What is mortgage amortisation?

Amortisation: repaying the borrowed capital

Amortisation refers to the process of gradually repaying the capital borrowed as part of a mortgage loan.

Unlike interest, which represents the cost of financing:

• amortisation directly reduces your outstanding debt,

• it decreases the amount of the loan over time.

Why amortise your mortgage?

Amortisation plays a central role in managing property financing.

It allows you to:

• reduce your level of debt,
• lower interest payments over the long term,
• adjust your financing structure over time.

It is therefore a key component of both financial security and wealth management.

The two main types of amortisation

In Switzerland, amortisation generally takes two main forms.

Direct amortisation

Direct amortisation consists of repaying part of the capital on a regular basis.

• the debt decreases over time,
• interest costs decrease accordingly.

This approach prioritises reducing the level of debt.

Indirect amortisation

Indirect amortisation consists of building up savings, typically via pillar 3a, to repay the loan at a later stage.

• the debt remains stable during the term,
• the accumulated savings are used for repayment.

This type of amortisation is often linked to pension or savings solutions.

The amortisation framework in Switzerland

Within mortgage financing, part of the loan must generally be amortised.

In practice:

• the portion of financing above a certain threshold must be repaid,
• repayment must occur within a defined period or before retirement.

This framework helps ensure a gradual reduction of debt over time.

The impact of amortisation on your financing

The choice of amortisation method directly affects:

• your level of debt,
• the amount of interest paid,
• your tax situation,
• and your cash flow management.

It is therefore a strategic lever in structuring your financing.

Amortisation and wealth strategy

Amortisation should not be considered in isolation.

It is part of a broader reflection that includes:

• your financial situation,
• your long-term objectives,
• your pension planning,
• and your tax considerations.

Two main approaches can be considered:

• prioritising debt reduction,
• or optimising the use of available financial resources.

Adapting your strategy over time

Amortisation is not fixed and may evolve depending on your situation.

It may be relevant to:

• adjust the repayment pace,
• revisit the financing structure,
• reassess your financial priorities.

A dynamic approach helps maintain a balanced strategy over time.
