Gross Profit Margin (GPM)

The Gross Profit Margin (GPM) is a financial metric that quantifies a company's profitability by expressing gross profit as a percentage of net sales (revenue). Mathematically, it's calculated as:


GPM = Net SalesNet Sales − Cost of Goods Sold (COGS)​ × 100%

The GPM indicates the proportion of revenue remaining after accounting for the direct costs associated with producing or acquiring the goods sold (COGS). A higher GPM signifies greater efficiency in the core production process and a stronger ability to convert sales into profit before operating expenses (like administration, R&D, and marketing) are considered. It's a key indicator of pricing strategy effectiveness and cost control over manufacturing/sourcing.



Use Case

TechWidgets Inc. manufactures smart home devices.


Metric

Value

Net Sales (Revenue)

$5,000,000

Cost of Goods Sold (COGS)

$3,500,000


Calculation:

  1. Calculate Gross Profit:
$5,000,000 (Net Sales) − $3,500,000 (COGS) = $1,500,000
  1. Calculate GPM:
GPM = $5,000,000$ / 1,500,000 ​× 100 = 30%


The 30% GPM means that for every dollar of revenue, TechWidgets Inc. retains $0.30 after paying for the materials, direct labor, and manufacturing overhead (COGS) required to produce the devices. This $0.30 is available to cover operating expenses and contribute to net income. Management can use this GPM:

  1. Benchmarking: Compare against industry peers or historical performance. A decline could signal rising raw material costs or inadequate pricing.
  2. Pricing Strategy: Justify price increases or evaluate the impact of bulk-order discounts.
  3. Operational Efficiency: Target cost reduction measures in sourcing or production to boost the margin.
