What Cost of Living Numbers Miss
Cost of living comparisons give a starting point. But averages hide wide variation. Some costs never appear in the data at all. Understanding these gaps helps you build a more realistic picture.

This page explains what typical cost-of-living data often leaves out.
- Why averages can be misleading for individual planning
- Costs that rarely appear in comparison sites
- How lifestyle choices affect actual spending
- Why the same city costs different people different amounts
- What to research beyond headline numbers
Key tradeoffs
Important considerations that affect most people in this situation.
Cost-of-Living Data Strengths
- • Useful for rough city comparisons
- • Captures common recurring expenses
- • Provides baseline for discussion
- • Helps identify expensive vs affordable regions
Cost-of-Living Data Gaps
- • Averages hide wide variation
- • Misses one-time setup costs
- • Often excludes healthcare and insurance
- • Does not account for lifestyle differences
Averages hide wide variation
A city's 'average rent' might combine central luxury apartments with distant studio flats. The number you see may not reflect what you would actually pay.
Within a single city, rent can vary 2-3x between neighborhoods. The average tells you little about specific areas.
The same applies to food, transport, and other categories. Your actual costs depend on choices the average cannot capture.
Setup costs rarely appear in comparisons
Moving abroad involves one-time expenses that ongoing cost data misses.
Rental deposits often require 2-3 months rent upfront. This can mean thousands before you even move in.
Furniture costs if apartments are unfurnished. Basic setup can cost as much as several months of rent.
Agency fees, connection fees for utilities, and bureaucratic costs add up. These are real expenses that do not appear in monthly comparisons.
- Rental deposits (often 2-3 months)
- Agency or finder fees
- Furniture and household items
- Utility connection fees
- Administrative and legal fees
- Moving and shipping costs
Healthcare often excluded or underestimated
Many cost comparisons focus on daily expenses. Healthcare and insurance may be missing entirely or reduced to a token line item.
Insurance premiums vary widely by age, health, and coverage level. A 25-year-old and a 55-year-old face very different costs.
Out-of-pocket medical expenses are hard to predict. Dental work, prescriptions, and unexpected care can add substantially to costs.
Lifestyle differences change everything
Two people in the same city can spend vastly different amounts. Eating out daily versus cooking at home. Central apartment versus suburban flat. Car versus public transit.
Cost data assumes some 'typical' lifestyle that may not match yours. If you work from home, commute costs matter less. If you entertain often, restaurant prices matter more.
Your spending patterns from home may not translate directly. Some habits cost more abroad. Others cost less. The net effect is personal.
Currency fluctuations affect your real costs
If your income is in one currency and expenses in another, exchange rates matter. A 10% currency shift changes your effective cost of living by 10%.
Cost comparisons are snapshots at one exchange rate. By the time you move, the rate may have changed significantly.
This is especially relevant for remote workers paid in one currency while living in another. Your real costs move with exchange rates.
Quality differences hide in the numbers
A €1,000 apartment in one city may be very different from a €1,000 apartment in another. Size, condition, location, and amenities vary.
Food prices may be lower, but product quality or selection may differ. 'Cheaper' does not always mean 'equivalent but less expensive.'
Services can be cheaper but slower, less convenient, or lower quality. The tradeoff matters but does not appear in price data.
Tax situations are too complex for simple comparisons
Income tax rates vary by country, income level, and residency status. A headline tax rate tells you little about your actual burden.
Social contributions, local taxes, and other levies add to the picture. Some countries have low income tax but high other taxes.
Tax treaties, foreign income rules, and residency thresholds create complexity that simple comparisons cannot capture.
Data age matters more than you think
Cost of living changes. Rents in popular cities can rise 10-20% in a single year. Data from even two years ago may be significantly off.
Exchange rates at data collection time may differ from current rates. This compounds the age problem.
Check when data was collected. Recent data is more useful than older data, even from a 'reliable' source.
What to research beyond headline numbers
Better planning requires going beyond cost indices.
Talking to people already living there provides better data than aggregated averages. Expat forums, social media groups, and direct contacts give practical information.
- Current rental listings in your target neighborhoods
- Actual utility costs from people living there
- Healthcare and insurance premiums for your situation
- One-time setup costs specific to your destination
- Currency trends over the past 1-2 years
- Recent price changes in major categories
