Distance
How far is Miami from Seoul?
Miami is about 12,420 km (7,720 mi) from Seoul in a straight line — roughly 15 h 20 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.

Miami is the warmer city: January highs average 25°C vs 2°C, and July 32°C vs 29°C. Miami gets noticeably more sun — about 1,085 more sunshine hours per year.
| Month | Miami | Seoul |
|---|---|---|
| January (high / low) | 25° / 17°C | 2° / -6°C |
| July (high / low) | 32° / 25°C | 29° / 22°C |
Tropical. Hot humid year-round; summer thunderstorms daily, hurricane season June-November. Mild winters are the trade-off.
Continental with monsoonal summers. Cold dry winters, hot humid wet summers, distinct rainy season in July. Yellow-dust events in spring.
Seoul's 6.0 score edges Miami's 5.1 by nearly a full point, suggesting substantially stronger performance across the measured metrics despite both cities' strong global profiles.
Seoul's 0.9-point margin is significant; most city comparisons cluster within 0.3 points, making this a meaningful gap rather than marginal difference.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Miami | Seoul | Winner |
|---|---|---|---|
| Affordability | 1.7 | 3.1 | Seoul +1.4 |
| Quality of life | 6.5 | 7.6 | Seoul +1.1 |
| Remote-work friendliness | 6.5 | 7.5 | Seoul +1.0 |
| Healthcare | 5.6 | 5.8 | Seoul +0.2 |
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%)82
- Rent index (weight 40%)85
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Miami: ((100 − 82)/100 × 0.6 + (100 − 85)/100 × 0.4) × 10 = 1.7.
Miami is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)55
- Healthcare index (weight 35%)72
- Air quality index (weight 25%)70
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Miami: (55/100 × 0.4 + 72/100 × 0.35 + 70/100 × 0.25) × 10 = 6.5.
Miami has a mixed quality profile. Safety: good; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)240 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)82
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Miami: (min(240/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 82)/100 × 0.25) × 10 = 6.5.
Miami works for remote work but isn't optimized for it: internet 240 Mbps, income tax 17%, cost index 82.
Healthcare
- Healthcare quality index (weight 70%)72
- Healthcare out-of-pocket / month (lower = better) (weight 30%)400
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Miami: (72/100 × 0.7 + max(0, 1 − 400/500) × 0.3) × 10 = 5.6.
Miami has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~400 USD/month. Cross-border insurance closes the gap.

Seoul is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)82
- Healthcare index (weight 35%)83
- 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 Seoul: (82/100 × 0.4 + 83/100 × 0.35 + 55/100 × 0.25) × 10 = 7.6.
Seoul scores excellent 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%)280 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)75
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Seoul: (min(280/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 75)/100 × 0.25) × 10 = 7.5.
Seoul combines fast internet (280 Mbps median), a 12% effective income tax and cost index 75 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)83
- Healthcare out-of-pocket / month (lower = better) (weight 30%)35000
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Seoul: (83/100 × 0.7 + max(0, 1 − 35000/500) × 0.3) × 10 = 5.8.
Seoul has trade-offs in healthcare: quality is excellent, typical out-of-pocket cost is ~35000 KRW/month. Cross-border insurance closes the gap.
Monthly cost delta: Miami vs Seoul
Normalized to USD at 1 KRW = 0.0007 USD.
| Category | Miami | Seoul | Change |
|---|---|---|---|
| housing | $3,200 | ₩1,100,000 | -75% |
| food | $600 | ₩450,000 | -45% |
| transport | $112 | ₩65,000 | -58% |

| leisure | $600 | ₩250,000 | -70% |
| healthcare | $400 | ₩35,000 | -94% |
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 food: Seoul spends 10.4 percentage points more of its budget on it (22% vs. 12%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Miami ↔ Seoul
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Miami = 82, Seoul = 75); currency-converted at 1 KRW = 0.0007 USD. Tax differences are not modeled.
| Miami gross | Seoul equivalent |
|---|---|
| $40,000 | ₩50,135,501 |
| $75,000 | ₩94,004,065 |
| $120,000 | ₩150,406,504 |

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.

Remote work logistics
Time zones and language: Miami vs Seoul
Miami (America/New_York) and Seoul (Asia/Seoul) sit 14 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: Miami observes daylight saving while Seoul doesn't, so the gap shifts by an hour part of the year.
Official: English · English: Native-equivalent · Local language: Not needed
Functionally bilingual English/Spanish. English fully sufficient but Spanish is the daily-life default in many neighborhoods (Little Havana, Hialeah, Doral).
Official: Korean · English: Moderate · Local language: Useful
Korean is the daily-life default. English usable in expat-heavy neighborhoods (Itaewon, Hannam) and international firms; outside that, limited. Hangul is easy to learn even if speaking is slow.

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: 2026-05-28 (Miami) and 2026-05-28 (Seoul).
- FX rate. 1 KRW = 0.0007 USD, 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

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 Miami 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.
