JohannesburgIstanbul vs Johannesburg: cost, size & quality of life compared
Istanbul (composite 5.5) vs Johannesburg (composite 5.1). 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 0.4 points
Population & size
Is Istanbul bigger than Johannesburg?
Istanbul is the bigger city: about 16M people versus Johannesburg's 4.4M — roughly 3.5× 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 Johannesburg on the Mundevo composite, 5.5 to 5.1 out of 10 — a narrow 0.4-point margin across safety, healthcare, air quality and cost.
The composite gap is small enough that one weighted axis can flip the result. Use the per-axis breakdown below to see which city wins your specific priorities — someone optimizing for healthcare can land on a different answer than someone optimizing for affordability.
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 | Johannesburg | Winner |
|---|---|---|---|
| Affordability | 6.9 | 7.0 | Johannesburg +0.1 |
| Quality of life | 5.6 | 4.2 | Istanbul +1.4 |
| Remote-work friendliness | 4.7 | 4.9 | Johannesburg +0.2 |
| Healthcare | 4.8 | 4.3 | Istanbul +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%)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.

Affordability
- Cost-of-living index (weight 60%)39
- Rent index (weight 40%)16
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Johannesburg: ((100 − 39)/100 × 0.6 + (100 − 16)/100 × 0.4) × 10 = 7.
Johannesburg sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)18
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)52
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Johannesburg: (18/100 × 0.4 + 62/100 × 0.35 + 52/100 × 0.25) × 10 = 4.2.
Johannesburg has a mixed quality profile. Safety: poor; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)60 Mbps
- Effective income tax (lower = better) (weight 30%)18.0%
- Cost-of-living (lower = better) (weight 25%)39
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Johannesburg: (min(60/300, 1) × 0.45 + (1 − 0.18) × 0.3 + (100 − 39)/100 × 0.25) × 10 = 4.9.
Johannesburg works for remote work but isn't optimized for it: internet 60 Mbps, income tax 18%, cost index 39.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)800
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Johannesburg: (62/100 × 0.7 + max(0, 1 − 800/500) × 0.3) × 10 = 4.3.
Johannesburg has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~800 ZAR/month. Cross-border insurance closes the gap.
Monthly cost delta: Istanbul vs Johannesburg
Normalized to TRY at 1 ZAR = 2.1000 TRY.
| Category | Istanbul | Johannesburg | Change |
|---|---|---|---|
| housing | TRY 22,000 | ZAR 9,000 | -14% |
| food | TRY 9,500 | ZAR 5,000 | +11% |
| transport | TRY 900 | ZAR 1,100 | +157% |
| utilities | TRY 2,800 | ZAR 2,500 | +88% |
| leisure | TRY 8,500 | ZAR 4,500 | +11% |
| healthcare | TRY 1,500 | ZAR 800 | +12% |
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: Istanbul spends 9.4 percentage points more of its budget on it (49% vs. 39%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: Istanbul ↔ Johannesburg
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Istanbul = 38, Johannesburg = 39); currency-converted at 1 ZAR = 2.1000 TRY. Tax differences are not modeled.
| Istanbul gross | Johannesburg equivalent |
|---|---|
| TRY 40,000 | ZAR 19,549 |
| TRY 75,000 | ZAR 36,654 |
| TRY 120,000 | ZAR 58,647 |
| Johannesburg gross | Istanbul equivalent |
|---|---|
| ZAR 40,000 | TRY 81,846 |
| ZAR 75,000 | TRY 153,462 |
| ZAR 120,000 | TRY 245,538 |
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 2026-06-10 (Johannesburg).
- FX rate. 1 ZAR = 2.1000 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.
