Depreciation & Valuation

Track how assets lose value over time with straight-line, declining balance, or units-of-production depreciation methods.

Most physical assets lose value over time through wear, obsolescence, or age. Eleo’s depreciation engine automatically calculates how much value each asset has lost and maintains an up-to-date book value. This helps you understand the true worth of your assets, plan for replacements, and keep your financial records accurate.

Depreciation methods

Eleo supports four depreciation methods. The method you choose determines how the asset’s cost is allocated over its useful life.

Straight-line

The most common method. The asset loses an equal amount of value in each period over its useful life.

Annual depreciation = (Acquisition cost − Salvage value) ÷ Useful life in years

For example, a piece of equipment purchased for 1,000,000 with a salvage value of 100,000 and a useful life of 5 years would depreciate by 180,000 per year.

Declining balance

A percentage of the asset’s remaining book value is depreciated each period. This results in higher depreciation in the early years and lower amounts as the asset ages.

Annual depreciation = Book value at start of year × Depreciation rate

This method is often used for assets that lose value quickly in their first few years, such as vehicles and electronics.

Units of production

Depreciation is based on actual usage rather than time. You define the total expected units of production (e.g. kilometres, hours, or units manufactured), and depreciation is calculated proportionally as usage is recorded.

Depreciation per unit = (Acquisition cost − Salvage value) ÷ Total expected units

This method is ideal for machinery, vehicles, and equipment where wear is driven by usage rather than age.

None

Some assets do not depreciate — for example, land or certain collectibles. Select “None” to skip depreciation entirely. The asset’s book value will remain equal to its acquisition cost unless manually adjusted through revaluation.

Configuration

Each asset’s depreciation is controlled by two key settings:

  • Useful life (years) — The number of years over which the asset is expected to provide value. For straight-line and declining balance methods, this determines the depreciation period.
  • Salvage value — The estimated residual value of the asset at the end of its useful life. Depreciation stops once the book value reaches the salvage value.
Set up category-level defaults

Instead of configuring depreciation for each asset individually, define default depreciation method, useful life, and salvage value on your asset categories. New assets assigned to a category will inherit these settings automatically.

Current book value

An asset’s current book value represents its worth on the books after accounting for all depreciation, revaluations, and impairments:

Book value = Acquisition cost − Accumulated depreciation ± Revaluation adjustments

The book value is recalculated automatically each month when depreciation runs. You can view the current book value on the asset detail page, and historical values are available in the valuation history.

Revaluation

There are times when an asset’s actual value differs significantly from its book value. Revaluation allows you to adjust the recorded value to reflect reality:

  • Impairment — A downward adjustment when an asset’s recoverable amount falls below its book value, for example due to damage or market changes.
  • Appreciation — An upward adjustment when an asset’s fair value has increased, such as property in a rising market.

To revalue an asset, navigate to its detail page, click Revalue, enter the new value and a reason, and confirm. The adjustment is recorded in the valuation history with the date, type, and the user who performed it.

Valuation history

Every change to an asset’s value is recorded as a valuation event. The valuation history provides a complete audit trail of how the asset’s book value has changed over time. Events tracked include:

  • Initial — The acquisition cost recorded when the asset was first registered.
  • Depreciation — Monthly depreciation amounts calculated by the system.
  • Revaluation — Manual adjustments to the asset’s value.
  • Impairment — Downward adjustments due to damage, obsolescence, or market decline.
  • Appreciation — Upward adjustments reflecting increased fair value.
  • Disposal — The final valuation event recorded when the asset is disposed of.
The asset detail page displays the current book value, depreciation method, and a timeline of valuation events.

Monthly depreciation runs automatically. Eleo calculates and records depreciation at the start of each month for all active assets. No manual action is required — the system handles everything based on each asset’s configured method and useful life.
