The price (net price) of the converted treasury bonds can be obtained by multiplying the conversion coefficient of the deliverable treasury bonds by the settlement price of futures delivery, and the actual cash price (full price) that the seller should get when transferring the deliverable treasury bonds at futures delivery can be obtained by adding the accrued interest income during the period of holding the treasury bonds to the net price of the treasury bonds. This price is the transfer price of deliverable treasury bonds, also known as the floor price.

The calculation formula is as follows: invoice price = settlement price of treasury bond futures delivery x conversion coefficient+accrued interest.
