In short
- Start from last month's real spending, not from what you wish you spent.
- Agree on a handful of categories and one limit for each.
- Keep everything in one place that everyone can add to.
- Review together once a month, for 15 minutes.

Start from what really happened
Before setting any limit, look at one full month of spending: bank statements, receipts, the cash you remember. Group it roughly. You're not judging anything yet, just finding out where the money goes. Most households are surprised by two or three categories: eating out, small online orders, subscriptions nobody uses.
Pick a few categories everyone understands
Ten to fifteen categories is plenty. If a category needs explaining, merge it. A good test: could your partner or your teenager file a receipt in the right place without asking?
Usually needed
Housing, Groceries, Transport, Bills
Often useful
Eating out, Kids, Health, Holidays
Set limits together
Agree on a monthly limit for the categories that move: groceries, eating out, leisure. Fixed costs like rent don't need a limit; they need to be on the list so they're counted. Write the limits down where everyone can see them.
A household of three with $3,400 coming in each month.
| Category | Last month | Limit |
|---|---|---|
| Housing | $950 | (fixed) |
| Groceries | $412 | $380−$32 |
| Eating out | $160 | $120−$40 |
| Transport | $190 | $190 |
| Bills | $230 | (fixed) |
| Savings | $200 | $300+$100 |
Two changes, $72 less on food, and savings go up by $100.
One place, and everyone adds to it
A budget only one person updates becomes that person's job, and then their worry. Use one shared place where each adult (and teenagers, if you like) can add what they spend the moment they spend it. Seeing who added what makes it a team effort rather than a check on each other.
A 15-minute monthly review
Once a month, sit down together: what went over, what went under, and one thing to change next month. Keep it short and blame-free. The goal is to decide, not to audit.
