How Many Calories Are in Bread & Butter? (In Charts)

It’s one of the most basic yet popular foods we love to snack on, either on its own or as a side dish, but how many calories does this simple snack really contain.

It’s a question that is difficult to give a straightforward answer to because bread comes in so many shapes and sizes, with different ingredients and slice thicknesses.

So, I’ve researched average bread weights and sizes and specific brands to give you a definitive answer on exactly how many calories are in your slice of bread and butter. Read on to find the information you need in our quick and easy charts.

How Much Butter Do You Put on Bread?

Before you can work out how many calories are in your slice of bread and butter, you need to know how much butter you have on your bread.

Because butter is high in calories, a small amount can make a big difference, especially if you’re trying to stick to a certain amount of calories per day.

I did some research to find an average amount of butter or margarine per slice of bread, and I found the following;

The average amount of butter or margarine you need to lightly cover a slice of bread is 5g or one teaspoon per slice. 10g of butter gives a thicker coverage, and 15g gives a very thick butter covering per slice.

The image below shows how much butter coverage you get with 5, 10, and 15g of butter to help you work out how much you usually use.

Average Calories in Bread & Butter or Margarine

The tables below show the calories for average bread slice weights with butter or margarine, depending on the size and thickness of your slice.

To help you find the correct information, I’ve split them out into small 400g loaves and large 800g loaves, which are the two most popular bread sizes sold in shops and supermarkets.

Because people tend to spread their butter more thickly when eating bread and butter, I’ve based the charts on 10g of butter or margarine per slice.

If you need to know the calories for a specific brand and type of bread, you might want to skip to the next section.
