(food purchases (converted to total amount) - end of the month inventory (converted to total amount))/turnover = gross profit margin.
Two, break-even point
(labor costs + rental costs + miscellaneous expenses) / gross margin equal to the monthly capital conservation break-even point. Divide the daily by 30 and you're done.
Three, net profit
(total turnover * gross margin - (labor cost + rent cost + miscellaneous expenses))/total turnover.
Thanks
