1. Write down everything and how much you think it will cost. I like to estimate high, just in case something costs more. Also, don't forget to include tax.
2. Break it down into categories. For our personal budget, I have shopping, bills, personal, grocery, etc. For our big project, I included categories, such as payments, allowances, additional cost, future costs.
3. Create a column on your budget that has "difference" of what was spent. This will guide you in future budgets.
4. Balance your checkbook. Okay, this isn't really a budget tip, but so many people don't. I use a software program called "My checkbook." It works great to keep the checkbook balanced. It is a simple program and doesn't cost much $20.
5. Stick to it. Not just by spending within your means, but by recording every purchase you make. You will be much more aware of how much you spend and how much you save!
I suggest if a full household budget it too daunting of a task. Start simple. Budget just one category to begin with. Start with bills. These are about the same each month. Try that for a month and add a shopping budget.
