How this works
Pick municipality A and municipality B (or use a popular pair). The table compares nine official indicators and the right-hand column shows the percentage gap, coloured toward whichever side does better on that row. At the end, a plain-language summary says where buying is cheaper, where earnings are higher and how much IRS each câmara (city council) returns. Nothing leaves your browser.
- 1 Pick the pairTwo search boxes with suggestions, or the one-click popular pairs. The ⇄ button swaps sides.
- 2 Read the gapsEach row shows both values and the percentage gap. Green marks the side that does better on that metric.
- 3 Mind the periodsHomes and rents are 2025/2026; average earnings are 2022, the most recent year that exists per municipality.
- 4 Take the summaryThe final paragraph condenses the comparison. Share the link: the chosen pair stays in the URL.
Frequently asked
Where does the data come from?
Sale prices, new-contract rents, bank appraisals and population come from INE, the national statistics institute (official medians per municipality). The ganho médio (average gross monthly earnings) comes from the Quadros de Pessoal employer census (GEP/MTSSS, via INE), with 2022 the latest published year. The IMI (annual property tax) rate and the IRS give-back come from the official Portal das Finanças lookups. Each metric shows its reference period.
What does "m² per year of work" mean?
It is our affordability indicator: how many square metres of median-priced home a full year of the municipality’s average gross earnings buys (monthly earnings times 12, divided by the median price per m²). It is not a realistic purchase plan, nobody spends 100% of gross pay on housing, but it is the most honest way to compare the balance between local salaries and local prices.
Why do some metrics show "—"?
INE only publishes medians when there were enough transactions or contracts in the period (statistical confidentiality). In small municipalities the median rent, and sometimes the sale price, go unpublished. In those cases the row shows "—" and no difference is calculated.
Are the salaries really from 2022?
Yes, and the row says so. Municipal earnings come from the Quadros de Pessoal employer census, filed once a year and taking about two years to process and publish. 2022 is the most recent year available for every municipality. The other indicators are from 2025 and 2026.
Does this tell me where I should live?
It tells you what the official numbers show, nothing more. It does not measure schools, healthcare, climate, jobs in your field or distance to friends. Use it to put facts into the conversation (what homes cost, what people earn, what IMI you would pay) and decide with everything the numbers cannot see.

DISCLAIMER
A comparison of official medians and rates per municipality: INE sales and rents (2025/2026), average earnings from the Quadros de Pessoal employer census (2022, gross, employees only), 2025 IMI and 2026 IRS from the tax authority. Medians hide large gaps inside each municipality and the m² per year of work indicator is an illustrative ratio, not a purchase plan. Not financial advice.
