The salary to live in Belgium depends first on where you rent and how many people one payslip must support. A useful starting point is an ordinary month’s take-home pay. An annual offer can sound generous while leaving little cash in the month you pay a deposit.
What does €4,000 gross buy you?
Take a single salaried office worker with no children. A Belgian payroll illustration for September–October 2026 puts €4,000 gross a month at roughly €2,615 net. Your family situation, benefits and payroll deductions can change that result. Ask the employer for a simulation using your details, including a normal month and any separate holiday or year-end payment. Worked gross-to-net example · SD Worx payroll calculator.
Three monthly budgets for newcomers
These are Together’s November 2026 planning examples, in euros per household. Each assumes a renter who uses public transport and cooks most meals at home. The family has two adults and one school-age child in local schooling. Replace each allowance with your own quote. Full-time childcare, private school fees, a car and debt repayments would come on top.
| Monthly allowance | Single, Brussels | Couple, Antwerp | Family, Liège |
|---|---|---|---|
| Rent | 1,150 | 1,100 | 1,050 |
| Energy, water, building charges and telecoms | 220 | 260 | 300 |
| Food and household shopping | 320 | 530 | 680 |
| Transport | 60 | 120 | 150 |
| Health, insurance and personal costs | 130 | 210 | 280 |
| Leisure, clothing and irregular expenses | 200 | 300 | 380 |
| Monthly reserve | 250 | 350 | 400 |
| Net household income to fund this example | 2,330 | 2,870 | 3,240 |
In the Brussels example, the €4,000 gross offer leaves about €285 after the listed costs and reserve. If the flat costs €1,400 instead of €1,150, that margin falls to €35. For a couple, compare the combined net payslips with the household total. Two people on different salaries cannot reliably estimate their combined take-home pay by applying one percentage to the total gross.
How the three rental markets compare
For Brussels, Eurostat’s 2025 market-rent exercise lists €1,150 for a one-bedroom flat. The more recent Federia barometer puts the average Brussels apartment across sizes at €1,366 for the first half of 2026. In Antwerp, CIB’s apartment average was €1,009 over the same half-year.

For Liège city, a summary of 2025 federal figures gives a median apartment rent of €675. That figure covers a different sample and year. A family looking for an extra bedroom should price actual listings near the school or station. The €1,050 in our budget is an allowance for that search. Liège city rental figures and methodology.
Before you accept an offer
Get three figures in writing: expected net pay in an ordinary month, guaranteed annual cash, and the benefits that replace bills you would otherwise pay yourself. Then price the commute and a flat you would genuinely rent. For the practicalities that follow, see Together’s relocation guide.
