London edges San Francisco by 0.7 points with a 5.1 score, suggesting marginally stronger livability across measured dimensions despite San Francisco's global tech prominence.
San Francisco's 4.4 score trails most major global cities, reflecting persistent housing costs and infrastructure strain that outweigh its economic advantages.
If you're prioritizing quality of life metrics over career opportunities in tech, London's slight advantage warrants deeper investigation into specific categories like housing affordability and transit reliability.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | London | San Francisco | Winner |
|---|---|---|---|
| Affordability | 0.0 | 0.0 | London +0.0 |
| Quality of life | 6.4 | 6.0 | London +0.4 |
| Remote-work friendliness | 5.0 | 6.7 | San Francisco +1.7 |
| Healthcare | 8.3 | 5.0 | London +3.3 |
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%)113
- Rent index (weight 40%)107
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For London: ((100 − 113)/100 × 0.6 + (100 − 107)/100 × 0.4) × 10 = 0.
London 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%)60
- Healthcare index (weight 35%)75
- 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 London: (60/100 × 0.4 + 75/100 × 0.35 + 55/100 × 0.25) × 10 = 6.4.
London 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%)170 Mbps
- Effective income tax (lower = better) (weight 30%)18.0%
- Cost-of-living (lower = better) (weight 25%)113
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For London: (min(170/300, 1) × 0.45 + (1 − 0.18) × 0.3 + (100 − 113)/100 × 0.25) × 10 = 5.
London works for remote work but isn't optimized for it: internet 170 Mbps, income tax 18%, cost index 113.
Healthcare
- Healthcare quality index (weight 70%)75
- Healthcare out-of-pocket / month (lower = better) (weight 30%)0
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For London: (75/100 × 0.7 + max(0, 1 − 0/500) × 0.3) × 10 = 8.3.
London combines good system quality with a manageable out-of-pocket cost (~0 GBP/month). Travel insurance still recommended for non-residents.

San Francisco has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~500 USD/month. Cross-border insurance closes the gap.

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: San Francisco spends 8.8 percentage points more of its budget on it (9% vs. 0%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: London ↔ San Francisco
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (London = 113, San Francisco = 120); currency-converted at 1 USD = 0.7870 GBP. Tax differences are not modeled.
| London gross | San Francisco equivalent |
|---|---|
| £40,000 | $53,972 |
| £75,000 | $101,197 |
| £120,000 | $161,916 |

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: 2026-05-23 (London) and 2026-05-28 (San Francisco).
- FX rate. 1 USD = 0.7870 GBP, 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 London 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.
