Lecture: Who Buys and at What Price: Marketing, Products & Pricing
Lecture script · about 15–20 minutes spoken · Week 7
Opening
Think about the last time a price made you stop. Maybe a sandwich cost a dollar more than you expected, or a plan you liked added a cheaper tier with ads. You noticed. Maybe you changed what you bought. In that moment you were somebody's market, reacting to somebody's pricing decision.
Whether you end up running a gym's front desk, stocking a bookstore, driving for a ride-share app, or selling coffee from a cart of your own, you'll need three answers. Who are your buyers? What price covers your costs? And how many sales does it take before you earn a profit?
Here's where we are. In Week 2, The Market It Sells Into: Economics for Business, we placed the coffee cart in monopolistic competition, with many sellers and each drink a little different. In Week 3, From Idea to Plan: Entrepreneurship, Small Business & the Business Plan, the cart took a 10,000-dollar loan, and the first year's interest came to 1,000 dollars. And in Week 6, Making the Product: Operations, Quality & Information Systems, we found the cart can make at most 30 drinks an hour.
In this lecture we start with the customer, choose whom to serve, build the cart's marketing mix, separate products from services, follow a product's life, and then run the cart's numbers.
1. Listen first, sell second
Let's start in an illustrative neighborhood bike shop having a slow month. The owner's first thought is flyers. Instead, the owner asks riders what they need. Many ride to work, and they say the same thing: repairs only happen while they're at their desks.
So the shop opens early two mornings a week for quick repairs before work. It hasn't spent a dollar on ads. But commuters start telling each other, because the shop now offers something they wanted and the shop down the street doesn't.
That's the big idea behind marketing. Here's the term. The marketing concept is the idea that a business should find out what customers want and deliver it better than its rivals do, while still earning a profit.
Notice the three parts. It starts with the customer. It compares the business with its rivals. And it has to pay. An offer that pleases everyone but loses money on every sale isn't the marketing concept at work.
A lot of people hear "marketing" and think of ads. But the shop's best marketing move was a change in its hours, made before any ad ran.
Pause and try this. Was the bike shop's early opening a marketing decision or a change in operations?
Think about where the idea came from.
Here's the answer. It was a marketing decision, because it started from what customers said they wanted and was built to beat rivals at a profit.
Telling people about it comes later.
2. Split, then choose
Now picture an illustrative community gym that tries to please everyone. Same classes, same times, same loud music. Retirees find it too loud, and nurses on early shifts find no class before work. By trying to serve everyone, it serves no one especially well.
A business does better when it chooses. A target market is the particular group of buyers a business decides to serve and builds its offer around. And to choose, a business first splits its market. Market segmentation is splitting a whole market into smaller groups of buyers who share a trait, so a business can choose which groups to serve and how.
There are four common ways to split. Geographic segmentation is grouping buyers by where they live or work, such as a neighborhood, a city, or a region. Demographic segmentation is grouping buyers by measurable traits such as age, life stage, household size, or income. Psychographic segmentation is grouping buyers by their lifestyle, values, and interests rather than by measurable traits. And behavioral segmentation is grouping buyers by how they use a product, how often they buy it, and what benefit they want from it.
For the gym, that might be people within a short drive, retirees, people who want exercise to feel social, and members who come at the same early hour every day. The gym picks retirees who want a social midday class, and builds a class around them.
Then you want to know how those buyers decide. Buyer behavior is how and why people decide what to buy, from noticing a need through comparing options, buying, and judging the purchase afterward. A shopper in an illustrative independent bookstore notices they need a gift, compares two novels and a cookbook, buys one, and later judges it. Every step is a chance to help or lose the sale.
Pause and try this. "Members who come at the same early hour every day, before work." Which segmentation base is that?
Ask yourself what the group has in common.
Here's the answer. It's behavioral, because the group is defined by how and when they use the gym, not by age or where they live.
The biggest market isn't automatically the best target. Split first, then choose.
3. Place is the path, not the pin
Picture the cart on a weekday morning, parked outside the new office building two blocks away. Every part of that scene is a choice: what it sells, what it charges, where it parks, and how people find out.
The marketing mix is the set of decisions a business controls in bringing an offer to market, conventionally organized as the four Ps. The four Ps are the four parts of the marketing mix: product, price, place, and promotion. That framework comes from McCarthy, in 1960, in a book called Basic Marketing. Some courses add more Ps for services, like people, process, and physical evidence. Conventions differ, and in this course we use the four.
Here's the cart's mix. The product is espresso drinks made to order. The price is 5 dollars a drink. Place is where it gets interesting. The cart goes to the office building on weekdays and to the farmers' market on weekends. And promotion, how the word gets out, gets its own week in Week 9, Reaching More Customers: Distribution, Promotion & Digital Commerce.
Now, about place. Place, in the marketing mix, is every decision about how the offer reaches the buyer, including where, when, and through whom it is sold, not only a store's address. A café has one address; the cart picks its place every morning.
Pause and try this. The cart moves to the farmers' market on weekends. Which of the four Ps is that decision?
Think path, not pin.
Here's the answer. It's place, because it decides when and where the drink reaches the buyer.
A place decision can change by the day of the week.
4. Can you put it on a shelf?
Here's a quick story. A market stall roasts coffee beans on a slow afternoon. Nobody buys that day, and that's fine: the bags sit on the shelf and sell later.
Across town, an illustrative ride-share driver crosses the city with an empty back seat. That seat can't be saved for the evening rush.
