Formula & calculation method
Swiss Banking Tragbarkeit Formula & Maximum Purchasing Power
Theoretical Costs = (Loan x 5%) + (Price x 1%) + (2nd Rank / 15 yrs) <= 33% of Gross Annual Income
Under standard 80% LTV financing (65% in 1st rank without mandatory amortization and 15% in 2nd rank amortized over 15 years), annual theoretical stress costs total exactly 6.0% of the property value (4.0% interest + 1.0% maintenance + 1.0% amortization). Therefore, your maximum affordable property price equals approximately 5.5 times your gross annual income, provided you have at least 20% down payment (with 10% in hard equity).
Step-by-step calculation example
With a gross annual income of 180,000 CHF: maximum allowed theoretical budget (33%) is 59,400 CHF/year. Divided by the 6.0% stress rate, the bank allows a maximum property price of 990,000 CHF with 198,000 CHF equity (at least 99,000 CHF in hard cash/pillar 3a).
Key insights to remember
Automatic Limiting Factor: Our engine instantly calculates whether your homebuying capacity is capped by your income (33% rule) or by your down payment.
Hard Equity Rule: By SBA regulation, at least half of the mandatory 20% down payment (10% of property value) must come from hard personal equity, not 2nd pillar pension withdrawals.
5% Stress Rate: Even when market mortgage rates are 1.5% to 2.0%, Swiss banks test your long-term solvency using a 5% baseline rate to cushion against future rate spikes.
How to interpret your results?
33% Affordability Ceiling & Stress Testing
If theoretical expenses represent 30% or less of gross income, your profile is considered comfortable. Between 30% and 33%, the application is acceptable but close to the regulatory limit. Above 33%, lenders require additional equity or deny financing.
Income vs Down Payment Tradeoff
A high salary without sufficient equity blocks loan approval (20% minimum rule). Conversely, extra equity reduces total borrowing into the 1st rank, lowering theoretical costs and expanding affordability.
Expert advice & guidance
💡 Expert advice: To optimize your Tragbarkeit without sacrificing retirement assets, pledging pillar 3a or 2nd pillar pension funds (collateral assignment without withdrawal) satisfies bank security requirements while preserving your tax deductions and full pension coverage.
Frequently asked questions
How much mortgage can I afford in Switzerland based on my income?
Swiss lenders apply the Tragbarkeit rule: total theoretical housing expenses (calculated at 5% stress interest + 1% maintenance + 2nd rank 15-year amortization) cannot exceed 33% of your gross annual household income. In practice, this corresponds to a maximum property price of approximately 5.5 times your annual gross salary, provided you have at least 20% down payment.
How does the Swiss mortgage affordability (Tragbarkeit) test work?
The bank sums three theoretical cost components: 1) Interest calculated at a 5% benchmark rate on the total loan; 2) Property maintenance and ancillary charges budgeted at a flat 1% of the property value; 3) Linear amortization of the 2nd mortgage tranche (between 65% and 80% LTV) over 15 years. If this sum exceeds 33% of gross income, the application is rejected.
How much 2nd pillar (LPP/BVG) pension can be used for a mortgage?
SBA self-regulation requires at least 10% of the property value to be funded from hard personal equity (savings, pillar 3a, or inheritances). You can only use 2nd pillar pension assets (through withdrawal or pledging) to fund up to 10% of the property value.
How is qualifying income calculated for a Swiss mortgage?
Lenders recognize 100% of proven base salary and 13th month payments. Variable bonuses are typically averaged over the last 3 years with a risk discount (e.g. 50% to 80%). Net recurring rental income is standardly recognized at 80%.
What can you do if your affordability ratio exceeds 33%?
If your ratio exceeds 33%, you can: 1) Increase your cash down payment to reduce total borrowing; 2) Add a solvent co-borrower (spouse or registered partner); 3) Pledge pension assets (pillar 3a or BVG) as collateral without withdrawing them; 4) Target a slightly lower property price.
