I put this reload cost calculator together a few years ago, it is a little complicated at first so I've protected the cells to prevent inadvertent deletions.
Instructions;
-Enter values in the pink cells
-Enter buy cost for your projectiles & powder & primers & cases
-Enter buy cost for the quantity of component purchased
-Projectile units must be one of either number or mass(kg) or mass (lb) [usually number of projs]
-$per is the buy cost for the amount of either projectiles or powder.
-Break down of component unit costs provided as well as final cost per loaded round in red cells.
-Cost per round option provided with 1 or 4 or 8 uses of brass with last column option to enter any re-use quantity (15 entered)
-Any questions or suggested mods please feed back else get loading!
