How Much Cooking Oil per Day, per Person and per Family (2026)

Last updated: 30 September 2026

> Quick Answer: How much oil per day depends on activity: ICMR-NIN puts cooking oil at 20 to 50 g per person, or 4 to 10 teaspoons. About 27 to 30 g suits a typical 2,000 kcal diet. That is roughly 1 litre a month for one person and 3.5 to 4 litres for four.

Search the question and you'll find answers anywhere from 2 to 7 teaspoons, mostly from forums and opinion pieces. There is a sourced figure, though. The ICMR-National Institute of Nutrition's Dietary Guidelines for Indians, revised in 2024, give a range per person per day tied to how active you are, and it covers every visible fat, not only the oil bottle.

That last point is the one most households miss. The limit includes the ghee on the roti and the butter on the toast, so a family that measures its oil carefully and adds ghee freely is over it without noticing.

What do ICMR-NIN and FSSAI actually recommend?

ICMR-NIN limits visible fat, meaning cooking oil, ghee and butter, to 20 to 50 g per person per day by energy need. Sedentary adult women are advised 20 g and men 30 g; moderately and heavily active women up to 30 and 40 g, and men up to 40 and 50 g. FSSAI's 2025 campaign asks for a 10% cut.

Those figures are on page 54 of the ICMR-NIN Dietary Guidelines for Indians 2024, which add that not more than 27 to 30 g is required on a 2,000 kcal diet. FSSAI, the food regulator, launched its "Stop Obesity" campaign on World Food Safety Day, 7 June 2025, calling for a nationwide 10% reduction in salt and oil, as recorded in a Press Information Bureau note on Eat Right India. Its "Aaj Se Thoda Kam" message asks for gradual cuts in fat, sugar and salt.

Teaspoons, grams and millilitres, how do they convert?

One teaspoon of oil is about 5 g, a tablespoon about 15 g, and 5 g of oil is about 5.5 ml. ICMR-NIN's own conversion, 20 to 50 g as 4 to 10 teaspoons, uses the 5 g teaspoon. A 30 g day is six teaspoons, or two tablespoons, or about 33 ml.

Millilitres and grams don't match because oil is lighter than water. The Codex standard for named vegetable oils puts mustardseed oil at a relative density of 0.910 to 0.921, so a litre weighs about 910 g; the full conversion is on the mustard oil litre to kg page.

• 20 g a day: 4 teaspoons, about 600 g or 0.66 litre a month.
• 30 g a day: 6 teaspoons, about 900 g or 1 litre a month.
• 50 g a day: 10 teaspoons, about 1.5 kg or 1.65 litres a month.

How much oil does a family of four use in a month?

At ICMR-NIN's 27 to 30 g per adult on a 2,000 kcal diet, four adults use 108 to 120 g a day. Over a 30-day month that is 3.2 to 3.6 kg, or roughly 3.5 to 4 litres. A household of two sedentary adults and two younger children will need less.

The simplest check: write down the date a new bottle is opened and the date it runs out. A 1 litre bottle lasting a week in a family of four means close to 130 g a day, above the guideline range for four adults, even before ghee is counted.

Where does the hidden oil go?

Mostly into deep frying, second tadkas, pickles and shop-bought snacks. Deep-fried pakoras and puris absorb oil in the kadhai, a tadka poured over finished dal adds a spoonful on top of the cooking oil, and achar sits in oil by design. Namkeen, biscuits and restaurant meals carry fat the kitchen bottle never sees.

The ICMR-NIN guidelines separate this visible fat from the invisible fat already inside foods such as nuts, cereals and pulses. The limit applies to what you add, but bought food eats into it too. The WHO healthy diet fact sheet points the same way: total fat at 30% or less of daily energy, and steaming or boiling instead of frying to reduce it.

Does the type of oil change the limit?

No. The limit is on total visible fat, and every oil and fat carries about 9 kcal per gram, as ICMR-NIN notes. Mustard, groundnut, sunflower, ghee and butter all count against the same 20 to 50 g. Choosing one oil over another changes the fat profile, not the quantity you can use.

