Calories in an Egg: Boiled, Fried and Omelette

General information: This article is information about food data. No dietitian or doctor has reviewed it, and it is not a substitute for their advice.

Disclosure: NYUS Inc. publishes this guide and makes the NYUS app, which is mentioned once near the end. The numbers below do not depend on it.

A boiled egg with breakfast, a fried egg on toast, an omelette or an egg bhurji: the egg is the same, but the cooking changes what you log. Our other guides give the boiled egg from the Indian tables; this guide puts boiled, poached, fried, scrambled and omelette eggs side by side from five USDA FoodData Central records, using the large-egg weight USDA prints on each record, and checks the boiled egg against IFCT 2017. The figures are for the plain cooked eggs the records describe, not for an Indian omelette or bhurji made with oil, onion and chilli.

The short answer

By the USDA records below, one large egg (50 g) is about 78 kcal hard-boiled and about 72 kcal poached. A large fried egg (46 g) is about 90 kcal, a large scrambled egg (61 g) about 91 kcal and a large omelet egg (61 g) about 94 kcal. For the same 50 g, IFCT 2017's boiled egg is about 74 kcal, which is the figure our other egg pages use. Our reading: per egg the five USDA eggs run from 72 to 94 kcal; only the fried record is higher per 100 g than the boiled one (196 against 155), and that extra is fat, while the omelet and scrambled eggs are higher per egg because USDA lists them as 61 g, not because they carry more energy per 100 g. An Indian omelette or bhurji made with oil, onion and chilli is not one of these rows.

Calories per 100 g and per egg

For the boiled egg we have both an Indian and a US source. IFCT 2017 Table 1 gives the whole boiled egg (M004, 6 regions, PDF page 58) at 618 kJ per 100 g, which is 148 kcal at 4.184 kJ per kcal, and prints no weight for one egg; IFCT has no fried, omelette, scrambled or poached row that we found. The five USDA FoodData Central SR Legacy rows give the kcal per 100 g as printed on each record, and the weight of one large egg as printed on the record page: 50 g for hard-boiled and poached, 46 g for fried and 61 g for scrambled and omelet. For the IFCT row we use 50 g, the same as USDA's large boiled egg: that weight is ours, so the row is labelled that way. Your egg may be smaller or larger than USDA's large egg, so weigh it. Each figure is the grams times the kcal per 100 g in the table, divided by 100, rounded to the nearest kcal with half rounding up. The USDA fried and omelet records include the fat USDA assumed in cooking, so an omelette or bhurji made at home with a different amount of oil, with onion, tomato and chilli, is not these rows: we give no number for it, and the oil goes on top by the teaspoon.

Egg	Source	kcal per 100 g	1 egg (where the weight comes from)	kcal per egg	kcal for 2 eggs
Egg, whole, cooked, fried	USDA FDC 173423	196 kcal	1 large egg, 46 g (USDA)	90 kcal	180 kcal
Egg, whole, cooked, hard-boiled	USDA FDC 173424	155 kcal	1 large egg, 50 g (USDA)	78 kcal	155 kcal
Egg, whole, cooked, omelet	USDA FDC 172185	154 kcal	1 large egg, 61 g (USDA)	94 kcal	188 kcal
Egg, whole, cooked, scrambled	USDA FDC 172187	149 kcal	1 large egg, 61 g (USDA)	91 kcal	182 kcal
Egg, poultry, whole, boiled	IFCT 2017 M004 (Table 1, PDF page 58)	148 kcal (618 kJ)	1 egg, 50 g (weight is ours: USDA's large-egg weight; IFCT prints none)	74 kcal	148 kcal
Egg, whole, cooked, poached	USDA FDC 172186	143 kcal	1 large egg, 50 g (USDA)	72 kcal	143 kcal

What stands out in the numbers

Per 100 g the rows run from 143 to 196 kcal: fried 196, hard-boiled 155, omelet 154, scrambled 149, IFCT boiled 148 and poached 143.
Per egg the order changes. The omelet and scrambled records list a large egg as 61 g against 50 g for boiled and 46 g for fried, so an omelet egg is about 94 kcal and a fried egg about 90, though fried is the highest per 100 g.
Fat explains the fried egg. The records print fat per 100 g of 14.8 g for fried, 11.7 g for omelet, 11 g for scrambled, 10.6 g for hard-boiled and 9.47 g for poached, and IFCT prints 10.54 g for boiled; per large egg that is about 6.8 g fried, 7.1 g omelet, 6.7 g scrambled, 5.3 g hard-boiled and 4.7 g poached, by our arithmetic.
Protein per egg is close. By our arithmetic on the records a large egg has about 6.3 g of protein boiled, 6.3 fried, 6.5 omelet, 6.1 scrambled and 6.3 poached; this is food data, not a protein target.
Two sources, two boiled eggs. USDA's boiled egg is 78 kcal and IFCT's is 74 for the same 50 g, a difference of about 4.7%; see our eggs a day guide for the IFCT version.

