Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Copenhagen | Seattle | Winner |
|---|---|---|---|
| Affordability | 0.6 | 1.0 | Seattle +0.4 |
| Quality of life | 7.9 | 6.7 | Copenhagen +1.2 |
| Remote-work friendliness | 4.9 | 7.2 | Seattle +2.3 |
| Healthcare | 7.6 | 5.2 | Copenhagen +2.4 |
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%)106
- Rent index (weight 40%)86
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Copenhagen: ((100 − 106)/100 × 0.6 + (100 − 86)/100 × 0.4) × 10 = 0.6.
Copenhagen 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%)75
- Healthcare index (weight 35%)83
- Air quality index (weight 25%)78
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Copenhagen: (75/100 × 0.4 + 83/100 × 0.35 + 78/100 × 0.25) × 10 = 7.9.
Copenhagen 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%)200 Mbps
- Effective income tax (lower = better) (weight 30%)37.0%
- Cost-of-living (lower = better) (weight 25%)106
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Copenhagen: (min(200/300, 1) × 0.45 + (1 − 0.37) × 0.3 + (100 − 106)/100 × 0.25) × 10 = 4.9.
Copenhagen works for remote work but isn't optimized for it: internet 200 Mbps, income tax 37%, cost index 106.
Healthcare
- Healthcare quality index (weight 70%)83
- Healthcare out-of-pocket / month (lower = better) (weight 30%)200
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Copenhagen: (83/100 × 0.7 + max(0, 1 − 200/500) × 0.3) × 10 = 7.6.
Copenhagen combines excellent system quality with a manageable out-of-pocket cost (~200 DKK/month). Travel insurance still recommended for non-residents.

Affordability
- Cost-of-living index (weight 60%)92
- Rent index (weight 40%)88
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Seattle: ((100 − 92)/100 × 0.6 + (100 − 88)/100 × 0.4) × 10 = 1.
Seattle 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%)75
- Air quality index (weight 25%)75
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Seattle: (55/100 × 0.4 + 75/100 × 0.35 + 75/100 × 0.25) × 10 = 6.7.
Seattle 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%)300 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)92
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Seattle: (min(300/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 92)/100 × 0.25) × 10 = 7.2.
Seattle combines fast internet (300 Mbps median), a 17% effective income tax and cost index 92 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)75
- Healthcare out-of-pocket / month (lower = better) (weight 30%)500
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Seattle: (75/100 × 0.7 + max(0, 1 − 500/500) × 0.3) × 10 = 5.2.
Seattle has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~500 USD/month. Cross-border insurance closes the gap.
Monthly cost delta: Copenhagen vs Seattle
Normalized to DKK at 1 USD = 6.9074 DKK.
| Category | Copenhagen | Seattle | Change |
|---|---|---|---|
| housing | DKK 12,500 | $2,800 | +55% |
| food | DKK 3,500 | $650 | +28% |
| transport | DKK 470 | $100 | +47% |
| utilities | DKK 1,200 | $200 | +15% |
| leisure | DKK 3,000 | $650 | +50% |
| healthcare | DKK 200 | $500 | +1627% |
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 healthcare: Seattle spends 9.2 percentage points more of its budget on it (10% vs. 1%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Copenhagen ↔ Seattle
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Copenhagen = 106, Seattle = 92); currency-converted at 1 USD = 6.9074 DKK. Tax differences are not modeled.
| Copenhagen gross | Seattle equivalent |
|---|---|
| DKK 40,000 | $5,026 |
| DKK 75,000 | $9,424 |
| DKK 120,000 | $15,078 |
| Seattle gross | Copenhagen equivalent |

| $40,000 | DKK 318,341 |
| $75,000 | DKK 596,890 |
| $120,000 | DKK 955,024 |
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.

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 (Copenhagen) and 2026-05-28 (Seattle).
- FX rate. 1 USD = 6.9074 DKK, 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 Copenhagen 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.
