Factoring Factory Profit Margin & Risk Buffer Percentages
1. Margin Is a Percentage of the Cost Base
Every margin figure in this lesson is a percentage of the cost base, which is the total cost before profit. That definition must be stated on every sheet, because the other common definition, margin on price, gives a different number and the two are constantly confused. On the woven casual shirt cost base of BDT 654.00 per garment, a 10 percent margin on cost is 654.00 multiplied by 0.10, which is BDT 65.40 of profit, and the FOB price is 654.00 plus 65.40, which is BDT 719.40. A 10 percent margin on price would be 10 percent of the BDT 719.40 selling price, which is BDT 71.94, a figure BDT 6.54 higher per garment. A merchandiser who quotes on one base and reports on the other overstates the margin on every order.
Build the margin ladder before negotiating, so the price consequence of each margin level is visible. At 5 percent, profit is 654.00 multiplied by 0.05, which is BDT 32.70, and the FOB price is 654.00 plus 32.70, which is BDT 686.70. At 10 percent, profit is BDT 65.40 and the price is BDT 719.40. At 15 percent, profit is 654.00 multiplied by 0.15, which is BDT 98.10, and the price is 654.00 plus 98.10, which is BDT 752.10. Order profit follows by multiplying by 10,000: BDT 327,000 at 5 percent, BDT 654,000 at 10 percent, BDT 981,000 at 15 percent. The ladder turns a negotiation about margin into a negotiation about price, which is what the buyer actually pays.
2. The Risk Buffer Sits on Its Own Line
A risk buffer is a separately labelled percentage added to the cost base to absorb the things that will go wrong: a fabric surcharge, a rework lot, an extra inspection. It is not profit, and it must never be merged into the profit line, because a merged buffer cannot be tracked. At a 2 percent buffer on the shirt, the buffer is 654.00 multiplied by 0.02, which is BDT 13.08. The buffered cost is 654.00 plus 13.08, which is BDT 667.08. Profit is then calculated on the buffered cost: 667.08 multiplied by 0.10 is BDT 66.708, rounded half-up to BDT 66.71. The buffered FOB price is 667.08 plus 66.71, which is BDT 733.79 per garment.
If nothing goes wrong, the buffer becomes extra margin and the factory earns BDT 733.79 against a true cost of BDT 654.00, which is BDT 79.79 of profit. If a surcharge of BDT 13.00 per garment arrives, the buffer absorbs it and the profit line of BDT 66.71 survives untouched. Without the buffer, the same surcharge comes straight out of a BDT 65.40 profit line and leaves BDT 52.40. The buffer costs one row on the sheet and protects the whole order, but only if it is labelled, tracked, and set by policy rather than invented per order.
3. Stress Test: What an Overrun Does to a Quoted Margin
A quoted margin is a promise made before production. A realised margin is what survives production. The stress test bridges the two by raising the cost base and holding the quoted price fixed. At the 10 percent quoted price of BDT 719.40, a 5 percent cost overrun raises the cost from BDT 654.00 to 654.00 multiplied by 1.05, which is BDT 686.70. Realised profit is 719.40 minus 686.70, which is BDT 32.70 per garment. The margin has halved: from BDT 65.40 to BDT 32.70, which is 5 percent of the original cost base, not 10 percent.
A 10 percent overrun reaches break-even exactly: cost becomes 654.00 multiplied by 1.10, which is BDT 719.40, and realised profit is 719.40 minus 719.40, which is BDT 0.00. Any overrun beyond 10 percent turns the order into a loss. That is the arithmetic behind every thin-margin disaster: a factory that quotes 6 percent margin breaks even at a 6 percent overrun, and garment production overruns of 6 percent are common, not exceptional. The stress test belongs on the quotation template, not in hindsight, because a price that fails the test should never be sent.
4. Claims and Penalties Consume Margin Line by Line
Cost overruns are not the only margin eater. Claims and penalties are deducted from the order value, and they consume margin just as directly. Take a 2 percent short-shipment penalty on the shirt order: 0.02 multiplied by the order value of BDT 7,194,000 is BDT 143,880. Order profit falls from BDT 654,000 to 654,000 minus 143,880, which is BDT 510,120. Per garment, 510,120 divided by 10,000 is BDT 51.012, rounded half-up to BDT 51.01, against a quoted profit of BDT 65.40. The penalty alone removed BDT 14.39 per garment, which is more than a fifth of the quoted margin.
