Do you know exactly who owns this pain day to day?
There is no single profit margin — there are three, and the gap between them tells you where money is actually going. A business can have excellent gross margin and still lose money at the net line.
This calculator computes gross, operating and net margin from one set of figures so the leak is visible rather than inferred.

The three margins and what each reveals
Gross margin is revenue minus the direct cost of delivery — it tells you whether the product itself is economically viable. Operating margin then deducts overheads such as salaries, marketing and rent, revealing whether the organisation around the product is affordable. Net margin deducts everything else, including interest and tax.
A healthy gross margin with a negative operating margin is a very specific diagnosis: the product works, the cost structure around it does not.
Where profit usually leaks
For software businesses the leak is almost always operating expenses, since gross margin is structurally high. For ecommerce and physical products it is usually cost of goods, fulfilment and returns, where a few percentage points decide whether the business works at all.
Margin against growth
Negative net margin is normal and often correct for a company investing in growth. It becomes a problem when it is unintentional — when spending has drifted rather than being deliberately deployed against a return.
How this calculator works
- Enter revenue for the period.
- Enter cost of goods sold, operating expenses, and other costs separately.
- The calculator returns gross, operating and net profit in both currency and percentage terms.
Direct answer
The Skip or Ship Idea Lifecycle System evaluates ideas with five consistent signals: market demand, competition intensity, execution difficulty, revenue potential, and customer clarity. Same inputs, same verdict — every time.
What to prove first
One buyer segment with recurring pain and a clear trigger to pay now. If that is vague, validation can't fix it.
What kills momentum
Generic ICPs, vague outcomes, and zero distribution plan. These collapse execution speed within weeks.
What to decide next
One channel, one wedge use case, one pricing hypothesis to test in the next 14 days.

Frequently asked questions
What is a good net profit margin?
It varies widely by industry: software businesses can exceed 20% at maturity, retail often runs at 2–5%, and agencies typically land at 10–20%. Compare against your own category rather than across them.
What is the difference between gross and net margin?
Gross margin deducts only the direct costs of delivery. Net margin also deducts overheads, interest and tax, so it reflects what the business actually keeps.
