Costing calculator

Garment Costing Calculator (FOB)

Build a garment FOB price from fabric consumption and price, trims, CM per dozen and other processes, then add commercial cost and profit, with the share of each cost element.

Method note: Cost sheet structures vary by company and buyer. Adapt the lines to your own costing format.

Inputs

In the same unit the fabric price is quoted in: kg for knits, meters or yards for wovens.

Trims and accessories (per piece)
Other processes (per piece)
%

Banking, documentation, inland transport to port and similar costs as a percentage.

Working
  1. Fabric = 2.4 × 5 / 12 = 1
  2. Manufacturing cost = 1 + 0.15 + 0.8 + 0.14 = 2.09
  3. + 5% commercial = 2.194
  4. + 10% profit = 2.414 USD

Formula

Formula
FOB=(F+T+CM+O)×(1+c100)×(1+p100)\text{FOB} = (F + T + \text{CM} + O) \times \left(1 + \dfrac{c}{100}\right) \times \left(1 + \dfrac{p}{100}\right)

FOB = (fabric + trims + CM + other) × (1 + commercial %) × (1 + profit %)

How the calculator works#

  • Fabric per piece = consumption per dozen × fabric price / 12
  • Manufacturing cost = fabric + trims + CM per piece + other processes
  • Commercial cost = manufacturing cost × commercial %
  • Profit = (manufacturing + commercial) × profit %
  • FOB = manufacturing + commercial + profit

A table shows each element's share of the FOB, so you can see what drives the price.

Worked example#

Defaults: 2.4 kg/dz fabric at 5.00 per kg, trims 0.15 per piece, CM 9.60 per dozen, print and testing 0.14 per piece, commercial 5%, profit 10%.

  • Fabric = 2.4 × 5 / 12 = 1.00 per piece
  • Manufacturing = 1.00 + 0.15 + 0.80 + 0.14 = 2.09
  • With 5% commercial = 2.194
  • With 10% profit = 2.414 per piece (28.97 per dozen)

Fabric is 41.4% of the FOB and CM 33.1%.

Interpreting the result#

Check the fabric share against similar styles; a large difference often means a consumption or price error. For quotation files, use the garment costing sheet, and see FOB cost for what the price should include.

Assumptions

  • Commercial cost is applied on manufacturing cost, and profit on the subtotal. Some companies apply both on manufacturing cost.
  • Freight beyond the FOB point, duty and buyer commissions are not included.

Common errors

  • Mixing per dozen and per piece values in the same sheet.
  • Forgetting shrinkage and shade allowances in fabric consumption.
  • Leaving out testing, inspection and sample costs that the buyer does not pay separately.

Questions

Are commercial cost and profit compounded?

Yes. Commercial cost is added to manufacturing cost, and profit is applied to manufacturing plus commercial cost. Some companies apply them separately; state the method you use on your cost sheet.

Which unit should fabric consumption use?

The same unit the fabric price uses: kg per dozen for knits, meters or yards per dozen for wovens.
