That 30% salary increase in Dubai might actually leave you worse off than a flat offer in Lisbon — once you factor in housing, healthcare, pension, and exit costs. A raw salary comparison tells you almost nothing. The financial reality of an overseas job offer only becomes clear when you score it across seven distinct factors — each of which can swing the outcome by thousands of dollars per year.
This post is a decision framework, not a calculation guide. If you want to understand how to calculate net salary abroad step by step, see our guide on how to calculate net salary abroad for expats. What this post answers is different: given all the numbers, should you actually take the job?

The 7-Factor Financial Framework
Before diving into each factor, here is the scoring system. For each factor, assign a score from -2 to +2 based on your situation:
| Score | Meaning |
|---|---|
| +2 | Strongly in your favour — significantly better than your current situation |
| +1 | Slightly better than your current situation |
| 0 | Roughly neutral — no significant difference |
| -1 | Slightly worse — manageable, but a real cost or risk |
| -2 | Significantly worse — a serious financial downside |
Total score interpretation:
| Total Score | Interpretation |
|---|---|
| +10 to +14 | Exceptional financial case — take it |
| +5 to +9 | Strong financial case — likely worth it |
| +1 to +4 | Marginal — non-financial factors should decide |
| -1 to +0 | Neutral to weak — require major non-financial upside |
| -2 to -6 | Negative financial case — requires a compelling non-financial reason |
| Below -6 | Clear financial loss — would need extraordinary circumstances |
Work through each factor, assign a score, and sum them. Do this for the actual numbers, not your intuitions about the numbers.
Factor 1: Net Salary Difference
What to measure: The difference between your current net (take-home) pay and your projected net pay in the new role after local taxes and social contributions.
Why this matters: Employers typically advertise gross salary. Across different countries, the gap between gross and net can vary by 20–40 percentage points. An offer that looks like a 30% raise in gross terms may be only a 5% raise — or a pay cut — in net terms.
How to calculate:
- Calculate your current annual net pay (what lands in your account after all deductions)
- Use the destination country's tax system to estimate your net pay from the offered gross salary (see ShouldIMove.co calculator for a quick estimate across 25+ countries)
- Compare the annual net difference
Scoring guide:
| Net salary change | Score |
|---|---|
| +30% or more | +2 |
| +15% to +29% | +1 |
| -15% to +14% | 0 |
| -16% to -30% | -1 |
| More than -30% | -2 |
Common trap: Comparing gross-to-gross. If you currently earn 45,000 EUR gross in Madrid (net ~€30,000) and receive an offer for 75,000 EUR gross in Amsterdam (net ~€47,000), the net gain is €17,000/year — a strong +1 or +2. But if you compare gross to gross and celebrate a 67% raise without running the net numbers, you might accept an offer that is less transformative than it appeared.
Tool: Use ShouldIMove.co/compare/madrid/amsterdam to see the net salary impact side by side.
Factor 2: Cost of Living Delta
What to measure: The difference in your actual monthly expenses between your current city and the destination city — specifically rent, food, transport, and utilities. Healthcare costs where applicable.
Why this matters: Net salary is only meaningful relative to what you spend. A €47,000 net salary in Amsterdam and a €30,000 net salary in Lisbon do not have the same purchasing power. Amsterdam's costs can consume that extra €17,000 in a year.
How to calculate:
Build a budget for both cities based on your actual lifestyle (not what you assume costs are — actual prices):
| Category | Current City | Destination City |
|---|---|---|
| Rent (1-bed, your area) | ||
| Groceries | ||
| Transport (monthly pass) | ||
| Utilities + internet | ||
| Health insurance (if any) | ||
| Total basic monthly costs | ||
| Monthly disposable income |
The OECD Better Life Index and Eurostat Living Conditions data provide country-level cost comparisons that can anchor your estimates.
