How many calories in bread?
65–85 kcal
One slice of white bread is about 65–85 calories. Brown and multigrain are within a few calories — the difference is fibre, not energy.
By serving
Serving by serving.
Ranges rather than single numbers. Home cooking has no standard serving, and the same dish made in two kitchens genuinely differs by this much — a single figure would be false precision.
| Serving | Calories |
|---|---|
| 1 slice white (~28 g) | 65–85 |
| 1 slice brown or whole wheat | 70–90 |
| 1 slice with 1 tsp butter | 105–125 |
| Per 100 g | 250–280 |
Per one slice of white bread: 2 g protein · 13–15 g carbs · 0.8 g fat
Why the range
What moves this number.
If you want a better estimate than the table gives, these are the things worth paying attention to. Everything else is noise by comparison.
- Slice thickness. A sandwich loaf slice and a thick-cut slice differ by 30–40%.
- What goes on it. Butter, jam or peanut butter typically add more calories than the bread carries.
- Toasting. Changes nothing.
- Brown versus white. Effectively the same calories. Choose brown for fibre, not for the count.
Logging it
You do not need this table every day.
Looking a number up works once. Doing it for every item of every meal is the reason most people stop tracking within a fortnight.
BetterCal has no database to search. Say or type the meal the way you would describe it to a person — "bread and dal" — and it is logged with calories and macros in one go. If your version differs from the estimate, correct it once and it remembers, so over a few weeks the numbers converge on your kitchen rather than an average of everyone else's.
Frequently asked questions
Is brown bread lower in calories than white?
No — they are within about 5 calories a slice. Brown bread has more fibre, which helps with fullness, but it is not a lower-calorie food.
How many calories in 2 slices of bread with butter?
Roughly 210–250 with a teaspoon of butter on each slice.
Why is this a range and not one number?
Because the honest answer is a range. Serving sizes are not standardised and cooking fat varies enormously between kitchens. A single confident figure would be more convenient and less true. See how accurate calorie estimates really are.
Do I need to weigh food to track it properly?
No. Weighing improves precision that you mostly do not need — being consistently within 10% is enough to lose or gain weight predictably. The easiest way to track calories covers the method.
