Donut Calculator

How many calories are in a donut?

Calories depend on the dough, size, glaze and filling. Yeast-raised donuts are light and airy; cake donuts are denser; fillings and toppings add the most.

Glazed and cake values are from USDA FoodData Central; filled and hole values are approximate averages and vary by bakery. Large bakery donuts can weigh 90–120 g, which pushes a single donut toward 400 calories or more. Chain restaurants publish their own nutrition guides, so check the brand's current guide for an exact figure – menus and recipes change.

Donut calorie burn calculator: how long to work it off

Exercise is measured in METs (metabolic equivalents) – how many times more energy an activity uses than sitting still. Calories burned per minute = MET × 3.5 × your weight in kg ÷ 200. The table uses values from the Compendium of Physical Activities for one 253-calorie glazed donut.

Heavier people burn more per minute, so they need less time. These are estimates of total calories used during the activity; the true figure varies with fitness, terrain and effort. A donut does not need to be 'earned' – the numbers simply help you fit treats into your overall day.

Donut nutrition: sugar, fat and carbs

A donut is mostly refined carbohydrate and fat, with little protein or fibre. One glazed donut provides about 14 g of sugar; the WHO suggests keeping free sugars below 10% of daily energy (about 50 g on 2,000 calories), with extra benefit below 5%. Because they are fried, donuts also add saturated fat – so they fit best as an occasional treat alongside meals with protein and fibre.

Donut recipe calculator: dough and batch size

For home bakers, a typical ring donut uses about 50–60 g of dough before frying. A dozen 55 g donuts needs roughly 660 g of dough; add about 5% for scraps you re-roll, so plan for around 690–700 g. Many basic yeast recipes built on 500 g of flour make 12–16 donuts, depending on thickness and cutter size.

• Proof shaped donuts until puffy and an indent springs back slowly – usually 30–60 minutes at warm room temperature.
• Fry at about 175–180 °C (350–360 °F). Oil that is too cool makes greasy donuts; too hot browns the outside before the centre cooks.
• Fry 1–2 minutes per side and drain on a rack.

Donut cost calculator: price per donut

Enter what you paid for flour, sugar, yeast, eggs, butter, milk, oil and glaze ingredients, and the share of each pack you used. The calculator divides the total by the number of donuts. For example, if a 12-donut batch uses $6.00 of ingredients, each donut costs $0.50. If you sell them, add packaging, energy and your time, then a margin; a simple rule is price = (ingredient cost + packaging) ÷ (1 − target margin).

Frying oil is the easiest cost to forget: a home batch can use 1–2 litres, though only part of it is absorbed and well-strained oil can often be reused a few times. Count only the share you use up.

Fitting a donut into a balanced diet

• Pair it with protein – eggs, yoghurt or milk – so the sugar is absorbed alongside a more filling meal.
• Choose a plain glazed or cake donut over filled and frosted versions to save 50–150 calories.
• Share a large bakery donut, or pick donut holes for a smaller portion.
• Watch the drink: a sweetened coffee drink can add as many calories as the donut itself.

Baked vs fried donuts

Baked donuts made in a donut pan usually contain less fat than fried ones because they do not absorb frying oil, but the difference depends on the recipe – some baked donut batters contain plenty of butter and sugar. Use the custom option and enter your recipe's nutrition per donut for an exact figure.
