Budget categories list: organise your household budget in four groups

Four groups instead of a hundred categories

A household budget organizer sorts spending on two levels. The first is four groups that answer "what kind of money is this". The second is categories — up to ten in each group — that answer "what was it for". The group drives your plan; the category shows you where to look for savings.

Two more groups complete the picture: INCOME (salary, bonuses, Child Benefit) and OTHER for one-off items. A transfer between your own accounts is a transfer, not spending, so the organizer leaves it out of the totals.

Monthly budget categories with an example

One person in Ireland, €3,200 net a month. Each category gets a planned amount, and the group totals show the split at a glance:

NEEDS come to €1,870, or 58.4% of income; WANTS and INVEST 13.1% each; DEBT 6.3%. Every group is within its norm, and the €230 left over can go straight to INVEST. Put your own amounts in the free budget template and it adds up the shares for you.

Fixed, variable and irregular expenses

• Fixed (rent, loan repayments, broadband, subscriptions): you enter them once, in the plan for the month. They tell you how much is left for everything else.
• Variable (groceries, fuel, eating out): you sort them every day. This is where savings are found, because each category has its own total and you see which one to trim.
• Irregular (motor tax, the NCT, car and home insurance, the TV licence, Local Property Tax, Christmas, back to school): add up the year, divide by 12 and move that amount to INVEST as a "Goal" every month. €1,800 a year becomes €150 a month, and each bill is already covered when it lands.

How to build your own budget categories list

1. Start from last month's bank statement. Every payment gets a group first; a category appears once a group holds several expenses of the same kind. Three supermarket shops make a "Groceries" category; one bike purchase stays in its group for now.
2. One category, one decision. "Groceries" and "Eating out" are separate because each leads to a different change: a meal plan, or lunch from home. "Bills and broadband" sit together because you review them once a year, at renewal.
3. Name them your way. The list above is a starting point. A home with a baby needs "Baby", a home with a dog needs "Pets". Each category gets its own colour, so you spot it on the chart straight away.
4. Review the list after a month. A category with one expense a month merges with another; a category that keeps growing splits in two. The list grows with your budget.

A household budget rhythm: 2 minutes, 10 minutes, 30 minutes

• Daily, 2 minutes. Yesterday's purchases get a group and a category. Five expenses are five taps. After a week it is a habit; after a month you have a full map of your money.
• Weekly, 10 minutes. Each group's share against its norm, and the amount left over. One decision for the week ahead: which WANTS category to trim, or how much to add to INVEST.
• Monthly, 30 minutes. An amount for each group next month in the budget template, a transfer to your goal on payday, and an overpayment on a debt if something is left — the debt payoff plan shows which one first.

Notebook, spreadsheet or app?

All three work when they have a rhythm. A notebook and a spreadsheet need a Sunday session; an app needs two minutes a day in the free budget app.

Your categories and your goal

The categories list shows where your money is. The goal shows why you organise it: an emergency fund of €5,400, a house deposit, zero debt. In Groworth your goal has an amount, and the way there is split into 100 levels. Every transfer to INVEST and every repayment above the minimum raises your level. The first €300 a month for your goal is covered in How to save money.
