Small Retail Shop Profitability Case

Business context

A small local shop selling everyday products such as snacks, drinks, and household items. The owner wants to understand how much the business actually keeps each month.

The numbers below are simplified fictional examples used for educational purposes.

The numbers

Monthly sales revenue$18,000
Cost of goods sold (COGS)$11,700
Operating expenses (rent, utilities, staff)$4,500

Step-by-step calculation

Gross profit = Revenue − COGS = $18,000 − $11,700 = $6,300

Net profit = Gross profit − Operating expenses = $6,300 − $4,500 = $1,800

Gross margin = $6,300 / $18,000 = 35%

Net margin = $1,800 / $18,000 = 10%

Gross profit$6,300
Net profit$1,800
Gross margin35%
Net margin10%

What this means

For every $100 of sales, about $35 stays after paying for the goods, and only $10 stays after also paying rent, utilities, and staff. A 10% net margin is a reasonable starting point for a small retail shop, but it leaves limited room for unexpected costs, price discounts, or slow months.
