fin.newsvendor-problem Calculator
Solves the newsvendor inventory optimisation problem — finding the order quantity that maximises expected profit under stochastic demand. The newsvendor model is the foundation of retail and airline revenue management — it applies whenever demand is uncertain and inventory expires.
Inputs
Cost Unit
Reference formula or conversion factor shown for context.
Price Unit
The price charged to customers. Getting this right relative to cost is the core of profitability.
Salvage Unit
Estimated resale or scrap value at the end of the asset's useful life. Reduces the depreciable amount.
Demand Mean
Arithmetic average. Sensitive to outliers — if your data has extreme values, the median may be more representative.
Demand Sd
Reference formula or conversion factor shown for context.
Results
critical ratio CR
The proportional relationship between two quantities.
optimal order quantity Q* (units)
Sample size or count used in the calculation.
underage cost Cu ($/unit)
The total monetary cost computed for the given inputs.
overage cost Co ($/unit)
The total monetary cost computed for the given inputs.
CR = Cu/(Cu+Co)
Reference formula or conversion factor shown for context.
Q* = μ + z(CR)·σ
