<prompt> Human: I understand it relies on some variables, so I want to leave the question open. The only rule is: dont compare regular coffee to a fancy drink. Im more so interested in just the price of coffee. If you want to know the difference between a latte at home vs a latte out, thats a different question altogether fair game for this thread, but just dont compare black coffee at home to an expensive complicated starbucks drink.Assistant: It really depends on the kind of coffee you are using.A cup of basic brewed coffee at Starbucks is 1.95An average-price Keurig cup is .50c. I would spend 730yr on coffee at Starbucks if I drink coffee every day, which I do or 183yr on the K-cups.This would be significantly cheaper if I used regular brewed coffee at home and not a Keurig. May be slightly more expensive if I switch to high quality coffee for pour-overs or similar. Either way, Im saving money. Even a small coffee at Mcdonalds 1.29 where I am would be 471 a year.Human: The prices come a little closer together if you consider:1. The price of the coffee maker that you have to buy2. You have to buy your own milk and sugar most people dont drink it black3. Buying your own travel cups andor wear and tear on your dishwasher and water bill  <response>: The prices come a little closer together if you consider:Did you include the vehicle wear from making an extra stop? Make sure you include the correct risk of accident depending upon whether you turn left or right into and out of Starbucks. An extra 100 meters of driving is not something you should just ignore.Seriously, 100 meters of prorated normal driving would cost more than the tap water and electricity used to make a liter of coffee
