Every relocation site publishes a monthly cost table, and this one does too on its city pages. It is worth being straight about what those numbers are: estimates, built from current listings and from what residents report paying. Spain publishes no official cost of living index at city level, so any site presenting these as authoritative is overstating what it knows.
The line that dominates everything
Rent. It is not merely the biggest item, it swings more between cities than everything else combined. The difference between a coastal capital and an inland city can be larger than your entire food budget. Choose the city and you have chosen most of your cost of living.
The lines that catch people out
Electricity, which is not cheap and which moves with the season far more sharply than we were used to. Eating out, which is cheaper than we expected and which we therefore do more of, so the saving quietly disappears. Schooling, if you go international, which can rival rent.
The lines that come in lower
Fresh food from a market. Public transport. Anything involving being outdoors, which in a climate like this is most of what a family does at the weekend.
A budgeting method that holds up
Rent, from real current listings in the specific neighbourhood, not a city average. Then a fixed allowance for utilities and phones. Then food, which we track for a month and then stop tracking. Then a genuine contingency for the first year, because the first year has setup costs that never repeat: deposits, furniture, appointments, translations, and the flights you did not plan.
Budget your first year materially higher than your steady state, and stop hunting for a definitive figure. It does not exist. Anyone publishing one is guessing, with more confidence than the underlying data supports.
