- The special rate uses an estimated annual wage here. For a more accurate withholding, copy the special-rate annual wage from your payslip.

How this tool works
Calculating part-time salary starts by identifying the share of a full-time contract you work. This is the part-time factor. With a 40-hour full-time norm, 32 hours equals exactly 80%. Under a 36-hour norm, the same 32 hours is about 88.89%. This free part-time salary calculator uses the norm from your collective agreement or employment contract to scale gross pay, then calculates the net result.
The page starts with an amount belonging to a full-time contract. Check this first: a vacancy may already quote pay for the offered part-time hours. In that case select that the amount belongs to your actual hours. The calculator does not reduce an actual-hours amount a second time. The full-time equivalent remains visible in the output as a comparison basis.
There are three ways to enter your working pattern. Supply weekly hours directly, choose a percentage of full-time or use working days per week. In days mode, one day means one fifth of the chosen full-time norm. Four days therefore means 80%, even when full-time is 36 hours. If you work four unequal or longer days, entering hours is more accurate than counting days.
Net salary does not scale by the same factor as gross salary. Tax credits and tax rates depend on pay. The calculator therefore determines the new gross salary first and applies the 2026 table afterwards. If you provide a net full-time amount, it first finds corresponding gross pay. Only then does it apply the part-time percentage and recalculate take-home pay.
Holiday allowance, a thirteenth month and a percentage year-end payment follow the chosen salary basis. A fixed bonus is the amount you enter for your own situation; it is not silently reduced proportionally. Check the contract if fixed bonuses change with working hours. The comparison underneath displays a current schedule alongside a new offer, including net annual income with all entered extras.
Use the output to prepare a conversation about working more or fewer hours. Pension, travel reimbursements, childcare benefits and other income-dependent schemes are not automatic parts of this conversion. A collective agreement may also have different arrangements for leave, overtime or fixed payments. Keep the supporting contract details with the free PDF. For a more detailed payroll breakdown, transfer the calculated amount to the sample payslip.
Full-time to part-time salary
Part-time gross = full-time gross × actual hours ÷ full-time hours
First identify whether offered pay is full-time. Choose actual hours when the amount already covers your contract.
Part-time factor as a percentage or days
Four days out of five = 80%
For unequal working days, enter hours. In days mode a day always represents one fifth of the full-time norm.
Limits of this tool
Part-time net salary is recalculated
The output excludes changes in benefits, pension or travel costs, which can affect the household difference.
Common questions
What percentage is working 32 hours?
It is 80% of 40 hours, 84.21% of 38 hours and 88.89% of 36 hours.
Does working 80% give me 80% net salary?
Not automatically. Gross pay scales, then payroll withholding and tax credits change according to the new salary.
Does working four days always mean 32 hours?
No. In this days mode it means 80% of the full-time norm. With full-time at 36 hours that is 28.8 hours.
Should I reduce an offer already quoted for part-time hours?
No. Select that the amount covers actual hours; otherwise it would be reduced twice.
Does holiday allowance change with part-time work?
In this model it follows 8% of calculated basic pay. Check any different collective-agreement or contract terms.
