What is net profit margin?

Net profit margin is a specific portion of your profits that you keep after taking off all kinds of expenses, including rent, utilities, taxes, and other such expenses. Sometimes also known as net income margin, it is basically a financial ratio that gauges the business’s profitability. It is like disclosing the amount you settle with after subtracting all your business expenditures. And that’s what we refer to as net profit margin.

The higher the profit margin, the better the business profitability. But if it plunges, the company is making a loss. Due to its ability to show the actual profit retained, it emerges as a top pick among other ways to assess profitability.

Net profit margin example

Let us assume a physical retail store generates $80,000 in monthly revenue by selling groceries. But, like other such businesses, they also incur unavoidable expenses like store rent, local taxes, water or electricity bills, amounting to the total of $19,000. Separating them, $61,000 (after subtracting $19,000 from $80,000) is what comes out as the net profit.

Using the formula for net profit margin, that’s 76.25% of net profit margin, which your retail store retains from its total revenue. A higher margin signifies greater profitability as well as better control over finances.

How to calculate net profit margin?

Net profit margin calculation is not a complex process. First, you need to find out two key factors:

Net Profit: It refers to the leftover amount after removing all business expenses, taxes, interest, salaries, rent, and operational costs.
Total Revenue: It refers to the total income produced through sales before deducting expenses.

Both figures are essential to explore the profit you are accumulating after separating all expenses. Once both figures are available, the calculation becomes pretty much easier.

Assuming you have discovered both – net profit as well as total revenue, let us jump into how to calculate using the right formula.

Net profit margin formula

The following formula helps calculate the percentage of revenue a business keeps as profit after deducting all expenses. The result is expressed as a percentage, which makes it easier to evaluate profitability and compare financial performance over different periods, of course.

Net profit margin = (Net profit / Total revenue) X 100

Say, your business generates, for example, the total revenue of $120,000 in a quarter. But, when we deduct all business expenses, the company settles with a net profit of $24,000.

Net Profit = $24,000
Total Revenue = $120,000

Calculation: (24000/120000) X 100=20%

As a result, the business retains 20% of its revenue as net profit. That means for every $1 earned in revenue, the company keeps $0.20 as actual profit after covering all expenses.

Why is net profit margin so important?

Below are a few reasons why calculating profit margin matters for any size of business.

1. Evaluating profitability

Calculating profit margin matters because it discloses how much profit you are generating in a defined period. You can evaluate how much of the amount can be kept aside from the total revenue. The same approach is also important in comparing performance with other businesses or previous periods.

2. Identifying current trends

Profit margin, when determined accurately, can also reveal ongoing financial trends. Which means you can see whether profits are growing, declining, or stable. These trends allow you to spot changing patterns and, accordingly, make adjustments to budget plans or operational strategies to mitigate any financial issues.

3. Financial projections

Net profit margin also comes in handy when predicting finances for the future. Because it utilizes both past and current profit margins to project your future earnings. That way, you can make robust budget plans and seize the right investment opportunities, aiding you in accomplishing financial goals early.

4. Decision-making

Since profit margin indicates the overall profitability of your business, it is way easier to make data-backed decisions. This also includes deciding whether to cut off some hard-hitting expenses or revise pricing strategies. That means you no longer have to rely on guesswork whenever making important decisions.
