How do you simulate a price-volume-margin scenario?
The scenario turns a demand assumption into volume, revenue and contribution. It must propagate elasticity uncertainty and separate variable cost, fixed cost and horizon.
Direct answer
Compare conditional scenario contribution and break-even thresholds.

01
Direct answer
A price-volume-margin scenario combines a price, demand model and costs over a declared horizon. In MSC-P-024, a 5% price increase gives 9,339.74 units and €11,987.21 incremental profit after €5,000 extra fixed cost.
02
Scientific question
Under an explicitly conditional demand response and cost structure, what contribution does each price produce and where is break-even?
03
Population, unit and horizon
The unit is product × market × scenario × period. Price, volume, variable and fixed costs must cover the same period and commercial population.
04
Decision target
The target is ΔΠ=C₁−C₀−ΔFC, where C=(P−VC)Q. It is conditional on the scenario, not a guaranteed forecast.
05
Required data
Use baseline price and volume, unit variable cost, price change, elasticity or demand function, fixed-cost change, taxes, discounts, capacity and horizon.
06
Assumptions
Assume constant elasticity over a 5% change, constant unit cost, no competitor response and sufficient capacity. Any causal reading depends on upstream demand identification.
07
Model
P₁=P₀(1+d), Q₁=Q₀(1+d)^ε, C₀=(P₀−VC)Q₀, C₁=(P₁−VC)Q₁ and ΔΠ=C₁−C₀−ΔFC.
08
Reproducible calculation
The script reads one row, validates price, cost and volume, calculates volume by exponentiation, then reports contributions, incremental profit and two break-even measures.
09
Results
P₁=€105, Q₁=9,339.744; C₀=€450,000, C₁=€466,987.209; ΔΠ=€11,987.209, or +2.6638% of baseline contribution.
| Metric | Baseline | Scenario |
|---|---|---|
| Price | €100 | €105 |
| Volume | 10,000 | 9,339.744 |
| Contribution | €450,000 | €466,987.209 |
| Δ profit after ΔFC | — | €11,987.209 |

Uncertainty
The point result contains no uncertainty. At minimum, propagate uncertainty in elasticity, volume and cost, then report an interval and loss probability as in MSC-P-034.
11
Thresholds and sensitivity
Break-even volume at €105 is 9,100 units. The scenario supports at most €16,987.21 additional fixed cost before ΔΠ turns negative.
12
Diagnostics
Check currency units, tax, discounts, cost signs, period, elasticity support, capacity, competitor response and consistency with MSC-P-022.
13
Common errors
Common errors are using ε×d instead of (1+d)^ε−1 for a finite change, confusing revenue with contribution, omitting ΔFC, mixing unit and total costs, or extrapolating.
14
Interpretation
The reference scenario is favourable under its assumptions, but its volume safety margin is only 239.74 units. This fragility calls for probabilistic analysis.
15
Supported decision
Compare nearby scenarios, identify volume or cost thresholds, and decide which uncertainties must be reduced before a price test.
16
Unsupported decision
Do not announce an optimal price, certain profit or causal effect without competitor response, operational constraints, identification and uncertainty propagation.
17
Implementation
The CC0 CSV fixes assumptions and the MIT Python script recalculates them without dependencies. Together they are the dossier’s executable reference.

Expected deliverable
Provide one table per scenario with assumptions, unit, horizon, volume, revenue, contribution, ΔΠ, thresholds, uncertainty, constraints and supported/unsupported decision.

Scientific sources
Tellis supports the elasticity definition and transformation. Contribution arithmetic is a declared accounting identity. The source validates neither the costs nor synthetic MSC-P-024 scenario.
