## Example: calculating gross profit margin

Below is an example profit margin for a bakery that sells sweet rolls, savoury rolls and a variety of bread loaves.

For each of their products, the cost of goods sold (cost to make), sales revenue (sale price), gross profit (sales revenue minus cost of goods sold) and gross profit margin are listed.

Product Cost to make Sale price Gross profit Gross profit margin
Sweet rolls \$0.50 \$2.00 \$1.50 75%
Bread loaves \$1.00 \$3.00 \$2.00 66%
Savoury rolls \$1.50 \$2.00 \$0.50 25%

If the bakery sold 180 loaves of bread, 106 sweet rolls and 100 savoury rolls a day, the gross profits would be:

Product Daily target Gross profit Gross profit margin Daily gross profits
Sweet rolls 106 \$1.50 75% \$159
Bread loaves 180 \$2.00 66% \$360
Savoury rolls 100 \$0.50 25% \$50

As a business owner this is a useful exercise to understand what your most profitable and unprofitable products lines are. You may even decide to stop offering some unprofitable lines and concentrate on your most profitable products.
