In an era of remote work, global travel, and shifting economies, understanding where your money goes in South America is non-negotiable. This article ranks the continent’s most expensive major cities—those with over 500,000 residents—based on the latest Numbeo Cost of Living Index, a tool that tracks essentials like rent, food, and transport against New York City’s benchmark (index 100). For expatriates eyeing a new home, digital nomads chasing affordability, or investors scouting opportunities, these costs matter—prices are climbing, and decisions can’t wait.
South America’s diversity—from Brazil’s megacities to Uruguay’s quiet capital—shapes a complex cost landscape. Economic growth, inflation, and urbanization collide here, making some urban hubs shockingly pricey while others stay accessible.
How We Rank Them
The Numbeo Cost of Living Index pulls real-time, crowd-sourced data on daily expenses—think apartment rents, grocery bills, and bus fares—updated frequently to keep pace with shifting economies. We’re using mid-2023 numbers, the freshest available, to give you a clear, actionable snapshot. Numbeo’s methodology isn’t perfect—data depends on user input—but its breadth and consistency make it a go-to for cross-city comparisons.
This list focuses on cities driving South America’s economic and cultural pulse. We’ve excluded smaller towns to spotlight urban centers where costs hit hardest.
The Top 10 Countdown
1. Montevideo, Uruguay
Cost of Living Index: 40.12
Montevideo tops the list, a compact coastal capital with a steep price tag. Numbeo data shows a one-bedroom apartment in the city center averaging $600 monthly—high for a city of 1.3 million. Groceries sting too: a kilogram of chicken breast costs $8, milk hits $1.20 per liter, and a monthly transport pass runs $40.
Uruguay’s small size drives up import costs—most goods, from food to electronics, come from abroad. The country’s economic policies, like high taxes to fund social programs, add to the burden, yet they also deliver safety and stability rare in the region.
Expatriates flock here for walkable streets and beach access, but the premium is undeniable. A meal out costs $10, utilities for a small apartment add $120 monthly—Montevideo’s charm isn’t cheap.
Despite its size, Montevideo punches above its weight as a cultural hub. For those prioritizing quality of life over savings, it’s a trade-off worth considering.
2. São Paulo, Brazil
Cost of Living Index: 39.23
São Paulo, Brazil’s financial powerhouse, trails Montevideo by a hair. Numbeo lists a central one-bedroom apartment at $500 monthly—not outrageous, but steep for a city of 12 million where sprawl dilutes affordability. A transport pass costs $50, reflecting a metro system battling the city’s notorious gridlock.
As Brazil’s economic engine, São Paulo draws bankers, tech workers, and multinationals, pushing housing demand sky-high. A meal at a mid-range restaurant runs $8, while chicken breast averages $4 per kilogram—moderate, but extras like utilities ($100 monthly) pile on.
The city’s scale amplifies costs—think premium rents in Jardins or inflated Uber fares during rush hour. Yet, its job market and cultural pull keep it a magnet for ambitious newcomers.
Traffic and density mean convenience comes at a price—living near work or nightlife isn’t cheap. For digital nomads, São Paulo offers connectivity and opportunity, but budgets stretch thin fast.
3. Santiago, Chile
Cost of Living Index: 38.45
Santiago blends Andean views with modern costs, ranking third. Numbeo pegs a one-bedroom apartment in the center at $550 monthly—competitive, given Chile’s economic stability. Transport is efficient at $45 monthly, though utilities add $100 and meals average $9.
Chile’s free-market policies have turned Santiago into a hub for foreign firms, driving up real estate in areas like Las Condes. Chicken costs $6 per kilogram, bread $1.50 per loaf—prices reflect a prosperous but pricey capital.
The city’s high livability—safe streets, reliable services—comes with a catch: demand outpaces housing supply. Expatriates and locals compete for space, especially near corporate hubs.
Santiago’s growth as a tech and finance center keeps costs climbing. For those seeking stability in South America, it’s a solid bet—just bring a bigger wallet.
4. Rio de Janeiro, Brazil
Cost of Living Index: 37.12
Rio de Janeiro’s postcard beauty carries a cost. Numbeo shows a central one-bedroom at $450 monthly—high for Brazil, fueled by tourist demand in zones like Copacabana. Transport is a steal at $40 monthly, but food tracks higher: $7 meals, $4 chicken per kilogram.
