The physical calculation for cost of carry is two parameters and the unit of measure and value of the contractcan be found below:
(Current Futures Price * (Days/365) * IR%) + ((Days/365) * 12 * Monthy Storage * 100)
Market Carry is the difference between the nearer term futures contract and the farther term futures contract (ZCU22 - ZCZ22).
% of Full Carry is the percentage of the costs of carry that the market carry covers (Market Carry/Cost of Carry)
By default, the panel is set to use Corn as the commodity. You can change the underlying commodity contract by clicking on the dropdown menu in the upper right corner. Commodities covered in the Cost of Carry include corn, soybeans, wheat (CBOT), spring wheat (MGEX), hard red wheat (KCBT), canola (ICE/CA), barley and oats (CBOT).

For example, corn trades in bushels. The storage cost per bushel is something like $.0025 (i.e. 1/4 cent) per bushel per day. So the storage cost for corn, from September to December, is $.0025 x 3 months x 30 days/month = 22.5 cents (leave it in cents for grains, not dollars. i.e. not .225)
