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 Istanbul?
South Korea is the higher earner — average annual wage of $50,947 against $47,253 in Turkey, about 8% more in purchasing-power terms.
Country-level figures — Busan is not South Korea and Istanbul is not Turkey, 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 Istanbul?
Busan is about 8,270 km (5,140 mi) from Istanbul in a straight line — roughly 10 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 Istanbul?
Busan and Istanbul have broadly similar temperatures across the year. Annual sunshine is comparable between the two.
| Month | Busan | Istanbul |
|---|---|---|
| January (high / low) | 8° / 0°C | 9° / 4°C |
| July (high / low) | 28° / 22°C | 29° / 20°C |
Humid subtropical coastal — milder winters than Seoul, humid summers with a wet typhoon-influenced Jul-Sep. The beach city of Korea.
Borderline Mediterranean — warm dry summers, cool wet winters with occasional snow off the Black Sea. The two seas moderate extremes; wind is constant.
Busan's 6.6 score edges Istanbul's 5.5 by meaningful enough margin—the South Korean port city outperforms on livability fundamentals despite Istanbul's global recognition.
Istanbul draws millions of annual tourists and straddles two continents, yet Busan's infrastructure and civic services deliver measurably better day-to-day conditions for residents.
If you're weighing a relocation or investment in a major port city, examine Busan's specific advantages in transportation and housing before assuming Istanbul's cultural prominence translates to practical quality of life.

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 | Istanbul | Winner |
|---|---|---|---|
| Affordability | 7.5 | 6.8 | Busan +0.7 |
| Quality of life | 7.3 | 5.6 | Busan +1.7 |
| Remote-work friendliness | 9.0 | 4.8 | Busan +4.2 |
| Healthcare | 5.6 | 4.8 | Busan +0.8 |
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.
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%)36
- Rent index (weight 40%)27
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Istanbul: ((100 − 36)/100 × 0.6 + (100 − 27)/100 × 0.4) × 10 = 6.8.
Istanbul is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)52
- Healthcare index (weight 35%)68
- Air quality index (weight 25%)45
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Istanbul: (52/100 × 0.4 + 68/100 × 0.35 + 45/100 × 0.25) × 10 = 5.6.
Istanbul 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%)40 Mbps
- Effective income tax (lower = better) (weight 30%)12.6%
- Cost-of-living (lower = better) (weight 25%)36
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Istanbul: (min(40/300, 1) × 0.45 + (1 − 0.126) × 0.3 + (100 − 36)/100 × 0.25) × 10 = 4.8.
Istanbul works for remote work but isn't optimized for it: internet 40 Mbps, income tax 13%, cost index 36.
Healthcare
- Healthcare quality index (weight 70%)68
- Healthcare out-of-pocket / month (lower = better) (weight 30%)2301
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Istanbul: (68/100 × 0.7 + max(0, 1 − 2301/500) × 0.3) × 10 = 4.8.
Istanbul has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~2301 TRY/month. Cross-border insurance closes the gap.
Monthly cost delta: Busan vs Istanbul
Normalized to KRW at 1 TRY = 27.4243 KRW.
| Category | Busan | Istanbul | Change |
|---|---|---|---|
| housing | ₩965,714 | TRY 46,176 | +31% |
| food | ₩640,009 | TRY 14,574 | -38% |
| transport | ₩80,000 | TRY 3,000 | +3% |
| utilities | ₩267,883 | TRY 4,325 | -56% |
| leisure | ₩506,674 | TRY 13,040 | -29% |
| healthcare | ₩60,001 | TRY 2,301 | +5% |
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: Istanbul spends 17.0 percentage points more of its budget on it (55% vs. 38%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Busan ↔ Istanbul
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Busan = 31, Istanbul = 36); currency-converted at 1 TRY = 27.4243 KRW. Tax differences are not modeled.
| Busan gross | Istanbul equivalent |
|---|---|
| ₩40,000 | TRY 1,694 |
| ₩75,000 | TRY 3,176 |
| ₩120,000 | TRY 5,081 |
| Istanbul gross | Busan equivalent |
|---|---|
| TRY 40,000 | ₩944,616 |
| TRY 75,000 | ₩1,771,154 |
| TRY 120,000 | ₩2,833,847 |
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 Istanbul
Busan (Asia/Seoul) and Istanbul (Europe/Istanbul) sit 6 hours apart in standard time. A 9-to-5 in one overlaps the other's for 2 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: Turkish · English: Moderate · Local language: Recommended
Turkish is essential outside multinational firms and tourist zones. English is moderate in Levent/Maslak business districts and among younger professionals; bureaucracy is Turkish-only.

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 (Istanbul).
- FX rate. 1 TRY = 27.4243 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.
