How To Calculate Your 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 and net profit margin are critical numbers for every company

  • Gross Profit Margin is the measurement of a company’s efficiency during its “income production” process. It’s the amount (%) that’s left after paying the direct and indirect costs required to produce the goods or create the services you sell.
  • Net Profit Margin is the measurement of profit % you make for every $1 you earn in revenue. In other words, it illustrates how much money (as a %) that you retain (per $1 of revenue) after you pay all of your costs of production, company overhead expense, interest, and taxes.

So, 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.

Calculating 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)

An Example of Gross Profit and Gross Profit Margin Calculations:

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%.

Calculating 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

An Example of Net Profit & Net Profit Margin Calculations:

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.

Are You Clearer on How To Calculate GROSS and NET Profit Margins?

I hope this helped.

Of course, the fastest and easiest way to quickly see both your Gross and Net Profit dollars and percentages is to design your QuickBooks accounting system to automatically display those numbers on your Profit & Loss reports – for your company totals, or job by job.

QuickBooks or Enterprise has the power and flexibility to show income for each job, accumulate costs for each job, calculate gross profit for each job, and display both gross and net profit dollars and percentages for your entire business.

When you use your accounting software to help you see, and use, these critical numbers, you continually improve your results. And, as you improve your results, you maximize your profits.

My goal is to help business owners (like you) learn how to use QuickBooks and Enterprise accounting software as “the tool of choice for the job at hand!”

If this information was helpful, it’s only one small example of how to use your numbers to boost your profits! Take a few minutes to check out this extensive (and affordable!) online QuickBooks subscription training series.

From the Intuit Find a ProAdvisor 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 check up 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.”
