The composite gap is small enough that one weighted axis can flip the result. Use the per-axis breakdown below to see which city wins your specific priorities — someone optimizing for healthcare can land on a different answer than someone optimizing for affordability.
Run the salary calculator for both cities at your target lifestyle before deciding — Lyon winning on quality doesn't mean the gross-salary requirement also lands in your favor.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Buenos Aires | Lyon | Winner |
|---|---|---|---|
| Affordability | 7.6 | 3.2 | Buenos Aires +4.4 |
| Quality of life | 5.0 | 6.8 | Lyon +1.8 |
| Remote-work friendliness | 6.2 | 6.5 | Lyon +0.3 |
| Healthcare | 4.3 | 8.4 | Lyon +4.1 |
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%)29
- Rent index (weight 40%)18
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Buenos Aires: ((100 − 28.5)/100 × 0.6 + (100 − 18)/100 × 0.4) × 10 = 7.6.
Buenos Aires 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%)38
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)52
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Buenos Aires: (38/100 × 0.4 + 62/100 × 0.35 + 52/100 × 0.25) × 10 = 5.
Buenos Aires 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%)112 Mbps
- Effective income tax (lower = better) (weight 30%)9.0%
- Cost-of-living (lower = better) (weight 25%)29
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Buenos Aires: (min(112/300, 1) × 0.45 + (1 − 0.09) × 0.3 + (100 − 28.5)/100 × 0.25) × 10 = 6.2.
Buenos Aires works for remote work but isn't optimized for it: internet 112 Mbps, income tax 9%, cost index 28.5.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)15000
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Buenos Aires: (62/100 × 0.7 + max(0, 1 − 15000/500) × 0.3) × 10 = 4.3.
Buenos Aires has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~15000 ARS/month. Cross-border insurance closes the gap.

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: 2026-07-03 (Buenos Aires) and 2026-05-28 (Lyon).
- FX rate. 1 EUR = 1050.0000 ARS, 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 Buenos Aires 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.
