What Is Food Wastage?
Food wastage is food that was fit to eat but ended up thrown away, whether it spoiled in storage, was cut off during prep or was left on the plate.
In an Indian restaurant it is rarely one big loss. It is a little every day: a tray of paneer past its shelf life, a vat of gravy made for a crowd that never came, half a thali sent back. The festive weeks around Diwali, which falls on 8 November in 2026, tend to make it worse, because kitchens cook ahead for demand they can only guess.
Where Food Wastage Happens
Most of it falls into three places, and each has a different cause:
| Stage | What gets thrown | Usual cause |
|---|---|---|
| Storage | Spoiled or expired stock | Over-ordering, poor rotation |
| Prep | Edible trim, burnt or surplus batches | Cooking ahead of real orders |
| Plate | Leftovers from guests | Portions bigger than appetite |
The three need different fixes, which is why a single “waste” figure tells you little. Storage waste is a buying and rotation problem. Prep waste is a forecasting problem. Plate waste is usually a menu and portion problem.
Food loss is a related term for food lost earlier, on the farm, in transport or in processing, before it reaches a shop or kitchen.
How to Measure Food Wastage
One formula covers most kitchens:
Food wastage % = value of food wasted / value of food purchased x 100
Measure it in rupees, not kilos, because a kilo of saffron rice and a kilo of onions are not the same loss. A simple log works:
- Record each item as it goes in the bin, with its value and its stage.
- Keep it going for at least a week, so one odd day does not skew it.
- Total the three stages separately to see which one drives the figure.
Our food waste cost calculator does the arithmetic once you have the log.
We have not found an official Indian benchmark for an acceptable figure in restaurants. The useful comparison is your own kitchen against its last log.
Food Wastage Example
A thali restaurant in Kota’s Gumanpura keeps a waste log for one week in October 2026, when purchases came to Rs.1,86,400.
| Stage | Value wasted | Main item |
|---|---|---|
| Storage | Rs.3,240 | Paneer and curd |
| Prep | Rs.5,860 | Dal and sabzi cooked ahead |
| Plate | Rs.4,130 | Rice and rotis |
| Total | Rs.13,230 | About 7.1% of purchases |
Note: this is an invented example for illustration only. The restaurant and figures are not real.
Prep is the largest line, and the cause is visible in the log: dal and sabzi for the evening thali are cooked in one batch at 5 pm, and on slow nights a third of it goes. Cooking in two smaller batches, the second only once the first is moving, costs nothing at all.
What the Rules Say
Two Indian rules touch food wastage directly, and neither is about penalties for throwing food away.
The first is donation. FSSAI’s Recovery and Distribution of Surplus Food Regulations, 2019 exist, in FSSAI’s own words, to protect organisations and individuals who donate food in good faith and to encourage donation to those in need. Safe surplus, handed over well before it expires, can go to a food bank instead of the bin.
The second is GST. Section 17(5)(h) of the CGST Act blocks input tax credit on goods destroyed, written off or given away, so a retailer who claimed credit on packaged food that later expires has to reverse it when the stock is written off, and donating it instead does not avoid that.
But a standalone restaurant that pays GST without input tax credit has nothing to reverse, though a hotel restaurant on the credit route does.
See Where Food Wastage Hides
Waste you never record looks exactly like stock that was stolen.
Restaurant inventory software such as Petpooja POSS deducts stock as each dish sells, using the recipe you upload for it. A physical count that comes in lower than the stock the system expects is the first sign of waste or loss, and the waste log tells you which. Inventory features vary between POS versions, so check what your plan includes.

Frequently Asked Questions
Yes, if the food is still safe and has not been served. Plated food that comes back from a guest is best kept out of it.
No, if the food is eaten. Staff meals are consumption, so log them separately, or they will hide real wastage inside the stock gap.
Both, but the restaurant controls more of it than it thinks. Portion size, unordered extras such as a free second helping of rice, and dishes that sound bigger on the menu than they turn out on the plate all shape what comes back.
A full week’s log every quarter is enough for most outlets, plus an extra one around festivals and menu changes. A daily log for the first month finds the pattern fastest.
