How Many Calories in a Bar of Snickers?
Peanuts have given Snickers a half-earned reputation as the sensible chocolate bar. The numbers: a standard 48 g bar is 235 calories, and per 100 g Snickers comes to 489 kcal with 51.8 g of sugar. That's the plain answer to how many calories in a bar of snickers — mid-table chocolate, whatever the peanuts imply.
You'd need to walk about 47 minutes to burn the 235 calories in a standard 48 g bar.

Bar, Duo, fun size
The wrapper format decides the damage more than the recipe does:
- Standard bar, 48 g: 235 kcal
- Snickers Duo, 2 × 41.7 g: 408 kcal for the pack, 204 per bar
- Fun size: about half a standard bar, so in the region of 115–120 kcal depending on the weight printed on the pack
The Duo deserves its own sentence. Each half is smaller than a standard bar, which feels like restraint, but almost nobody buys a Duo to eat one half. Eaten as sold, it's 408 calories — nearly double the standard bar, packaged to feel like the same purchase.
If the meal deal only offers the Duo, there is a workable move: eat one bar at 204 kcal and bank the other for tomorrow. It only counts if the second bar actually survives the afternoon.
The protein question
The peanuts do show up in the numbers: 8.6 g of protein per 100 g makes Snickers about the most protein-dense of the classic chocolate bars. Then the portion maths deflates it. A 48 g bar delivers just over 4 g of protein, alongside 24.9 g of sugar.
So no, it is not a protein bar, and it isn't halfway to one. Four grams is what the label calls a start; the sugar column is where the bar actually lives. The peanut halo is the single most persistent myth about this bar, and one glance at the per-bar figures retires it.
For calibration: the daily reference intake for protein is 50 g. One bar covers 8% of that while covering 28% of the sugar allowance. That ratio, not the peanuts on the wrapper, is the honest description of what you're eating.

Where the sugar sits
More than half of a Snickers by weight is sugar: 51.8 g per 100 g, 24.9 g in a standard bar. That single bar covers 28% of the 90 g daily reference intake for total sugars, and all of it counts as free sugars — the kind the WHO advises keeping well down.
The fat side is calmer than you might guess: 11.5 g per bar, 16% of the reference intake. Salt is a rounding error at 0.30 g. On a calorie tracker, a Snickers is fundamentally a sugar entry with a peanut accent.
The wrapper also shows 983 kJ next to the 235 kcal. Same energy, different unit; UK labels carry both, and it's the kilojoule figure that startles people who haven't seen it before.
Logging a Snickers properly
The standard bar is the easy log: 235 kcal, one tap, done. The traps are the non-standard formats. Fun size and multipack bars use different weights from the single, and those weights have shifted over the years, so scale from 489 kcal per 100 g and the grams printed on the wrapper rather than trusting an old database entry.
A Duo is two entries, or one honest 408 kcal entry — never "a Snickers". And the spin-offs (ice cream bars, cake bars, protein-branded versions) are different products with their own labels; none of them inherit the single bar's numbers.
How does a Snickers compare?
| Bar | Portion | Calories |
|---|---|---|
| Twirl | twin bar | 228 kcal |
| Snickers | standard bar | 235 kcal |
| Kinder Bueno | one bar | 245 kcal |
| Twix | twin bar | 246 kcal |
| Bounty | twin pack | 278 kcal |
Verdict: the whole shelf sits inside a 50-calorie band, so switching bars is not a weight-loss strategy — picking a format is. Snickers is a fair middle pick that at least brings some protein; the real decision is standard bar versus Duo, a 173-calorie difference in the same wrapper design. For something genuinely small, a single Malteser is a different scale of snack altogether.

Ranked by how widely each product appears among foods sold in the United Kingdom, from the BodyPal food database of over 3.3 million products. Calories are the figures printed on each label. The ice cream version is lighter per 100 g because ice cream replaces nougat — not because it is a diet product.

FAQ
How many calories are in a Snickers bar in the UK?
235 calories in the standard 48 g single bar, from the UK label figure of 489 kcal per 100 g. That places it mid-pack among UK chocolate bars: a little above a Twirl twin, a little below a Twix.
How many calories are in a fun size Snickers?
Roughly half a standard bar — in the region of 115–120 calories, depending on the exact weight printed on the pack, since fun size weights have shifted over the years. Check the multipack label for the current gram figure and scale from 489 kcal per 100 g.
How many calories are in a Snickers Duo?
408 calories for the whole Duo pack of two 41.7 g bars, or 204 per bar. Eating both halves — which is how Duos are eaten — costs 173 kcal more than a standard single, making the Duo the most expensive routine choice on the Snickers shelf.
Is Snickers a protein bar?
No. A standard bar carries just over 4 g of protein next to 24.9 g of sugar. The 8.6 g per 100 g is high for classic confectionery, but an actual protein product delivers several times that per serving with a fraction of the sugar.
How much sugar is in a Snickers?
24.9 g in a standard 48 g bar, from 51.8 g per 100 g — more than half the bar's weight is sugar. One bar covers 28% of the 90 g daily reference intake for total sugars, all of it as free sugars.
Is Snickers suitable for vegetarians?
It contains milk ingredients, so it is not vegan, and vegetarian status depends on the current ingredient list, which changes between markets and over time. The wrapper is the reliable source: UK packs state clearly when a product is registered as vegetarian.
How many calories are in 100 g of Snickers?
489 kcal per 100 g on the UK label, with 8.6 g protein, 60.5 g carbohydrate and 23.9 g fat. Weight for weight that is chocolate-bar standard: the peanuts swap a little sugar for fat and protein without changing the calorie total much.
Snickers or Twix: which has fewer calories?
Snickers, narrowly: 235 calories for the standard bar against 246 for a Twix twin. An 11-calorie gap is noise in a day's eating, so choose on preference; the Snickers does bring roughly twice the protein along with it.
