How To Calculate Gross Profit Margin and Net Profit Margin

Every business owner needs to know how to calculate their gross profit margin (%) and net profit margin (%).
After all, it’s what shows you how much profit you’re making!

As a business owner or bookkeeper, the most important numbers you’ll ever need to know may very well be your profit margins.

There are two kinds of profit margins, gross profit margin, and net profit margin.

Gross Profit Margin

Gross profit margin and net profit margin are critical numbers for every company

Gross Profit Margin, a critical financial metric, is the percentage of a company’s revenue they get to keep as “gross profit” after subtracting the direct costs required to produce the goods or services they sell, (also known as the Cost of Goods Sold (COGS).)

It is a measure of operational efficiency because the higher a company’s gross profit margin, the more they earn on each dollar of sales. Those earnings can be utilized to pay other costs or satisfy debt obligations. The Gross Profit Margin is often synonymous with Gross Margin Ratio.

Net Profit Margin

Net Profit Margin is the percentage of net income or profit generated from a company’s total revenue. It is a critical financial metric that indicates how efficiently a company converts its sales into profits. It illustrates how much money (as a %) you retain as profit after you pay all of your costs of production, company overhead expense, interest, and taxes. A higher net profit margin reflects better profitability, while a lower margin may suggest challenges in cost management or pricing strategies.

How Do You Calculate Profit Margin?

It depends on whether you’re trying to calculate gross profit margin or net profit margin. Both tell you important (but different) information about the overall financial health of your business. So let’s look at them one at a time.

How To Calculate Gross Profit Margin

  • Gross Profit ($) = Total Revenue – Cost of Goods or Services Sold
  • Gross Profit Margin (%) = Gross Profit / Total Revenue x 100 (yields a percentage)

Gross Profit and Gross Profit Margin Calculation: An Example

You own a contracting business and in one week…

  • Your total revenue = $10,000
  • Cost of Services Sold: Two employees paid $1,600 gross payroll + another $1,000 for burden costs + $3,400 for construction materials = $6,000 ‘production cost.’

To compute gross profit for this example:

$10,000 gross revenue – $6,000 production cost = $4,000. So, your gross profit amount for the week is $4,000.

To calculate your gross profit margin percentage:

$4,000 / $10,000 x 100 = 40%. So, your gross profit margin for the week is 40%.

How to Calculate Net Profit Margin

  • Net Profit ($) = Gross Profit (as computed above) less Company Overhead, Interest, and Taxes (also known as Net Income or “the bottom line” in financial statements).
  • Net Profit Margin (%) = Gross Profit less Company Overhead, Interest, and Taxes / Total Revenue x 100

Net Profit and Net Profit Margin CalculationAn Example

Let’s say you own the same contracting business as the first example, but instead of just subtracting the cost of goods and services sold, this time you also include all of your company overhead expenses, interest, and taxes. We determine that the additional cost is $3,000.

To compute net profit for this example:

$10,000 Revenue – $6,000 production costs – $3,000 company overhead, interest, and taxes = $1,000. So your Net Profit amount for the week is $1,000.

To calculate your net profit margin percentage:

$1,000 Net Profit / $10,000 Revenue x 100 = 10%. So your Net Profit margin for the week is 10%.

Or you can look at it this way, for every $100 you earn, you will keep a net profit of 10% or $10.

Customer Praise For Diane Gilson, Info Plus Accounting, and BuildYourNumbers.com

⭐⭐⭐⭐⭐ From the Intuit FindAProAdvisor website:
“Diane is the expert of experts. I wouldn’t go anywhere else and feel that I found a pot of gold at the end of a rainbow. I am well taken care and so much of my business and financial reporting has been simplified by my work with Diane. There’s been a number of times where we would find double entries that I would have never noticed had I not set up things the way she suggested. Diane did a 35 point checkup on my books and developed a long-range plan that resulted in a set of books that I can cost account, pay commissions and accurately understand my bottom line. We once audited my Worker’s Comp policy and we discovered they charged me for a period that this particular company hadn’t even covered me for. I was able to get $4,500 back. That was actually money earned back! We don’t make those mistakes anymore because we have way better, tighter controls. And we are much more protected from fraud and embezzlement. I save money when I work with Diane. I think the most critical thing she provides to small businesses is the controller and expert level when you can’t necessarily afford to hire an in-house controller.”
