Net profit

Definition

The difference between the selling price and the cost of the goods

Profit after deducting all other expenses

Equation

Gross profit = revenue - cost of goods

Net profit = gross profit - operating expenses

What does it include?

Product cost only

Rents, salaries, marketing, electricity...

Third: Simplified equations to calculate net profit

Equation 1: Basic equation

Net Profit = Total Sales - (Cost of Merchandise + Operating Expenses)

Total Sales: Total income from selling products.
Cost of goods: The amount you paid to purchase or manufacture products.
Operating expenses: Such as rent, salaries, electricity, advertising.

Equation 2: Using ratios

Net profit = gross profit - total other expenses

Gross profit = sales - cost of goods

Equation 3: To calculate net profit as a percentage

Net profit margin = (net profit ÷ sales) x 100

📌 Example: If your sales are 10,000 riyals, and your net profit is 1,200 riyals:

Net profit margin = (1,200 ÷ 10,000) x 100 = 12%

Fourth: Practical examples from reality

Example 1: Coffee shop

Monthly sales = 20,000 riyals
The cost of materials (coffee, milk, sugar...) = 6,000 riyals
Rent = 3,000 riyals
Salaries = 5,000 riyals
Marketing = 2,000 riyals
Electricity and other expenses = 1,000 riyals

Gross profit = 20,000 - 6,000 = 14,000
Net profit = 14,000 - (3,000 + 5,000 + 2,000 + 1,000) = 3,000 riyals

Example 2: A cosmetics store

Sales = 50,000 riyals
Cost of goods = 20,000 riyals
Other expenses = 22,000 riyals

Net profit = 50,000 - (20,000 + 22,000) = 8,000 riyals
Profit margin = (8,000 ÷ 50,000) x 100 = 16%
