City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
Auckland edges out Brussels on the Mundevo composite, 5.8 to 5.7 out of 10 — a narrow 0.1-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 — Auckland 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 | Auckland | Brussels | Winner |
|---|---|---|---|
| Affordability | 3.6 | 4.0 | Brussels +0.4 |
| Quality of life | 7.0 | 6.1 | Auckland +0.9 |
| Remote-work friendliness | 4.9 | 4.7 | Auckland +0.2 |
| Healthcare | 7.8 | 8.1 | Brussels +0.3 |
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%)76
- Rent index (weight 40%)46
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Auckland: ((100 − 76)/100 × 0.6 + (100 − 46)/100 × 0.4) × 10 = 3.6.
Auckland 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%)73
- Air quality index (weight 25%)82
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Auckland: (60/100 × 0.4 + 73/100 × 0.35 + 82/100 × 0.25) × 10 = 7.
Auckland scores good on safety, good on healthcare and excellent on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)120 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)76
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Auckland: (min(120/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 76)/100 × 0.25) × 10 = 4.9.
Auckland works for remote work but isn't optimized for it: internet 120 Mbps, income tax 17%, cost index 76.
Healthcare
- Healthcare quality index (weight 70%)73
- Healthcare out-of-pocket / month (lower = better) (weight 30%)50
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Auckland: (73/100 × 0.7 + max(0, 1 − 50/500) × 0.3) × 10 = 7.8.
Auckland combines good system quality with a manageable out-of-pocket cost (~50 NZD/month). Travel insurance still recommended for non-residents.

- Rent index (weight 40%)40
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Brussels: ((100 − 74)/100 × 0.6 + (100 − 40)/100 × 0.4) × 10 = 4.
Brussels 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%)48
- Healthcare index (weight 35%)76
- Air quality index (weight 25%)62
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Brussels: (48/100 × 0.4 + 76/100 × 0.35 + 62/100 × 0.25) × 10 = 6.1.
Brussels 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%)120 Mbps
- Effective income tax (lower = better) (weight 30%)25.0%
- Cost-of-living (lower = better) (weight 25%)74
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Brussels: (min(120/300, 1) × 0.45 + (1 − 0.25) × 0.3 + (100 − 74)/100 × 0.25) × 10 = 4.7.
Brussels works for remote work but isn't optimized for it: internet 120 Mbps, income tax 25%, cost index 74.
Healthcare
- Healthcare quality index (weight 70%)76
- Healthcare out-of-pocket / month (lower = better) (weight 30%)30
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Brussels: (76/100 × 0.7 + max(0, 1 − 30/500) × 0.3) × 10 = 8.1.
Brussels combines good system quality with a manageable out-of-pocket cost (~30 EUR/month). Travel insurance still recommended for non-residents.
Monthly cost delta: Auckland vs Brussels
Normalized to NZD at 1 EUR = 1.8000 NZD.
| Category | Auckland | Brussels | Change |
|---|---|---|---|
| housing | NZ$2,400 | €1,100 | -18% |
| food | NZ$600 | €390 | +17% |
| transport | NZ$150 | €55 | -34% |
| utilities | NZ$240 | €210 | +57% |

| healthcare | NZ$50 | €30 | +8% |
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: Auckland spends 8.6 percentage points more of its budget on it (59% vs. 50%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: Auckland ↔ Brussels
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Auckland = 76, Brussels = 74); currency-converted at 1 EUR = 1.8000 NZD. Tax differences are not modeled.
| Auckland gross | Brussels equivalent |
|---|---|
| NZ$40,000 | €21,637 |
| NZ$75,000 | €40,570 |
| NZ$120,000 | €64,912 |
| Brussels gross | Auckland equivalent |
|---|---|
| €40,000 | NZ$73,946 |
| €75,000 | NZ$138,649 |
| €120,000 | NZ$221,838 |
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 (Auckland) and 2026-06-10 (Brussels).
- FX rate. 1 EUR = 1.8000 NZD, 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 Auckland 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.
