Calculate your salary if you work fewer hours

I don't know if this helps you, but in my case, I went from 5 days to 3 days because it was more tax-efficient for me. So it's not just about dividing your salary by the number of days. Roughly speaking, I earned around €1500 with 5 days of work (full-time) and €1000 with 3 days.

Your salary is indeed dependent on several factors. Divide your gross salary by 40 hours and then multiply by the number of hours you're going to work. That's the gross salary you'll earn. But what you have left net really varies. You pay more employee costs for one number of hours than for another.

I don't know if you own a house, but usually the mortgage interest deduction is also in the name of the person who earns the most (it's most beneficial).

There are various online programs that can help you with this calculation. Google 'from gross to net salary' and you'll find quite a few. Make sure to choose one where you actually have to fill in some information, those are the most accurate, of course Good luck!

P.S. I eventually also went from 32 to 24 hours and it saved me around 200 euros net. But I now need to arrange one less day of childcare, so in that sense it's really more beneficial for us. Plus, I also wanted to be partly at home with my child, so it being a bit of a downside financially is also secondary

I went from 32 hours to 16 hours.
That saves about 300 to 400 per month.
I work in healthcare, so I'm managing with 3 days of daycare per month now.
So yes, it saves not only money but also the hassle of commuting back and forth.

Hi,

You can request a 'pro forma' from the HR department of your workplace. It's like a payslip that clearly shows the new situation (e.g., 24 hours).

Good luck!
