The Range: Shoestring to Mid-Range

A realistic 30-day South America travel budget varies from approximately $1,200 (extreme shoestring — dormitory hostels, local food only, overnight buses everywhere, no major paid attractions) to $4,500 (comfortable mid-range — private rooms, good local restaurants, internal flights, and key attractions). The majority of backpackers and independent travellers land somewhere between $1,800 and $3,000 for 30 days, depending heavily on which countries they visit and whether their itinerary includes the major premium experiences (Machu Picchu, Galápagos, Patagonia).

South America Daily Budget by Country

Bolivia ($30–50/day): The cheapest country on the continent. Dormitory beds from $8, set lunches (almuerzo) $2–4, local transport minimal. The Uyuni salt flat tour ($120 for 3 days all-inclusive) is the main budget spike.
Peru ($40–65/day): Affordable outside Machu Picchu. Cusco hostel dorms $12–18, excellent set lunches $3–6. Budget spikes: Machu Picchu entry ($52), Inca Trail permit ($225 in the permit fee alone).
Colombia ($40–65/day): Excellent value. Medellín and Bogotá have good hostel infrastructure ($12–20 dorm). Set lunch (bandeja paisa or almuerzo ejecutivo) $4–7. Internal flights Bogotá–Cartagena from $30–60 booked ahead.
Ecuador ($45–70/day): Moderate. Quito and Cuenca are affordable ($15–25 dorm, $5–8 meals). The Galápagos is a separate budget entirely — $150–300/day land-based, $250–600/day cruise.
Chile ($65–100/day): The most expensive country. Santiago private rooms $60+, Patagonia adds significant costs. Patagonia W Trek accommodation, transport, and park entry: $300–600 total for 5 days.
Argentina ($50–80/day with USD): Complex exchange rate makes Argentina effectively cheap for those with USD cash. Use legal parallel exchange and the daily cost drops significantly.
Brazil ($55–85/day): Mid-range. Rio accommodation is expensive in Ipanema/Copacabana ($80+ for private rooms). São Paulo and inland cities more affordable.

The Big Ticket Items: Budget These Separately

Several South America experiences require specific budget allocation separate from your daily costs. Machu Picchu entry: $52. Inca Trail (4 days, all-inclusive): $600–900. Galápagos Islands (7-day budget cruise): $1,750–2,100 all-inclusive. Torres del Paine W Trek (5 days, refugios): $300–500 total. Amazon lodge (4 nights, Peru): $400–700 all-inclusive. Brazilian e-visa (US/Canadian/Australian): $80. These items are not incidentals — they are the primary costs of the key South America experiences and should be budgeted as line items before calculating a daily spend.

30-Day Budget Breakdown: A Realistic Example

Route: Lima → Cusco → Machu Picchu → Puno → La Paz → Uyuni → Salta → Buenos Aires. Accommodation (mix of dorms and private rooms, 30 nights): $480. Food (mix of set lunches, market meals, occasional restaurants): $360. Transport (buses, 2 internal flights): $420. Machu Picchu entry and train: $180. Uyuni 3-day tour: $120. Argentine Malbec and steak dinners (non-negotiable budget line): $90. Miscellaneous (tips, water, laundry, museum entry): $150. Total: approximately $1,800 — a genuine 30-day itinerary covering multiple countries at a comfortable backpacker level without the premium add-ons.
