How many calories in a slice of white toast and butter?

Bread and butter is a staple breakfast food for many people. Knowing how many calories are in a slice of white bread with butter can help you make informed food choices to meet your health and nutrition goals.

Quick Answer

On average, one slice of white bread with 1 teaspoon of butter contains about 100-150 calories. However, the exact calorie count depends on the specific type and brand of bread, thickness of the slice, and amount of butter spread.

Calories in White Bread

The number of calories in white bread can vary greatly depending on the specific type:

  • One slice of basic thin-sliced white bread has about 70-80 calories
  • A thicker cut slice of artisan white bread may have 80-100 calories
  • White sandwich bread typically provides 75-90 calories per slice
  • Hearty artisan rolls and ciabatta breads may contain 100-150 calories per slice

In general, more dense and crusty artisan-style breads contain more calories per slice compared to softer, thinner sliced commercial white breads. The ingredients, brand, and exact thickness of the slice impacts the calories too.

Factors Affecting White Bread Calories

Several factors influence the calorie content in white bread:

  • Ingredients: Whole grain and whole wheat breads tend to be higher in calories than white breads made with refined, bleached wheat flour.
  • Slice size: The thicker the slice of bread, the more calories it contains.
  • Density: Chewy artisan breads typically pack in more calories per slice than lighter soft breads.
  • Crust: Breads with thicker crusts tend to be higher in calories than crustless slices.
  • Baking process: Artisan breads may be baked longer resulting in more calories than commercial white breads.

Calories in Butter

Butter contains about 100 calories per tablespoon (14 grams). The amount of butter spread on bread can vary greatly and impacts the total calorie count:

  • 1/2 teaspoon of butter: 25 calories
  • 1 teaspoon of butter: 50 calories
  • 1 tablespoon of butter: 100 calories

When eating bread and butter, most people spread around 1 teaspoon or a pat of butter containing 50 calories. But the actual amount can range from as little as 25 calories up to 100 calories if you’re more generous with the spread.

Factors Affecting Butter Calories

The main factors that determine the calories in butter include:

  • Portion size: Consuming larger amounts of butter means more calories.
  • Fat content: Full-fat butter has more calories than reduced-fat or light butter.
  • Brands: Some brands may have slightly more or less fat and calories than others.
  • Cooking method: Butter that’s clarified or ghee has fewer water-soluble components and more fat, resulting in more calories per tablespoon.

Total Calories in White Bread and Butter

Combining the typical calories in one slice of white bread with one teaspoon of butter, the total calories add up to:

  • White bread calories: 75-100
  • 1 teaspoon butter calories: 50
  • Total calories: About 125-150 calories

This estimate provides a ballpark calculation for a single slice of bread with butter. The table below shows a range of possible calorie totals:

Bread (1 slice) Butter (1 tsp) Total Calories
70 25 95
80 50 130
100 50 150

As you can see, the total calories can range from about 100-150 calories depending on the exact type of bread and amount of butter.

Serving Sizes

Typical serving sizes for bread and butter include:

  • Bread: 1 regular slice is generally around 1 oz (28g)
  • Butter: 1 pat or tsp = 1/2 tablespoon (8g)

The nutrition information on packaged bread labels is usually based on a standard slice of bread weighing around 28-30g.

Tips for Cutting Calories

If you’re trying to reduce your calorie intake, here are some tips for enjoying bread and butter with fewer calories:

  • Choose thin-sliced white bread over thick artisan bread slices.
  • Use reduced-calorie butter spreads or limit your spread to 1/2 teaspoon.
  • Skip the butter and add different toppings like smashed avocado, hummus, or jam instead.
  • Switch to whole grain bread varieties, which are more nutritious and filling.
  • Pick a lighter breakfast option like oatmeal or Greek yogurt on some days.

Nutrition Facts for White Bread and Butter

Here is the nutrition information for a typical serving of white sandwich bread and butter based on standard product labels:

White sandwich bread – 1 slice (28g)

  • Calories: 80
  • Carbs: 15g

One slice of white bread provides carbohydrates while the butter adds mostly fat and calories. There are small amounts of protein and fiber in a slice of enriched white bread as well.


White bread is not a significant source of vitamins and minerals. However, it does contain some B vitamins like thiamin, riboflavin, niacin, and folic acid from the fortification process. Butter provides small amounts of vitamins A, D, E, and K.

Healthier Bread Options

Although white bread and butter is fine in moderation, there are healthier bread options if you’re looking to add more nutrition:

  • Whole wheat bread: More fiber, protein, vitamins and minerals vs. white bread.
  • Sprouted grain bread: Made from whole grains that have started to sprout, providing more nutrients.
  • Rye or pumpernickel: Dense, fiber-rich breads that can aid digestion.
  • Sourdough: Uses bacterial fermentation to break down gluten and starch.

Factors That Increase Calorie Needs

While the average slice of bread and butter contains 125-150 calories, you may need more or less depending on your individual circumstances:

  • Children and teens need more calories for growth and development.
  • Active individuals and athletes require more calories to fuel exercise.
  • Pregnant and breastfeeding women need extra calories to support a baby.
  • Older adults may require fewer daily calories due to lower activity levels.

Talk to your healthcare provider or dietitian to determine your optimal calorie needs for your age, health status, and activity level.

The Bottom Line

One slice of white bread with 1 teaspoon of butter provides 100-150 calories, depending on the specifics. While not incredibly high in nutrients, bread and butter can be part of a well-rounded diet in moderation. Limit portions and opt for healthier bread choices to help keep your daily calorie intake on track.
