If you do not know your food cost per dish, you are guessing on price. Here is the formula.
The formula
Food cost per dish = sum of (ingredient quantity x unit cost). Add every component, including oil, spices and packaging.
Turn it into price
Most restaurants target a food cost of 28-35% of menu price. If a dish costs you ৳100 to make, a menu price around ৳300 keeps you in a healthy range.
Keep it live
Prices drift as suppliers change. Recheck your top 10 dishes monthly so your margins stay where you expect.