Scoring guide:
| Change in monthly disposable income | Score |
|---|---|
| +€600/month or more | +2 |
| +€200 to +€599/month | +1 |
| -€199 to +€199/month | 0 |
| -€200 to -€599/month | -1 |
| -€600/month or more | -2 |
Example trap: A 30% salary increase in a city with 50% higher rents may leave you with less disposable income than before. Amsterdam's median 1-bedroom rent (€1,800+/month) versus Madrid (€1,300/month) is a €500/month difference that directly reduces the value of the salary increase.
Factor 3: Tax Transition Costs
What to measure: The one-time and near-term financial costs of changing your tax residency — exit taxes, double-filing obligations, social security gaps, and the cost of specialist tax advice during the transition year.
Why this matters: Year 1 of an international move is almost always financially expensive from a tax perspective. You may owe taxes in two countries simultaneously. You may lose social security credit. You may face an exit tax. These costs can easily reach €5,000–€20,000 and are rarely discussed in offer negotiations.
Key transition tax risks:
Exit taxes: Some countries tax unrealized capital gains on assets when you leave. Germany has an exit tax on shares held in foreign companies above a threshold. Netherlands has an exit levy. If you hold significant investments, check whether your country of origin applies an exit charge.
Double-filing year: Most countries trigger tax residency after 183 days. If you move in July, you may owe income tax in both your origin and destination country for that year. Tax treaty credits reduce (not always eliminate) double payment.
Social security gaps: If you leave a country partway through the year, you may not qualify for a full year's pension credit. Accumulated pension entitlements may or may not be transferable — check bilateral social security agreements.
Tax advisor cost: An international tax specialist typically charges €2,000–€5,000 for a full transition year consultation. This is non-optional for a compliant move. Budget for it.
Scoring guide:
| Estimated transition tax cost | Score |
|---|---|
| Under €2,000 total | +1 |
| €2,000–€5,000 | 0 |
| €5,000–€15,000 | -1 |
| Over €15,000 | -2 |
Note: If your employer offers tax equalization support (covering any extra taxes you incur during the move), upgrade this score by +1.
Factor 4: Relocation One-Time Costs
What to measure: All upfront, non-recurring expenses required to make the move happen. Visa fees, shipping, temporary housing, security deposits, flights for the family.
Why this matters: A one-time cost of €20,000 takes months to recoup even with a significant salary increase. Most people underestimate relocation costs by 50–100% because they focus on flights and shipping while forgetting about deposits, agent fees, and temporary housing.
Full relocation cost checklist:
| Cost Category | Low Estimate | High Estimate |
|---|---|---|
| Visa / work permit fees | €500 | €5,000 |
| Immigration lawyer | €1,000 | €3,000 |
| Temporary housing (1–3 months) | €2,000 | €9,000 |
| Security deposit (1–2 months rent) | €1,200 | €4,000 |
| Shipping / storage | €1,500 | €10,000 |
| Flights (family) | €500 | €3,000 |
| Home search trip | €500 | €2,000 |
| Lease break / early exit penalty | €0 | €5,000 |
| Setup costs (furniture, appliances) | €500 | €5,000 |
| Total | €7,700 | €46,000 |
Scoring guide: Score this relative to how many months of net salary gain the relocation costs represent.
| Months of net salary gain consumed by one-time costs | Score |
|---|---|
| Under 1 month | +1 |
| 1–3 months | 0 |
| 3–6 months | -1 |
| Over 6 months | -2 |
Employer support matters: If the employer covers visa fees, temporary housing, and shipping, your costs may fall under €5,000. If you cover everything yourself, plan for €15,000–€25,000 minimum for a professional Western European relocation.
Factor 5: Benefits and Perks Valuation
What to measure: The monetary value of the full compensation package beyond base salary — and critically, what you are losing from your current package.
Why this matters: An overseas job may offer a higher salary but a worse benefits package. Health insurance that cost you nothing as an employee in Spain (covered by social security) may cost you €3,000–€6,000/year as a private subscriber in the US. Stock options in a European startup may be worth less than vested options at your current employer. Pension match at 8% is real money that base salary comparisons ignore.