What the oil does change is how much you need for flavour. Pungent black mustard oil flavours a tadka or pickle in small amounts, and yellow mustard oil is milder for everyday sabzi. Per-spoon calorie figures are on the mustard oil calories page, and cooking methods that use less oil on how to cook with mustard oil.

1 litre or 5 litre, which pack fits your month?

A 1 litre pack fits one person for about a month at 30 g a day; a 5 litre pack fits a family of four for about five to six weeks. Buy the size you will finish within a couple of months, since opened oil slowly loses freshness. Per litre, the 5 litre packs work out slightly cheaper.

On 30 September 2026, SatRas black mustard oil sold at ₹304 for 1 litre, down from ₹689, and ₹1,450 for 5 litres, down from ₹1,500, which is ₹290 per litre. Yellow mustard oil sold at ₹449 for 1 litre, down from ₹879, and ₹2,000 for 5 litres, down from ₹2,050, which is ₹400 per litre.

For a single person, the 1 litre pack is the one that matches the ICMR-NIN month. For four people, one 5 litre pack plus ghee used sparingly lands close to the guideline range.

What does the daily figure not tell you?

It's a population guideline for healthy adults, not a personal prescription. ICMR-NIN scales it by activity and notes different needs in pregnancy and lactation, and it covers quantity only. It does not settle which oil suits a given person, and it says nothing about individual medical conditions.

Quantity is also not the only question asked about mustard oil. Its erucic acid content varies with the seed variety, and that is a separate subject, covered on the mustard oil erucic acid page. The FSSAI 10% figure is a nudge to reduce from wherever a household is now, not a target in grams.

This article is educational and is not medical advice. Anyone managing a medical condition or a prescribed diet should speak to a qualified doctor or registered dietitian before changing their fat intake.

What should you avoid when cutting oil?

Avoid measuring only the oil bottle, cutting oil to near zero, and reusing deep-frying oil again and again. Also avoid switching oils in the belief that a different oil can be used more freely. Each one either undercounts the fat or swaps one problem for another.

• Ignoring ghee and butter. They count in the same limit.
• Pouring from the bottle. Use a teaspoon until the habit settles.
• Reheating frying oil repeatedly. Keep deep frying occasional.

Frequently asked questions

Is 1 litre of oil a month per person too much?

Not for most adults. A litre is about 910 g, or roughly 30 g a day over a month, which sits inside ICMR-NIN's 20 to 50 g range and matches its figure for a 2,000 kcal diet. It is on the high side for a sedentary adult woman, whose guideline is 20 g, especially if ghee is also used.

How do I measure oil without a spoon?

Track the bottle instead of the pan. Note the date you open a new litre and when it runs out, then divide by the number of people and days. For daily cooking, pour into a small steel katori marked at a known amount first, rather than straight from the bottle into the kadhai.

Does ghee count towards the daily oil limit?

Yes. ICMR-NIN counts cooking oils, butter and ghee together as visible fat, and the 20 to 50 g range covers all of them. A teaspoon of ghee on a roti uses the same share of the day's limit as a teaspoon of oil in the dal.

How many calories are in a teaspoon of cooking oil?

About 45 kcal. A teaspoon holds roughly 5 g of oil, and every oil and fat provides about 9 kcal per gram. Six teaspoons, a typical 30 g day, come to around 270 kcal. The figure is the same for mustard, groundnut, sunflower and other cooking oils.

Is the ICMR limit per person or per household?

Per person, per day. The 20 to 50 g range is set for one individual according to their activity level, so a household total is the sum of each member's figure. Children, older adults and people with very different activity levels will each sit at a different point in the range.

Can food be cooked with almost no oil?

Yes, and ICMR-NIN notes that essential fatty acid needs can be met from nuts, oilseeds, pulses and beans without visible fat. In practice most Indian cooking uses some oil, so the guideline limits it rather than removing it. Steaming, boiling and dry roasting all reduce the amount needed.
