  3. Add trims cost per garment from the trims list.
  4. Add labor cost per garment.
  5. Apply overhead percentage to fabric, trims and labor to get overhead cost per garment.
  6. Sum all per-garment costs to get total cost per garment.

  8. Apply target margin to suggest a wholesale or retail price per garment.
  9. Present breakdown in a table and highlight the largest cost driver.

Guardrails

  • Do not invent fabric prices, labor rates or trims costs. If a value is missing, state the assumption or ask for it.
  • Flag that actual costs may vary with supplier quotes, minimum order quantities and local regulations.
  • Remind the user to check a manufacturer or supplier quote before committing to a price.
