Responsibility accounting and transfer pricing
A selling division’s minimum transfer price is incremental cost plus opportunity cost. The buying division’s ceiling is its relevant outside alternative. Check capacity and company-wide contribution before evaluating divisional profit.
Find the transfer-price range
- Seller minimum
- Incremental cost + contribution lost on displaced sales.
- Buyer maximum
- Relevant cost of the outside alternative.
- Feasible transfer
- Seller minimum ≤ transfer price ≤ buyer maximum.
Adjust the outside comparison for quality, freight and other relevant differences. Idle capacity can make opportunity cost zero.

Capacity changes the negotiation range
A component has $28 incremental production cost. The buyer can purchase externally for $42. With idle capacity, no sales are lost. With full capacity, an internal unit displaces $18 contribution.
USD per component
- Idle minimum$28
- Outside quote$42
- Full-capacity minimum$46
Internal transfer is economically attractive with idle capacity under these assumptions; at full capacity the outside purchase is $4 cheaper for the company.
How to apply these ideas
1. Decision authority
Evaluate managers on measures consistent with their control.
A cost center manages costs; an investment center also manages the asset base. Transfer prices move reported profit between units, so the performance system must distinguish divisional incentives from company-wide economics.
Watch for: Assuming a higher selling-division profit raises group profit.
2. Minimum price
Add avoidable production cost and contribution displaced elsewhere.
Idle capacity can make opportunity cost zero. At full capacity, internal supply may displace external contribution. Use the actual bottleneck and avoidable selling costs; a listed market price is not automatically the opportunity cost.
Watch for: Using zero opportunity cost when external sales are displaced.
3. Maximum price
Use the buyer’s relevant alternative cost.
Adjust an outside supplier quote for freight, quality, reliability and other stated differences. The feasible negotiation range exists only where the buyer’s ceiling covers the seller’s minimum. Nonfinancial constraints can change the decision.
Watch for: Comparing an all-in internal cost with a partial supplier quote.
4. Goal congruence
Choose a policy that supports the best total-company action.
Market, cost-based and negotiated prices have different incentive effects. A policy can require adjustments where reported divisional profit discourages an economically sound transfer. Explain that incentive issue rather than declaring one method universally best.
Watch for: Letting unchanged allocated fixed cost veto a beneficial transfer.

Responsibility accounting and transfer pricing: explanations and applications
Evaluate managers using controllable measures and derive a transfer-price range from capacity and outside alternatives. Performance management remains the parent for the full evaluation framework.

Align responsibility centers with actual authority
A cost center controls resources, a revenue center sales, a profit center revenues and costs, and an investment center also influences invested assets. These classifications describe responsibility, not organizational prestige. A manager cannot be held meaningfully accountable for a measure without sufficient authority and a defined evaluation period.
Traceability and controllability differ. Depreciation on a dedicated facility is traceable to a division but may reflect an investment made before the current manager arrived. Report it for divisional economics while distinguishing it from the manager’s short-term controllable result. Common allocations should remain visible without being mistaken for costs the manager can remove.
Derive both sides of the bargaining range
The seller’s economic minimum is incremental transfer cost plus opportunity cost. With genuine idle capacity, lost outside contribution can be zero. With full capacity, supplying the internal buyer may displace external sales; include the contribution forgone after any selling costs avoided on the transfer.
The buyer’s maximum is the cost of an equivalent outside alternative, adjusted for quality, transport, service and other differences. A feasible range exists only when the minimum does not exceed that maximum. The negotiated price distributes divisional profit inside the range; the company-wide benefit comes from the real cost difference, not from changing the internal invoice.
| Method | Useful feature | Potential distortion |
|---|---|---|
| Market-based | External opportunity benchmark | Market may not be competitive or comparable |
| Variable-cost | Signals short-run incremental production cost | May not support seller cost recovery or incentives |
| Full-cost plus markup | Includes allocated commitments and a margin | Can transmit inefficiency or obscure opportunity cost |
| Negotiated | Allows local information and autonomy | Bargaining power may dominate economics |
| Dual-rate system | Can support different decision and evaluation goals | Needs transparent reconciliation at group level |
Check the group result and incentive consequences
An internal sale is revenue to one unit and cost to another, and those amounts cancel in consolidated profit. Compare the external revenue gained or lost and the actual resource costs. A price that improves one division’s score can still cause rejection of a group-beneficial transfer if the other division is measured inconsistently.
Use capacity facts for the relevant period. Long-run expansion may make additional fixed cost relevant even when current spare capacity suggests a low short-run minimum. International transfers also involve tax, customs, exchange controls and legal requirements; a managerial bargaining range alone does not establish an acceptable tax transfer price.
Work it through
Worked example: Capacity changes the negotiation range
A component has $28 incremental production cost. The buyer can purchase externally for $42. With idle capacity, no sales are lost. With full capacity, an internal unit displaces $18 contribution.
| Capacity | Seller minimum | Buyer maximum | Range |
|---|---|---|---|
| Idle | $28 | $42 | $28 to $42 |
| Full | $46 | $42 | No feasible range |
- 1
Idle capacity minimum = 28 + 0 = $28.
- 2
Full capacity minimum = 28 + 18 = $46, above the $42 outside alternative.
Internal transfer is economically attractive with idle capacity under these assumptions; at full capacity the outside purchase is $4 cheaper for the company.

Original teaching scenarios. Each case states its assumptions, shows the working and explains the limits of the conclusion.
The same transfer has different economics at full capacity
A seller’s variable production cost is $22. Its external price is $38 and external selling cost is $3, avoided on internal transfers. The buyer can buy an equivalent item outside for $32. Evaluate one unit under idle and full capacity.
| Condition | Seller minimum | Buyer maximum | Group implication |
|---|---|---|---|
| Idle capacity | $22 | $32 | $10 benefit from internal supply |
| Full capacity with displaced outside sale | $35 | $32 | $3 disadvantage from internal supply |
- With idle capacity, minimum equals $22 and the company avoids a $32 outside purchase by spending $22 internally.
- With full capacity, outside contribution lost is 38 - 22 - 3 = $13. Minimum = 22 + 13 = $35, above the buyer’s $32 alternative.
What the result means: A $22 variable-cost transfer price can be useful in the idle-capacity case and misleading in the constrained case. Capacity and avoided selling cost drive the conclusion.

Try each short application before opening its explanation. These are original learning checks, not official exam questions or a score prediction.
1. A division earns $75,000 on $400,000 investment with a 15% required return. What is residual income?
Show answer and explanation
$15,000.
The capital charge is $60,000. Subtract it from operating income using consistent definitions.
2. A negotiated internal price increases by $5 per unit with no change in output, taxes or external costs. Does consolidated profit rise?
Show answer and explanation
No.
Seller profit rises and buyer profit falls by equal amounts. Real behavior can change later, but the price change alone cancels within the group.
Questions about responsibility accounting and transfer pricing
- Does a transfer price change consolidated profit?
- The internal price itself cancels within the group. The production, sourcing and selling decisions it encourages can change total profit.
- Must fixed costs always be excluded?
- Exclude unchanged allocations from incremental decisions. Include fixed costs that are actually added or avoided because of the decision.
