Reading a finished costing sheet from fabric to final FOB

Level: FoundationTime: 45 minutesOrder used: A (the T-shirt)Tool: Cost build-up sheet
This lesson is for anyone handed a finished costing sheet and asked to understand it: a merchandiser, a factory owner, a buyer, or a student. Lesson 1.1 is the prerequisite. Course 7, lesson 2 already taught how a sheet's shares of price are calculated by formula; this lesson teaches what to ask about each line's own dollar value. Money figures are teaching examples in US dollars.

This page teaches how to read each line of a finished costing sheet back to the numbers behind it, for anyone handed a sheet they did not build

A finished costing sheet shows five dollar figures and a total. Reading it well means more than accepting those figures; it means knowing what underlying numbers produced each one, so a wrong or outdated figure can be caught before it is quoted to a buyer or approved by an owner. Lesson 1.1 grouped the five components into three families by what drives them. This lesson goes one line at a time through Order A's own finished sheet and shows exactly which numbers feed fabric, trims, making, overhead and profit. This lesson mainly teaches the money flow: how to trace a printed figure back to the numbers that built it.

03Before you start

What you need, and what this lesson does not cover

You need: the three cost families from lesson 1.1 (material costs, conversion costs, profit) and the five cost components from Course 7.

By the end of this lesson you can:

  • state the two numbers that combine to produce a fabric cost figure;
  • explain why a trims figure is usually a lump sum rather than a calculation shown on the sheet;
  • explain what a making charge and an overhead figure each represent, even without seeing their own build-up;
  • read profit as a decision, not a calculated residual left over by accident;
  • ask the right question about any costing-sheet line before trusting it.

Not covered here: why the same garment can cost differently for two orders (lesson 1.3), common costing mistakes (lesson 1.4), and building a costing sheet from a blank page (lesson 1.5).

04Key terms

Words you will meet in this lesson

TermMeaning
Cost componentOne part of a garment's total price: fabric, trims, making, overhead, or profit.
Fabric costThe cost of the fabric used in one garment, driven by fabric price per kilogram and consumption per piece.
Making chargeThe labour cost of cutting, sewing and finishing one garment.
OverheadA factory's running costs that are not fabric, trims or direct labour: rent, electricity, management salaries and similar costs, shared across all the pieces it makes.
ProfitThe money left over after all costs are paid, out of a selling price.
FOB priceThe price the factory charges for the garment, delivered on board the ship at its own port.
Share of priceOne cost component's dollar value divided by the total price, usually shown as a percentage.
05Teaching
The rule

Every line on a finished costing sheet is either a calculation from two visible numbers, or a figure that must be asked about, and reading a sheet well means knowing which is which

Some costing-sheet lines are built from numbers a reader can check directly: fabric cost, for instance, comes from a fabric price per kilogram and a consumption figure per piece, both real, checkable numbers. Other lines, like trims, making and overhead, are usually shown as one lump dollar figure, with no build-up printed on the sheet itself, because their own underlying numbers, a bill of small items, an SMV and a labour rate, an allocation formula, live in separate documents. Profit is neither: it is a decision the factory made, not a calculation to trace at all. Reading a costing sheet well means treating these three kinds of line differently, not assuming every figure has the same kind of backup.

Fabric: 5.60 USD per kilogram x 0.205 kg per piece = 1.148, rounds to USD 1.15
What you meet in real life

How much build-up a costing sheet shows varies by company, by cost component, and by who will read it

What can differThe shapes you will meetWhy it matters to you
How much detail fabric showsSome sheets show fabric price and consumption as two separate columns, so the reader sees the calculation. Others show only the final fabric dollar figure, as Order A's own sheet does in Course 7.A sheet with visible price and consumption lets you check a fabric change yourself; a lump figure means you must ask the merchandiser for the two numbers behind it.
How trims are itemisedA simple style like Order A's T-shirt often shows trims as one lump figure, since the item list, labels, thread, care label, is short. A trim-heavy style may show trims broken into several rows, one per item, each with its own small cost.The more items a style has, the more useful an itemised trims section becomes for finding a single overpriced item.
Export or domestic framingOrder A's sheet ends in an FOB total, since Northline Apparel is an export buyer. Cedar & Co.'s own domestic sheet keeps the same five components but ends in an ex-factory total, with local delivery added separately rather than export freight.The reading method is identical either way; only the label on the final total line changes.
Who assembles the sheet, and for whomA merchandiser at Delta Garments builds the sheet from the factory's own cost data. A buyer's own team may rebuild the same five lines independently, using market price benchmarks, to check whether the factory's figures look reasonable.The same finished sheet can be a quotation from one side and a benchmark check from the other; reading it well matters to both.
The case we follow

Mona walks a new colleague through Order A's finished costing sheet, line by line

A new hire at Delta Garments is shown Order A's finished costing sheet for the first time. Mona explains what stands behind each of the five lines before the new colleague is allowed to quote from it unsupervised.

