money from your income source, you simply allocate the appropriate dollar amounts to the budget category accounts, based on your spending plan or budgeting worksheet. It's easy to move money around your various spending categories or budget category accounts whenever you need to. When a bill comes due, you simply transfer money from the budget category account to your checking and then electronically pay the bill. It's easy and extremely fast once you set it up through your banking institution.
You can find several varieties of a budgeting worksheet online that you can print or use as a template in one of your existing programs. Even if you just use it to get ideas, it can be a big help when you sit down to create a money management plan. While not everyone has the same income and expense circumstances, this type of worksheet is a great place to start.
