Declining-balance depreciation: How to manage profit and taxes via the depreciation pattern

What is declining-balance depreciation?

Declining-balance depreciation is a method in which an asset is depreciated each year using a fixed percentage applied to the remaining net book value. This results in higher depreciation amounts in the first years, which continuously decrease over time.

It is one of the scheduled depreciation methods and is used to systematically reflect the consumption of an asset’s value over its useful life. The distinctive feature lies in the calculation logic: depreciation is not based on the original acquisition cost, but on the current net book value in each period.

This clearly distinguishes declining-balance depreciation from methods that work with constant annual amounts. As a result, the depreciation pattern over the useful life is uneven.

The next step is to understand in detail how the calculation works and what effects arise from it.

When is declining-balance depreciation appropriate?

Declining-balance depreciation is particularly appropriate when an asset delivers the greatest economic benefit at the beginning of its use or quickly loses value. In such cases, it reflects the actual value pattern better than straight-line depreciation.

For companies, the question is not which method is “correct”, but which best reflects the real use of an asset. Declining-balance depreciation is especially suitable where usage and loss of value are concentrated in time.

Typical practical use cases are:

• Investments in machinery with high initial capacity utilisation
• Acquisition of IT systems with short innovation cycles
• Vehicles or equipment with rapid loss of value
• Growth phases in which new assets are used intensively from day one

This allows value consumption to be depicted more closely in line with actual usage. This increases the informative value of the figures and creates a solid basis for financial decisions.

The method is less suitable for assets with a uniform benefit over their entire life. In such cases, straight-line depreciation often leads to a clearer representation of economic reality.

The method should therefore always be chosen based on the specific usage profile of the respective asset.

In practice, we often see that the depreciation method is chosen out of habit. What really matters, however, is whether it matches the actual usage curves of the assets. Only then do the figures provide a reliable basis for decisions,” explains fiduciary expert Curd Fasching.

How does declining-balance depreciation work?

Declining-balance depreciation is calculated by applying a fixed percentage to an asset’s net book value in each period. As a result, the tax base decreases every year, which automatically leads to declining depreciation amounts.

In practice, this means: the higher the initial book value, the higher the depreciation charge. With every year, the book value is reduced – and thus the depreciation amount as well.

A typical example from a Swiss SME:

A manufacturing company invests in a new machine for CHF 100'000. Due to intensive use in the first years, the company opts for declining-balance depreciation at a rate of 30%.

The table shows how book value and depreciation amount decrease in parallel year after year.

For practical use it is crucial that the selected rate is based on the same logic across the individual years and can be clearly followed.

What types of depreciation exist besides declining-balance depreciation?

In addition to declining-balance depreciation, straight-line depreciation and impairment (unscheduled depreciation) are mainly used in practice. The choice of method depends on how an asset’s value develops over time and how it is used in the company.

A compact comparison makes classification easier:

The table shows that in practice there are clear use cases. While straight-line depreciation provides stability, the declining-balance method better reflects dynamic value patterns. Impairment complements both methods in the case of extraordinary developments.

What is straight-line depreciation?

With straight-line depreciation, an asset is depreciated evenly over its useful life. The annual amount remains constant because it is based on the original acquisition cost.

This method is particularly suitable for assets with uniform benefits and stable value development.

What is progressive depreciation?

Progressive depreciation leads to increasing depreciation amounts over time. In practice, however, it is hardly ever used.

For most companies in Switzerland, it is therefore of little relevance.

What is an impairment (unscheduled depreciation)?

An impairment exists when an asset unexpectedly and permanently loses value. In this case, the book value is adjusted once.

This form of depreciation is applied independently of the chosen method and is used on a case-by-case basis.

What tax requirements apply in Switzerland?

In Switzerland, depreciation is tax-deductible if it is business related. This means that the chosen depreciation must be economically justifiable and must not primarily serve tax optimisation.

For companies, it is crucial that the depreciation method, rate and application are documented consistently and plausibly. The tax authorities examine not only the amount of depreciation, but also its justification in the context of the actual use of the asset.

A key point is the distinction between commercial law and tax law. While the Swiss Code of Obligations (OR) allows for a conservative valuation, tax practice is more oriented towards standardised guidelines and empirical values. The Federal Tax Administration (ESTV) publishes guidelines with reference depreciation rates by asset category. In practice, these serve as the main orientation for tax-accepted depreciation.

In practice, this means: the choice of depreciation rate is not free. Companies follow the ESTV reference rates and deviate from them only if there is a well-founded economic justification.

This results in three key requirements:

• Depreciation must be economically justified (usage, loss of value, industry)
• It must be applied consistently over time
• It must be documented in a transparent and verifiable way

It should be noted that the concrete design of depreciation in Switzerland partly depends on cantonal practice. In particular, there may be differences in the level of depreciation rates.

For CFOs and fiduciaries, this means: declining-balance depreciation is generally permitted, but must always be aligned with tax practice and be well justified.

