How to Calculate the True Cost of Every Dish on Your Menu

A Step-by-Step Recipe Costing Guide for Indian Restaurant Owners — Covering Yield Percentage, the Q Factor, Cooking Shrinkage, Batch Costing for Gravies, Packaging Costs, and Four Fully-Worked Dish Examples Including Butter Chicken, Biryani, Masala Dosa, and Mango Lassi

Most Indian restaurant owners know approximately what their food costs as a percentage of revenue — and most of them are wrong. The figure they hold in their heads is typically derived from supplier bills divided by monthly revenue, which measures what was purchased, not what each dish actually cost to produce. The difference matters because purchased cost and true dish cost diverge in three systematic ways: yield loss (the gap between what you buy and what you actually use after trimming, butchering, and cooking), invisible costs (oil, spices, gas, salt, garnish — the Q Factor), and production overheads (packaging, portioning waste, mis-fires). This guide provides a complete, practical methodology for calculating the true cost of every dish on an Indian restaurant menu — with four fully-worked examples across dish categories — and shows how to use those costs to set prices that are both competitive and profitable. Restaurant owners who complete this exercise typically discover that 30–40% of their menu items are priced 15–25% below their true cost — and that this gap, not the economy or the competition, is the primary driver of their margin problem.

1. Why Most Indian Restaurants Don't Know What Their Dishes Actually Cost

Ask the owner of a mid-size Indian restaurant what their Butter Chicken costs to make and most will give you a confident number: 'About ₹150 per plate.' Ask them how they arrived at that figure and the answer almost always comes down to the same method: they know they spend roughly ₹35–40 per kg on chicken, use about 200g per portion, so the chicken alone is ₹7–8; the rest of the ingredients are estimated at ₹120–140 from memory. The number feels about right. The problem is that it is not right — and the gap between 'feels right' and 'actually right' is where restaurant margins disappear.
