Calories in 1 Apple, Banana, Orange and Guava

By NYUS Inc. · Published 27 October 2026

"How many calories in one apple?" "Is a banana more than a mango?" Fruit calories are usually given per 100 g, but fruit is eaten by the piece, the slice or the katori. This guide gives the calories, protein, fat, fibre and carbohydrate per 100 g for twelve fruits from the ICMR-NIN Indian Food Composition Tables 2017 (IFCT 2017), then turns them into one medium apple, one banana, one orange and the rest using weights that are ours.

The short answer

By IFCT 2017, the twelve rows run from 20 kcal per 100 g (watermelon, E065) to 105 kcal per 100 g (banana, E012). By our arithmetic, one medium apple of about 150 g is about 94 kcal, one medium banana of about 100 g peeled is 105 kcal, one medium orange of about 130 g pulp is 48 kcal, one medium guava of about 100 g is 32 kcal and a medium mango of about 150 g pulp is 63 kcal. Our reading: an apple and a banana are within about 11 kcal of each other as pieces, even though the banana has about 1.7 times the calories per gram, because the apple is a bigger piece.

Calories, protein, fat, fibre and carbohydrate per 100 g

Each row is one IFCT 2017 Table 1 row, per 100 g edible portion as listed in the book, mean values as printed. Energy is the book's kilojoules divided by 4.184, to the nearest kcal. Fibre is total dietary fibre and carbohydrate is the book's available carbohydrate. Every row was measured in 5 or 6 regions. The values are for the raw, ripe fruit.

Per piece, slice or katori

The weights are ours, not from IFCT: they are grams of edible portion, after peeling and removing seeds, stones and core, for a medium fruit. A medium apple is about 150 g, a banana 100 g peeled, an orange 130 g of pulp, a guava 100 g, a mango 150 g of pulp, a papaya slice 150 g, a small katori of pomegranate seeds 100 g, a pear 150 g, a chikoo 100 g, a watermelon slice 200 g, a pineapple slice 80 g and 10 grapes 50 g. Real fruit ranges from about half to double those weights, so weigh yours. Each figure is the per-100 g value times the grams, divided by 100, rounded to the nearest kcal and 0.1 g; the 2 servings column is doubled before rounding, so it can differ by 1 kcal from twice the rounded figure.

What stands out in the numbers

• Banana and chikoo are the densest per gram: 105 and 73 kcal per 100 g, against 20 kcal for watermelon and 24 kcal for papaya. Our banana guide covers the banana in more detail, but it uses common-size figures, not this row: about 90 kcal for a small banana of about 100 g and 105 to 110 kcal for a medium one of about 118 g. IFCT row E012 is the robusta variety and gives 105 kcal per 100 g peeled, so the two pages differ for the same weight; neither is wrong, they are different sources and varieties.
• Per piece the order shuffles. One apple (94 kcal) is close to one banana (105 kcal); a chikoo is 73 kcal; a pear is 56 kcal; a whole watermelon slice of 200 g is only about 41 kcal because it is mostly water.
• Guava and chikoo carry the most fibre per piece: about 8.6 g in a 100 g guava and 9.6 g in a 100 g chikoo by our weights, against about 6.7 g in a 150 g pear. IFCT lists 8.59 g and 9.60 g of fibre per 100 g for those two rows.
• A mango pulp serving is modest per piece by this row: row E036 (banganapalli) gives 42 kcal per 100 g, so 150 g of pulp is about 63 kcal. Other varieties differ; see our mango varieties guide.

How to log it so the numbers hold

• Weigh the edible part. The rows are per 100 g edible portion: peel the banana and orange, take out the apple core, pear core and mango stone before weighing.
• Juice, shakes and cut-fruit chaat are not these rows. Fruit juice, a banana shake with milk and sugar, or chaat masala and sugar on cut fruit change the numbers; log what goes in. If you cannot weigh, the plate method in our hand-portion guide helps.
• Unripe, dried and tinned fruit are not these rows. Raw banana, dried fruit and canned fruit have their own values; see our sugar in fruits guide for the sugar split of the fruits it covers.
• Less common fruits. Custard apple, avocado, cherries, bael and peach are in our lesser fruits guide.

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.
• Other fruits in IFCT 2017 and other varieties of the fruits above (other apples, bananas and mangoes), and any juice, shake, dried or canned fruit: this page covers the twelve rows above only.
• Anything about weight, health or what fruit does 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.
