A 2D companion to the 3D profitability lab: the same cost-plus, value-based and competitive pricing math driving a live bar chart and a monthly-profit-versus-volume curve, so you can read the numbers directly instead of orbiting a scene.
Cost per jar is built from a variable component (honey, jar, lid, label) plus fixed overhead spread across the month's batch; profit per jar is what's left once both are covered, and break-even is the batch size at which fixed costs are finally cleared.
Set your price, variable cost, monthly overhead and batch size, then compare against a cost-plus, value-based or competitive pricing target. Watch the bar chart and the profit-vs-volume curve update live, with the break-even point marked on the curve.
A batch can look profitable jar-by-jar and still lose money overall if it never reaches its break-even volume — the point where cumulative margin finally covers that month's fixed overhead.
