Net to gross salary
Know the net salary and need the gross? Enter the required net pay and credits — the calculator grosses up the income and computes the gross salary needed under 2026 and 2025 legislation.
How to convert net salary to gross?
Converting net to gross is not simple multiplication — the gross salary is the net plus social insurance (7.1%), health insurance (4.5%) and advance income tax, from which tax credits and the child tax benefit are deducted. Because the tax depends on credits and the higher 23% rate applies to larger salaries, the calculator finds the gross iteratively so the resulting net matches your input.
It is handy for salary negotiations (“I want CZK 40,000 net”), budgeting and for employers estimating the total cost of work. For the opposite direction use the net salary calculator.

For guidance only. Due to rounding, several gross amounts can yield almost the same net — the tool returns the lowest matching gross.
