What You Need to Think About Before Signing a Lease: Costs, Risks and Tips

Anyone driving a new car without having paid the purchase price has, in many cases, signed a lease, because the model offers predictable monthly payments without tying up a large amount of capital. What the brochures tend to leave out: what happens when there are more kilometres on the clock at return than originally agreed, or when the comprehensive insurance pays out less after a total loss than the outstanding lease balance? These questions should be answered before you sign.

What Is a Lease?

Leasing grants the right to use an object, often a vehicle or a machine, for an agreed term without transferring ownership. The lessor remains the owner; the lessee pays monthly instalments and either returns the object at the end of the term or takes it over at a pre-defined price.

With mileage leasing, a maximum annual distance is fixed when the contract is signed. Excess kilometres cost a defined surcharge, while unused kilometres are partially refunded. With residual-value leasing, a projected vehicle value at the end of the term is agreed, and the lessee bears the difference if the actual market value falls below it, which can lead to an unpredictable additional payment for vehicles with high depreciation.

The Most Important Contract Components

Lease agreements may look similar at first glance, but differ considerably in the details. A comparison based solely on the monthly payment can be misleading.

Lease Payment and Effective Annual Interest Rate (EALR)

The key figure for comparing offers is the effective annual interest rate (EALR), which must be disclosed for every leasing offer under the Consumer Credit Act and includes all cost components. An offer with a low monthly payment but a high EALR can end up being more expensive over the full term than a contract that costs slightly more per month.

A high down payment reduces the monthly instalment but does not improve your position in the event of damage, because comprehensive insurance only reimburses the current market value in cases of theft or total loss, and the absence of GAP cover turns the difference to the outstanding lease balance into a personal liability. For a detailed look at what happens after a total loss on a leased vehicle, see our dedicated guide.

Comprehensive Insurance and GAP Cover

Comprehensive insurance is mandatory in virtually all Swiss lease contracts because the vehicle legally belongs to the lessor. Costs vary considerably depending on the vehicle, deductible and provider.

GAP insurance covers the shortfall between the insured value of the vehicle and the outstanding lease balance, which can be substantial after one to two years of use. For expensive models and long contract terms, this cover should not be overlooked.

Mileage Clause and Excess Mileage Costs

Excess mileage charges may seem small per kilometre, but over a multi-year term with consistent overuse they quickly add up to several hundred francs. Choosing a more generous mileage allowance at the start of the contract is often the more economical option. Read more about mileage limits in leasing.

Risks and Cost Traps the Contract Does Not Highlight

The monthly payment always appears in bold in the offer, but what sits in the fine print often determines how expensive the contract actually turns out to be.

Early Termination

Exiting a lease early is possible but regularly costs significantly more than just the remaining payments, because the lessor factors in its calculated profit over the entire term. A contractual exit clause can help, but is rare and needs to be actively negotiated at the time of signing. If you find yourself in this situation, a lease takeover may be an alternative worth exploring.

ZEK Entry and Creditworthiness

Lease contracts in Switzerland are registered with the Central Credit Information Office (ZEK) and count as open consumer credit obligations. This can affect your creditworthiness for further financing, such as mortgages.

Tax Considerations for the Self-Employed and Businesses

For the self-employed and businesses, lease payments are deductible as operating expenses when the vehicle is used for business purposes. In cases of mixed use, only the proportional business share applies, and VAT treatment varies depending on the canton and legal form. For more detail, see our guide to car subscriptions for the self-employed as a flexible alternative.

Seven Things to Clarify Before Signing

1. Compare offers by the EALR, not by the monthly payment. Identical monthly amounts with different annual interest rates can mean significant cost differences over a long term.

2. Choose a slightly generous mileage allowance rather than a tight one. The additional cost of a higher package at signing is lower than the excess mileage charges at return.

3. Document the vehicle condition at handover thoroughly. Use time-stamped photos and a signed handover protocol. Verbal agreements tend to carry little weight at return.

4. Read the return conditions at the time of signing. Clarify what counts as normal wear and tear and what is considered a defect, so you do not end up paying for things that are part of regular use. Our guide to the 7 most expensive lease return mistakes covers this in more detail.

5. Compare the comprehensive insurance separately. Lessors typically recommend a partner insurer, which is not necessarily the most affordable option for your situation.

6. For expensive vehicles and long terms, check whether GAP insurance makes sense. The gap between the insured value and the outstanding balance can be substantial in the event of a claim.

7. Ask specifically about the exit conditions. Find out what an exit after 12 and after 24 months would cost. If a provider cannot give a clear answer to this question, that is already an answer in itself.

Frequently Asked Questions

What is the difference between mileage leasing and residual-value leasing?

With mileage leasing, a maximum annual distance is agreed, keeping costs predictable. With residual-value leasing, the final settlement depends on the actual market value and can, in the worst case, lead to a significant additional payment. For a deeper comparison, see our article on the advantages and disadvantages of leasing.

Can I terminate a lease early?

Early termination is possible but rarely comes cheap, because the lessor prices in its calculated profit over the entire term. The exact costs should therefore be recorded in writing before signing the contract.

Do I need comprehensive insurance for a leased car?

In Switzerland, nearly all leasing providers require comprehensive insurance because the vehicle legally remains with the lessor.

What is the EALR and why does it matter more than the monthly payment?

The effective annual interest rate (EALR) captures all costs of a lease and must be disclosed under Swiss consumer credit law. Two offers with the same monthly payment can differ significantly in their EALR, which becomes decisive over the full term.

Does a lease affect my creditworthiness?

Lease contracts are registered with the ZEK and count as open consumer credit obligations. This can influence your chances of obtaining further financing and should therefore be factored into your decision.

Conclusion: What Really Matters Before Signing a Lease

Leasing does not suit every life situation. For someone who wants to switch vehicles regularly and avoid tying up capital, it is a sensible option. For someone looking to build ownership over the long term, it tends to be more expensive than buying.

The most common cost traps arise from insufficient preparation: underestimated mileage, missing GAP cover, comprehensive insurance taken through the lessor rather than independently compared, and return conditions read only at the appointment itself.

When comparing offers, the EALR matters more than the monthly payment, and the clauses on excess mileage, return and early termination matter more than anything else, because that is precisely where the hidden costs arise. Anyone who clarifies these points before signing and compares at least three offers is in a significantly stronger position.
