Understanding how to calculate profit is crucial for business success. For retail businesses, accurate profit calculations can mean the difference between thriving and just surviving.
Retail businesses in Nigeria face unique challenges in managing profitability, from fluctuating market demands to supply chain complexities.
This guide will walk you through the essential steps for calculating different types of profit margins, helping you gain a clearer picture of your business’s financial health.
Understanding Profit in Retail
Profit, in the context of retail, is the financial gain after all expenses are deducted from revenue. We’ll explore the calculations of three main types of profit which are gross profit, operating profit, and net profit.

Calculating Gross Profit
Gross profit is the revenue minus the cost of goods sold (COGS) and the formula to calculate it is:
“Gross Profit = Revenue – COGS”
What this means using an example is that, if a retail store has a revenue of $50,000 and the COGS is $30,000, the gross profit will be $20,000. Gross profit indicates how much money is left to cover operating expenses and generate profit.
Calculating Operating Profit
Operating profit is your gross profit minus the operating expenses for your business And the formula for this is:
“Operating Profit = Gross Profit – Operating Expenses”
An example of this calculation in action is that, If the operating expenses for your business is $10,000, with a gross profit of $20,000, the operating profit will be $10,000. Operating profit reflects the profit from business operations, excluding non-operating expenses.
Calculating Net Profit
Net profit is the total revenue minus all expenses, including COGS, operating expenses, taxes, and interest. The formula for calculating Net Profit is:
“Net Profit = Total Revenue – Total Expenses”
So, If your total revenue is $50,000, and total expenses (including COGS, operating expenses, taxes, and interest) are $40,000, the net profit will be $10,000. Net profit shows the overall profitability and is crucial for evaluating the business’s financial health.
Profit Margin Calculations
Gross Profit Margin
“Gross Profit Margin = (Gross Profit / Revenue) X 100”
Example:
With a gross profit of $20,000 and revenue of $50,000, the gross profit margin is 40%.
Operating Profit Margin
“Operating Profit Margin = (Operating Profit / Revenue) X 100”
Example:
With an operating profit of $10,000 and revenue of $50,000, the operating profit margin is 20%.
Net Profit Margin
“Net Profit Margin = (Net Profit / Revenue) X 100”
Example:
With a net profit of $10,000 and revenue of $50,000, the net profit margin is 20%.
