San FranciscovsSeattleSan Francisco vs Seattle: cost, quality of life, and the winner
San Francisco (composite 4.4) vs Seattle (composite 5.0). Side-by-side on affordability, quality of life, remote-work friendliness and healthcare — with the calculation behind each score.
Composite scores
Overall: Seattle wins by 0.6 points
Seattle pulls ahead with a 5.0 score versus San Francisco's 4.4, a meaningful 0.6-point gap that reflects measurable differences in livability metrics or quality-of-life factors.
While both are Pacific Northwest tech hubs, Seattle's edge suggests it offers tangible advantages—whether cost-of-living relief, housing availability, or civic infrastructure—that San Francisco hasn't matched.
If you're weighing these cities, examine the specific scoring criteria behind Seattle's lead: dig into housing costs, transit quality, and job market stability to see which factors matter most for your move.
Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
| Axis | San Francisco | Seattle | Winner |
|---|---|---|---|
| Affordability | 0.0 | 1.0 | Seattle +1.0 |
| Quality of life | 6.0 | 6.7 | Seattle +0.7 |
| Remote-work friendliness | 6.7 | 7.2 | Seattle +0.5 |
| Healthcare | 5.0 | 5.2 | Seattle +0.2 |
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%)120
- Rent index (weight 40%)115
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For San Francisco: ((100 − 120)/100 × 0.6 + (100 − 115)/100 × 0.4) × 10 = 0.
San Francisco 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%)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.
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%)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: San Francisco vs Seattle
Normalized to USD at 1 USD = 1.0000 USD.
| Category | San Francisco | Seattle | Change |
|---|---|---|---|
| housing | $3,500 | $2,800 | -20% |
| food | $700 | $650 | -7% |
| transport | $80 | $100 | +25% |

| leisure | $700 | $650 | -7% |
| healthcare | $500 | $500 | +0% |
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 housing: San Francisco spends 4.5 percentage points more of its budget on it (62% vs. 57%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: San Francisco ↔ Seattle
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (San Francisco = 120, Seattle = 92); currency-converted at 1 USD = 1.0000 USD. Tax differences are not modeled.
| San Francisco gross | Seattle equivalent |
|---|---|
| $40,000 | $30,667 |
| $75,000 | $57,500 |
| $120,000 | $92,000 |
| Seattle gross | San Francisco equivalent |
|---|---|
| $40,000 | $52,174 |
| $75,000 | $97,826 |
| $120,000 | $156,522 |
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: 2026-05-28 (San Francisco) and 2026-05-28 (Seattle).
- FX rate. 1 USD = 1.0000 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.

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 San Francisco 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.
