Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Chicago | Porto | Winner |
|---|---|---|---|
| Affordability | 2.5 | 4.9 | Porto +2.4 |
| Quality of life | 5.9 | 7.4 | Porto +1.5 |
| Remote-work friendliness | 6.8 | 6.3 | Chicago +0.5 |
| Healthcare | 5.3 | 7.5 | Porto +2.2 |
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%)78
- Rent index (weight 40%)70
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Chicago: ((100 − 78)/100 × 0.6 + (100 − 70)/100 × 0.4) × 10 = 2.5.
Chicago 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%)45
- Healthcare index (weight 35%)72
- Air quality index (weight 25%)65
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Chicago: (45/100 × 0.4 + 72/100 × 0.35 + 65/100 × 0.25) × 10 = 5.9.
Chicago has a mixed quality profile. Safety: fair; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)250 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)78
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Chicago: (min(250/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 78)/100 × 0.25) × 10 = 6.8.
Chicago works for remote work but isn't optimized for it: internet 250 Mbps, income tax 17%, cost index 78.
Healthcare
- Healthcare quality index (weight 70%)72
- Healthcare out-of-pocket / month (lower = better) (weight 30%)450
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Chicago: (72/100 × 0.7 + max(0, 1 − 450/500) × 0.3) × 10 = 5.3.
Chicago has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~450 USD/month. Cross-border insurance closes the gap.

Porto 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%)80
- Healthcare index (weight 35%)70
- 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 Porto: (80/100 × 0.4 + 70/100 × 0.35 + 70/100 × 0.25) × 10 = 7.4.
Porto scores excellent on safety, good on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)190 Mbps
- Effective income tax (lower = better) (weight 30%)20.0%
- Cost-of-living (lower = better) (weight 25%)58
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Porto: (min(190/300, 1) × 0.45 + (1 − 0.2) × 0.3 + (100 − 58)/100 × 0.25) × 10 = 6.3.
Porto works for remote work but isn't optimized for it: internet 190 Mbps, income tax 20%, cost index 58.
Healthcare
- Healthcare quality index (weight 70%)70
- Healthcare out-of-pocket / month (lower = better) (weight 30%)65
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Porto: (70/100 × 0.7 + max(0, 1 − 65/500) × 0.3) × 10 = 7.5.
Porto combines good system quality with a manageable out-of-pocket cost (~65 EUR/month). Travel insurance still recommended for non-residents.

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: Chicago spends 6.9 percentage points more of its budget on it (11% vs. 4%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Chicago ↔ Porto
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Chicago = 78, Porto = 58); currency-converted at 1 EUR = 1.0800 USD. Tax differences are not modeled.
| Chicago gross | Porto equivalent |
|---|---|
| $40,000 | €27,540 |
| $75,000 | €51,638 |
| $120,000 | €82,621 |

| €120,000 | $174,290 |
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: Chicago vs Porto
Chicago (America/Chicago) and Porto (Europe/Lisbon) sit 6 hours apart in standard time. A 9-to-5 in one overlaps the other's for 2 hours a day.
Official: English · English: Native-equivalent · Local language: Not needed
English-native, extremely multicultural. Spanish strong in Pilsen / Little Village; Polish heritage on the north side. English universal.
Official: Portuguese · English: Moderate · Local language: Useful
More Portuguese-required than Lisbon — smaller expat infrastructure means English carries less far in everyday life. Bureaucracy is Portuguese-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: 2026-05-28 (Chicago) and 2026-05-23 (Porto).
- FX rate. 1 EUR = 1.0800 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
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 Chicago 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.
