Use the same work and ownership period for both options
A vehicle can move cost from the purchase price into shipping, maintenance or downtime. A lifecycle comparison helps reveal that shift, provided both alternatives do the same work over the same period. Changing utilization or the ownership horizon can change the preferred option.
Put a source, date and currency beside every amount, and distinguish a quotation from an estimate. Keep recoverable taxes and pass-through charges separate from operating costs. Where the fleet has no reliable record, show a scenario rather than a precise-looking forecast.
Keep acquisition costs and operating assumptions visible
The model should show which assumption drives the decision. A single maintenance percentage or guaranteed-looking resale figure hides the uncertainty that the buyer most needs to understand. Use local records where available and show a range where they are not.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Landed cost | Capture every cost through the agreed handover point. | Do not mix supplier and buyer responsibilities under different delivery terms. |
| Operating horizon | Use the same period and utilization basis for all alternatives. | Different horizons can reverse a comparison. |
| Maintenance and downtime | Use local records or explicitly labeled scenarios. | Generic percentages are not evidence for a specific fleet. |
| Residual value | Keep it as a transparent sensitivity input. | It is uncertain and should not be presented as guaranteed. |
Separate landed cost from lifecycle scenarios
Calculate the purchase and delivery costs first. Estimate operating costs separately, using documented assumptions.
The only firm result in the example is the 107,000 USD landed starting cost. Lifecycle totals remain scenarios until local utilization and maintenance inputs are supplied.

| Step | Calculation or condition | Result |
|---|---|---|
| Landed starting cost | 92,000 + 11,500 + 3,500 | 107,000 USD |
| Operating scenario | Maintenance + consumables + downtime for the chosen horizon | Add local records or a range |
| Lifecycle comparison | Landed cost + operating scenario − residual value | Compare on one common basis |
- Vehicle and options: 92,000 USD
- Freight, insurance and destination handling: 11,500 USD
- Registration and local preparation: 3,500 USD
Illustrative numbers only. Taxes, duties, exchange rates, downtime and residual value require current local evidence and professional review.
Choose a cost unit that matches the job
A larger vehicle can cost more per day yet less per completed job. It can also be the wrong choice if access restrictions or low utilization leave its capacity unused. Compare the same work, including empty travel, refilling or unloading, and time out of service.

| Comparison | Useful cost unit | Inputs to obtain |
|---|---|---|
| 3-ton versus 6-ton wrecker | Cost per compatible recovery or transport job | Jobs each configuration can accept, loaded and empty distance, operator time, inspections and parts |
| Garbage-truck sizes | Cost per route or tonne collected | Weighed waste, stops, disposal trips, crew hours, fuel and packing-system maintenance |
| 10,000 L versus 20,000 L fuel tanker | Cost per legally delivered litre | Cargo density, usable payload, delivery split, depot loading time, meter service and empty travel |
| Crane configurations | Cost per completed delivery and lift | Load at the required radius, setup time, payload lost to the crane, inspection and service |
| Mechanical refrigeration versus eutectic storage | Cost per compliant route | Route duration, charging or cooling time, energy, payload loss and the cargo temperature requirement |
These are comparison inputs, not prices or savings claims. Without matched quotations and operating records, none of these pairs has a defensible cost winner.
When repair stops making sense
There is no single replacement age for a special-vehicle body. Compare the condition report, recurring faults, downtime, parts availability and the cost of the next major repair with the remaining useful work. Keep safety separate from the cost calculation: structural damage or an unresolved safety defect needs a qualified assessment before further use.
Use conservative, central and adverse cost scenarios. If the decision changes with a small assumption about downtime or resale value, collect better evidence on that item before approving the purchase. Do not turn an illustrative scenario into a promised service life.
Record which delivery costs the quoted term includes
Keep the configuration and quantity fixed when comparing costs, with the same currency and quotation-validity basis. Record the named delivery place and Incoterms edition. ICC explains the allocation of responsibilities under the term; you still need actual freight quotes and applicable duty assessments to calculate the landed price.

Illustrative arithmetic in arbitrary cost units: vehicle and agreed options 100 + origin handling 5 + freight and insurance 10 + destination charges 8 = 123. The inputs are invented, not market prices, a KEEYAK quotation or a tax calculation. Replace them with dated offers or applicable assessments, checking that an included charge is counted only once.

| Cost group | Keep on the same basis | Record inclusion or exclusion |
|---|---|---|
| Vehicle and options | Same signed specification and quantity | Body, chassis, equipment, spares and inspection |
| Transport and handling | Same named delivery place and shipment assumptions | Origin, freight, insurance, terminal and inland charges |
| Destination and operation | Applicable classification and actual duty cycle | Taxes, registration, fuel, service, downtime and residual assumptions |
Investigate the assumption that changes the decision
Compare conservative, central and adverse cases using the same cost responsibilities and tax treatment. If a small change in downtime or residual value reverses the result, better evidence for that item is more useful than adding decimal places to the total.
Information to prepare for this review
- Vehicle and option quotation
- Delivery term, origin and destination
- Freight, insurance and port estimates
- Import, tax and registration assumptions
- Expected utilization and maintenance plan
- Downtime method and residual-value assumption
Records to request and keep
- Dated quotation and option schedule
- Written freight and destination-cost assumptions
- Local maintenance or fleet records used in the model
- Versioned worksheet with source and confidence for each line
Common mistakes and what to check instead
- Using one unsupported maintenance percentage: Build component and service scenarios from available records.
- Mixing tax-inclusive and tax-exclusive totals: State tax treatment for every option.
- Presenting uncertain downtime as a precise forecast: Use a range and show which assumption changes the decision.
Scope of this guide
The model is not financial, tax or customs advice.
Freight, exchange rates, taxes and operating costs require current local inputs.
Do not approve a comparison when major cost responsibilities or model bases differ between options.
