To start setting up a family budget, take an honest inventory of your household's income and expenses. Begin by categorizing regular expenses such as housing, utilities, food, transportation, insurance, minimum debt payments, and other necessary expenses. Then, list all your one-time expenses like annual bills, gifts, or emergencies. With this data, you can determine if your spending habits align with your goals, and identify areas for improvement.
Consider the needs over wants, to allocate 50-30-20: 50% for essential needs, 30% for discretionary spending, and 20% for saving and debt repayment.
Track your expenses manually or use a budgeting app like Mint or Personal Capital to make tracking easier. Make adjustments regularly and review it every few months. Consider automating bills payments to minimize late fees.
Consider implementing the 'Envelope System', where each envelope represents an expense category. Allocate specific amounts, place cash into corresponding envelopes and stick to it to ensure you stay within your means.
Remember that budgeting is not a one-time task but an ongoing process, requires discipline, commitment and continuous learning and improvement.