How to log it so the numbers hold

Log the egg and the oil separately. Our spoon guide gives a level teaspoon of oil or ghee as about 41 kcal; measure what goes in the pan and add it to the egg row.
Bhurji and masala omelette. Onion, tomato, chilli, coriander, paneer or cheese are extra and are not in these rows; weigh them and log them by their own rows.
Weigh the egg when it matters. An egg may be smaller or larger than USDA's large egg; peel and weigh a boiled one once and scale from the per 100 g column.
Do not mix sources inside one day. If you log boiled eggs from the IFCT figure elsewhere, keep to it; the USDA figure is about 4.7% higher.

Where NYUS fits (our app)

We make NYUS, so read this as ours. NYUS is an AI fitness and nutrition coach in early access on Android, with no ads and no data selling. You log foods yourself by searching 8,900+ Indian and global foods or by barcode, and a weekly check-in adjusts your calories, macros and step goal once enough is logged. Barcode coverage of Indian packaged foods is not complete, so search by name when a scan finds nothing.

What this page leaves out

A calorie or protein target: we have not looked up one for any person, so we give none.
Egg curry, egg bhurji, masala omelette, bread omelette, egg rolls, egg fried rice and any dish with egg in it, and the raw egg, egg white and yolk rows: not covered here (our protein guides use the IFCT egg rows).
Duck, quail and other eggs, and eggs of a different size: not covered here.
Brand pack labels and FSSAI figures: not used, so the page does not mix label numbers with the records above.
Anything about weight, health or what eggs do to your body: the page adds up food data and makes no claim about it. If you have a medical condition, ask your doctor or dietitian.

The 50 g weight for the IFCT row, the sums, the rounding, the kilojoule to kcal conversion, the per egg protein and fat, the percentage difference between the two boiled-egg sources and every sentence starting "Our reading" are NYUS's own arithmetic or opinion, not from USDA or IFCT. The large-egg weights in the table are USDA's, printed on the record pages above. Names in the Egg column (boiled, fried, omelette, scrambled, poached) are our matching to the record names listed above.

Frequently asked questions

How many calories are in one boiled egg?

The USDA FoodData Central SR Legacy record 173424 (Egg, whole, cooked, hard-boiled) prints 155 kcal per 100 g and lists 1 large egg as 50 g, so one boiled egg is about 78 kcal by our arithmetic and two about 155 kcal. IFCT 2017 M004 (Egg, poultry, whole, boiled) prints 618 kJ per 100 g, which is 148 kcal at 4.184 kJ per kcal, and for the same 50 g (our assumption) that is about 74 kcal. The two sources differ by about 4.7%. Your egg may be smaller or larger than USDA's large egg: weigh it.

How many calories are in a fried egg compared with a boiled egg?

USDA SR Legacy 173423 (Egg, whole, cooked, fried) prints 196 kcal and 14.8 g of fat per 100 g against 155 kcal and 10.6 g for the hard-boiled record, and lists 1 large fried egg as 46 g, about 90 kcal against about 78 for the boiled egg by our arithmetic. The extra is the fat in the fried record, which USDA assumed; the oil you use will change it.

How many calories are in an omelette or egg bhurji?

USDA SR Legacy 172185 (Egg, whole, cooked, omelet) prints 154 kcal per 100 g and lists 1 large egg as 61 g, about 94 kcal, and 172187 (Egg, whole, cooked, scrambled) prints 149 kcal and the same 61 g, about 91 kcal, by our arithmetic. An Indian omelette or bhurji with oil, onion, tomato and chilli is not these rows, and we give no number for it: add the oil by the teaspoon (our spoon guide gives a level teaspoon of oil or ghee as about 41 kcal) and the vegetables by weight.

How many calories are in a poached egg and in two eggs?

USDA SR Legacy 172186 (Egg, whole, cooked, poached) prints 143 kcal per 100 g and lists 1 large egg as 50 g, about 72 kcal, and two poached eggs are about 143 kcal. Two eggs by our arithmetic: boiled about 155 kcal, fried 180, omelette 188, scrambled 182.

Why do other NYUS pages say 74 kcal for a boiled egg and USDA says 78?

They use different sources for the same 50 g. IFCT 2017 M004 prints 148 kcal per 100 g, so 50 g is 74 kcal; USDA 173424 prints 155 kcal per 100 g, so 50 g is 78 kcal. Both are food-table values, the difference is about 4.7%, and neither is the energy of your own egg.

Can I log an egg or an omelette in NYUS?

NYUS is our app. You log foods yourself by searching 8,900+ Indian and global foods or by barcode; log the egg and the oil separately for the best match.