Tourism inflates prices—short-term rentals squeeze out affordable housing, especially near beaches. Rio’s global fame, from Carnival to Christ the Redeemer, keeps it pricey despite Brazil’s economic ups and downs.
Locals face the same squeeze—utilities hit $90 monthly, and groceries like rice ($1 per kilogram) add up. For expatriates, the lifestyle tax is steep but seductive.
Rio’s energy is unmatched, but living here means paying for the privilege. Budgets bend under the weight of its iconic status.
5. Buenos Aires, Argentina
Cost of Living Index: 35.67
Buenos Aires offers Parisian vibes at a volatile price. Numbeo lists central one-bedroom rents at $400 monthly—reasonable until inflation kicks in. Transport is dirt-cheap at $20 monthly, with meals at $8 and chicken at $5 per kilogram.
Argentina’s economic rollercoaster—currency crashes, 100%+ inflation—distorts costs. For locals, prices soar; for expatriates with dollars, it’s a bargain—until the peso drops again.
The city’s cultural heft—tango, steak, theater—draws global residents, but financial instability clouds planning. Utilities cost $80 monthly, and a coffee runs $2—small expenses that balloon with economic shifts.
Buenos Aires tempts with affordability one day, unpredictability the next. It’s a gamble worth taking if you’re currency-savvy.
6. Belo Horizonte, Brazil
Cost of Living Index: 34.56
Belo Horizonte delivers urban Brazil without the coastal premium. Numbeo shows a one-bedroom apartment at $350 monthly—cheaper than Rio or São Paulo. Transport costs $40 monthly, meals $6, and chicken $3.50 per kilogram—affordable for a city of 2.5 million.
Its inland setting and industrial roots keep prices grounded, while a budding tech scene adds appeal. Residents enjoy a slower pace without sacrificing amenities like parks and nightlife.
Housing demand is rising as startups move in, but it’s still a deal compared to Brazil’s giants. Utilities run $80 monthly—manageable for most budgets.
For those dodging megacity chaos, Belo Horizonte balances cost and opportunity. It’s a sleeper hit gaining traction fast.
7. Porto Alegre, Brazil
Cost of Living Index: 33.89
Porto Alegre, in Brazil’s south, keeps costs low for a major city. Numbeo lists a one-bedroom at $300 monthly—among the cheapest here. Transport is $35 monthly, meals $5, and chicken $3 per kilogram—a steal.
Its European heritage and proximity to Argentina and Uruguay shape a distinct vibe, but costs stay modest. The city’s economy leans on agriculture and trade, avoiding the hype of coastal hubs.
Housing is plentiful, though central areas see slight upticks as remote workers arrive. Utilities cost $70 monthly—practical for a temperate climate.
Porto Alegre offers urban life with breathing room—perfect for budget-conscious expatriates. Its understated appeal is catching on.
8. Brasília, Brazil
Cost of Living Index: 33.45
Brasília, Brazil’s purpose-built capital, surprises with its costs. Numbeo shows a central one-bedroom at $400 monthly—pricier than Porto Alegre, despite its planned design. Transport runs $45 monthly, meals $7, chicken $4 per kilogram.
As the political epicenter, Brasília draws government workers and contractors, inflating central rents. Its layout—wide boulevards, zoned sectors—keeps transport efficient but limits affordable housing options.
Utilities hit $90 monthly, reflecting air-conditioned offices and homes in the tropical heat. Groceries like milk ($1 per liter) align with national norms.
Brasília’s artificial creation means costs reflect its status, not organic growth. For those tied to politics or policy, it’s a necessary expense.
9. Lima, Peru
Cost of Living Index: 32.12
Lima’s coastal sprawl ranks it ninth, a capital on the rise. Numbeo lists a one-bedroom at $450 monthly—high for Peru, driven by upscale districts like Miraflores. Transport is a bargain at $25 monthly, meals $4, chicken $4 per kilogram.
Peru’s economic growth fuels Lima’s costs—tourism and trade pump money into the city. Its desert-edge location keeps utilities ($60 monthly) low, but housing demand climbs.
The gap between rich and poor shows in prices—coastal rents soar, inland stays cheap. Expatriates love the food scene—ceviche for $5—but budgets vary by neighborhood.
