Gross vs net: the gap that surprises everyone
The salary you negotiate is gross: the full annual figure before anything is taken out. The salary you live on is net, the take-home pay that survives income tax and the compulsory contributions that fund pensions, healthcare, and unemployment insurance. The gap between the two is rarely small, and it is wildly different from country to country. A 120,000 gross salary keeps a very different share of itself in Austin, in London, and in Berlin, because each jurisdiction stacks its taxes and contributions differently. The point of this tool is to make that gap visible before you sign, relocate, or compare two offers, so you are reasoning about money you can actually spend rather than a headline that flatters one country over another.
Income tax in almost every country is progressive, which means it is applied in slices. The first band of your income is taxed lightly or not at all thanks to a personal allowance or tax-free threshold; each higher band is taxed at a steeper marginal rate. This is why your effective rate, the total tax as a share of gross, is always lower than the top marginal rate you hit. The calculator works the bands from the bottom up exactly as the tax authority does, so the effective rate it reports is the honest blended figure, not the scary headline number at the top of the table.
The two layers: income tax and social contributions
Most people focus on income tax and forget the second layer, which often bites harder at middle incomes. Mandatory social contributions, Social Security and Medicare in the US, National Insurance in the UK, the social-insurance package in Germany, pension and health levies across the Nordics, are usually charged as a flat percentage of earnings, often up to a ceiling. Because they are flat rather than progressive, they take a proportionally larger bite from a mid-level salary than from a very high one, which is the opposite of how income tax behaves. The take-home bar in the result separates these two layers so you can see whether tax or contributions is the bigger drag on your particular salary in your particular city.
Some countries fold almost everything into a single income-tax figure, while others split it across several named levies. The model normalises all of that into three buckets, income tax, social contributions, and any state, provincial, or local tax, so the comparison across cities is apples to apples even when the underlying systems look nothing alike. A flat US state add-on, a Canadian provincial rate, a Japanese inhabitant tax, and a Swiss cantonal blend all land in the same regional bucket.
Using take-home to compare cities and offers
Take-home pay is the right unit for a relocation decision, but it is only half the story: a higher net salary in an expensive city can buy less than a lower net salary somewhere cheap. The honest move is to pair this calculator with cost of living. Work out your net monthly take-home here, then check what that buys against local rent and essentials. We build that second half directly into our city salary pages, and our cost-of-living adjuster tells you what a given salary in one city is worth in another once both tax and prices are accounted for. For an actual job offer with equity and bonus on top of base, the offer evaluator places the whole package on the market distribution so you know whether the gross is even competitive before you start worrying about the net.
One practical tip when negotiating across borders: always convert to your own currency at the mid-market rate, not the rate your bank quotes, and always compare net to net. A recruiter quoting a gross figure in a low-tax country can make an offer sound far stronger than a higher gross in a high-tax one. Running both through this calculator strips out the spin and leaves you with the only number that matters, what you actually keep.
Frequently asked questions
- What does take-home pay actually mean?
- Take-home pay, also called net pay, is what reaches your bank account after the deductions that come straight out of a paycheck: income tax and mandatory social contributions such as Social Security and Medicare in the US, National Insurance in the UK, or pension and health insurance in much of Europe. It is the number that matters for budgeting, because it is what you can actually spend, not the headline gross figure on your offer letter.
- Why is my take-home so much lower than my gross salary?
- Two layers stack up. First, progressive income tax: only the portion of income in each band is taxed at that band's rate, but at a high salary the top slices are taxed heavily. Second, social contributions, which are often a flat percentage with their own ceilings. In high-tax European countries the combined effect can take 40 to 50 percent of a high gross; in the US or Singapore it is usually milder. The calculator shows the split so you can see which layer is doing the work.
- Does this account for my state, pension, or student loan?
- It applies a flat effective state or provincial rate where that varies (for example California or Ontario), and it uses the standard single-filer allowance for the country. It does not model voluntary pension salary sacrifice, employer pension matching, student-loan repayments, marriage or dependant allowances, or one-off tax credits, all of which change real take-home. Treat the result as a clean baseline you can adjust for your own circumstances.
- How accurate are the tax figures?
- The bands and contribution rates are the published 2025 and 2026 statutory schedules from each country's tax authority, named on the result. They are accurate for a typical single filer with standard deductions. They are deliberately a transparent national-average model rather than a full payroll engine, so your actual payslip will differ once your specific allowances and elections are applied.
- Is this tax advice?
- No. It is a reference estimate to help you understand roughly how a gross salary translates into spendable income across cities. It is not tax advice, not a guarantee, and not a substitute for payroll or a qualified accountant. Verify any number that drives a real financial decision.
