Overhead absorption (labor-hour method)
Sum one year of facility and support costs not tied to a specific SKU: rent, utilities, equipment depreciation, maintenance, supervision/QA labor, insurance, and admin/back-office support. Pull this from your P&L or ask finance for the facility cost center total.
Total hours your direct labor staff actually clocked on production/service work in a year (headcount × hours/week × weeks worked, minus PTO/holidays, or pulled straight from timekeeping). This is the base the overhead gets spread across.
Consumables
Add up the cost of every component actually used up per unit of output — packaging, filters, tubing, single-use parts, etc. — then divide by the mL that batch produced to get a per-mL rate. Include a waste/scrap factor if loss is typical for this process.

Overhead is absorbed via the labor-hour method: annual overhead ÷ annual direct labor hours = an overhead rate per labor hour, applied alongside your loaded labor rate. Watch for double-counting — confirm with finance whether your labor rate or consumables cost already carries a G&A or facilities markup before layering overhead on top again.
