A rental fleet can serve two commercial purposes: generating rental earnings and providing machines for eventual sale. The way a business tracks those activities can influence which assets appear profitable, when managers want to sell them, and how they judge fleet performance.
One approach uses straight-line depreciation. Another is a rental-driven allocation in which 80% of rental receipts reduces the machine's recorded cost and 20% remains as rental income in the management view.
Those approaches can tell different stories about the same machine. Understanding the difference helps managers connect rental performance, resale opportunity, and capital allocation.
What the 80/20 approach is doing
In the approach discussed here, every $1,000 of rental receipts allocates $800 toward reducing the machine's internal recorded cost. The remaining $200 is presented as rental income after that allocation, before other costs.
That connects rental activity directly with cost recovery. A machine that rents frequently sees its recorded cost reduced more quickly. A machine that does not rent receives little or no reduction from this allocation alone.
This is different from depreciation based on operating hours. It is also different from activity-based costing, which assigns costs according to activities that consume resources, such as deliveries or inspections.[1]
The terminology matters. The 20% figure should not automatically be treated as gross rental revenue on the financial statements. An internal allocation, revenue recognition, depreciation expense, and tax treatment are separate questions. Finance needs to reconcile the management view with the applicable accounting requirements. Under IFRS, revenue-based depreciation is specifically prohibited.[2]
This article examines the decision-making effects of the 80/20 management model described above. It does not prescribe financial-statement entries or present 80/20 as a universal industry standard.
Compare the same machine under both approaches
Assume a machine costs $100,000 and generates $30,000 in rental receipts during a full year. For the straight-line comparison, assume a five-year useful life and a $40,000 residual value. That produces $12,000 in annual depreciation.
Under the 80/20 allocation, $24,000 reduces the machine's internal recorded cost and $6,000 remains in the rental income view before other costs.
The straight-line view shows a stronger rental contribution in this period. The 80/20 view shows a lower recorded machine cost, which can make its later resale margin appear stronger.
The cash collected from customers is identical. Neither method creates additional demand or improves the sale price by itself.
The result may move from rental to resale
Now assume the machine is sold at year-end for $90,000, with no selling costs or other adjustments.
The combined result is the same: $30,000 in rental receipts plus $90,000 in sale proceeds, less the $100,000 acquisition cost. Both produce $20,000 before operating costs, financing costs, taxes, and selling costs.
What changes is where the result appears. One presentation assigns more contribution to rental. The other assigns more to disposal.
That distinction matters when rental and sales teams have separate targets. A manager looking only at rental contribution could prefer the first view. A manager rewarded for resale margin could prefer the second. The organization needs a consistent view of the complete asset result.
A lower recorded cost can influence pricing
The 80/20 approach can help managers see rental receipts contributing toward cost recovery before a machine is sold. It can also create a temptation to base the asking price on the reduced recorded cost.
A machine with a recorded cost of $76,000 might appear to offer substantial pricing flexibility. But recorded cost does not establish what the market will pay. Comparable sales, condition, hours, demand, and available alternatives should inform the price.
An attractive resale margin may partly reflect earlier rental allocations. It does not, by itself, demonstrate better selling performance. Review total rental receipts and disposal contribution together before interpreting the outcome.
Idle machines need a separate review
Under straight-line depreciation, a continuing time-based charge can make low utilization visible in the rental result. Under the 80/20 model, an idle machine may receive no rental-driven reduction and retain a relatively high internal value.
That does not mean its market value has remained unchanged. Age, condition, changing demand, and newer alternatives can affect the price a buyer will pay. A recorded cost that depends on rental receipts needs an independent comparison with current market evidence.
Investigate why the machine is idle. Is it in the wrong location? Is it unavailable because of repairs? Is it serving a seasonal or strategic need? Is the asset category oversized relative to expected demand?
The accounting view helps frame the question. The fleet strategy determines the response.
More rental receipts do not automatically mean a better outcome
In the 80/20 model, additional rentals reduce internal recorded cost further. Managers may therefore see a reason to keep renting a machine before selling it.
That decision still needs to consider incremental rental earnings after service and delivery costs, expected wear, upcoming repairs, possible changes in sale proceeds, and the capital tied up while the machine remains in the fleet.
Rental dollars are not a direct measure of physical consumption. Two machines can earn the same rental amount while accumulating different hours or experiencing different operating conditions. A higher rental rate can also produce a larger allocation without a corresponding increase in wear.
Evaluate the next rental on its expected economic contribution and its effect on future options. A lower recorded cost is one consequence of the model, not the purpose of the decision.
Manage the asset's full commercial life
A useful fleet review brings together acquisition cost, gross rental receipts, the internal allocation, operating costs, utilization, hours, condition, current net resale proceeds, and future demand.
Keep the management allocation visible and reconcile it with the financial accounts. Avoid subtracting both an 80% allocation and a separate depreciation charge from the same management contribution unless their relationship is explicitly explained and reconciled. Set clear limits and review rules as an asset approaches its defined residual or minimum recorded value.
For a hold-or-sell decision, compare the expected future cash contribution from retaining the machine with selling it now and deploying the capital elsewhere. Include replacement requirements and customer commitments. Historical recorded cost helps explain the reported sale result, but should not determine the decision on its own.
Five Needles Consulting helps connect these financial and operating views. We work with finance and fleet teams to clarify measures, organize asset information, evaluate rental and resale performance, and establish a recurring review with clear actions and owners.
The question is how the business can earn the best overall result from its assets and capital. Understanding the allocation method helps keep that decision grounded in the full commercial picture.
