The asset lifecycle is the sequence of stages an owned thing passes through between the purchase order and the day it leaves, and the register's job is to record which stage every asset is in and when it got there. The stages look different in every vendor's diagram, but for the person keeping the register of a company, a school, a church or a laboratory they reduce to four: acquisition, use, transfer and disposal. Each stage has one question the register must be able to answer, one thing it records, and one effect on the depreciation. This page walks the four stages with a single asset, a workshop machine, so the arithmetic and the records are concrete rather than a diagram.
Stage one, acquisition: the line is opened with its cost and its life
The machine is ordered for $18,500 delivered and installed. The register opens a line with that cost, the supplier, the serial number when it arrives, an expected salvage value of $1,500, and a five-year useful life. Nothing depreciates yet; the line is on order until the machine is in service. What the stage has to get right is the cost, because everything the register says for the next five years is arithmetic on it: freight and installation belong on the line, the first year's service contract does not.
Stage two, use: the depreciation runs and the holder is named
The machine goes into service on a date, and from that date the straight-line depreciation is $3,400 a year, or $283.33 a month, and the book value falls by that amount each period. The register names a holder and a location and records the physical count each year with what was found. This is the stage the register spends most of its life in, and the one where spreadsheets fail: the depreciation is recomputed by hand each January and the holder column is whoever was there when the sheet was made.
Stage three, transfer: the holder or the location changes, the cost does not
The machine moves to a second workshop, or a laptop moves from a leaver to a starter. The register records the new holder or location with the date and keeps the old one. The cost, the life and the depreciation are untouched; a transfer is a change of custody, not a change of value. Organisations that skip this stage discover at the annual count that the register knows what they own but not where any of it is, which is the same as not knowing.
Stage four, disposal: the line closes with a date and the proceeds
After two years the machine is sold for $12,000. The register closes the line on the sale date with the proceeds beside the net book value on that date, $11,700 by the straight-line method, so the $300 gain is on the register rather than in someone's head. The line stays on the register as closed; it is not deleted, because the year's fixed asset report has to show what left. For a device with storage, the disposal row also carries the record that the data was wiped.
Questions people ask about asset lifecycle
How many asset lifecycle stages are there?
Vendors draw anywhere from four to eight. For a small organisation's register, four are enough: acquisition, use, transfer and disposal. Maintenance and refurbishment stages belong to a maintenance record, which is a different product for a different person.
What is the difference between the asset lifecycle and the asset management lifecycle phases?
Nothing that matters to the register. One describes what happens to the asset, the other what the organisation does about it; both are the same four stages with the same records at each.
Does depreciation run through every stage?
Only through use and transfer. It starts on the in-service date, continues unchanged through a transfer, and stops on the disposal date or when the asset is fully depreciated to its salvage value, whichever comes first.
What if an asset is fully depreciated but still in use?
It stays on the register at its salvage value, still in the use stage, with its holder and location, until it is disposed of. A fully depreciated asset is still owned, and the register exists to say what is owned.
