TL;DR key takeaways
Transfer pricing examples only make sense after the controlled transaction is accurately delineated: what is being transferred, which party performs which functions, and which risks each party controls.
CUP tests the transaction price directly; RPM and cost plus test gross margins; TNMM tests a net profit indicator; profit split allocates combined profit between parties.
The same fact pattern can produce different-looking calculations depending on whether you solve for the transfer price, the tested party return, or a year-end adjustment.
For routine distributors, manufacturers, and service providers, one-sided methods such as RPM, cost plus, or TNMM are usually easier to apply than profit split.
For highly integrated businesses or transactions involving unique contributions by both parties, profit split may be more reliable than forcing a one-sided benchmark.
How to price contract and toll manufacturing arrangements: tested party selection, cost plus vs TNMM, cost-base design, capacity utilization, inventory and warranty risk, benchmarking, documentation, and audit issues.
How to price contract R&D arrangements: distinguishing routine research services from entrepreneurial IP development, DEMPE and risk control, cost plus vs TNMM, cost-base and mark-up issues, tax/accounting caveats, documentation, audit issues, and examples.
Cost plus and TNMM can both use costs as a reference point, but they are not the same transfer pricing method. This guide explains gross mark-up vs net cost plus, when each method fits, examples, audit risks, and documentation points.

The five main transfer pricing methods answer different pricing questions:
Method
Example question
Typical calculation output
CUP
What price did independent parties charge for the same or highly comparable transaction?
Arm's length price per unit
Resale Price Method (RPM)
What gross margin should a routine reseller keep?
Transfer price from resale price minus gross margin
Cost Plus
What gross mark-up should a routine supplier earn on production or service costs?
Transfer price from cost base plus gross mark-up
TNMM
Is the tested party's net profit in line with comparable companies?
Arm's length operating margin, net cost plus, or other PLI
Profit Split
How should combined profit be divided when both parties make unique contributions?
Allocation of combined profit between related parties
Note
Examples are simplified. In real documentation, the calculation sits behind the functional analysis, tested party selection, comparability analysis, data screening, and method selection narrative. Start with the full transfer pricing methods guide if you need the method-selection logic before the math.

Question
Why it matters
What is being transferred?
Goods, services, IP, financing, or a bundle may require different methods.
Who performs the key functions?
Routine execution points toward one-sided methods; unique contributions may point toward profit split.
Which assets are used?
Manufacturing assets, inventory, marketing intangibles, and IP ownership affect expected returns.
Which risks are controlled?
Market, inventory, product, credit, and capacity risks affect the arm's length reward.
What reliable data exists?
A perfect-looking method fails if the comparables or segmentation are not reliable.
The examples below assume the facts have already been delineated and focus on mechanics.
Example 1: CUP Method
Fact Pattern
ParentCo sells the same commodity-grade input to:
a related manufacturer, SubCo; and
an unrelated customer in the same market.
The uncontrolled sale is close in product specification, timing, currency, delivery terms, and volume. The only material difference is freight: ParentCo pays freight in the related-party sale, while the unrelated customer pays freight separately.

Calculation
text
Comparable uncontrolled price = $102.00
Less freight adjustment = $2.00
Arm's length controlled price = $100.00 per unit
If ParentCo charged SubCo $96.00 per unit, the tested price is below the adjusted CUP by $4.00 per unit.
CUP is the most direct method when a sufficiently comparable uncontrolled transaction exists. The hard part is not the arithmetic. The hard part is proving that differences in product, volume, contract terms, timing, market level, geography, and risk either do not materially affect price or can be reliably adjusted.
Tip
Internal CUPs are often more persuasive than broad external market observations because the taxpayer can usually explain product specifications, terms, volumes, and timing in more detail.
ManufacturerCo sells finished goods to DistributorCo, a related limited-risk distributor. DistributorCo resells the products to independent customers without material transformation. DistributorCo performs routine sales, warehousing, and order fulfillment, but does not own valuable marketing intangibles.
Independent distributors performing similar functions earn gross margins between 22% and 28%, with a median of 25%.

Calculation
RPM starts from the resale price and backs into the transfer price by leaving the distributor an arm's length gross margin.
text
Arm's length gross profit = Resale revenue x gross margin
Arm's length gross profit = $1,000,000 x 25%
Arm's length gross profit = $250,000
Arm's length transfer price = Resale revenue - arm's length gross profit
Arm's length transfer price = $1,000,000 - $250,000
Arm's length transfer price = $750,000
At a $750,000 purchase price, DistributorCo keeps $250,000 of gross profit. After $180,000 of operating expenses, it earns $70,000 of operating profit.
RPM is a gross-margin method. It is strongest when the reseller's functions and accounting are comparable to the distributors used as benchmarks. It can be less reliable where gross profit is distorted by inconsistent classification of discounts, freight, warranty costs, rebates, or selling expenses.
Warning
Do not use RPM only because the tested party is called a distributor. If the reseller performs significant manufacturing, owns valuable local marketing intangibles, or bears major entrepreneurial risks, a simple gross-margin resale method may understate its contribution.
ContractManufacturerCo manufactures components for PrincipalCo under PrincipalCo's specifications. PrincipalCo owns product IP, controls market risk, and commits to purchase the output. ContractManufacturerCo performs routine manufacturing and does not own unique intangibles.
Comparable independent contract manufacturers earn gross mark-ups on production costs between 8% and 12%. The selected point is 10%.

