Night Shift Premium Calculator 2026

The premium for night work is 20% of the hourly rate derived from the statutory minimum wage. In 2026, with a minimum wage of about PLN 4,806 and 168 working hours, the hourly rate is about PLN 28.61, so the night premium per hour is about PLN 5.72. The amount changes each month with the number of hours to be worked.

Night time covers 8 hours between 9 p.m. and 7 a.m. The employer sets the specific night-time hours in the work regulations or the information on employment conditions (e.g. 10 p.m.–6 a.m.). An employee working in those hours is entitled to the night-work premium, regardless of whether they are a night worker.

Premium = 20% × (minimum wage ÷ number of working hours in the given month) for each hour worked at night. The working-hours norm changes monthly (e.g. 160, 168, 176 hours), so the per-hour premium differs between months. The total premium is the per-hour premium multiplied by the number of night hours.

No. The night-work premium is always calculated from the statutory minimum wage, not from the employee’s individual salary. This means an employee earning PLN 10,000 and one on the minimum wage receive the same night premium per hour — only the number of night hours worked differs.

Yes. For employees who permanently work at night outside the workplace the premium may be replaced by a lump sum. The amount should correspond to the expected extent of night work. A lump sum simplifies settlement but must be set fairly so as not to understate the premium due.

The night premium arising from the Labour Code is due to employees on an employment contract. Under a contract of mandate (umowa zlecenie) the pay terms, including any night-work premiums, are set by the civil-law contract itself. A contractor is, however, guaranteed a minimum hourly rate, which in 2026 is also indexed.

Yes. If night work is also overtime, the employee is entitled to both: the night-work premium (20% of the minimum rate) and the overtime premium (50% or 100% of pay). These are two separate entitlements and do not exclude each other.

The nominal working-time norm for a given month is calculated under the Labour Code rule: 40 hours × number of full weeks + 8 hours × number of remaining Monday–Friday days, minus public holidays. In practice this is most often 152–184 hours. The default 168 hours is an indicative value for a typical month.

Yes. The night-work premium is income from employment, so it is subject to ZUS contributions and the PIT income-tax advance on the same terms as other pay components. The amount shown in the calculator is the gross value of the premium, before contributions and tax are deducted.

The calculator gives an indicative night-premium amount for the parameters provided. The actual amount depends on the real working-hours norm in the given month and the current minimum wage (in 2026 the rate may be indexed during the year). For a precise result, enter the exact working-hours norm and the current minimum rate.
