Gross Profit Ratio: Definition

The gross profit ratio (or gross profit margin) shows the gross profit as a percentage of net sales. The ratio provides an indication of the company’s pricing policy.

Certain businesses aim at a faster turnover through lower prices. Such businesses would have a lower gross profit percentage but a larger volume of sales.

Some businesses that have higher fixed costs (or indirect costs) need to have a greater gross profit margin to cover these costs.

Such businesses aim to cover their fixed costs and have a reasonable return on equity by achieving a larger gross profit margin from a smaller sales base.

Gross profit is defined as the difference between the net sales and the cost of goods sold (i.e., the direct cost of sales). The value of net sales is calculated as the sales minus returns inwards.

The gross profit ratio is a measure of the efficiency of production/purchasing as well as pricing. The higher the gross profit, the greater the efficiency of management in relation to production/purchasing and pricing.

Net Profit to Gross Profit Ratio

The net profit to gross profit ratio (NP to GP ratio) is an extension of the net profit ratio. If we deduct indirect expenses from the amount of gross profit, we arrive at net profit. In other words, gross profit is the sum of indirect expenses and net profit.

By expressing net profit (or indirect expenses) as a percentage of gross profit, we find out as to what portion of gross profit is consumed by indirect expenses and what portion is left as net profit.

These two items (net profit and indirect expenses) are the main considerations that drive a company’s pricing policy. If net profit as a percentage of gross profit is small, it may indicate any of the following three things:

  • Prices are driving the customers away
  • Expenses are too high in relation to the volume of business handled
  • Gross profit margin is inadequate

Gross Profit Ratio Formula

The gross profit ratio is calculated as follows:
Gross Profit Ratio Formula
In the above formula, the variables are defined:

Both components of the formula (i.e., gross profit and net sales) are usually available from the trading and profit and loss account or income statement of the company.

Example

Calculate and interpret the gross profit ratio from the following information of John Trading Concern for the year 2016.

  • Sales: $4,850,000
  • Sales returns: $50,000
  • Opening stock: $570,000
  • Purchases: $3,660,000
  • Closing stock: $630,000

Solution

1. Calculation of GP Ratio

The two figures that are needed to calculate the gross profit ratio are the net sales and the gross profit.

Since the data do not contain these figures, we need to calculate them at the outset. This can be done as follows:

Net sales = Gross sales – sales returns
= $4,850,000 – $50,000
= $4,800,000

In addition, the following calculation is applied for gross profit:

Gross profit = Sales – Cost of sales
= $4,800,000 – $3,600,000*
= $1,200,000
*Cost of sales = Opening stock + Purchases – Closing stock
= $570,000 + $3,660,000 – $630,000
= $3,600,000

At this point, we have calculated both net sales and gross profit. Therefore, we can easily compute the gross profit ratio as follows:

GP ratio = (1,200,000/4,800,000) × 100
= 25%

2. Interpretation of GP Ratio

John Trading Concern achieved a gross profit ratio of 25% during the period.

While this ratio may seem reasonable for a trading concern, it is impossible to pass a judgment on the adequacy (or otherwise) of this percentage unless the gross profit ratios of other businesses in the same field are known.

Other pieces of information that are important for supporting an interpretation are the company’s gross profit ratios over previous years, or the target gross profit ratio set by the company’s budget for the year.

This is a very important aspect of using ratios as a tool of evaluation. A ratio in itself is not particularly useful unless it is compared with similar ratios obtained from a related source.
