Gross vs net salary: what is actually deducted

Almost every job advert quotes a gross salary— the big number before anything is taken out. What you live on is your net pay, or take-home: what is left after the deductions. The difference between the two is the single most important thing to understand about your pay, and it is bigger than most people expect.

What gross actually is

Gross salary is the total your employer agrees to pay you before any tax or contribution. It is the headline figure on your contract and in job listings because it is the same for everyone — it does not depend on your personal circumstances. The moment deductions start, though, two people on the same gross can take home quite different amounts.

The deduction stack

Net pay is gross minus a stack of deductions. The exact stack varies by country, but it almost always includes:

• Income tax — usually progressive, so higher earners lose a larger share.
• Social contributions— National Insurance in the UK, FICA in the US, cotisations sociales in France, Sozialversicherung in Germany, Seguridad Social in Spain.
• Other payroll items— pension contributions, student-loan repayments, and sometimes union dues or insurance, depending on your situation.

The size of this wedge — economists call it the tax wedge— ranges from modest to very large depending on where you live.

Why the gap differs so much by country

In a low-deduction setting, take-home might be 75–80% of gross; in a high-contribution country like France or Germany it can be closer to 60–65%. That does not automatically make one better than another — a bigger wedge often funds healthcare, pensions and unemployment cover that you would otherwise buy privately. It does mean a gross salary in one country tells you very little about take-home in another.

Always convert to net

Whenever you compare offers, plan a budget, or weigh a move abroad, convert gross to net first. That is exactly what mytakehomepay.app is for: pick your country — UK, US, Germany, France or Spain— type in a gross figure, and see the real take-home with the deductions broken out.
