Key figures — as of 2026-10-16: Inflation hit 3.6% in September 2026, the highest in three years, per INE — up from 3.3% in August — driven by energy (+15.3%) and unprocessed food (+3.7%); DECO Proteste's grocery basket peaked at a record €261.89 in early May 2026 and is climbing again after easing to €254.73 in September; a Deco/Universidade Católica/Mercadona survey of 2,000 adults found 53% report less purchasing power than a year ago, and 77% say they're "very worried" about the cost of living.
The number that matters
Portugal's annual inflation rate accelerated to 3.6% in September, confirming the preliminary estimate and a rise of 0.3 percentage points compared with August, according to the Instituto Nacional de Estatística (INE). That's the highest level since August 2023, and for anyone budgeting a move to Portugal, the detail that matters most is where the pressure is coming from: energy prices rose 15.3% year-on-year (up from 12.2% in August), while unprocessed food climbed 3.7% (from 3.4% the previous month).
Groceries are the part of the budget newcomers feel immediately — before rent contracts, before tax filings, before anything else. DECO Proteste's weekly-tracked cabaz alimentar, a basket of 63 everyday staples, hit €261.89 in the first week of May 2026, the highest since monitoring began. It eased slightly over the summer to €254.73 on 2 September 2026, but has started rising again heading into autumn — consistent with INE's own food-inflation readings ticking back up in September.
Most people say they're worse off
The grocery numbers land alongside a fresh sentiment survey that confirms what the price tags suggest. A study by Deco, Universidade Católica and Mercadona, based on a survey of 2,000 adults living across Portugal's 18 mainland districts, found that 53% of consumers report a decrease in their purchasing power over the last 12 months. Breaking that down: 38% say they felt a slight decrease and 15% a significant one, while only 4% report a significant increase and 9% a slight one.
The anxiety is widespread — 77% of respondents say they're very worried about the cost of living — and it's changing behaviour at the till. Nearly seven in ten (68%) say they need to control spending more, and 78% have already changed, at least partly, how they shop. Around 75% now compare prices, hunt promotions and regularly buy private-label products, and 83% use loyalty cards or apps.
GrowIN's take: what this means in euros
Here's the calculation that matters for anyone planning a monthly budget from abroad. DECO's basket has risen from around €188 at the start of tracking in January 2022 to its May 2026 peak — a gap of €71.13, or a 37.9% increase over the period. Spread that extra €71 a month over a year, and a household relying on a 2022-era grocery estimate is underbudgeting by roughly €853 annually — before even accounting for rent, utilities or healthcare top-ups. At October's basket price of around €256, a single adult on the €920 national minimum wage would need to spend close to 28% of that wage on food essentials alone, a figure worth building into any relocation budget rather than discovering it after arrival.
"For newcomers, Portugal's grocery basket is no longer the budgeting shortcut it used to be," says GrowIN Portugal Editorial.
Why this matters to foreigners moving in
Cost-of-living comparisons that circulate online — the ones built on older averages — tend to undersell how fast essentials have moved in the last four years. Anyone using Portugal's lower-cost reputation as a line item in a visa or relocation plan, whether on a D7, D8 digital nomad visa, or a Golden Visa fund route, should treat grocery and energy costs as a moving target rather than a fixed number. Our relocation planning guide breaks down how to build a realistic first-year budget that accounts for this kind of drift, rather than relying on year-old estimates.
What to watch next
INE publishes its October inflation reading in mid-November, and DECO updates its basket weekly — both are worth checking before finalising any relocation budget. The Bank of Portugal's own outlook strikes a cautiously optimistic note, suggesting household income, net of price rises, should keep growing through 2028, albeit more slowly than in 2025, which would support purchasing power for most households — but that's a multi-year forecast, not relief for this month's shopping list. For now, the trend is unmistakable: prices are still climbing, and most residents say they're feeling it.