LineOrder A (USD per piece)What actually feeds this line
Fabric1.15Fabric price 5.60 per kilogram times consumption 0.205 kilogram per piece
Trims0.20A lump sum for labels, thread and care label bought from Trimco; no further split shown
Making1.10The garment's own SMV times Delta Garments' labour cost per minute; the SMV build-up is a separate document
Overhead0.49Delta Garments' total overhead cost, allocated across all the pieces it runs; the allocation rate is set factory-wide
Profit0.26What Delta Garments decided to keep on this order, not calculated from any other number
Total (FOB price)3.20The sum of the five lines above
The worked number

Fabric's own two numbers, price and consumption, are the only line on the sheet a reader can fully rebuild without another document

Fabric price per kilogram: 5.60 USD (quoted by Colorline Dyeing)
Fabric consumption per piece: 0.205 kg (marker weight, including 7% wastage)
Fabric cost: 5.60 x 0.205 = 1.148, rounds to USD 1.15
Fabric cost build-up, Order APrice 5.60 per kgConsumption 0.205 kg= USD 1.15
Fabric cost is the one line whose own two feeding numbers usually sit right on the sheet. Multiply price per kilogram by consumption per piece and the result matches the printed fabric figure.
The method

Read any finished costing sheet in five steps

  1. Read the total first, then each of the five component lines beneath it.
  2. Check fabric's own two numbers, price per kilogram and consumption per piece, since these usually sit on or beside the sheet.
  3. Ask, for trims, making and overhead, what document holds the build-up behind the lump figure shown.
  4. Treat profit as a decision, and ask why that margin was chosen, not what calculation produced it.
  5. Confirm the total is the sum of the five lines, using the formula check from Course 7, lesson 2.
The trap

A common mistake is assuming every line on a costing sheet has a visible calculation behind it, the way fabric does

Fabric's own build-up, price times consumption, is usually printed or easy to ask for, and a reader who has just checked it can wrongly assume every other line works the same way. Making, overhead and trims are typically shown as one dollar figure with no calculation on the sheet at all, their own supporting numbers living in a separate SMV sheet, an overhead allocation model, or a trims bill of materials. A reader who expects a visible calculation for making or overhead and finds none may wrongly conclude the figure is unsupported or arbitrary, when it is simply documented elsewhere.

Fabric (visible on the sheet)Making (backed up elsewhere)Price 5.60 x consumption 0.205= 1.15, both numbers visibleon or near the sheet itself.Shown as one lump figure, 1.10.SMV and labour rate live in aseparate work-study document.
A missing calculation on the sheet does not mean a figure is unsupported. Fabric's build-up is usually visible; making's build-up usually is not, though it still exists elsewhere.
06In plain words

A finished costing sheet shows five dollar numbers and a total. Reading it well means knowing where each number came from, not just trusting it because it is printed. Fabric usually shows its own two feeding numbers, a price and a consumption figure, right there or nearby, so anyone can check it. Trims, making and overhead are usually one lump number each, with their own detail kept in a separate document, not because they are less trustworthy, but because their detail belongs somewhere else. Profit is not calculated from anything at all; it is simply what the factory decided to keep. Knowing which kind of line you are looking at tells you what question to ask.

07Quick check
  • Fabric cost usually shows its own two feeding numbers: price per kilogram and consumption per piece.
  • Trims, making and overhead are usually shown as one lump figure, with detail kept in a separate document.
  • Profit is a decision the factory made, not a number calculated from any other line.
  • A missing on-sheet calculation does not mean a figure is unsupported; it may simply live elsewhere.
  • The total row is always the sum of the five component lines, checked by formula.
  • The same reading method applies whether the sheet ends in an FOB total or an ex-factory total.
08Workplace scenario

A buyer's assistant at Northline Apparel rejects Order A's making charge because the costing sheet shows no calculation for it

A buyer's assistant at Northline Apparel reviews Order A's finished costing sheet before approval. Seeing fabric shown with its price and consumption clearly stated, but making shown only as a single figure of USD 1.10 with no visible calculation, the assistant queries the figure, suggesting it looks unsupported compared with fabric.

Here is the line the assistant is looking at:

Order A costing sheet, making line. Cost component: Making (cutting and sewing). Order A (USD per piece): 1.10. Build-up shown on sheet: none.

Does the absence of a visible calculation mean the making charge is unsupported? Decide before opening the answer.

Show decision

No, it does not. Two facts decide this together.

First, what fabric's visible calculation actually is. Fabric happens to show its own price and consumption because both numbers are simple and commonly quoted together; this is a convenience of that particular cost component, not a rule that every line must show its own calculation.

Second, what stands behind making even without a visible calculation. Making's own USD 1.10 comes from the garment's SMV multiplied by Delta Garments' labour cost per minute, a calculation that exists in the factory's own work-study records, a separate document from the costing sheet itself.

The assistant's instinct to question an unexplained figure is reasonable practice. But the right response is to ask for the SMV and labour-rate document behind making, not to treat the absence of an on-sheet formula as proof the number is arbitrary.

09What it costs

Rejecting a properly supported figure over a missing on-sheet calculation delays an order for no real reason

Framed qualitatively, treating every unexplained lump figure as suspicious risks delaying approval of a properly costed order while a merchandiser tracks down documents that already exist. If Northline Apparel's assistant had rejected Order A's making charge outright instead of asking for its build-up, the order's approval, and Delta Garments' fabric booking that depends on it, could slip by days, pushing the whole 16-week timeline back with no cost actually saved.

A one-week delay to fabric booking on a 16-week timeline: 1 / 16 = 0.0625, about 6% of the whole production timeline lost to a question that a single document could have answered

A single request for the SMV document would have resolved the question in a day, at no cost to the timeline at all.

10Working template

Cost build-up sheet: use the driver notes to trace each of Order A's five lines back to its own numbers

Open the Cost build-up sheet workbook linked below. Its one sheet, "Cost build-up", lists Order A's five components, each with a note on how the amount is driven. Read the note beside fabric first; it names the two numbers, price and consumption, that multiply to the printed figure. Read the notes beside trims, making and overhead next; each names the kind of document that holds its own detail, without repeating that detail on this sheet. Then fill in the yellow "Your order" column with your own five numbers, asking the same questions of your own costing team for any line whose driver you cannot yet name.

11Check yourself

1. What two numbers combine to produce Order A's fabric cost of USD 1.15?

2. Why does a costing sheet usually show no visible calculation for the making charge, unlike fabric?

3. A different order's costing sheet shows trims at USD 0.55 with no itemised list. What is the correct next step before trusting that figure?