Lima’s role as Peru’s gateway keeps it pricey yet accessible. It’s a mixed bag—choose your spot wisely.
10. Salvador, Brazil
Cost of Living Index: 31.23
Salvador rounds out the list with cultural riches on a budget. Numbeo pegs a one-bedroom at $250 monthly—lowest of the top ten. Transport costs $30 monthly, meals $5, chicken $3 per kilogram—affordable for a city of 2.9 million.
Tourism spikes costs in historic Pelourinho, but overall, Salvador lags behind Rio or São Paulo. Its Afro-Brazilian roots and beachfront draw crowds without breaking the bank.
Utilities run $70 monthly, and staples like rice cost $1 per kilogram—everyday life stays cheap. For expatriates, it’s a low-cost entry to Brazil’s vibrancy.
Salvador’s laid-back pace contrasts with its festive spirit—Carnival bumps prices, but year-round living doesn’t. It’s the cheapest of the priciest, a hidden gem.

This table, pulled from Numbeo, breaks down the basics. Rent dominates budgets—transport and food offer some relief, but utilities tip the scales in pricier climates.
What’s Driving the Costs?
Brazil’s six entries reflect its urban heft—São Paulo and Rio thrive on global demand, while Brasília’s political role props up prices. Montevideo’s top spot hinges on Uruguay’s small market—imports jack up everything from apples ($2 per kilogram) to gas ($1.70 per liter). Santiago’s stability and Chile’s trade-friendly policies draw wealth, spiking housing costs.
Urbanization across South America fuels this trend—cities swell as rural migrants and foreign workers pour in. Inflation hits hard in Argentina and Brazil—Buenos Aires’ $400 rent today could jump 20% by next year.
Tourism plays a dual role: Rio and Salvador cash in on visitors, but locals pay more for it. Economic growth lifts Lima and Belo Horizonte, yet currency swings—think Brazil’s real or Argentina’s peso—keep expatriates on edge.
Housing scarcity is the real kicker—central rents rarely drop below $300, even in smaller hubs. Add utilities and transport, and these cities demand serious cash flow.
Cheaper Alternatives Exist
South America isn’t all high rollers—La Paz, Bolivia, scores 28.45 on Numbeo, with $250 rent and $3 meals. Asunción, Paraguay, at 26.78, offers $200 apartments and $4 dinners—low demand and smaller economies keep them cheap.
Quito, Ecuador (index 30.12), boasts $300 rents and $5 meals, blending altitude with affordability. Medellín, Colombia (index 29.45), tempts with $350 apartments and a booming expat scene—costs creep up, but it’s still a deal.
These cities lack the glitz of São Paulo or Santiago, but that’s the point—fewer tourists, less hype, lower prices. For budget travelers or retirees, they’re goldmines waiting to be tapped.
La Paz’s high elevation cuts utility costs—no AC needed—while Asunción’s sleepy pace avoids urban frenzy. Both prove you can live well in South America without breaking the bank.
Why It Matters
Cost of living data isn’t just trivia—it’s a lifeline for expatriates picking a base, nomads chasing Wi-Fi and cheap rent, or investors eyeing real estate. Brazil’s dominance screams opportunity, but Montevideo’s quiet reign warns of hidden costs in smaller markets.
Digital nomads thrive in Lima’s affordability or Salvador’s vibe—São Paulo’s hustle suits the ambitious but drains savings fast. Investors note high rents in Santiago or Rio signal demand—flip that to La Paz or Quito for untapped growth.
Policymakers face a tightrope—rising costs boost tax revenue but squeeze locals, sparking tension in cities like Buenos Aires. For expatriates, currency leverage (dollars in Argentina) can flip the game—knowing these numbers is power.
This data shapes lives—where you move, work, or build matters more as South America’s economies shift. Ignore it, and you’re guessing in the dark.
Final Word
Montevideo, São Paulo, and Santiago headline South America’s costliest cities—urban giants and small capitals alike hit hard. Brazil’s sprawl and Uruguay’s import trap set the pace—don’t sleep on these prices. Lima and Salvador ease the sting if you’re stretched thin.
Pick your spot, but move quick—rents climb, currencies wobble, and opportunities won’t wait. South America’s urban game is on—play it smart.
