Consider your expenses. When you design a budget remember to include all the household expenses you incur throughout the year.
Examples of expenses found in a budget include - assests, bank charges, car, donations, clothing, education, gifts,  healthcare, household expenses, insurance, investments, living expenses, mortgage, and taxes.There are two key elements of a budget that people often forget to include.

The first is a contingency expense of 10% of your income, for unforseen expenses that arise throughout the year. These may include additional medical expenses, breakdown of a washing machine, dishwasher, hot water service, or financial education, over and above what you have already budgeted for. This ability to budget for unexpected events will remove the extra stress at the right time.

The second is to budget for saving and investment. Ideally you would allocate at least 20% of your income for savings and investment, but 10% would be a great start.

An important part of the budgeting process is to review your budget figures against actual income and expenses to ensure you are on the right track.

This should be done either monthly or at least every 3 months.
