How to build a monthly budget in Portugal
8 min readUpdated on
Most budgets fail for one simple reason: they are built on a normal month’s salary, and then life has months that are not normal. This method starts from the other end.

Step 1: find your real monthly income
Do not use what lands in an ordinary month. Add everything that came in over the last twelve months, including holiday and Christmas allowances and bonuses, then divide by twelve.
That figure is lower than July and higher than February, and it is the one to plan with. Allowance months stop being an excuse to spend more and start funding the thin months.
One important warning: money a friend pays back to you is not income. It is the return of an expense that was theirs. Count it as income and your savings rate inflates while the budget lies.
Step 2: separate the meal card from everything else
A meal allowance on a card has two properties that force separate treatment: it only loads on working days actually worked, and it only spends in accepted places.
Add it to the food budget and you will conclude that you spend more on food than you do, while the money leaving your account hides. Use two lines: what the card paid for, and what left the account.
Step 3: turn annual costs into monthly ones
Vehicle tax, car insurance, life insurance, property tax instalments, the car service, tuition. None of these is monthly, and all of them are certain.
Add the annual total and divide by twelve. That amount is a monthly expense, even in months when you pay nothing. Keep it aside in a savings account, and the month the bill lands stops being a problem.
- IUC (vehicle tax): a known annual amount, due in the month of first registration.
- IMI (property tax): paid in May, or May and November, or in three instalments, depending on the amount.
- Insurance: car, health, and the life policy tied to a mortgage.
- Car servicing and the annual inspection.
Step 4: fix the three lines you cannot negotiate
Housing, transport and food consume most of any Portuguese budget. Give them numbers before you look at anything else.
If housing goes above 35% of real monthly income, no cut to your coffee will save the account. Better to know that now than to find out in a year.
Step 5: pay yourself first
Savings are not what is left at the end. What is left at the end tends to be zero. Set a percentage, move it on the day your salary lands, and treat the rest as the money available.
Start with an amount you can sustain, however small. A budget that survives twelve months at 5% beats one that survives two months at 20%.
Step 6: review mid-month, not at the end
A report on the 31st explains what can no longer be changed. What helps is looking around the 12th and comparing spending to the expected pace.
This is the step almost everyone skips, and the only one that changes anything. Navefi makes that comparison on its own and warns you when the month’s pace runs over, with days left to react.
A worked example
Total annual income of 21,000 euros including allowances gives a real monthly income of 1,750 euros. A meal card at 10.20 euros per working day adds around 215 euros a month of food that never leaves the account.
A realistic split: 600 euros housing, 180 transport, 220 food paid from the account, 130 provisioned for annual costs, 90 subscriptions and telecoms, 250 variable spending, and 280 to savings. Nothing is left over, and that is what a budget is: every euro given a destination before it is spent.
Frequently asked questions
How much should housing cost in Portugal?
A prudent reference is to stay below 35% of real monthly income, including rent or mortgage, service charges and related insurance. Above that, the budget loses the slack it needs to absorb surprises.
How do I account for the holiday allowance?
Divide it by twelve and treat it as part of monthly income, rather than as a bonus in the month it arrives. That way the allowance months fund the months without one, instead of generating extra spending.
Does the meal card count as income?
For personal budgeting it counts as a balance dedicated to food, not as available money. It only loads on working days actually worked and only spends in accepted places, so it deserves its own line.
