Prepare one comparable decision boundary
Before comparing the methods
- Choose one product, service or offer and one consistent unit. (not complete)
- Define which direct, variable and allocated costs belong inside the cost boundary. (not complete)
- Use one currency and one indirect-tax basis throughout. (not complete)
- Separate observed customer, segment and offer evidence from assumptions or opinions. (not complete)
- Name the volume, capacity or scope condition that would make either boundary unusable. (not complete)
Compare both methods on symmetric criteria
| Criterion | Cost-plus | Customer-value evidence |
|---|---|---|
| Question answered | What price follows from this cost boundary and markup? | What range might the defined offer and segment support? |
| Primary inputs | Relevant cost per unit and selected markup | Offer, segment, alternatives and observed customer evidence |
| Evidence needed | Current cost records, allocations and units | Research, tests or observed behaviour tied to the offer |
| Strength | Reproducible internal starting point | Challenges whether the offer supports more or less than cost alone suggests |
| Failure mode | Can ignore demand, differentiation, capacity and alternatives | Can ignore cost recovery or rely on weak evidence |
| Stop point | Cost boundary is incomplete or contribution is commercially unusable | Evidence is not comparable to the offer or segment being priced |
| Review trigger | Cost, scope, capacity or tax-basis change | Offer, segment, alternative or observed response changes |
Worked scenario: two boundaries for the same unit
All figures are user assumptions in generic currency units per unit, before indirect tax. The value test is not a demand forecast.
cost-plus price = relevant unit cost × (1 + selected markup)
- relevant unit cost
- Cost included in the selected pricing boundary (currency units per unit) — business record or user input
- selected markup
- Amount added relative to cost, expressed as a decimal (ratio) — user assumption
margin = (price - relevant unit cost) / price
- price
- Scenario selling price on the same basis as cost (currency units per unit) — calculated or user scenario
- relevant unit cost
- The same cost boundary used in the price comparison (currency units per unit) — business record or user input
| Measure | Cost-plus case | Value-test case |
|---|---|---|
| Relevant unit cost | 60 | 60 |
| Pricing input | 25% markup | 90 tested offer scenario |
| Scenario price | 75 | 90 |
| Contribution per unit | 15 | 30 |
| Margin on price | 20% | 33.3% |
The cost-plus calculation creates a reproducible 75 starting point. A separately evidenced 90 offer scenario would leave 30 contribution and about 33.3% margin on the same cost boundary. Compare expected scope, volume and capacity before treating either as usable.
Decide how to combine the boundaries
- Reconcile the cost-plus starting point and label markup versus margin correctly.
- Define the exact offer and segment represented by the customer-value evidence.
- Compare both boundaries under the same unit, scope and indirect-tax treatment.
- Test volume and capacity rather than assuming a formula-valid price will sell.
- Record the chosen scenario, evidence owner and trigger for review.
Cost-plus and value-based pricing questions
- Is value-based pricing always better than cost-plus?
- No. They answer different questions. Cost-plus creates a reproducible internal boundary, while customer-value evidence challenges what the offer may support. Either can fail when its inputs or evidence are weak.
- Can a business use both methods?
- Yes. Compare a complete cost boundary with evidence for a defined offer and segment, then test whether the resulting range remains feasible for volume, capacity and wider operating needs.
- Is a 25% markup the same as a 25% margin?
- No. Markup uses cost as the denominator; margin uses selling price. On a cost of 60, a 25% markup gives a price of 75 and a margin of 20%.
