A business can have a healthy gross profit and still be losing money overall — which is exactly the kind of thing that catches new owners off guard when they only look at one of these two numbers.
Gross profit: revenue minus the direct cost of making it
Gross profit is what's left after subtracting the direct cost of goods or services sold — materials, direct labor, whatever it actually costs to produce what you sold. It tells you how efficiently your core product or service makes money, before anything else is factored in.
Net profit: what's actually left after everything
Net profit takes gross profit and subtracts every other operating cost — rent, salaries, marketing, software subscriptions, loan interest, taxes. This is the number that answers "did the business actually make money this month," and it's usually significantly smaller than gross profit.
A worked example
| Item | Amount |
|---|---|
| Revenue | $10,000 |
| Cost of goods sold | $4,000 |
| Gross profit | $6,000 |
| Rent, salaries, marketing, other overhead | $5,200 |
| Net profit | $800 |
A $6,000 gross profit looks strong on its own, but once overhead is accounted for, the business only actually kept $800. Looking at gross profit alone would have painted a much rosier picture than reality.
Why both numbers matter, for different reasons
A shrinking gross profit usually points to a pricing or production cost problem — you're either charging too little or spending too much to make what you sell. A shrinking net profit despite healthy gross profit points to overhead running too high relative to what the business brings in.
