Updated on August 24, 2026 · Indicative methodology based on SBA, FINMA sources and Swiss banking practices · No credit commitment
Estimate your maximum Swiss mortgage, 1st and 2nd rank distribution, required down payment, and amortization schedule. Based on Swiss banking practices and ASB guidance. Results are indicative and not a credit decision.
How to use this calculator?
Enter the property purchase price and optional bank appraisal (banks use the lower-of-cost-or-market principle).
Specify your total down payment and the optional 2nd pillar LPP portion (at least 10% must be hard equity).
Enter gross annual household income, eligible rental income, and years remaining before retirement.
Input the actual interest rate quoted by your lender to calculate the estimated actual monthly payment.
Review your 1st and 2nd rank breakdown, 5% stress-test affordability ratio, amortization schedule, and recommendations.
Indicative model based on Swiss Bankers Association (SBA) self-regulation guidelines.
Step-by-step calculation example
For a 1,000,000 CHF home with 200,000 CHF down payment (including 50,000 CHF LPP) and 200,000 CHF gross income: Loan = 800,000 CHF (1st rank 650,000 CHF, 2nd rank 150,000 CHF amortized over 15 years, or 10,000 CHF/year). Annual theoretical expenses = 40,000 CHF (5% stress interest) + 10,000 CHF (1% maintenance) + 10,000 CHF (amortization) = 60,000 CHF/year. Affordability ratio is 30.0%, safely within the standard 33% guideline (comfortable banking tier).
Key insights to remember
Lower-of-Cost-or-Market Principle: Swiss banks use the lower value between agreed purchase price and independent bank appraisal.
Hard Equity Requirement: At least 10% of pledge value must originate from cash, savings, or 3rd pillar (excluding 2nd pillar LPP).
Indicative 1st Rank Threshold: This calculator uses an indicative 65% threshold for the 1st rank. Individual lender policies and borrower profiles may vary.
2nd Rank Amortization: The portion above 65% (up to 80%) must generally be amortized linearly over 15 years or before retirement age.
5% Theoretical Rate: Swiss banks typically apply a theoretical 5% interest rate in affordability calculations regardless of actual market quotes. Total theoretical costs (5% interest + 1% maintenance + amortization) should generally not exceed 33% of qualifying income.
How to interpret your results?
Affordability Ratio (Tragbarkeit)
If theoretical expenses stay at or below 33% of gross income, your mortgage application satisfies standard Swiss bank criteria. Between 30% and 33% is close to lending limits.
Hard Equity Requirement
At least half of your 20% down payment (10% of total property value) must come from cash or 3rd pillar savings rather than 2nd pillar (BVG/LPP) pension assets.
Expert advice & guidance
💡 Expert advice: An affordability ratio slightly above 33% or tight down payment is not an automatic rejection. Many Swiss lenders and pension funds structure customized solutions (2nd pillar pledging without withdrawal, extended amortization). Our partner mortgage specialists can help optimize your borrowing profile.
Frequently asked questions
How much down payment is required to buy property in Switzerland?
In Switzerland, Swiss Bankers Association (SBA) self-regulation guidelines generally require a minimum 20% down payment, with at least 10% from hard equity outside the 2nd pillar pension (LPP/BVG).
How to buy a home with only 10% cash down payment in Switzerland?
You can provide 10% in hard cash/3a equity and pledge your 2nd pillar LPP pension funds to cover the remaining 10% without withdrawing them in cash.
Can you have 2 mortgages in Switzerland (1st and 2nd rank)?
Yes, Swiss mortgages are traditionally split into two tranches: a 1st rank (covering up to 65% of pledge value with no mandatory amortization) and a 2nd rank (covering up to 80%, amortized within 15 years or by retirement).
Why do Swiss banks apply a 5% stress-test interest rate?
Swiss banks typically apply a theoretical 5% stress-test interest rate in affordability calculations to ensure borrowers can sustain mortgage payments even if interest rates rise in the future.
