How to Use This Calculator
  1. Enter the Near-Month Futures price and the Deferred (later) Futures price.
  2. Enter Months Between the two contract months.
  3. Enter Storage Cost per bushel per month and your current Interest Rate.
  4. Review Carry Per Bushel (the futures spread) and Total Carry Cost.
  5. Check Net Return Per Bushel and % of Full Carry to decide whether storing grain is profitable.

What each input means

Near-month futures ($/bu)
Near-month futures contract price.
Deferred futures ($/bu)
Deferred (later) futures contract price.
Months between
Months between the two contract months.
Storage ($/bu/mo)
Monthly storage cost per bushel.
Interest rate (%)
Annual interest rate for opportunity cost.

What each result means

Carry ($/bu)
Futures spread (deferred minus near).
Total carry cost ($/bu)
Storage plus interest cost per bushel.
Net return ($/bu)
Carry minus carry cost (positive = profitable storage).
% of full carry
Market carry as percentage of full carry cost.
Storage cost ($/bu)
Total storage cost for the period.
Interest cost ($/bu)
Opportunity cost of capital.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Near-month futures ($/bu) = 5.8, Deferred futures ($/bu) = 6.1, Months between = 4, Storage ($/bu/mo) = 0.04 = 5 input(s) provided
  2. Calculate Carry
    Carry = round((deferredFutures - nearMonthFutures) * 10000) / 10000
    0.3 = 0.3
  3. Calculate Total carry cost
    Total carry cost = round((storageCost + interestCost) * 10000) / 10000
    0.2953 = 0.2953
  4. Calculate Net return
    Net return = round((carry - totalCarryCost) * 10000) / 10000
    0.0047 = 0.0047
