How to make a monthly family budget: a 6-step guide with an example in lei

What is a family budget and why does it help?

A family budget is a simple plan: how much you earn together, how much you spend and how much is left. The goal is not to forbid things, but to avoid the end-of-month question, “where did the money go?”.

It works because it turns vague feelings about spending into numbers you can discuss. When both partners see the same numbers, money conversations get calmer and decisions get easier.

Step 1. How much money comes in each month?

Add up all of the family’s monthly income after tax: salaries, freelance income, rent received, pensions, benefits. If income varies, use the lowest amount of the last 3–6 months so you plan cautiously.

Record irregular income (bonuses, a 13th salary) separately. Keep it out of the monthly budget; use it for savings or big goals.

Step 2. What are your fixed costs?

Fixed costs show up every month in about the same amount. They get paid first.

• Rent or the mortgage payment
• Utilities: electricity, gas, water, heating, waste collection
• Internet, phone, subscriptions (streaming, apps)
• Insurance, kindergarten or school, payments on other loans

A useful trick: look through your bank statement for the last 3 months; forgotten subscriptions show up there.

Step 3. How do you split what is left? The 50/30/20 rule

A simple rule of thumb is 50/30/20: half of income for needs, 30% for wants and 20% for savings and debt. It is not a law; treat it as a starting point.

If a large part of income goes to rent or a loan, needs can exceed 50%. That is not a mistake: cut wants first, not savings. What matters is that the three parts are decided before the month starts.

Step 4. How do you log expenses without forgetting any?

Budgets most often fail because of small, unrecorded spending: a coffee, a delivery, a card tap. A rule that helps: log each expense the same day, in 10 seconds or less.

• Pick one place where everyone logs: a shared app or a notebook within reach.
• Record the amount, the category and, if needed, who paid.
• Photograph large receipts so you do not depend on memory.

In Family Calculator you can type or dictate an expense, send a receipt photo or a Telegram message, and the whole family sees the same data.

Step 5. How much should an emergency fund hold?

An emergency fund covers the unexpected: a repair, an illness, losing an income. A common rule is 3 to 6 months of essential expenses.

Example: if your needs cost 10,000 lei a month, the target is between 30,000 and 60,000 lei. Start small, with the first hundred lei a month, then raise the amount. Keep the fund separate from your everyday account so you do not spend it by mistake.

Step 6. How do you run the 15-minute monthly review?

At the end of each month, sit down together for 15 minutes and answer four questions:

1. How much did we spend against the plan, in each category?
2. Which category went over its limit, and why?
3. What was unexpected and will come back (repairs, holidays)?
4. What do we adjust next month?

Do not look for someone to blame. The aim is to learn what works and fix the plan, not the people.

What are the most common mistakes?

• A budget so strict it leaves no room for wants. It gets abandoned within 2–3 weeks.
• Forgetting yearly costs (insurance, taxes, holidays). Divide them by 12 and set the money aside monthly.
• A budget kept by one person, with the other partner never seeing it.
• Reviewing only when a problem appears instead of regularly.
• Mixing savings money with everyday money.
