Net to Gross Salary Calculator
Start from the take-home pay you actually need and work backwards to the gross salary you should be asking for — in Germany, the Netherlands and Ireland side by side.
Gross salary you need
Same take-home, three countries
| Country | Gross per year | Gross per month |
|---|
Useful when an offer arrives from abroad: the headline number means nothing until it is converted into the same take-home.
Single person, no dependents, standard employment contract, tax year 2026. Germany: §32a EStG tariff and 2026 social insurance rates. Netherlands: box 1 brackets and credits per Belastingdienst; private health premium excluded. Ireland: Budget 2026 bands, USC and PRSI Class A.

Rounded estimates from the same engine as the calculator. Notice the gap widening — that is progression at work.
Going the other way?
If you already know the gross, see the full breakdown and cost-of-living comparison instead.
Open Salary Calculator →Why you cannot just add the tax rate back
If you pay 35% of your salary in tax and social security, it is tempting to divide your target net by 0.65. That undershoots, often badly. The extra gross needed to deliver one more euro of net is taxed at your marginal rate — around 42% in Germany's upper progression zone, 49.5% in the Dutch top bracket, 40% plus USC and PRSI in Ireland — not at the average rate you are currently paying.
This calculator sidesteps the problem by solving the real tax formula backwards: it searches for the gross salary whose calculated net matches your target, to the cent.
Estimates are for comparison and negotiation, not payroll. Tax class, dependents, pension contributions, company benefits and regional rates all shift the real figure — confirm with your employer's payroll provider before signing anything.
Frequently asked questions
How do I calculate gross salary from net salary?
You cannot simply add the tax rate back, because tax is progressive: the extra gross needed is taxed at your top marginal rate, not your average one. This calculator solves the tax formula backwards until the resulting net matches the figure you entered.
What gross salary do I need for €3,000 net per month?
It depends heavily on the country — the quick-reference table above is generated by the same engine as the calculator, so enter your own target and read the figure straight off it rather than relying on a rule of thumb. Germany needs the highest gross of the three because social insurance is charged on top of income tax.
Why does the same net pay need a different gross in each country?
Germany levies heavy social insurance on top of income tax, the Netherlands folds national insurance into its first bracket and offsets it with large credits, and Ireland uses a low standard band with USC and PRSI on top. Identical take-home therefore corresponds to very different gross salaries.
Can I use this to negotiate a job offer?
Yes — that is what it is for. Decide what you need to live on, get the gross figure for each country, and negotiate against that number rather than against a percentage increase.
