Net margin versus gross margin
Gross margin stops after direct costs. Net profit margin uses the final profit figure, so it reflects the full cost structure represented by your accounts.
Interpreting negative margin
A negative result means the business lost money for the entered period. Comparing consistent periods can show whether losses are narrowing or widening.
Worked example
$100,000 revenue and $15,000 net profit produce a 15% net profit margin. A $5,000 loss would produce -5%.
Frequently asked questions
Practical questions people ask about this tool
What if revenue is zero?
The percentage is not calculable because the formula divides net profit by revenue.
Is net profit margin the same as gross margin?
No. Net profit margin uses profit after all expenses represented in net profit, while gross margin uses revenue less COGS.
Can net profit margin be negative?
Yes. A negative percentage indicates a net loss for the period.
