Reach your desired net: This is how the backward calculation works
Many employees know their target net (e.g., from salary negotiations), but do not know which gross amount they must demand in the contract. Since income tax increases progressively and social security contributions vary, the backward calculation is complex.
Our Net-to-Gross Calculator 2026 solves this problem for you. It simulates hundreds of salary statements in milliseconds to find the exact gross value for your individual details.
Advantages of Backward Calculation
- ✅ Salary Negotiation: Know exactly what you need to demand.
- ✅ Financial Planning: Calculate which gross is necessary for your fixed costs.
- ✅ Precise: Takes into account all social security contributions 2026.
Important Factors
The result depends heavily on your tax class and the additional contribution of your health insurance. The federal state also plays a role because of church tax.
Example: 2,500 Euro Net
To reach approx. 2,500 Euro Net in the year 2026 as a single employee (Tax Class 1, no children, NRW), a gross salary of about 3,950 Euro is required. About 650 Euro income tax and 800 Euro social security contributions are deducted from this.

How do you calculate gross from net?▲
Since the German tax system is progressive, there is no simple formula. Our Net-to-Gross Calculator uses an iterative procedure (binary search) to calculate exactly to the cent which gross salary is necessary to achieve your desired net.
Why do I need more gross for the same net?▲
Depending on your tax class and social security contributions (HI, CI, PI, UI), approx. 30% to 45% is deducted from the gross. So if you want 2,500€ Net, you often have to calculate with 3,800€ to 4,500€ Gross.
Which tax class is best for high net?▲
Tax Class 3 offers the lowest monthly deductions for married couples and thus the highest net – however, the partner must then expect higher deductions in Tax Class 5.
