ProfitMetricLabHow it works
(Revenue − costs) ÷ revenue × 100
$10,000 revenue and $6,500 costs produce a 35% margin.
What the result means
A higher margin leaves more room for unexpected costs. Include all costs for a net margin, or only cost of goods for a gross margin. Do not compare the two as if they were identical.

Common questions
Are my inputs saved?
We do not store or submit form inputs. Reloading restores the example values.
Is the result exact?
The display rounds to at most two decimal places; intermediate values retain their precision. Assumptions may differ from your actual situation.
