Manufacturing fixed costs include factory rent or mortgage, equipment depreciation, management salaries, insurance, and regulatory compliance expenses. These costs remain constant regardless of production volume and can be substantial for capital-intensive operations.

As production volume increases, fixed costs are spread across more units, reducing the cost per unit. Additionally, bulk material purchasing often lowers variable costs. Both effects work together to improve margins as you produce beyond the break-even point.

Yes, each product has different variable costs and selling prices. Calculating break-even per product helps you identify which items are most profitable and allocate production capacity accordingly. Shared fixed costs can be allocated proportionally by production volume.
