Understanding Cost of Living
Cost of living represents the amount of money needed to sustain a certain standard of living in a particular location. It encompasses housing, food, transportation, utilities, and discretionary spending.
Why Cost of Living Matters More Than Salary
A €80,000 salary in London doesn't provide the same lifestyle as €80,000 in Prague. Cost of living adjustments help you understand:
- • How much disposable income you'll actually have
- • Whether you can maintain your current lifestyle
- • How much you can save or invest
- • The real value of salary offers from different cities
Cost of Living Index Explained
Cost of living indices compare the relative expense of living in different locations. Most indices use a baseline (often set to 100) representing a reference city or average cost.
| Index Value | Meaning | Example |
|---|---|---|
| 100 | Baseline/Average | Prague (reference city) |
| 150 | 50% more expensive | London costs 50% more than Prague |
| 75 | 25% less expensive | Barcelona costs 25% less than Prague |
Major Expense Categories
Cost of living calculations typically break expenses into weighted categories. Understanding these weights helps you prioritize your research and calculations.

Calculation Methodology
The Cost of Living Formula
This formula tells you how much you'd need to earn in your target city to maintain the same standard of living as your current location.
Step-by-Step Calculation Process
Determine Your Current Living Costs
Calculate your monthly expenses in these categories:
- • Housing: rent, utilities, insurance
- • Food: groceries, restaurants
- • Transportation: public transit, car expenses
- • Entertainment: dining, activities, travel
- • Other: clothing, phone, personal care
Research Target City Costs
Use reliable sources to find equivalent costs:
- • Rental websites for housing costs
- • Local grocery stores for food prices
- • Public transport websites for transit costs
- • Local lifestyle and entertainment costs
Apply Cost of Living Index
Use established indices to adjust your calculations:
If Madrid has index 75 and Berlin has index 95:
€50,000 in Madrid = €63,333 equivalent in Berlin
Calculation: (€50,000 ÷ 75) × 95 = €63,333
Account for Personal Preferences
Adjust for your specific lifestyle and priorities:
- • Premium vs. budget lifestyle choices
- • City center vs. suburban living
- • Dining out frequency
- • Travel and entertainment preferences
Housing Cost Analysis
Housing typically represents 30-40% of your total living costs, making it the most critical factor in cost of living comparisons. Here's how to analyze housing costs effectively.
🏢 Rental Market Analysis
- Location Premium: City center vs. suburbs (20-50% difference)
- Property Type: Apartment vs. house (varies by city)
- Size Requirements: Studio to 3+ bedrooms
- Furnished vs. Unfurnished: 10-30% price difference
- Lease Terms: Short-term premium of 20-40%
⚡ Utility Costs
- Electricity: €50-200/month (usage and climate)
- Gas/Heating: €30-150/month (seasonal)
- Water: €20-60/month
- Internet: €20-60/month
- Total Utilities: often 15-25% of rent
Housing Cost Comparison Example
| City | 1BR Apartment (city centre) | Utilities (est., 1BR) | Total Housing | % of €50k Salary |
|---|---|---|---|---|
| Madrid | €1,371 | €170 | €1,541 | 37% |
| Berlin | €1,262 | €250 | €1,512 | 36% |
| London | €2,500 | €270 | €2,770 | 67% |
Analysis: With these typical figures, London needs ~89% more monthly housing budget than Berlin, which has a major impact on overall disposable income.
Notes: Rents are August 2025 city-centre 1BR averages (Numbeo). London rent shown in euros using ~€1.15/£ conversion. Utilities are conservative 1BR estimates and vary by usage and home size.

Tax rates vary dramatically between countries. Always compare net (after-tax) salaries.
❌ Using Outdated Information
Costs move fast. Use data from the last 6–12 months.
❌ Forgetting Hidden Costs
Moving expenses, visa fees, deposits, and setup costs add up.
❌ Not Accounting for Currency Fluctuations
Exchange rates change. Use current rates and consider volatility.
❌ Ignoring Lifestyle Differences
Your lifestyle may change in the new location. Adjust expectations.
