Salary vs cost of living
How to compare pay across cities when rents and prices differ — and where simplified COL indexes help or mislead.
Nominal pay is not purchasing power
Job posts quote salaries in local currency. Your lifestyle is priced in rent, groceries, transport, and taxes. Comparing Dublin to Lisbon or Austin to Warsaw on headline pay alone is how people overestimate a raise.
Pay by Role shows a cost-of-living-adjusted salary that rescales nominal pay using a city COL index (100 ≈ US baseline). Use it to ask: “Is this raise real after prices?” — not as a precise budget.
COL-adjusted pay answers a relative question — how this salary stacks up against a common price baseline — not “what I will spend next month.” Your basket (children, car, dining out, school fees) will diverge from any index.
Rent as a reality check
Housing often dominates city differences. We model a modest one-bedroom rent from a US baseline scaled by the local COL index. That is a sketch, not a listing — neighbourhood, flatmates, and commute can swing costs by 30% or more.
A useful personal check: estimate monthly take-home, subtract realistic rent for the neighbourhoods you would actually live in, and see what remains for everything else. If rent exceeds ~30–40% of take-home, the “higher” city may not feel higher.
If you already know your rent or have a shortlist of neighbourhoods, replace our modeled rent with those numbers. Keep the salary and tax estimates from this site, but let housing reflect your actual shortlist — that hybrid check beats trusting any single index.
Taxes and benefits change the math
Two countries with similar gross medians can diverge sharply after income tax and social contributions. Our tax estimates are simplified national models — they exclude many payroll taxes and local levies — so treat them as directional.
Employer benefits (healthcare, pension match, equity, parental leave) can be worth thousands per year. Fold them into the comparison when you can.
A practical rule: compare cash on a take-home basis first, then add a rough annual value for benefits you would otherwise buy yourself (health insurance premiums, retirement match, transit). Ignore perks you would not use; counting every snack stipend as cash inflates weak offers.
A practical comparison workflow
1) Fix the role and seniority. 2) Compare medians in a common display currency. 3) Check COL-adjusted pay and modeled rent share. 4) Run take-home for each country. 5) Adjust for benefits and lifestyle you will not compromise on (schools, family, visa).
The cost-of-living calculator on this site is built for that workflow — prefill it from any salary page.
When the two cities still look close after that workflow, decide on non-money factors explicitly: commute, visa stability, partner’s job market, and whether you expect to stay five years. COL math settles the cash question; it does not settle whether the move is worth it.