Benefits to value explicitly:
| Benefit | How to Value It |
|---|---|
| Health insurance (employer-paid) | Cost of equivalent private plan in destination |
| Pension / 401k match | Actual employer contribution as % of salary |
| Stock options | Intrinsic value today + vesting cliff risk |
| Annual bonus | Expected value (probability × amount) |
| Education / tuition reimbursement | Actual cost of courses you would otherwise pay for |
| Remote work allowance | Value of home office stipend or coworking allowance |
| Extra vacation days | Value your time: extra 5 days × daily rate |
Scoring guide:
| Net change in total compensation (benefits included) | Score |
|---|---|
| Benefits add +20% or more vs current | +2 |
| Benefits add +5% to +19% | +1 |
| Benefits roughly equivalent | 0 |
| Benefits worth -5% to -19% less | -1 |
| Benefits worth -20% or more less | -2 |
Watch out for: Unvested stock options that you forfeit if you leave. Pension gaps if your new employer does not enroll you immediately. US employer health insurance that ends on your last day of employment, leaving you uninsured during your notice period.
Factor 6: Career Trajectory Premium
What to measure: The medium-term career and income impact of taking this role — promotion velocity, skill acquisition, network access, and re-entry risk if the move does not work out.
Why this matters: A financially neutral or slightly negative move can be worth taking if it accelerates your career by 3–5 years. Conversely, a financially positive move that moves you off your career track may cost more in the long run than the short-term salary gain.
Questions to score:
- Does this role open doors that your current role cannot? (access to a bigger market, more senior peers, exposure to different industries or technologies)
- Is the destination city a stronger job market for your profession? (London tech sector vs. equivalent role in a smaller market)
- What is the re-entry risk? If the role does not work out after 12 months, can you return to a comparable position at comparable pay in your home market?
- Does international experience have a measurable premium in your field? (Yes for finance, consulting, certain tech roles; less clear for others)
Scoring guide:
| Career trajectory impact | Score |
|---|---|
| Role clearly accelerates career; opens new markets/networks; international experience valued in your field | +2 |
| Modest positive trajectory; incremental step forward | +1 |
| Neutral — comparable to opportunities at home | 0 |
| Risk of career narrowing; role is more specialist than your current path; unclear exit options | -1 |
| Significant career risk; niche role in a declining market; limited re-entry options in home country | -2 |
Data point: A study by the OECD International Migration Outlook found that workers with international experience earn 10–15% more in their home country after returning, and are promoted faster on average. This premium is real — but it is not universal across all industries and roles.
Factor 7: Currency and Inflation Risk
What to measure: The financial risk created by earning in one currency, spending in another, or accepting a salary in a currency that is weaker or more volatile than your spending currency.
Why this matters: A 10% swing in exchange rates changes your real salary by 10% with no action taken. Over a 3-year period, this is not hypothetical — the EUR/USD rate has moved 20%+ in both directions in the last decade. If you earn in a currency you do not spend in, you carry exchange risk permanently.
Scenarios to evaluate:
Scenario A — Earn and spend in the same currency: Zero exchange risk. The salary you agree on is the salary you have. Score: 0 unless the currency itself is at risk of inflation or devaluation.
Scenario B — Earn in a major global currency (USD, EUR, GBP), spend in a weaker local currency: Usually positive. Your savings accrue in a stronger currency. Remote workers earning USD while living in Portugal or Mexico benefit from this structure.
Scenario C — Earn in a local currency, send money home: Your remittances fluctuate with the exchange rate. Transfer costs (typically 0.5–3% per transaction) are a real recurring cost. Wise and similar services reduce but do not eliminate this.
Scenario D — Earn in a weaker or more volatile currency: This is a financial risk. A role in Turkey paying 2 million TRY/year looked like a strong offer in 2021; by 2023, inflation had reduced the real value by 50%+ in USD terms. Do not accept this risk without a salary adjustment clause.
