Distance
How far is Istanbul from Seattle?
Istanbul is about 9,760 km (6,070 mi) from Seattle in a straight line — roughly 12 h 15 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Istanbul warmer than Seattle?
Istanbul is the warmer city: January highs average 9°C vs 7°C, and July 29°C vs 24°C. Annual sunshine is comparable between the two.
| Month | Istanbul | Seattle |
|---|---|---|
| January (high / low) | 9° / 4°C | 7° / 2°C |
| July (high / low) | 29° / 20°C | 24° / 14°C |
Borderline Mediterranean — warm dry summers, cool wet winters with occasional snow off the Black Sea. The two seas moderate extremes; wind is constant.
Oceanic. Famously gray and damp Oct-May, dry warm summers Jun-Sep. Year-round temperatures moderate; snow rare in the city itself.
Istanbul edges out Seattle on the Mundevo composite, 5.5 to 5.0 out of 10 — a decisive 0.5-point margin across safety, healthcare, air quality and cost.
A 0.5-point composite gap is large enough that the result holds across most reasonable axis re-weightings. Still worth scanning the per-axis breakdown if you have a non-default priority (e.g. air quality matters more to you than the default 25% weight).
Run the salary calculator for both cities at your target lifestyle before deciding — Istanbul winning on quality doesn't mean the gross-salary requirement also lands in your favor. If you're on a balanced tier, the cost-of-living pages for each city carry the full monthly basket and the gross-salary figure.
Data signals
What separates Istanbul and Seattle
How decisive
Istanbul comes out ahead by 0.5 composite points — a narrow edge.
Biggest difference

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Istanbul | Seattle | Winner |
|---|---|---|---|
| Affordability | 6.9 | 1.0 | Istanbul +5.9 |
| Quality of life | 5.6 | 6.7 | Seattle +1.1 |
| Remote-work friendliness | 4.7 | 7.2 | Seattle +2.5 |
| Healthcare | 4.8 | 5.2 | Seattle +0.4 |
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%)38
- Rent index (weight 40%)20
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Istanbul: ((100 − 38)/100 × 0.6 + (100 − 20)/100 × 0.4) × 10 = 6.9.
Istanbul is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)52
- Healthcare index (weight 35%)68
- Air quality index (weight 25%)45
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Istanbul: (52/100 × 0.4 + 68/100 × 0.35 + 45/100 × 0.25) × 10 = 5.6.
Istanbul 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%)40 Mbps
- Effective income tax (lower = better) (weight 30%)15.0%
- Cost-of-living (lower = better) (weight 25%)38
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Istanbul: (min(40/300, 1) × 0.45 + (1 − 0.15) × 0.3 + (100 − 38)/100 × 0.25) × 10 = 4.7.
Istanbul works for remote work but isn't optimized for it: internet 40 Mbps, income tax 15%, cost index 38.
Healthcare
- Healthcare quality index (weight 70%)68
- Healthcare out-of-pocket / month (lower = better) (weight 30%)1500
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Istanbul: (68/100 × 0.7 + max(0, 1 − 1500/500) × 0.3) × 10 = 4.8.
Istanbul has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~1500 TRY/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: Istanbul vs Seattle
Normalized to TRY at 1 USD = 38.8889 TRY.
| Category | Istanbul | Seattle | Change |
|---|---|---|---|
| housing | TRY 22,000 | $2,800 | +395% |
| food | TRY 9,500 | $650 | +166% |

| leisure | TRY 8,500 | $650 | +197% |
| healthcare | TRY 1,500 | $500 | +1196% |
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: Seattle spends 8.5 percentage points more of its budget on it (57% vs. 49%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Istanbul ↔ Seattle
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Istanbul = 38, Seattle = 92); currency-converted at 1 USD = 38.8889 TRY. Tax differences are not modeled.
| Istanbul gross | Seattle equivalent |
|---|---|
| TRY 40,000 | $2,490 |
| TRY 75,000 | $4,669 |
| TRY 120,000 | $7,471 |
| Seattle gross | Istanbul equivalent |

| $75,000 | TRY 1,204,710 |
| $120,000 | TRY 1,927,536 |
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.

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: 2026-06-10 (Istanbul) and 2026-05-28 (Seattle).
- FX rate. 1 USD = 38.8889 TRY, 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 Istanbul 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.
