I got the urge to make a burger at home rather than get a takeout burger and it was absolutely delicious and asweetpeachef.com. I pulled up my store receipt to figure out the cost of the burger and found the burger ultimately cost me $4.81. I've listed the prices below; they go to so many digits because something like the hamburger buns were bought in a pack of 12 for $2.79 but I only used 1. Same with a jar of pickles, burger sauce, etc. The lettuce, purple onions, and tomatoes came packaged together as "hamburger fixins."
Meat $2.445 Cheese $0.9975 Bun $0.2325 Fixins $0.8725 Pickles $0.1195 Burger sauce $0.143125
Total $4.810125


So your labor in buying the fixings, transporting the fixings and preparing the fixings has no value? Good to know. Also, cheese did not cost you a dollar, it cost a penny. And, if you only made one burger, then the total cost of all the ingredients (12 buns, the entire jar) is your actual cost, not the individual serving.
Do yourself a favor and never open a restaurant or contracting business. I shudder to think how quickly that would go bankrupt.
