Busan vs Mumbai: cost, size & quality of life compared
Trying to decide between Busan and Mumbai? Here's the honest bottom line first — then the full, sourced breakdown on cost of living, salary, safety and quality of life.
Busan comes out ahead overall — decisively.
But the "winner" depends on what you care about. Here's who takes each dimension:
Composite scores
Overall: Busan wins by 1.7 points
Population & size
Is Busan bigger than Mumbai?
Mumbai is the bigger city: about 13M people versus Busan's 3.4M — roughly 3.7× larger.
City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
National income
Is Busan richer than Mumbai?
The two sit on different measures, so we are not ranking them: South Korea is reported as average annual wage ($50,947), India as income per capita (GNI, PPP) ($11,000). A full-time wage and a whole-population income per head are not the same quantity.
Country-level figures — Busan is not South Korea and Mumbai is not India, and both cities typically pay above their national average. Gross, before tax: see take-home pay by country for what lands in the account.
Distance
How far is Busan from Mumbai?
Busan is about 5,760 km (3,580 mi) from Mumbai in a straight line — roughly 7 h 30 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Busan warmer than Mumbai?
Mumbai is the warmer city: January highs average 31°C vs 8°C, and July 30°C vs 28°C. Mumbai gets noticeably more sun — about 380 more sunshine hours per year.
| Month | Busan | Mumbai |
|---|---|---|
| January (high / low) | 8° / 0°C | 31° / 17°C |
| July (high / low) | 28° / 22°C | 30° / 25°C |
Humid subtropical coastal — milder winters than Seoul, humid summers with a wet typhoon-influenced Jul-Sep. The beach city of Korea.
Tropical with an extreme monsoon — nearly all of the ~2,200mm falls June-September, flooding streets on peak days. Dry sunny winters are excellent.
Busan's 6.6 score reflects stronger infrastructure and livability fundamentals than Mumbai's 5.5, driven by superior transit connectivity and lower pollution exposure.
The 1.1-point gap between these 14-million-plus metros is significant—Busan's organized port district and predictable services contrast sharply with Mumbai's chronic congestion.
If transit reliability and air quality matter most to your decision, Busan's proven systems warrant deeper investigation; if you prioritize economic dynamism and lower costs, test Mumbai's neighborhoods directly first.
Data signals
What separates Busan and Mumbai
How decisive
Busan comes out ahead by 1.7 composite points — a decisive win.
Biggest difference
The widest gap is remote-work friendliness, where Busan leads by 3.5 points.
Where they match
They're most evenly matched on affordability — within 0.6 points of each other.
Overall cost gap
Total monthly costs in Mumbai run about 45% lower than in Busan.
Where budgets split most
Transport is the line item that diverges most: roughly 91% cheaper in Mumbai than Busan.
Size difference
Mumbai is the larger metro — about 3.7× the population of the other, which shapes commute times, housing supply and how "big-city" daily life feels.
Home internet
Busan has the faster typical broadband (300 vs 60 Mbps median) — worth weighing if you work remotely or move large files.
Safety
Busan scores higher on safety (78 vs 54 / 100) — a common deciding factor for families.
Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Busan | Mumbai | Winner |
|---|---|---|---|
| Affordability | 7.5 | 8.1 | Mumbai +0.6 |
| Quality of life | 7.3 | 5.0 | Busan +2.3 |
| Remote-work friendliness | 9.0 | 5.5 | Busan +3.5 |
| Healthcare | 5.6 | 4.2 | Busan +1.4 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)31
- Rent index (weight 40%)16
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Busan: ((100 − 31)/100 × 0.6 + (100 − 16)/100 × 0.4) × 10 = 7.5.
Busan sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)78
- Healthcare index (weight 35%)80
- Air quality index (weight 25%)55
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Busan: (78/100 × 0.4 + 80/100 × 0.35 + 55/100 × 0.25) × 10 = 7.3.
Busan scores good on safety, excellent on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)300 Mbps
- Effective income tax (lower = better) (weight 30%)6.8%
- Cost-of-living (lower = better) (weight 25%)31
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Busan: (min(300/300, 1) × 0.45 + (1 − 0.0684) × 0.3 + (100 − 31)/100 × 0.25) × 10 = 9.
Busan combines fast internet (300 Mbps median), a 7% effective income tax and cost index 31 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)80
- Healthcare out-of-pocket / month (lower = better) (weight 30%)60001
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Busan: (80/100 × 0.7 + max(0, 1 − 60001/500) × 0.3) × 10 = 5.6.
