Gross Profit vs Net Profit: What's the Difference?

The one-line definitions

• Gross profit = Revenue − Cost of Goods Sold (COGS).
• Net profit = Revenue − COGS − Operating Expenses − Interest − Tax.

Gross profit answers: "Does each product sell for more than it costs to make?" Net profit answers: "Does the entire business make money after running it?"

A worked example

A small ecommerce business does $500,000 in revenue this year.

Same business, two stories. "50% gross margin" sounds excellent. "14.5% net margin" is healthy but not spectacular. Both are true.

Why investors care more about net profit

Net profit is what's actually available to pay shareholders, reinvest, or save. Gross profit is a number on a spreadsheet. A business can have stellar gross margin and still be unprofitable if overhead is too high — software companies are often this story in their early years. A business can have modest gross margin and be massively profitable through ruthless cost control (Walmart, Costco).

Why operators care more about gross profit

Gross profit is the lever you can move quickly. Raise prices, cut COGS, change product mix — gross margin moves within a quarter. Operating expenses (rent, salaries) are mostly locked in. Day-to-day operators focus on gross margin because that's the controllable variable.

Where each gets used

• Pricing decisions: gross margin. You want each sale to make sense before overhead.
• Tax filing: net profit. Tax is calculated on net, not gross.
• Loan applications: both — banks look at debt-service coverage which uses net profit + interest add-back (≈ EBITDA).
• Investor pitches: gross margin to show scalability; net margin (or path to it) to show viability.
• Selling the business: net profit and EBITDA — buyers value the bottom line they'll inherit.

The trap: rising revenue with falling net margin

Many small businesses grow revenue happily while net margin shrinks. Why? They add staff, software, and office space faster than gross profit grows. Revenue doubles, gross profit doubles, but operating expenses triple — net profit collapses. Always track gross profit per employee and OpEx as a percentage of revenue alongside top-line growth.

Bottom line

• Gross profit = how much each sale clears after direct cost.
• Net profit = what's left after running the entire business.
• Operators optimise gross; investors value net.
• The gap between the two is your overhead — watch it relative to revenue.
