Resale & sizing formulas
Ported unchanged from the original package. Every output in the lab, stress and sizing workspaces follows these definitions.
Holding months
HoldingMonths = EnteredMonths + StressDelay
Gross exit value
GrossExit = CurrentGrossValue × (1 − Depreciation)^years × (1 + PriceShock) · years = months ÷ 12
Acquisition basis
Basis = Purchase + Refurbishment + InboundTransport + ExtraRepairs
Total cash cost
CashCost = Basis + MonthlyHoldingCost × Months
Net exit proceeds
NetExit = GrossExit × (1 − SellingFee) − OutboundTransport
Operating income
OperatingIncome = MonthlyNetOperatingIncome × Months
Profit
Profit = NetExit + OperatingIncome − CashCost
Return on cash cost
ReturnOnCost = Profit ÷ CashCost × 100 · not defined when CashCost = 0
Break-even gross sale
BreakEven = max(0, (CashCost − OperatingIncome + Outbound) ÷ (1 − SellingFee))
Asset stock
Stock = UnitsInUse × CurrentValue
Annual traded units
Traded = UnitsInUse × AnnualShareResold
Annual transaction value
GMV = Traded × CompletedPrice
Platform fee revenue
FeeRevenue = GMV × TakeRate
Uncertainty corridor
GMV × (1 ± Uncertainty) · user-defined range, not a confidence interval