Tax recognition depends less on the method itself and more on whether it is justifiably explained and applied consistently. This is precisely where most discussions with the authorities arise in practice,” says Curd Fasching.

How do depreciation charges affect cash flow, liquidity and ROI?

Depreciation is non-cash, but indirectly affects key financial metrics such as cash flow, liquidity and return on investment (ROI). The effect mainly arises through changes in taxable profit.

If, for example, higher depreciation is recognised, reported profit is reduced. This lowers the tax burden, leading to higher operating cash flow and more available liquidity – particularly in the early years under declining-balance depreciation.

For financial management, the effects can be summarised as follows:

• Cash flow: Higher depreciation reduces tax payments and thus increases operating cash flow
• Liquidity: Less tax outflow means more funds available in the short term
• ROI: Reported profit directly influences return metrics and their trend over time

Especially compared with straight-line depreciation, the declining-balance method shifts these effects more strongly into the early phase of an investment. This can play an important role, particularly for growth-oriented companies or capital-intensive investments.

For CFOs and finance managers this means: depreciation is not just an accounting tool, but an active lever for managing financial flexibility, investment capacity and performance metrics.

In practice, this effect is particularly evident in reporting: Tools such as Analise Franci help to present different depreciation patterns transparently and make their impact on cash flow and key figures directly visible.

When should you switch from declining-balance to straight-line depreciation?

Switching from declining-balance to straight-line depreciation makes sense as soon as the straight-line method results in a higher annual depreciation amount. This allows the remaining value of an asset to be spread more efficiently over the residual useful life.

The background is the logic of declining-balance depreciation: over time, depreciation amounts decrease because they are based on an ever smaller net book value. From a certain point on, straight-line depreciation is therefore economically more advantageous.

In practice, this means:

• At the beginning, declining-balance depreciation is usually higher
• Over time, the depreciation amount decreases
• At some point, the straight-line depreciation amount exceeds this figure

From this point on, a numerical check of a switch is generally particularly worthwhile.

A brief comparison illustrates the principle:

• Declining-balance: decreasing amounts based on net book value
• Straight-line: constant amount based on remaining book value

This gives companies clear optimisation potential: switching can prevent assets from being depreciated only minimally in later years.

Proper implementation is important:

• The switch should be justifiably explained
• The calculation must be documented correctly
• The chosen method must be applied consistently going forward

In practice, this potential is often not used, even though it can be implemented without great effort.

What errors commonly occur in connection with depreciation?

In practice, depreciation errors usually do not arise from the calculation itself, but from incorrect assumptions, lack of coordination or insufficient documentation. Especially with declining-balance depreciation, such errors can have direct tax consequences.

A common error is selecting an inappropriate depreciation rate. If it is set too high and is not economically justified, the tax authorities may correct it. Conversely, a rate that is too low means that potential benefits are not fully used.

Equally problematic is a lack of consistency in application. If the method or rate is changed without a clear justification, transparency suffers – particularly in the context of audits or tax inspections.

Typical errors in practice include:

• Depreciation rates without a clear economic basis
• lack of alignment between accounting and tax practice
• inconsistent application of the chosen method
• insufficient documentation of decisions and calculations

Another critical point is the weak link to the fixed-asset register. If depreciation is not properly aligned with the recorded assets, inconsistencies in financial reporting arise.

For companies this means: depreciation should not be viewed in isolation, but as part of a structured process. Clear guidelines, clean documentation and regular reviews help to avoid errors and ensure tax certainty.

How to implement an effective depreciation strategy in your company

An effective depreciation strategy does not emerge by chance; it is based on clear rules, coordinated processes and consistent application across all assets. The goal is to link economic reality, tax requirements and financial steering.

In practice, this means that depreciation is not decided in isolation for each asset, but defined systematically as part of financial and corporate management.

A structured approach in particular includes the following elements:

• Clear definition of the depreciation method for each asset category (e.g. machinery, IT, vehicles)
• Definition of comprehensible depreciation rates based on usage and experience
• Regular review of the depreciation logic for new investments, changed usage profiles or organisational changes
• Alignment with tax practice and fiduciary advisors, especially for declining-balance methods

Especially in the case of multiple assets and more complex structures, digital solutions such as Bill Bucher help to manage depreciation systematically and present it consistently in the fixed-asset register.

Equally important is integration into existing processes. Depreciation should be closely linked to the fixed-asset register, budgeting and investment planning. Only then does a continuous and reliable data basis emerge.

In many companies, depreciation is treated purely operationally. A strategic approach creates clear added value here: it improves planning reliability, increases transparency and reduces tax risks.

Regular reviews are crucial. In particular, when changes occur – such as new investments, growth or altered market conditions – the existing depreciation logic should be questioned and adjusted if necessary.

This creates a robust framework that better aligns financial reporting, management control and investment decisions.