Arm's length gross mark-up = Production cost base x mark-up
Arm's length gross mark-up = $3,000,000 x 10%
Arm's length gross mark-up = $300,000
Arm's length transfer price = Production cost base + gross mark-up
Arm's length transfer price = $3,000,000 + $300,000
Arm's length transfer price = $3,300,000
What This Example Shows
Cost plus works when the supplier's cost base is a reliable measure of its value-creating activity. The key judgment is defining the cost base consistently with the comparables.
Cost item
Common treatment question
Direct materials
Included if the manufacturer bears procurement and production responsibility.
Pass-through costs
Often excluded or separately reimbursed if no value is added.
Idle capacity costs
Need fact-specific treatment; may not be fully chargeable to the principal.
Stock-based compensation or unusual charges
Require consistency with the benchmark and local rules.
Warning
Cost plus is a gross method. A TNMM "net cost plus" PLI is different: it usually tests operating profit over total operating costs. The names sound similar, but the profit line and cost base are not the same.
ServiceCo provides routine IT support services to group companies. It uses no unique technology, bears limited commercial risk, and is selected as the tested party. Independent comparable service providers earn net cost plus returns between 5% and 9%, with a median of 7%.

Calculation
First calculate the tested party's actual PLI.
text
Actual net cost plus = Operating profit / operating costs
Actual net cost plus = $200,000 / $4,000,000
Actual net cost plus = 5.0%
If the policy uses the median point of 7%, calculate the target operating profit and revenue.
text
Target operating profit = Operating costs x selected net cost plus
Target operating profit = $4,000,000 x 7%
Target operating profit = $280,000
Target service revenue = Operating costs + target operating profit
Target service revenue = $4,000,000 + $280,000
Target service revenue = $4,280,000
The year-end true-up required to reach the selected point is:
text
True-up = Target service revenue - actual service revenue
True-up = $4,280,000 - $4,200,000
True-up = $80,000
What This Example Shows
TNMM does not usually price an individual invoice directly. It tests whether the tested party's net profitability is arm's length. The practical output is often a policy rate, a target PLI, or a year-end adjustment.
Tip
Use a PLI that matches the tested party's value driver. Net cost plus often fits routine services and contract manufacturing. Operating margin often fits routine distributors. Return on assets is more relevant where operating assets drive value.
USCo and EUCo jointly develop and commercialize a software platform. USCo contributes core engineering IP and product architecture. EUCo contributes market-specific product design, major customer relationships, and regional commercialization know-how. Both parties make unique and valuable contributions, and reliable one-sided comparables do not capture the combined value creation.
The group applies a residual profit split:
Allocate routine returns to routine functions.
Split residual profit based on relative contributions to unique value.

What This Example Shows
Profit split is not just TNMM with a different label. It is a two-sided method that requires reliable combined profit data and a defensible allocation key. It is most useful when each party's contribution is too important to leave as an untested residual.
Note
The OECD guidance treats profit split as potentially appropriate where parties make unique and valuable contributions, operations are highly integrated, or parties share economically significant risks. The method can be powerful, but it is data-intensive.
Use this table as a starting point, not as a substitute for method selection.
Fact pattern
Method to consider first
Why
Same product sold to related and unrelated parties under comparable terms
CUP
Direct price evidence may exist.
Routine distributor resells finished goods without transformation
RPM or TNMM
RPM if gross-margin comparability is strong; TNMM if net-level data is more reliable.
Contract manufacturer produces under principal specifications
Cost plus or TNMM
Cost plus if gross cost mark-ups are reliable; TNMM if net margins are more reliable.
Routine intra-group service provider
Cost plus or TNMM
Cost base is usually the value driver.
Limited-risk distributor with reliable public company data but weak gross margin consistency
TNMM
Net margins may be more reliable than gross margins.
Commodity transaction with quoted market prices
CUP
Market price data may support direct price testing.
Both parties own valuable intangibles or jointly control key risks
Profit split
One-sided methods may leave too much value as an untested residual.
Bundled transaction with goods, services, and IP
Depends on delineation
You may need to separate components or test the bundle if separation is unreliable.
Warning
The "best-looking" calculation is not always the most appropriate method. The method has to follow the facts, available data, and reliability of comparability adjustments.
Common Mistakes in Transfer Pricing Examples
Mistake
Why it matters
Jumping straight to TNMM
You may miss a reliable CUP or gross-margin method.
Using RPM for a distributor with major local intangibles
Routine distributor margins may not reward the real value contribution.
Calling TNMM "cost plus"
Net cost plus under TNMM is not the OECD gross cost plus method.
Ignoring pass-through costs
Including large pass-throughs can dilute or distort mark-ups.
Applying profit split without combined profit data
The method needs reliable financial segmentation across parties.
Treating an example as a safe harbor
Worked examples illustrate mechanics; they do not replace benchmarking or local law.
FAQ
What is the easiest transfer pricing method to calculate?
TNMM is often easier to apply in practice because public company net margin data is more available than exact transaction-price or gross-margin comparables. That does not mean TNMM is always the most reliable method. If a reliable CUP exists, it may provide a more direct measure.
Is cost plus the same as TNMM net cost plus?
No. The OECD cost plus method is a gross profit method that applies a mark-up to an appropriate cost base. TNMM net cost plus is a net profit indicator, usually operating profit over total operating costs. They can produce similar-looking mark-up percentages but test different profit levels.
When should I use RPM instead of TNMM?
RPM is stronger when the tested party is a routine reseller and reliable gross-margin comparables are available. TNMM may be more reliable when gross margins are distorted by accounting differences but net operating results are comparable.
Can a company use more than one transfer pricing method?
Yes, but documentation should identify the most appropriate method. A secondary method can be used as a corroborative check, especially where the primary method has data limitations.
Are these examples enough for documentation?
No. A defensible local file or master file needs functional analysis, transaction delineation, method selection, comparable search logic, financial data, adjustments, and jurisdiction-specific disclosures. These examples show calculation mechanics only.