Scoring guide:
| Currency situation | Score |
|---|---|
| Earn in stronger currency than you spend; stable CPI differential | +2 |
| Earn and spend in same major stable currency | +1 |
| Earn in same currency as home country; standard CPI risk | 0 |
| Some mismatch but manageable; low volatility currency | -1 |
| Earn in weaker, higher-inflation, or volatile currency; no adjustment clause | -2 |
Mitigation: If you are offered a salary in a volatile currency, negotiate either USD/EUR denomination, a quarterly CPI adjustment clause, or a minimum salary floor in a stable currency equivalent.
Worked Example: Should Maria Take the Job in Amsterdam?
The setup: Maria is a software engineer based in Madrid. She currently earns 45,000 EUR gross (net approximately €30,000/year after IRPF and social security). She receives an offer for a role in Amsterdam at 75,000 EUR gross.
Let us score each factor.
Factor 1: Net Salary Difference
Madrid net on €45,000: ~€30,000/year (33% effective rate) Amsterdam net on €75,000: ~€47,000/year (37% effective rate, no 30% ruling assumed)
Net difference: +€17,000/year — a 57% increase in take-home pay.
Score: +2
Factor 2: Cost of Living Delta
| Category | Madrid | Amsterdam |
|---|---|---|
| Rent (1-bed center) | €1,300 | €1,800 |
| Groceries | €280 | €380 |
| Transport | €60 | €100 |
| Utilities + internet | €120 | €170 |
| Monthly total | €1,760 | €2,450 |
Cost of living increase: €690/month (€8,280/year) Net salary increase: €17,000/year Disposable income gain: €17,000 - €8,280 = +€8,720/year (+€727/month)
Score: +2 (over €600/month gain)
Factor 3: Tax Transition Costs
Spain does not have an exit tax for ordinary employees. Maria will file a partial-year Spanish return and a partial-year Dutch return. She needs a tax advisor: estimated cost €3,000.
Score: 0 (€2,000–€5,000 transition cost)
Factor 4: Relocation One-Time Costs
The employer covers temporary housing (2 months) and visa fees. Maria pays:
- Security deposit: €1,800
- Flights + shipping: €2,500
- Setup costs: €1,500
- Total: €5,800 (~2.4 months of net salary gain)
Score: 0 (3–6 months of gain consumed — borderline 0/-1, call it 0)
Factor 5: Benefits Valuation
Current Madrid role: private health insurance covered (€0 cost), 22 vacation days, no pension match.
Amsterdam offer: Dutch mandatory health insurance (employee pays ~€1,800/year), 25 vacation days (+3), employer pension match of 8% of gross = €6,000/year.
Net benefits change: -€1,800 (health) + €6,000 (pension) + €900 (vacation value at daily rate) = +€5,100/year
Score: +1 (benefits add ~11% vs current total comp)
Factor 6: Career Trajectory
Amsterdam has a larger tech sector than Madrid for Maria's stack (cloud infrastructure). The role is a senior individual contributor position at a scale-up — more complex environment than her current role. Exit options within the Netherlands and UK are good. Re-entry to Spain is possible but would likely require a step back.
Score: +1 (modest positive trajectory)
Factor 7: Currency Risk
Maria earns EUR in both Spain and the Netherlands. No currency mismatch. Dutch inflation has been high recently but is moderating.
Score: 0
Final Score
| Factor | Score |
|---|---|
| 1. Net salary difference | +2 |
| 2. Cost of living delta | +2 |
| 3. Tax transition costs | 0 |
| 4. Relocation one-time costs | 0 |
| 5. Benefits and perks | +1 |
| 6. Career trajectory | +1 |
| 7. Currency risk | 0 |
| Total | +6 |
Interpretation: Score of +6 = Strong financial case. Maria should take the role unless there is a compelling non-financial reason not to (family, lifestyle, personal preferences). The key risk is that tax transition and relocation costs reduce her Year 1 financial gain significantly — the full financial benefit materialises from Year 2 onward.

