Why the 1/3 rule matters practically
It's not just advice: rental applications are routinely rejected when rent exceeds ~33% of gross household income. For a CHF 2,400 apartment you'll typically need CHF 7,200+ gross household income to be considered.
Total housing cost, not just rent
Add ancillary costs (often CHF 150–350), electricity, Serafe, contents/liability insurance and – frequently forgotten – the rental deposit of up to three months' rent that gets locked away at move-in.
Stress-test your number
Model your budget with the new rent before applying – if saving drops to zero on paper, it will in reality too.
