Cost of Living in Korea for a Foreigner (2026): Seoul vs Busan vs Regional Cities — Rent, Food, Transport, Phone, Insurance, With a Monthly Budget Calculator

This course has walked through the paperwork of arriving; this last part puts a number on living here. Korea is not a cheap country and not an expensive one — eating out, transport and phones are inexpensive by Western standards, rent in Seoul is not, and the deposit system front-loads the cost of a home in a way that surprises everyone. Below is a budget calculator built on 2026 figures with sources, then the line items and how they differ between Seoul, Busan and the regional cities.

Housing: the big variable

	Seoul	Busan	Regional cities
One-room (원룸), monthly rent, ₩10M deposit	≈ ₩820,000 (Q1 2026 average)	≈ ₩550,000–650,000	≈ ₩400,000–550,000
Officetel, central, furnished	≈ ₩1,188,235	≈ ₩800,000–950,000 (Haeundae, Seomyeon)	≈ ₩600,000–750,000
Jeonse (deposit only) for a one-room	≈ ₩217,000,000	≈ ₩120–170M	≈ ₩80–130M
Goshiwon / shared room	₩350,000–600,000	₩300,000–450,000	₩250,000–400,000

The deposit is the cost most budgets forget: ₩5–20 million for a wolse one-room, returned when you leave. The conversion is roughly ₩10 million of deposit for ₩40,000–50,000 of monthly rent, in either direction (Investing Part 6). Add a management fee (관리비) of ₩50,000–150,000 for a one-room or officetel, which typically covers water, cleaning and sometimes internet, and utilities of ₩50,000–120,000 (electricity, gas — heating in January is the expensive month). Employers who provide housing (public-school teachers, many E-9 employers, some E-7 contracts) remove the largest line entirely — value it at ₩700,000+ a month when comparing offers.

Food

Korea's daily food is inexpensive if you eat Korean. A lunch set at a neighbourhood restaurant is ₩9,000–13,000 in 2026; a bowl of noodles or gimbap ₩5,000–8,000; a Korean BBQ dinner for two ₩40,000–70,000; a café americano ₩4,500–5,500. Convenience-store meals run ₩4,000–7,000. Groceries are where Western habits cost money: imported cheese, beef, fruit and wine are pricey, while rice, vegetables, tofu, eggs, chicken and pork are cheap — a single person cooking most meals spends ₩300,000–450,000 a month; someone eating out twice a day, ₩800,000–1,000,000. Delivery apps add ₩2,000–4,000 a delivery.

Transport

₩1,550 a subway ride in Seoul (₩1,600 in Busan), ₩1,500 a bus, with free transfers within 30 minutes; a commuter spends ₩70,000–100,000 a month. Seoul's unlimited 30-day Climate Card (₩62,000) is being replaced in autumn 2026 by a national K-Pass-linked product; the K-Pass refund scheme (20–53% back on 15+ rides a month) is open to registered foreigners with a Korean card. Taxis start at ₩4,800 and a cross-town ride is ₩15,000–25,000; a car adds ₩300,000–500,000 a month in fuel, insurance, parking and tax (Part 7). KTX Seoul–Busan is ₩54,400 each way after the September 2026 fare cut.

Phone, internet, subscriptions

A MVNO plan is ₩10,000–30,000, a carrier plan ₩45,000–90,000 (Part 3); home internet ₩22,000–40,000 unless included in the management fee; streaming and music at global prices. Gyms are ₩50,000–100,000 a month (much less on a 6-month contract); Pilates, golf lessons and climbing gyms are where Seoul discretionary spending goes.

Insurance and tax

For employees these are payroll deductions, not budget lines: about 9.7% of gross for the four insurances plus income tax (Money Basics Part 1); take-home is ≈ 85% of gross at ₩3–5M a month. Non-employees on a long-term visa pay NHIS themselves — ₩158,630 a month minimum for a foreign regional subscriber, half that for students (Money Basics Part 6).

Seoul vs Busan vs the regions

Seoul is 25–35% more expensive than Busan and the regional cities, and almost all of the difference is rent; a Busan one-room at ₩600,000 versus Seoul's ₩820,000, an officetel in Haeundae at ₩850,000 versus Gangnam's ₩1.2M+. Food, phones, insurance and subscriptions are national prices. Transport is a wash (Busan's fares are marginally higher, its distances shorter). What the regions lack is not affordability but the foreigner infrastructure — English-speaking clinics, international schools, the branch that has opened a foreigner's account before — which is why Parts 2–4 of this course matter more in Ulsan than in Itaewon.

The one number to remember

A single foreigner living modestly — a one-room outside the centre, cooking half the time, no car — spends about ₩2.3–2.5 million a month in Seoul including rent, ₩1.9–2.1 million in Busan and ₩1.7–1.9 million in a regional city. On the E-7 salary floor (₩2.6M gross, ≈ ₩2.2M net) that is break-even in Seoul and comfortable elsewhere; on ₩4M gross it leaves ₩800,000–1,200,000 a month to save or remit (Part 5). Korea's cost of living is manageable; what it punishes is arriving without the deposit.

That closes the settling-in course. The travel course — for the friends who visit — starts with the entry rules that changed in 2025 and 2026.
