Hello,

I have a friend that is currently working 100%.

From 4750.00 they pay 650.5 in social deductions (ahv, accident insurance etc).

He is looking at moving to an 80% job so that he can undertake education in a new sector at the side.

Is it true that the social deductions actually go up in percentage?

I.e. When we looked at projected salary with a company, if he earned 5200.00, which is 4160.00 @ 80%, it worked out as him paying 550ish per month in social deductions.

Is that correct, or do social deductions scale down in some way for part time workers?

Some deductions are in % (like AHV/AVS, OASI, UI, etc.), some might be fixes (deductions for insurance from your employer, for example. Those probably won't change).

If that's the case then the calculations were right and he can't afford to take the 80% job despite the much higher base pay. Hmm.

It's difficult to give an answer without more details regarding his/her deductions (except from the obvious % ones)

Even though the education is in a different sector, an employer may still support that increase in knowledge and competence. It won't hurt to ask the potential employer how they see this. Ambition alone is a character trait companies look out for, and demonstrating it by walking an extra mile proves one's worth.

Proportionally, social deductions are a fixed percentage up to 4160, and then at a higher rate above that. There is no loading at lower pay!
Current rates are: 10.6% AHV/IV/EO, 2.2% ALV, higher ALV 1% over 12,350 a month. For your friend then, social deductions are 12.8%
4750 -> 608
5200 -> 665.60
4160 -> 532.50

I've no idea where the extra 20 francs deduction is coming from. He should ask.

4750 is what he's paid now, because he works at InterDiscount and they pay people like shit.

5200 is what he's asking for at the new place.

Agency that's also looking for him said he should ask for 5500 based on his education and experience.

650.5 is straight from his salary sheet.

550 is using the same deductions as on his salary sheet, just based on 80% of 5200.

I don't have the numbers to hand, only the outcomes. I can get them in a couple of days, I think.

Careful when comparing salaries at different companies.

Some deductions might not be the same at all (for instance, one employer might have a higher second pillar deduction, or better/worse insurance, resulting in higher or lower deductions).

When I switched jobs, my deductions ended up being way more. It all went into a "better" second pillar, but still

I've checked over my own payroll that I've been running for a several years, and possibly NBU (non-occupational accident insurance) has been set as a fixed amount by the employer. I can't think of anything else that may not be a set percentage.

Also, different Cantons have different deductions (for instance, in Canton Vaud you get deductions for PG Famille on top of the usual mandatory deductions)
