How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersNear-month futures ($/bu) = 5.8, Deferred futures ($/bu) = 6.1, Months between = 4, Storage ($/bu/mo) = 0.04 = 5 input(s) provided
- Calculate CarryCarry = round((deferredFutures - nearMonthFutures) * 10000) / 100000.3 = 0.3
- Calculate Total carry costTotal carry cost = round((storageCost + interestCost) * 10000) / 100000.2953 = 0.2953
- Calculate Net returnNet return = round((carry - totalCarryCost) * 10000) / 100000.0047 = 0.0047
