How to make a family budget: method, categories and tools

1. List the household’s take-home income

Salaries, benefits, pensions, side income: note what actually lands in your accounts each month. If part of it varies, use a cautious estimate rather than your best month.

2. List fixed costs

These are expenses that come back every month for a roughly known amount: rent or mortgage, utilities, insurance, internet and phone, transport, school meals, childcare, subscriptions. Go through your last three statements so nothing slips through.

3. Estimate variable spending by category

Groceries, gas, outings, clothes, gifts: look at what you spent in previous months and set a realistic amount for each category. A budget that is too tight gets dropped after three weeks.

4. Plan savings and yearly expenses

Set money aside at the start of the month, even a little, rather than “whatever is left”. Also think of costs that come once a year (back to school, property tax, car insurance, vacations): divide them by 12 and put that aside every month.

5. Review and adjust every month

Compare what was planned with what was spent. If a category goes over every month, it is not a failure: the budget needs adjusting.

Well-chosen categories, neither too many nor too vague, are the key to a readable budget. Here is a starting point that covers most families:

Add subcategories only where they help, for example “school meals” and “activities” under Kids if it is a big item.

• A budget every adult in the household can see. If only one person tracks spending, the budget quickly becomes “their” problem.
• Alerts before you overspend, not after. Knowing you have used 80% of the grocery budget by the 20th changes decisions.
• Automated fixed costs. The less there is to log by hand, the longer tracking lasts.
• A short monthly check-in: ten minutes to look at categories and adjust next month.
• Involve the kids depending on their age: a budget for outings or pocket money teaches them to make trade-offs.

• Notebook or spreadsheet: free and flexible, but hard to share and keep up to date with several people.
• Banking and aggregator apps: they categorize transactions automatically, but need access to your accounts and show the whole statement, not just family spending.
• Shared budget apps: each member adds expenses, everyone sees this month’s budget.

SAVY is a shared budget app built for the household: a monthly budget with alerts at 80, 90 and 100%, categories and subcategories, recurring expenses for rent and subscriptions, and stats by category. The free plan includes one overall monthly budget, two recurring expenses and up to 4 members; SAVY Plus adds category budgets, unlimited recurring expenses and unlimited members. No bank connection needed.

In many families, expenses are paid from several accounts. Then you also need to know who paid what, so the split stays fair. If your incomes differ, splitting by income is a good starting point. For blended families, log costs specific to one child separately if they are not shared.
