Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Hong Kong | San Francisco | Winner |
|---|---|---|---|
| Affordability | 0.9 | 0.0 | Hong Kong +0.9 |
| Quality of life | 7.4 | 6.0 | Hong Kong +1.4 |
| Remote-work friendliness | 6.2 | 6.7 | San Francisco +0.5 |
| Healthcare | 5.5 | 5.0 | Hong Kong +0.5 |
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%)88
- Rent index (weight 40%)95
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Hong Kong: ((100 − 88)/100 × 0.6 + (100 − 95)/100 × 0.4) × 10 = 0.9.
Hong Kong 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%)78
- 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 Hong Kong: (82/100 × 0.4 + 78/100 × 0.35 + 55/100 × 0.25) × 10 = 7.4.
Hong Kong 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%)220 Mbps
- Effective income tax (lower = better) (weight 30%)15.0%
- Cost-of-living (lower = better) (weight 25%)88
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Hong Kong: (min(220/300, 1) × 0.45 + (1 − 0.15) × 0.3 + (100 − 88)/100 × 0.25) × 10 = 6.2.
Hong Kong works for remote work but isn't optimized for it: internet 220 Mbps, income tax 15%, cost index 88.
Healthcare
- Healthcare quality index (weight 70%)78
- Healthcare out-of-pocket / month (lower = better) (weight 30%)1200
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Hong Kong: (78/100 × 0.7 + max(0, 1 − 1200/500) × 0.3) × 10 = 5.5.
Hong Kong has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~1200 HKD/month. Cross-border insurance closes the gap.

Quality of life
- Safety index (weight 40%)45
- Healthcare index (weight 35%)72
- Air quality index (weight 25%)68
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For San Francisco: (45/100 × 0.4 + 72/100 × 0.35 + 68/100 × 0.25) × 10 = 6.
San Francisco 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%)280 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)120
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For San Francisco: (min(280/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 120)/100 × 0.25) × 10 = 6.7.
San Francisco works for remote work but isn't optimized for it: internet 280 Mbps, income tax 17%, cost index 120.
Healthcare
- Healthcare quality index (weight 70%)72
- 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 San Francisco: (72/100 × 0.7 + max(0, 1 − 500/500) × 0.3) × 10 = 5.
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.
Monthly cost delta: Hong Kong vs San Francisco
Normalized to HKD at 1 USD = 7.8241 HKD.
| Category | Hong Kong | San Francisco | Change |
|---|---|---|---|
| housing | HK$22,000 | $3,500 | +24% |
| food | HK$6,000 | $700 | -9% |

| leisure | HK$5,500 | $700 | -0% |
| healthcare | HK$1,200 | $500 | +226% |
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 5.6 percentage points more of its budget on it (9% vs. 3%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Hong Kong ↔ San Francisco
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Hong Kong = 88, San Francisco = 120); currency-converted at 1 USD = 7.8241 HKD. Tax differences are not modeled.
| Hong Kong gross | San Francisco equivalent |
|---|---|
| HK$40,000 | $6,971 |
| HK$75,000 | $13,072 |
| HK$120,000 | $20,914 |

| $40,000 | HK$229,506 |
| $75,000 | HK$430,324 |
| $120,000 | HK$688,519 |
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.

Remote work logistics
Time zones and language: Hong Kong vs San Francisco
Hong Kong (Asia/Hong_Kong) and San Francisco (America/Los_Angeles) sit 16 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: San Francisco observes daylight saving while Hong Kong doesn't, so the gap shifts by an hour part of the year.
Official: Cantonese, English · English: High · Local language: Not needed
English is the working language in business and government; Cantonese dominates daily street-level interactions but English usability across the city is among the highest of any non-Anglophone Asian market.
Official: English · English: Native-equivalent · Local language: Not needed
English-native. Significant Spanish and Mandarin presence in specific neighborhoods (Mission, Chinatown). English universal.

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 (Hong Kong) and 2026-05-28 (San Francisco).
- FX rate. 1 USD = 7.8241 HKD, 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 Hong Kong 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.