Combine the two events and the picture darkens further. A 5 percent overrun plus a 2 percent penalty leaves a cost of BDT 686.70 and a penalty of BDT 14.39 per garment against a price of BDT 719.40, giving a realised profit of 719.40 minus 686.70 minus 14.388, which is BDT 18.312, rounded half-up to BDT 18.31 per garment, or BDT 183,120 on the order (the order figure comes from the unrounded 18.312, which is why it differs by BDT 20 from 18.31 multiplied by 10,000). The order is still profitable, but barely, and only because the quoted margin was 10 percent. At a 6 percent quoted margin the same combination would be a loss. The stress test table in this lesson shows all five scenarios side by side, and it is the table a factory owner should ask for before approving any quotation.
5. The Minimum Margin Rule
The minimum margin rule turns the stress test into policy. Margin must exceed the known per-garment costs it has to cover, or the order is priced to lose money on a bad day. On the shirt order, the known bank cost from the previous lesson is BDT 24.77 per garment, and the risk buffer is BDT 13.08 per garment. Their sum is 24.77 plus 13.08, which is BDT 37.85 per garment. Divide by the cost base: 37.85 divided by 654.00 is 0.05787, or 5.79 percent. Any margin below 5.79 percent on this order does not cover the bank cost and the buffer together, and any margin above it leaves a cushion of 65.40 minus 37.85, which is BDT 27.55 per garment at the 10 percent quoted margin.
Set the rule as factory policy, approved by management, with a signature requirement for any quotation below the minimum. A denim factory in Gazipur learned the alternative the hard way: a 6 percent margin quoted for volume, a fabric surcharge and a 2 percent penalty in the same order, and a closed order below break-even even though every department met its own target. The factory now quotes at a policy margin of 10 percent with a 2 percent buffer, and no quotation below the minimum leaves the building without a director signature. Volume orders still get a competitive price, but the price now carries the buffer that absorbs the surcharge and the penalty that used to erase the margin.
6. Margin on Cost Versus Margin on Price, Once More
The confusion between the two bases deserves a final worked comparison, because it recurs in every costing department. Cost base BDT 654.00, quoted price BDT 719.40, profit BDT 65.40. Margin on cost is 65.40 divided by 654.00, which is 0.10, or 10 percent. Margin on price is 65.40 divided by 719.40, which is 0.0909, or 9.09 percent. The same profit is 10 percent on one base and 9.09 percent on the other. A manager who hears 10 percent and assumes it is on price will think the factory earned BDT 71.94 per garment when it earned BDT 65.40, and will approve the next quotation on a margin that does not exist.
State the base on the sheet, in words, next to the margin line: profit at 10 percent of cost. Three words prevent the error. Omit them and the error will happen, because the next person to read the sheet will assume the base that flatters their own report.
7. Quoted Margin Versus Realised Margin
The final discipline is monthly review. For every closed order, compare the quoted sheet against actual costs, block by block, and record the realised margin next to the quoted margin. The gap between the two is the factory most honest report: it shows whether fabric, CM, commercial costs, bank charges, or claims caused the variance, and it shows whether the buffer was used, unused, or exceeded. A factory that reviews realised margin monthly learns its true overrun rate within a season, and can set its buffer from evidence instead of habit.
A factory that never reviews realised margin keeps quoting the same margin into the same overruns, and wonders why profitable quotations become unprofitable orders. The sheet is not the end of costing. The closed order is, and the realised margin is the number that tells the truth about both.
8. Summary and Checklist
Margin is a percentage of the cost base, the buffer is a separate percentage on the same base, and the quoted price must survive an overrun and a claim. Build the ladder, add the buffer openly, stress-test at 5 and 10 percent overrun, deduct expected claims, and check the minimum margin rule. A price that passes all five tests is a price the factory can defend in a negotiation and survive in production, and a factory that reviews realised margin monthly will keep it that way.