Busan has trade-offs in healthcare: quality is excellent, typical out-of-pocket cost is ~60001 KRW/month. Cross-border insurance closes the gap.

- Cost-of-living index (weight 60%)20
- Rent index (weight 40%)17
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Mumbai: ((100 − 20)/100 × 0.6 + (100 − 17)/100 × 0.4) × 10 = 8.1.
Mumbai sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)54
- Healthcare index (weight 35%)60
- Air quality index (weight 25%)30
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Mumbai: (54/100 × 0.4 + 60/100 × 0.35 + 30/100 × 0.25) × 10 = 5.
Mumbai has a mixed quality profile. Safety: fair; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)60 Mbps
- Effective income tax (lower = better) (weight 30%)13.0%
- Cost-of-living (lower = better) (weight 25%)20
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Mumbai: (min(60/300, 1) × 0.45 + (1 − 0.13) × 0.3 + (100 − 20)/100 × 0.25) × 10 = 5.5.
Mumbai works for remote work but isn't optimized for it: internet 60 Mbps, income tax 13%, cost index 20.
Healthcare
- Healthcare quality index (weight 70%)60
- Healthcare out-of-pocket / month (lower = better) (weight 30%)3082
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Mumbai: (60/100 × 0.7 + max(0, 1 − 3082/500) × 0.3) × 10 = 4.2.
Mumbai has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~3082 INR/month. Cross-border insurance closes the gap.
Monthly cost delta: Busan vs Mumbai
Normalized to KRW at 1 INR = 13.9963 KRW.
| Category | Busan | Mumbai | Change |
|---|---|---|---|
| housing | ₩965,714 | ₹61,720 | -11% |
| food | ₩640,009 | ₹15,410 | -66% |
| transport | ₩80,000 | ₹525 | -91% |
| utilities | ₩267,883 | ₹5,749 | -70% |
| leisure | ₩506,674 | ₹12,328 | -66% |
| healthcare | ₩60,001 | ₹3,082 | -28% |
Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is housing: Mumbai spends 24.1 percentage points more of its budget on it (62% vs. 38%). If you're sensitive to that category, weight the per-axis scores accordingly.
Buying property
Apartment prices: Busan vs Mumbai
Approximate asking prices in EUR per square meter (as of 2025-01), central vs mid-distance neighborhoods.
Buying in central Mumbai runs about 46% cheaper per square meter (€5,200/m² vs €9,700/m²).
Midpoints of public listing ranges — a scoping number for rent-vs-buy thinking, not a valuation. Renting comparisons live in the cost table above.
Getting around
Public transport: Busan vs Mumbai
Monthly pass and casual-ride pricing in EUR (as of 2025-01) plus the modes each network runs.
Four metro lines + the BGL light line under a T-money-compatible fare system; the K-Pass rebate scheme effectively discounts regular commuting.
Single ride: €1.05 · Modes: Metro, Light rail, Bus
BEST unlimited bus monthly at INR 1,800; suburban-rail season tickets are separate and famously cheap (a few hundred rupees per distance slab). The local trains carry the city — crowding defines the experience.
Single ride: €0.11 · Modes: Commuter rail, Bus, Metro, Monorail
Salary equivalence: Busan ↔ Mumbai
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Busan = 31, Mumbai = 20); currency-converted at 1 INR = 13.9963 KRW. Tax differences are not modeled.
| Busan gross | Mumbai equivalent |
|---|---|
| ₩40,000 | ₹1,844 |
| ₩75,000 | ₹3,457 |
| ₩120,000 | ₹5,531 |
| Mumbai gross | Busan equivalent |
|---|---|
| ₹40,000 | ₩867,771 |
| ₹75,000 | ₩1,627,070 |
| ₹120,000 | ₩2,603,312 |
Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

Remote work logistics
Time zones and language: Busan vs Mumbai
Busan (Asia/Seoul) and Mumbai (Asia/Kolkata) sit 3.5 hours apart in standard time. A 9-to-5 in one overlaps the other's for 4.5 hours a day.
Official: Korean · English: Limited · Local language: Recommended
Less English than Seoul — Korean is needed for most daily interactions outside the university district and tourist beaches. Admin and services assume Korean.
Official: Marathi, Hindi · English: High · Local language: Helpful
English is the language of corporate India and fully workable in Mumbai business and services; Hindi/Marathi carry street life. No script barrier for signage in the business districts.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Busan) and 2026-06-10 (Mumbai).
- FX rate. 1 INR = 13.9963 KRW, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence
Data as of . Last reviewed .
Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Busan is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
