How Many Calories in a Twix? 123 per Finger, 246 per Bar
There are 246 calories in a standard 50 g Twix and 123 in each finger, with the label reading 493 kcal per 100 g. The twin format is the most honest thing about it: the wrapper hands you a stopping point halfway through, and almost nobody takes it.
You'd need to walk about 49 minutes to burn the 246 calories in a 50 g twin bar.

Two lines carry the story. The 24 g of sugars in one twin pack is four fifths of the 30 g of free sugars the NHS suggests an adult stays under in a whole day. And the 7 g of saturates is over a third of the daily reference, from something eaten in four bites.
The salt line, for once, is boring. At 0.20 g per bar it barely registers, which is not something the biscuit aisle can usually say.
Finger, twin and Xtra: the sizes
| Format | Weight | Calories |
|---|---|---|
| One finger | 25 g | 123 kcal |
| Twin bar | 50 g | 246 kcal |
| Twix Xtra, one stick | 37.5 g | 185 kcal |
| Twix Xtra, full pack | 75 g | 370 kcal |
The finger is the number worth memorising. At 123 kcal it is a genuinely middling snack, in the same territory as a buttered slice of toast, and the perforation between you and the second one is the cheapest portion control in the shop.
The Xtra is where the arithmetic quietly moves against you. One stick reads 185, which sounds like a modest step up from 123, but the pack is two sticks: 370 kcal, half as much again as a standard twin. Buying Xtra because it feels like better value is paying less per calorie for calories you were not planning to have.
Fifty per cent more chocolate is only a bargain if the bar was underfeeding you. It was not.
What the biscuit changes
A Twix is shortbread and caramel under milk chocolate, and the biscuit does something mildly interesting to the numbers. Plain milk chocolate runs 519 kcal per 100 g with 56 g of sugars on the CoFID figures; a Twix runs 493 with 48 g. The biscuit is the least sugary thing in the wrapper, so it dilutes the sugar concentration while keeping the fat almost level.
CoFID's generic entry for a chocolate-covered caramel and cereal bar lands at 501 kcal per 100 g, within two per cent of the Twix label. Whatever brand of caramel-biscuit bar is in your hand, you can log it at roughly the same rate and the label will not surprise you.
What the biscuit does not do is make the bar light. Per 100 g, a Twix and a Bounty are five calories apart.
Twix against the other bars
| Bar | Per item | Per 100 g |
|---|---|---|
| Twix twin (50 g) | 246 kcal | 493 kcal |
| Bounty twin (57 g) | 278 kcal | 488 kcal |
| Kinder Bueno (43 g) | 245 kcal | 571 kcal |
| Twirl twin (43 g) | 228 kcal | 530 kcal |
| Maltesers, a dozen (24 g) | 121 kcal | 503 kcal |
The verdict: per 100 g the caramel bars are actually the gentle end of the aisle, and the "light" textures, whipped and wafer, are the dense end. But nobody eats 100 g; they eat wrappers. Per wrapper the pack weight decides everything: a Twix at 246 and a Bueno at 245 are the same event, a Twirl saves you 18 on format alone. If you want the smallest honest serving of chocolate here, one Twix finger at 123, or counting out Maltesers, beats the whole table. A mug of hot chocolate plays in the same range and takes ten times longer to finish.
For context on where 246 kcal sits in a day, the NHS guide to understanding calories puts an adult's reference intake at 2,000 kcal: one twin bar is an eighth of it.

Frequently asked questions
How many calories are in one Twix finger?
One finger is 123 kcal at 25 g. That is half the standard twin pack, and the wrapper's perforation makes it a natural stopping point. Wrap the second finger back up before you start the first and the odds of it surviving improve noticeably.
How many calories in a whole Twix twin bar?
A standard 50 g twin pack is 246 kcal, with 24 g of sugars and 7 g of saturated fat. That is about an eighth of an average adult's 2,000 kcal reference intake, eaten in a few minutes. Per 100 g the figure is 493 kcal.
How many calories in a Twix Xtra?
One Xtra stick is 185 kcal at 37.5 g, and the full pack of two is 370 kcal. That is 50% more than a standard twin bar, which is the entire point of the format. If you buy Xtra, price the pack at 370, not the stick at 185.
How much sugar is in a Twix?
A twin bar carries 24 g of sugars, which is 80% of the 30 g of free sugars the NHS suggests as a daily ceiling for adults. Per 100 g a Twix holds 48 g of sugar, slightly less than plain milk chocolate because the shortbread dilutes it.
Is a Twix better or worse than a Bounty?
Per 100 g they are nearly identical, 493 against 488 kcal. The differences are format and fat type: a Bounty pack weighs 57 g so it costs 278 kcal to a Twix's 246, and its coconut filling nearly doubles the saturates. Per wrapper, the Twix is the smaller commitment.
Is one Twix finger an acceptable snack?
At 123 kcal it is a perfectly ordinary snack, comparable to a small buttered slice of toast, and it is one of the easiest portions in the chocolate aisle to actually stop at. The pitfall is treating each finger as too small to log; two of them are 246 kcal.
How many calories in a Twix per 100 g?
493 kcal per 100 g, from the manufacturer's label. That is below plain milk chocolate at 519 and almost identical to CoFID's generic caramel-biscuit bar at 501, so own-brand versions of the same idea log at roughly the same rate.
Does the caramel or the biscuit carry more of the calories?
The chocolate and caramel together carry most of the sugar, while the shortbread base is the least sugary component; a Twix runs 48 g of sugars per 100 g against 56 g for plain milk chocolate. The fat, 24 g per 100 g, is spread across all three layers.