| Margin on cost | Profit per garment (BDT) | FOB price per garment (BDT) | Order profit on 10,000 pieces (BDT) |
|---|---|---|---|
| 5 percent | 32.70 | 686.70 | 327,000 |

| Scenario | Cost per garment (BDT) | Realised profit per garment (BDT) | Order profit (BDT) |
|---|---|---|---|
| No overrun, no claim | 654.00 | 65.40 | 654,000 |
| 5 percent cost overrun | 686.70 | 32.70 | 327,000 |
| 10 percent cost overrun | 719.40 | 0.00 | 0 |
| 2 percent short-shipment penalty | 654.00 | 51.01 | 510,120 |
| 5 percent overrun plus 2 percent penalty | 686.70 | 18.31 | 183,120 |
Practical Commercial Flow
The shirt cost base of BDT 654.00 per garment. At 5 percent margin the FOB price is BDT 686.70, at 10 percent it is BDT 719.40, and at 15 percent it is BDT 752.10. With a 2 percent risk buffer the cost becomes BDT 667.08 and the 10 percent price becomes BDT 733.79. If costs overrun 5 percent to BDT 686.70 while the price stays at BDT 719.40, realised profit falls to BDT 32.70 per garment.
Factory Real-Life Scenario
Scenario: A denim factory in Gazipur quoted jeans at a 6 percent margin because the buyer promised volume, and the merchandiser set the margin without management approval. A fabric surcharge and a 2 percent short-shipment penalty arrived in the same order, and the order closed below break-even even though every department met its own target.
Solution: Management set a written margin policy: minimum 10 percent margin on cost, a 2 percent risk buffer on every order, and no quotation below the minimum without a director signature. The next volume order was quoted at the policy margin and the buyer accepted, because the factory could show the buffer and margin lines openly.
Impact: The factory has not closed an order below break-even since the policy was set. Volume orders still get a competitive price, but the price now carries the buffer that absorbs the surcharge and the penalty that used to erase the margin.
Commercial Officer Best Practice
Review realised margin every month by comparing quoted sheets against closed orders, block by block. The gap between quoted margin and realised margin is the factory most honest report on where money is actually lost.
Top Beginner Mistakes to Avoid
- Confusing margin on cost with margin on price, which overstates the margin by the margin itself.
- Setting margin per order by negotiation instinct instead of factory policy, so the factory has no minimum margin at all.
- Merging the risk buffer into profit, so nobody knows whether the buffer is still available when a problem arrives.
- Quoting a thin margin for volume and then absorbing a surcharge and a penalty that together exceed the margin.
- Measuring margin only at quotation and never comparing it with realised margin on closed orders.
Important Commercial & Trade Terminology (5 Terms)
Profit expressed as a percentage of the cost base before profit. A 10 percent margin on a BDT 654.00 cost is BDT 65.40 of profit.
💡 Note: This lesson always uses margin on cost, never margin on price, unless stated otherwise.Profit expressed as a percentage of the selling price. Ten percent of the BDT 719.40 selling price is BDT 71.94, which is a larger figure than the same percent on cost.
💡 Note: Mixing the two bases is the most common margin error in costing.A separately labelled percentage added to the cost base to absorb cost overruns, distinct from profit and set by factory policy.
💡 Note: The buffer protects profit. It is not profit itself.The margin actually earned on a closed order, calculated from actual costs and actual deductions, as opposed to the quoted margin on the sheet.
💡 Note: The gap between quoted and realised margin is the factory variance report.The price at which the order covers all costs including the buffer, with zero profit. For the shirt at a 10 percent quoted margin, a 10 percent cost overrun reaches break-even exactly.
💡 Note: Any overrun beyond break-even turns the order into a loss.Interview Preparation Questions & Answers (4 Questions)

Key Takeaways & Summary Points
Executive Lesson Summary
Margin is a percentage of the cost base, the buffer is a separate percentage on the same base, and the quoted price must survive an overrun and a claim. Build the ladder, add the buffer openly, stress-test at 5 and 10 percent overrun, deduct expected claims, and check the minimum margin rule. A price that passes all five tests is a price the factory can defend in a negotiation and survive in production.
