Seoul is the bigger city: about 9.7M people versus Santiago's 5.6M — roughly 1.7× larger.
City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
Seoul edges Santiago by 0.4 points, suggesting marginal differences in core livability metrics despite vastly different geographies and development models.
At 6.0 versus 5.6, Seoul's advantage is narrower than the gap between either city and typical tier-two metros, indicating both punch above their weight class.
Examine what Seoul does better in specific domains—transit, housing, wages—rather than treating the score difference as meaningful overall superiority.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
| Axis | Santiago | Seoul | Winner |
|---|---|---|---|
| Affordability | 6.2 | 3.1 | Santiago +3.1 |
| Quality of life | 4.6 | 7.6 | Seoul +3.0 |
| Remote-work friendliness | 6.8 | 7.5 | Seoul +0.7 |
| Healthcare | 4.6 | 5.8 | Seoul +1.2 |
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%)48
- Rent index (weight 40%)22
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Santiago: ((100 − 48)/100 × 0.6 + (100 − 22)/100 × 0.4) × 10 = 6.2.
Santiago is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)35
- Healthcare index (weight 35%)65
- Air quality index (weight 25%)35
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Santiago: (35/100 × 0.4 + 65/100 × 0.35 + 35/100 × 0.25) × 10 = 4.6.
Santiago 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%)180 Mbps
- Effective income tax (lower = better) (weight 30%)8.0%
- Cost-of-living (lower = better) (weight 25%)48
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Santiago: (min(180/300, 1) × 0.45 + (1 − 0.08) × 0.3 + (100 − 48)/100 × 0.25) × 10 = 6.8.
Santiago works for remote work but isn't optimized for it: internet 180 Mbps, income tax 8%, cost index 48.
Healthcare
- Healthcare quality index (weight 70%)65
- Healthcare out-of-pocket / month (lower = better) (weight 30%)60000
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Santiago: (65/100 × 0.7 + max(0, 1 − 60000/500) × 0.3) × 10 = 4.6.
Santiago has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~60000 CLP/month. Cross-border insurance closes the gap.

Affordability
- Cost-of-living index (weight 60%)75
- Rent index (weight 40%)60
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Seoul: ((100 − 75)/100 × 0.6 + (100 − 60)/100 × 0.4) × 10 = 3.1.
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: Santiago vs Seoul
Normalized to CLP at 1 KRW = 0.6959 CLP.
| Category | Santiago | Seoul | Change |
|---|---|---|---|
| housing | CLP 480,000 | ₩1,100,000 | +59% |
| food | CLP 220,000 | ₩450,000 | +42% |
| transport | CLP 40,000 | ₩65,000 | +13% |
| utilities | CLP 110,000 | ₩140,000 | -11% |
| leisure | CLP 240,000 | ₩250,000 | -28% |
| healthcare | CLP 60,000 | ₩35,000 | -59% |
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: Seoul spends 12.2 percentage points more of its budget on it (54% vs. 42%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: Santiago ↔ Seoul
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Santiago = 48, Seoul = 75); currency-converted at 1 KRW = 0.6959 CLP. Tax differences are not modeled.
| Santiago gross | Seoul equivalent |
|---|---|
| CLP 40,000 | ₩89,806 |
| CLP 75,000 | ₩168,386 |
| CLP 120,000 | ₩269,417 |
| Seoul gross | Santiago equivalent |

| ₩40,000 | CLP 17,816 |
| ₩75,000 | CLP 33,405 |
| ₩120,000 | CLP 53,449 |
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.

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 (Santiago) and 2026-05-28 (Seoul).
- FX rate. 1 KRW = 0.6959 CLP, 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.

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 Santiago 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.
