Two Percent Off Purchases or Five Percent More Sales: An MT436 Unit 1 Discussion Post on Purchasing and Profit
MT436 · Unit 1 Discussion Board Post
Posted by [Student Name]
Marsh Run Utility Vehicles and its income statement are composite; the sources cited are real.
Initial Post
I work in accounts payable at Marsh Run Utility Vehicles, a composite Muscatine, Iowa, maker of work utility vehicles sold to farms, ranches and utility crews. Last year it sold 2,900 vehicles for revenue of $93.96 million. Purchased materials and components, from engines to seats to wiring, were 54.9 percent of revenue, about $51.6 million. Net profit was 6 percent of revenue, about $5.64 million.
Our textbook makes the familiar argument that purchasing savings go straight to profit (Monczka et al., 2021). The arithmetic is simple. Two percent of $51.6 million is about $1,032,000, which would raise net profit by about 18.3 percent.
The usual next step is to ask what sales increase would add the same profit. Dividing $1,032,000 by the 6 percent net margin gives about $17.2 million, more than an 18 percent jump in sales. That comparison makes purchasing look extraordinary.
A dollar saved in purchasing is worth about four and a half dollars of new sales here, not seventeen.
But I think the net margin is the wrong divisor. A new vehicle sale does not earn the average net margin; it earns its contribution margin, because overhead, the plant and the office already exist. For Marsh Run, contribution after materials, direct labor and freight is about 22 percent of revenue. Dividing $1,032,000 by 22 percent gives about $4.69 million of extra sales, about 5.0 percent more revenue. That is still a strong case for purchasing, but it is a fair one.
What price savings leave out is the other point. A two percent price cut that comes with longer lead times, weaker quality or a supplier that cannot grow with us could cost more than it saves. Ellram and Siferd (1993) argued for judging purchases on total cost of ownership rather than price, and the units ahead will put that idea to work on real quotes. So I would ask: in your own organization, which divisor would you use, and what would a price saving have to bring with it to count?
Reply to Priyanka
Priyanka, your software company is an interesting test because its purchases are such a small share of revenue. If purchases are 15 percent of sales and contribution margin is 80 percent, a two percent purchasing saving would equal only about 0.4 percent more sales. That suggests the textbook argument is strongest in manufacturers like Marsh Run and weakest in companies like yours. Does your company's purchasing team focus on price at all, or more on contract terms and risk?

Reading the MT 436 Unit 1 instructions
The opening MT436 discussion asks students to show how purchasing affects profit, usually by comparing a purchasing saving with the sales increase that would add the same profit. Instructors expect the arithmetic shown in a few lines, from revenue, purchases as a share of revenue and margins. The choice of divisor deserves care: dividing by net margin overstates the sales equivalent, because a new sale earns its contribution margin, not the average net margin. A good post names that choice and defends it. It should also say what a price saving can leave out, such as quality, delivery or supplier stability. Close with a question about which margin classmates would divide by, and the 140-word reply should rerun the numbers for someone else's company.
How the MT 436 Unit 1 example is put together
Revenue, purchases and margin for the vehicle maker come first in the sample. The second applies the textbook argument and computes the saving's share of profit, citing Monczka and colleagues. The third gives the common net-margin comparison and its large result. A highlighted line restates the fair ratio. The fourth paragraph argues for contribution margin and computes the smaller, honest equivalent. The last paragraph turns to what price alone misses, citing Ellram and Siferd on total cost of ownership, and asks classmates which divisor they would use. The reply to Priyanka runs the numbers for a software company with small purchases and high margins and asks what its buyers focus on.
MT436 Unit 1 rubric: what earns full points
Opening discussion posts in this course are commonly judged on whether the arithmetic is shown and whether the comparison is fair. Rubrics reward a calculation a classmate could reproduce from stated figures. Credit goes to recognizing that the sales equivalent depends on the margin used and defending the choice. Mentioning what price savings can leave out shows the student is ready for total cost thinking. Overstating the effect with the net-margin divisor, without comment, tends to cost analysis marks. A reply earns credit by applying the comparison to a different kind of business. Graders also look for the course text and a total cost source in APA 7.
Common MT436 Unit 1 mistakes, and how to avoid them
Many first posts repeat the textbook claim that purchasing savings are worth many times their value in sales, without any figures. Another common error divides by net margin and presents an inflated sales equivalent as fact. Students often forget that new sales bring new purchases with them, which is why contribution margin is the better divisor. Some posts treat any price cut as pure gain, ignoring quality or delivery effects. Replies tend to agree that purchasing matters. Before posting, compute your sales equivalent twice, once with net margin and once with contribution margin. If you report only the first, say why; if you report both, explain which one a manager should believe.

MT436 Unit 1 questions, answered
Why use contribution margin instead of net margin?
Because extra sales bring extra variable costs, materials and direct labor among them, while fixed costs mostly stay put. Contribution margin measures what each added sale actually leaves after those costs. For the example's builder it is twenty-two percent against a net margin of six, so the sales increase needed to match a saving falls to about a quarter of the textbook figure.
Does the post need outside sources?
Usually at least one beyond the course text, since discussion rubrics often credit sources separately. A trade article on industry margins or a published annual report serves well. The example cites the course text and builds its composite income statement in the open, labeling every figure as illustrative rather than passing it off as a real company's data.
Where can I find a free MT436 Unit 1 sample paper?
The full MT436 Unit 1 post is on this page, comparing a two percent purchasing saving with the sales growth that would earn the same profit.
Why does the MT436 Unit 1 sample divide by contribution margin?
A new vehicle sale brings its own materials and labor, so it earns the 22 percent contribution margin, not the 6 percent net margin.
How does purchasing affect profit in the MT436 Unit 1 sample?
Every dollar saved on purchases goes straight to profit, so 2 percent of $51.6 million adds about $1.03 million, about 18.3 percent of net profit.
