Istanbul vs London: cost, size & quality of life compared
Istanbul (composite 5.5) vs London (composite 4.9). Side-by-side on cost of living, population & size, affordability, quality of life, remote-work friendliness and healthcare — with the calculation behind each score.
Composite scores
Overall: Istanbul wins by 0.6 points
Population & size
Is Istanbul bigger than London?
Istanbul is the bigger city: about 16M people versus London's 9.0M — roughly 1.7× larger.
City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
Istanbul edges out London on the Mundevo composite, 5.5 to 4.9 out of 10 — a decisive 0.6-point margin across safety, healthcare, air quality and cost.
A 0.6-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.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
| Axis | Istanbul | London | Winner |
|---|---|---|---|
| Affordability | 6.9 | 0.0 | Istanbul +6.9 |
| Quality of life | 5.6 | 6.4 | London +0.8 |
| Remote-work friendliness | 4.7 | 5.0 | London +0.3 |
| Healthcare | 4.8 | 8.3 | London +3.5 |
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%)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%)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.
Monthly cost delta: Istanbul vs London
Normalized to TRY at 1 GBP = 49.4118 TRY.
| Category | Istanbul | London | Change |
|---|---|---|---|
| housing | TRY 22,000 | £2,200 | +394% |
| food | TRY 9,500 | £450 | +134% |
| transport | TRY 900 | £180 | +888% |
| utilities | TRY 2,800 | £220 | +288% |
| leisure | TRY 8,500 | £500 | +191% |
| healthcare | TRY 1,500 | £0 | -100% |
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: London spends 13.3 percentage points more of its budget on it (62% vs. 49%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: Istanbul ↔ London
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Istanbul = 38, London = 113); currency-converted at 1 GBP = 49.4118 TRY. Tax differences are not modeled.
| Istanbul gross | London equivalent |
|---|---|
| TRY 40,000 | £2,407 |
| TRY 75,000 | £4,514 |
| TRY 120,000 | £7,222 |
| London gross | Istanbul equivalent |
|---|---|
| £40,000 | TRY 664,654 |
| £75,000 | TRY 1,246,226 |
| £120,000 | TRY 1,993,961 |
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: 2026-06-10 (Istanbul) and 2026-05-23 (London).
- FX rate. 1 GBP = 49.4118 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.

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.
