sscoffee,
We're small. In fact, we are the smallest successful shop in the US. So much of what we do doesn't translate to the typical shop, however, it shows that it can be done on any scale.
Let's assume monthly revenue is $1.00
An average monthly expense for us would be:
.16 rent
.15 espresso/coffee/tea (Cost of green, and all other associated COGS)
.08 Food/pastries
.08 Business Loan Payment
.08 Taxes
.07 Utilities+phone,internet, and cell.
.05 Insurance (health & property)
.05 Owner's Draw
.03 Business Travel
.03 Misc
.02 Company Car Expenses
Total $0.80
Of course month to month this varies and how cash flow figures out in the picture is important as well. We also do upgrades and improvements each year, which may fall somewhere in misc.
Many will say rent is high, (Most would say to stay around 7-10%) and it is if other expenses are as high as your typical shop... but efficiency in store design, electrical, hours of operation, and product sourcing makes "rent" just another expense. At the end of the day, you have to look at your total revenue and your total expenses. If one is high enough and the other is low enough, that's a good thing.
