Cost of living in Buenos Aires: how to build your own budget

IDECBA's Q1 2026 rent figures below are monthly benchmarks for standard used flats: 30 m² for one ambiente, 43 m² for two and 70 m² for three. They use peso-denominated Argenprop listings. For each home, ask whether expensas (building charges) are included in the quoted rent and how they are billed.

A Buenos Aires budget is made of a few large bills and many small ones. Rent, building charges, private health cover and school fees decide most of it, and the school decision can change a family's budget far more than the price of a bus journey. Only some of those bills have an official, checkable price: the city's rent averages and the SUBE fares below. For the rest, a written quote for your own household is worth more than any average.

The dated figures matter. In Q1 2026, the city statistics institute put the average asking rent for a used two-room flat, priced on a base unit of 43 m², at ARS 721,267. Expensas (the monthly building charge), health premiums and school fees are set by the building, the plan and the school, so ask for current figures before you commit.

Building your own monthly budget

A budget is easier to trust when each line has a named source. This table shows what sets each line and where to get a figure for your own household. Tax, debt, flights to Britain and savings sit outside it.

Each of these lines is quoted in pesos by the landlord, building, plan or school, and each can change during the year. Sharing a flat could reduce the total; more expensive health cover would raise it.

Rent starts the calculation; expensas finish it

The city's statistics institute recorded Q1 2026 average asking rents for used flats, published in pesos, of ARS 538,595 for a studio (priced on a base unit of 30 m²), ARS 721,267 for two rooms (43 m²) and ARS 1,091,451 for three rooms (70 m²). Among studios, Núñez led at ARS 606,000, followed by Palermo at ARS 588,760 and Belgrano at ARS 582,160. Constitución and Liniers were at the cheaper end, ARS 442,610 and ARS 466,404 respectively.

Those averages are asking rents for used flats, not what a particular landlord will accept. Furnished one-bedrooms aimed at newcomers can sit above them, so compare like with like. furnished apartments on PlataPlace and its Buenos Aires rental search show current asking prices with each listing's source and when it was last seen. Published rents rose between 8.0% and 11.0% on the previous quarter in Q1 2026 and by 32.3% to 34.7% year on year depending on flat size, so the date of a listing changes what its price tells you.

Ask whether expensas are included in the quoted rent and how they are billed before adding them to a housing total. The decree DNU 70/2023 repealed the previous rental law, Ley 27.551, and its text leaves the length of a lease to the parties; its Civil Code changes also release a debtor only by paying in the currency agreed. A dollar-quoted lease may therefore require dollars. The last three expensas statements and recent utility bills for the specific flat give a clearer number than any city average.

Health premiums have an age and plan attached

A prepaga is a private prepaid health plan, closer to Bupa than the NHS. Premiums depend on the plan, the age of each person covered and sometimes the zone, so ask each prepaga for a written quote for every family member, with the copays that apply. Children need their own quoted cover in a household budget. Even at the same age, the plan chosen changes the monthly total considerably, so a single ‘healthcare cost’ can mislead.

School fees change the family equation

Private schools set their own fees, and the monthly fee is only part of the cost. Ask each school for its current fee schedule, including admission, enrolment and other charges, and for the date it applies from. State school removes the tuition line, though uniforms and lunches remain. To compare options, add a school's written fee for each child to your housing, health and daily lines and see which line dominates.

Daily costs after the large bills

The official Red SUBE table for October 2026 puts a city colectivo (bus) journey of 0-3 km at ARS 920.48 with a registered SUBE card, or ARS 1,463.56 without. A subte ride starts at ARS 1,817 and becomes cheaper with monthly frequency, falling to ARS 1,090.20 from the 41st trip; a first-section train ride is ARS 450. Forty subte trips and 20 bus trips in a 20-weekday month come to roughly ARS 82,000 at those fares.

Food at home is best estimated from your own receipts. Coto or Carrefour cover packaged supermarket goods, a verdulería is a greengrocer, and a feria is a street market with seasonal prices. Nappies, pet supplies and toiletries belong outside the food line. Edenor or Edesur electricity can rise with January and February air conditioning, while Metrogas bills climb with winter heating. Previous bills for the flat are the useful comparison.

Comparing a Buenos Aires budget with a British one

A household leaving central London may save more on housing than one leaving a lower-cost British town, while school and health choices can absorb the difference. Three months of UK bank statements give a better starting point than a blanket ‘cheaper than London’ percentage: remove costs that genuinely end, such as council tax or a former commute, and retain UK debt and subscriptions alongside Argentine rent, school and medical quotes. Sterling income brings tax and pension questions as well; the HMRC residence guide and State Pension guide address those separately.

Currency rules and card conversion terms change, so check the BCRA's current rules and your bank's terms for the particular transaction. The useful conversion is the ARS your own card or transfer actually delivers after fees, rather than an assumed ‘blue dollar’ rate. A household budget becomes much more dependable once its rent, building charges and school or health quotes belong to the same month and the same family.
