If you want to calculate labor cost you have to Divide labor cost by total operating costs. For example if labor costs $9,000 per month and total operating cost is $15,000 per month, divide $9,000 by $15,000 to get 0.6. Multiply by 100. This final number is your restaurant's labor cost percentage. In this example, it's 60% of the total cost of doing business.
It all depends
