HAVE MY FILE REVIEWED

This calculation applies the usual criteria of Swiss banks and insurers. It is neither an offer nor a promise of financing: only the lender decides, after a full review of your file.

Which rules is this calculation based on?

In Switzerland, approval does not depend on the current rate but on two cumulative conditions applied by almost every lender.

20%

OF EQUITY

Twenty per cent of the purchase price must come from your own resources. At least half of that, meaning 10% of the price, must come from outside your pension fund.

33%

OF THEORETICAL COSTS

Calculated costs must not exceed one third of gross income. They combine theoretical interest, amortisation and maintenance costs.

5%

THEORETICAL RATE

The rate used is deliberately higher than the actual market rate, to check that the financing would remain affordable if rates rose sharply.

Amortisation

The debt must be reduced to two thirds of the property value within the usual fifteen years. The calculation therefore spreads this reduction over that period and includes it in the annual costs, even though repayment can then be arranged directly or indirectly.

Maintenance costs

An annual flat rate of one per cent of the property value covers upkeep, renovation and condominium charges. This amount is theoretical: it appears in the feasibility calculation even if your actual spending varies from year to year.

What the calculation does not tell you

A favourable result does not guarantee approval, and a tight result does not mean the project is impossible. Several factors are assessed case by case.

HAVE MY SITUATION CHECKED

THE NATURE OF THE INCOME

A variable bonus, self-employed income or a recent contract are not treated the same way by every lender. Some count only a three-year average, others disregard the variable part entirely.

EXISTING COMMITMENTS

Leasing, consumer credit, maintenance payments or the financing of a property you already own reduce available capacity and must be declared from the outset.

THE LENDER’S VALUATION

Financing is based on the value set by the lender, not on the seller’s asking price. Any gap between the two can only be bridged with additional equity.

SECOND PILLAR CONSEQUENCES

Withdrawing pension assets reduces your retirement benefits and often your death and disability cover. Pledging is sometimes a more favourable alternative.

Frequently asked questions about purchase capacity

The answers below cover the points our clients raise most often before submitting an application.

Why use a 5% rate when actual rates are lower?

expand_more

The theoretical rate tests the resilience of the financing over time rather than reflecting today’s cost. A mortgage is renewed several times over thirty years: the lender checks that you would stay afloat if rates returned to a high level. Your actual monthly payments will therefore be well below the theoretical costs shown.

Can I finance a purchase with only 10% equity?

expand_more

No. Twenty per cent of the price is still required, but half of it may come from your pension fund. The remaining 10% must consist of savings, securities, a gift or a pillar 3a. That is precisely the limit this calculator applies when you enter the share coming from the second pillar.

Are theoretical costs calculated on gross or net income?

expand_more

On gross annual household income, before tax and social security contributions. For a couple, both incomes are added together, provided both people are co-borrowers and jointly liable for the loan.

What happens if my costs exceed one third of my income?

expand_more

The application is not automatically refused, but it falls outside the standard framework and requires justification: higher equity, substantial assets, documented income growth or additional guarantees. Lenders treat these situations differently, which makes comparison all the more useful.

Does the result apply to an investment property?

expand_more

No. A rental building is assessed on yield, vacancy rate and the condition of the property, with often higher equity requirements. This calculator covers owner-occupied housing only.
