## Net profit margin – Meaning & Formula

Net profit margin is calculated by dividing the amount of net profit by net sale. This is one of the important profitability ratios used to gauge the overall profitability of a firm. This ratio is often used to measure the efficiency of a management to derive profit out of its sale.

Net profit is the amount which is left after deducting all direct and indirect expenses from the amount of total sales.

Net profit = Operating profit – Interest and taxes

In case a company pays dividend to its shareholders then dividend paid to preference shareholders (not to equity shareholders) is also deducted to get the net profit.

### Formula for the calculation of net profit margin:

Net profit ratio = Net profit/ Net revenue

The higher degree of this ratio shows that management is effectively generating profit while incurring lower costs.

## Operating profit margin – Meaning & Formula

Operating profit margin is one of the profitability ratios used to gauge the operating profitability of a firm. This ratio represents the relationship between operating profit and net sale of a firm.

Operating profit is calculated by subtracting the amount of cost of goods sold (COGS) and operating expenses from total sales. This is the profit which includes interest and taxes amount. That’s why, it is also known as ‘Earning before interest and taxes (EBIT)’.

Operating profit margin is also known as ‘Operating margin’.

### Formula for calculation of operating profit margin:

Operating margin is calculated by dividing the amount of operating profit by net revenue (net sale).

Operating profit ratio = Operating profit/ Net sale

As operating profit is calculated by deducting the amount of operating expenses from the amount of gross profit, below formula can also be used in calculation of operating margin

Operating profit ratio = (Gross profit – Operating expenses)/ Net sales

The higher degree of this ratio shows that management is effectively generating profit while incurring lower operating costs.

## Gross profit margin – Meaning & Formula

Gross profit margin is also known as ‘Gross margin’.

### Formula for calculation of gross profit margin:

Gross margin is calculated by dividing the amount of gross profit by net revenue (net sale).

Gross profit ratio = Gross profit/ Net sale

Gross profit is calculated by deducting the amount of cost of goods sold from net sales. Therefore, below formula can also be used in calculation of gross profit ratio

Gross profit ratio = (Sales – COGS)/ Net sales

Cost of goods sold (COGS) = Opening stock + Purchases – Closing stock

The higher degree of this ratio shows that management is effectively generating profit while incurring lower cost of goods sold.

## Days sales outstanding – Meaning & Calcualtion

Days sales outstanding (DSO) is the calculation of average number of days which a company takes in collection of its account receivables. This is an important element of order to cash cycle and it increases the cash flow of company.

DSO is used to check how many days it takes to collect the amount of credit sales during a period. Usually, this figure is calculated for month, quarter or year, however there is no such obligation in this regard.

### How days sales outstanding (DSO) is calculated?

DSO is calculated by multiplying the account receivable to the number of days for which DSO is being calculated and dividing the figure by total credit sales made during that period.

#### Formula:

(Accounts receivable × Number of days) / Total credit sales

Lower value of DSO indicates that the company is more efficient in collecting the amount incurred by credit sales.
