Don't forget the cost of operating the truck. Instead of figuring the cost of gas, and tires, insurance, maintenance, I will use the average payment to a person using their own car for an employer. Specialty and therapeutic shoes, hot forging, all add additional costs. A farrier can usually trim three horses in the same time needed to shoe one horse. If this is a true business, we have only talked about expenses and not about the business making a profit .
Any business owner wants to make a profit on the money they have put into the business.
One thing you will need to remember - other items do run up the cost of shoeing and trimming. If you are a long way out, he or she has a lot of travel time, and possibly overnight expenses. Or, if your horse has a problem about standing quietly for the farrier and it takes longer to shoe or trim, the farrier cannot complete as much work. Time is money to your farrier. Also, think about the quality of the farrier's work.
