It certainly costs me more than $0.16 to make a cup of coffee at home. My most recent coffee purchase was for 400g and was ~$14 (so not a super expensive brand). I use ~20g per serving, so my bag of beans gets me ~20 servings. That works out to $0.70/serving in coffee. To be fair, I drink black coffee, with no steamed milk. It's more fair to compare my at home coffee to a regular, $2.00 cup of Starbucks coffee (which is vastly inferior to my at home coffee in quality).
