ProfitMetricLabHow it works
Round up: fixed costs ÷ (price − variable cost)
$3,000 ÷ ($50 − $20) = 100 units.
What the result means
Keep the time period consistent. Fixed costs belong to that period; unit price and variable cost belong to one sale. If contribution per unit is not positive, selling more cannot cover fixed costs.

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.