Red Flags That Mean NO
These conditions do not just reduce your score — they are warning signs that the offer may not be what it seems:
1. The employer will not cover visa costs. Visa processing for a work permit typically costs €1,000–€5,000. An employer unwilling to cover this is either poorly capitalized or signals that they do not genuinely value your relocation. In well-funded companies, visa support is standard.
2. The gross salary does not cover local living costs. If the offered gross salary nets out to less than 1.5× the local average rent, you will be financially constrained immediately. A gross salary of 40,000 EUR in Amsterdam nets about €27,000, or €2,250/month. With rent at €1,800+/month, you have €450/month for everything else.
3. The role requires you to forfeit unvested equity above 6 months of salary. Unvested stock or options you leave behind are a real cost. If your current vesting schedule has a large cliff approaching, that cost is material and should be explicitly discussed with the prospective employer.
4. No relocation package and no temporary housing provision. Moving internationally without any support means €10,000–€30,000 out of your own pocket before you receive your first paycheck. The absence of any relocation support often reflects the employer's assumption that this is a cheap hire, not a strategic one.
5. The salary is denominated in a currency with recent 10%+ annual inflation, with no adjustment clause. Without an adjustment clause, you bear the inflation risk of the destination country's currency. This is unacceptable in high-inflation economies.
When the Numbers Don't Tell the Full Story
A financial framework gives you a rational basis for comparison. It does not capture everything that matters.
Family and relationships are the most common reason people turn down financially superior offers. A +8 financial score does not override a partner's career, children's schooling, or aging parents who need support nearby. These factors are real and legitimate — the framework helps you understand what you are trading financially so you can make that trade consciously.
Healthcare for chronic conditions may be better managed at home where you know the system, speak the language, and have established care relationships. An offer that scores well financially can still be the wrong decision if your healthcare needs are complex.
Career risk tolerance varies. If losing the job after 6 months would put you in financial difficulty, a high-score offer that requires you to burn your savings on relocation may be too risky regardless of the upside. The framework assumes you can survive a scenario where it does not work out.
The lifestyle match. Some cities improve quality of life measurably — access to nature, climate, food culture, pace of life. Others are purely transactional environments. If Amsterdam's lifestyle does not appeal to Maria, a +6 financial score may not be enough to sustain the decision over 3–5 years.
Use the score as a floor, not a ceiling. If the financial score is negative or marginal, the burden of proof falls on non-financial factors. If the financial score is strongly positive, you are taking a financially sound step regardless of the other factors.
The calculator at ShouldIMove.co handles Factor 1 and Factor 2 automatically — net salary and disposable income comparison after cost of living. Use it as your starting point for the quantitative factors, then apply the full 7-factor framework to make the final call.
Frequently Asked Questions
How accurate is a 7-factor scoring system for something as complex as relocation?
The value of the framework is not precision — it is structure. Without a framework, people tend to anchor on one number (gross salary) and rationalize everything else. By forcing an explicit score on each factor, you surface trade-offs you might otherwise ignore. The scores are subjective by design; what matters is that you make the trade-offs visible.
My employer is offering "tax equalization" — how does that change the framework?
Tax equalization means the employer adjusts your gross salary so that your net pay is the same as if you were still in your home country. This effectively removes Factor 1 (salary difference) and improves Factor 3 (tax transition costs). Tax equalization is typically offered by large multinationals on long-term international assignments. If you have it, your framework score automatically gets a +2 on Factor 3 — but verify the exact mechanism, as some "equalization" clauses have gaps.
I'm comparing multiple job offers across different countries — how do I use this framework?
Run the framework independently for each offer, scoring against your current situation as the baseline. The offer with the highest total score is the strongest financial case. If two offers score similarly (within 2 points), the tie-breaker is non-financial.
Should I negotiate differently for overseas offers than domestic offers?
Yes. For overseas offers, always negotiate the full package: base salary, relocation support, visa costs, temporary housing, and tax equalization or a tax advisor budget. Domestic offers rarely include relocation costs; international offers should almost always include them. Use the cost of your move as a concrete anchor: "My estimated relocation costs are €15,000. I'd like to discuss including a relocation allowance in the package."
