Edit: I was wrong. I'm comparing monthly cost and yearly income.

I think your math is wrong. 4,000 CHF / 100,000 CHF = 4%

I'm gonna go on a limb and say the 2500-4000 CHF was per month which would be 30,000-48,000 per year :)

I'm pretty sure the 4000 CHF is monthly :)

Oops. My bad.

4000 * 12 months = 48000 CHF
