How to Compare Job Offers Across Countries Using Net Salary and Cost of Living
Two job offers in different countries are almost never comparable by gross salary alone - tax systems, social contributions, and local costs all move independently of the headline number.
Convert every offer to an estimated net salary in its own country's currency before comparing anything else.
Adjust net salary for rent and everyday local costs, since the same net figure buys very different lifestyles in different places.
Factor in benefits, relocation support, and family circumstances separately - they rarely show up in a simple salary comparison but materially change the outcome.
Quick definitions
How do I compare salaries in different countries?
Convert each offer's gross salary into an estimated net salary using that country's income tax and social contribution rules, then adjust for local rent and everyday costs in the specific city. Comparing gross figures alone, or net figures without a cost-of-living adjustment, both produce misleading results.
Should I compare gross or net salary?
Net salary is the more useful figure for a real comparison, since it reflects what actually reaches your account. Gross salary is still useful for checking that pension contributions, bonuses, and other percentage-based benefits are calculated on a comparable base.
How do I include rent in a salary comparison?
Subtract a realistic rent figure for the specific city - not a country average - from each offer's estimated net monthly salary, to reach a rent-adjusted disposable income figure that is far more comparable across locations than net salary alone.
The short version
Key takeaways
Who this explains things for
Reference table
| Step | What you calculate | Why it matters |
|---|---|---|
| 1. Net salary | Gross salary converted using each country's tax rules | Removes the distortion of comparing pre-tax figures |
| 2. Rent-adjusted income | Net salary minus realistic city-specific rent | Housing is usually the largest cost difference between locations |
| 3. Everyday-cost adjustment | Rent-adjusted income minus groceries, transport, utilities | Reveals real disposable income, not just take-home pay |
| 4. Benefits and terms | Healthcare, pension, leave, relocation support reviewed separately | These rarely appear in the salary figure but change total value |
Step one: convert every offer to net salary
Before comparing anything else, convert each offer's gross salary into an estimated net salary using the tax rules of the country where it would actually be paid. The gap between gross and net salary varies significantly by country - a higher gross offer in a higher-tax country can produce a similar or even lower net salary than a lower gross offer somewhere else. See the companion guide on gross vs net salary for why this gap is not a fixed percentage.
Use a country-specific salary calculator rather than a rough percentage estimate, since income tax brackets, personal allowances, and social contribution rates differ meaningfully between countries and even a well-informed guess can be off by a wide margin.
Step two: adjust for rent and everyday costs
Once each offer has an estimated net salary, subtract a realistic rent figure for the specific city in question. This is usually the single biggest adjustment, since rent can vary dramatically even within the same country - see the companion guide on net salary vs purchasing power for a closer look at why this step changes the outcome so much.
After rent, subtract typical monthly costs for groceries, transport, and utilities to reach an estimated disposable income for each offer. This figure - not the original gross or net salary - is what should ultimately drive the comparison, since it reflects what is realistically left over each month.
Step three: factor in benefits and terms that do not show up in salary
Healthcare coverage, pension or retirement matching, paid leave entitlements, and relocation support can represent significant value that a simple salary comparison misses entirely. A lower net salary paired with strong employer-covered healthcare and a generous pension match can outperform a higher net salary with minimal benefits, depending on personal circumstances.
Relocation-specific costs are worth listing separately: visa or work-permit support, moving allowances, temporary housing, and any probation period terms. These are one-off or short-term factors rather than ongoing salary, but they can materially affect the first few months of a move and should be weighed alongside the ongoing disposable-income comparison, not folded into it.
Walkthrough example
Working through two competing international offers
A candidate has two offers in different countries with different gross salaries, tax systems, and city-level rent, and wants a fair side-by-side comparison.
A structured, step-by-step comparison - net salary, then rent, then everyday costs, then benefits - produces a far more reliable picture than comparing headline gross salaries, and often reverses which offer looks stronger at first glance.
Frequently asked questions
Quick answers to the questions people search most often on this topic.
Is it fair to compare offers using currency conversion alone?+
No. A simple currency conversion ignores both taxation and local cost of living, which are usually far more significant than the exchange rate itself. Convert to net salary and adjust for local costs in each country's own currency before making any cross-currency comparison.
What if one offer includes a relocation bonus or allowance?+
Treat a one-off relocation bonus or allowance separately from ongoing salary, since it affects only the first year (or less) rather than the recurring monthly comparison. It is still worth factoring into the overall decision, particularly if it offsets real moving costs.
Should family size change how I compare offers?+
Yes. Family-related costs - childcare, school fees, a larger home - can change the rent and everyday-cost adjustment substantially, and some countries' tax systems also treat household status differently, which changes the net salary side of the comparison as well.
Where can I estimate net salary for a specific country before comparing offers?+
Use the salary calculator on salaryincometax.com and select the relevant country to estimate net salary, total tax, and effective tax rate for each offer before beginning the rent and cost-of-living adjustment.
In short
Compare in this order, not by gross salary alone
Convert to net salary first, adjust for city-specific rent and everyday costs second, and weigh benefits and relocation terms separately. Skipping any of these steps - especially comparing by gross salary alone - is the most common way international offers get misjudged.
