💰 Salary Calculator
What it does: Gross → Net with all Swiss deductions (AHV, ALV, BVG, NBUV) automatically calculated.
Why useful: Complex Swiss social contributions are often opaque – this calculator shows immediately what remains net.
⏰ Part-Time Calculator
What it does: Shows hidden costs of part-time work (pension gap, BVG gap).
Why useful: Many underestimate the long-term effect: 80% part-time = often >20% pension loss!
🥩 CO2 Calculator (Meat)
What it does: Climate impact of your meat consumption (CO2 equivalents per year).
Why useful: Concrete numbers instead of "a lot" or "a little" – helps with conscious decisions.
🏡 Mortgage Calculator
What it does: Affordability according to Swiss bank standards (5% calculation interest, max. 1/3 income).
Why useful: Shows realistic maximum purchase price – before you fall in love with a house you can't afford.
🚗 Fine Calculator
What it does: Speeding → fine + possible license suspension.
Why useful: Swiss traffic fines are not trivial (from 25 km/h over = criminal proceedings!).

Notes / Limitations
⚠️ Switzerland-specific: All calculators based on Swiss laws, cantons, tariffs.
⚠️ No storage: Privacy first = no account, no history. Each calculation is ephemeral.
⚠️ Guidance, not legal claim: For complex cases (e.g., salary negotiation, mortgage application), calculators provide guidance – final decisions rest with employer/bank/court.
Background
Developed by Roger (founder of roger.tips) with expertise in legal tech. Goal: Transparency for Swiss everyday life – salary, taxes, housing, lifestyle.

💡 CO2 Calculator: Share results via WhatsApp (button available) – often surprising for friends.
💡 Mortgage Calculator: Use the 5% calculation interest (bank standard) – not the current low interest rate (otherwise unrealistic expectations).
