A plain avocado toast — one slice of sourdough, half an avocado — is about 230 calories (~960 kJ). But "avocado toast" is a stack, not a recipe: pile on a second slice, a whole avocado, an egg, feta and an oil drizzle and you're at 600+. Build yours below to get the real number.

There's no single number — it's a stack
Avocado toast isn't a fixed dish, so it has no fixed calorie count. It's three layers you choose: the bread (a white sandwich slice is ~75 calories; a thick sourdough slice ~120), the avocado (half a Hass ~110, a whole one ~240), and whatever goes on top. A genuinely plain version lands near 230 calories; the same name on a café menu, built bigger, is routinely double that.
Where the calories come from
Most people assume it's the avocado — and the avocado is calorie-dense, because its calories are essentially oil. But on a loaded toast it's often the toppings that tip it over: a poached egg adds ~70, feta ~80, smoked salmon ~45, and an innocent-looking olive-oil drizzle ~40 per teaspoon. Stack three of those and you've quietly added a small meal. The bread choice matters too — see how bread types compare.

Frequently asked
How many calories are in avocado toast?
A plain avocado toast — one slice of sourdough with half an avocado — is about 230 calories (around 960 kJ). Add a poached egg and it's roughly 300; a loaded café version with two thick slices, a whole avocado, egg, feta and an oil drizzle can reach 550–650.
Is avocado toast healthy?
Plain, it's a balanced mix of fibre, monounsaturated fat and slow carbohydrate. What changes the picture is the build: a single slice with half an avocado is light, while two slices, a whole avocado, cheese and oil turn it into a 600-calorie meal.
How many calories in avocado toast with egg?
About 300 calories for one slice of sourdough, half an avocado and a poached egg. A fried egg adds a little more from the cooking fat.
Why is café avocado toast so much higher in calories?
Cafés use larger, thicker bread slices, often two of them, a generous amount of avocado, and finishing touches like feta, halloumi and an olive-oil drizzle — each adding 40 to 90 calories. Those extras, not the avocado, are what push it past 500.

The avocado is the cheap part of the calorie bill — it's the second slice and the drizzle that order the bigger plate.