That's the difference between a good and a service. A service is an offer that is produced and used at the same moment, such as a haircut or a ride, so it cannot be made ahead and stored. A good, like the bag of beans, can be made ahead and kept on a shelf.
So a service business has to match what it can provide to what buyers want, hour by hour, because unsold time doesn't keep.
The cart is a bit of both. Each drink is a good, but an empty hour at the machine is lost the way the driver's empty seat is.
Pause and try this. A haircut or a bag of coffee beans: which one is the service?
Ask the shelf question.
Here's the answer. The haircut, because it's produced and used at the same moment and can't be stored.
If it can't sit on a shelf, it's a service.
5. New, catching on, leveling off, fading
Picture an illustrative phone accessory, a charging case made for one phone model. At first, hardly anyone has heard of it. A year later, every store sells one and rivals have copied it. Then the phone model is replaced, and sales fade.
That shape has a name. The product life cycle is a classroom model of a product's sales over time in four stages: introduction, growth, maturity, and decline. In introduction, the product is new and sales are low. In growth, sales climb fast and rivals show up. In maturity, most people who want it already have it, sales level off, and rivals fight on price. In decline, buyers move on and sales fall.
An illustrative streaming plan that most households in its market already have, with sign-ups leveled off and rivals competing on price, is in maturity.
I want to be honest about this one. The life cycle is a model, not a timetable. Some products sit in maturity for decades, and some go from introduction straight to decline. So you place a product by what its sales and its rivals are doing, not by its age.
Pause and try this. The charging case's sales are climbing fast and rival cases are appearing. Which stage is it in?
Look at the sales trend and the rivals.
Here's the answer. It's in growth, because sales are rising fast and competitors are arriving.
When the phone model is replaced and sales fall, the same case is in decline.
6. Divide by what each sale leaves over
Now the numbers. Picture the cart's owner on opening morning. The permit is paid, the insurance is paid, and the loan's interest is due whatever happens. None of that changes whether the cart sells a few drinks or a long line's worth. But every drink uses a cup, a lid, beans, and milk.
Those are two kinds of cost. A fixed cost is a cost that stays the same however many units a business sells in a period, such as rent, insurance, or loan interest. A variable cost is a cost that rises with every unit sold, such as the cup, lid, beans, and milk in each drink.
For the cart, the fixed costs are the plan's 35,000 dollars of operating expenses plus the loan's 1,000 dollars of interest. That's 36,000 dollars a year. The variable cost is 2 dollars a drink. The price is 5 dollars.
So each drink sells for 5 dollars, but 2 of those dollars go straight to the cup and what's in it. That leaves 3 dollars. The per-unit margin is the price of one unit minus its variable cost: the dollars each sale contributes toward covering fixed costs.
Now the big one. The break-even point is the number of units a business must sell to cover all its costs, found as fixed costs divided by the price minus the variable cost per unit. For the cart, that's 36,000 dollars divided by 3 dollars a drink, which is 12,000 drinks a year. Spread over 250 operating days, that's 48 drinks a day. And 12,000 drinks at 5 dollars each is 60,000 dollars of revenue.
Said plainly: the cart has to sell about 48 drinks a day before it earns a single dollar of profit. At 30 drinks an hour, that's less than two hours of full-speed work, so the hard part is finding the buyers.
One honest caveat. A break-even assumes one price and a steady variable cost. Real carts run specials, and bean prices move, so the owner reruns the numbers whenever something changes.
Here's the classic mistake. People divide the fixed costs by the price, 36,000 by 5, and get 7,200 drinks. That number is too low. Only 3 dollars of each sale is left over to cover fixed costs, not 5.
Pause and try this. Why is 7,200 drinks the wrong break-even for the cart?
Think about where the other 2 dollars go.
Here's the answer. Dividing by the 5-dollar price ignores the 2-dollar variable cost, so only the 3-dollar per-unit margin covers fixed costs, and 36,000 divided by 3 is 12,000.
At 7,200 drinks, the cart would still be losing money.
7. One gap, two percentages
Imagine two people talking about the same drink. One says, "We mark it up 150 percent." The other says, "Our margin is 60 percent." It sounds like an argument. But they're describing the same 3-dollar gap.
The difference is what each one divides by. Markup on cost is the gap between price and cost stated as a percentage of the cost: price minus cost, divided by cost, times 100. Margin on price is the gap between price and cost stated as a percentage of the price: price minus cost, divided by price, times 100.
For the cart, the gap is 5 minus 2, which is 3 dollars. Divide 3 by the 2-dollar cost and multiply by 100, and you get a markup of 150 percent. Divide the same 3 by the 5-dollar price and multiply by 100, and you get a margin of 60 percent. The markup is bigger because it divides by the smaller number.
Why care? If a manager wants a 60 percent margin and a new hire applies a 60 percent markup instead, every price comes out too low.
Pause and try this. For the cart, which is larger, the markup on cost or the margin on price?
Ask yourself which number each one divides by.
Here's the answer. The markup, at 150 percent versus a 60 percent margin, because it divides the 3-dollar gap by the 2-dollar cost instead of the 5-dollar price.
So before you trust any percentage, ask: a percentage of what?
8. Cut the price, raise the bar
Last idea. Picture two launches. The charging case comes out at a high price for its most eager buyers, and the price drops over the following months. The streaming plan launches at a very low price to sign up households fast.
Those are the two classic launch strategies. Price skimming is launching a new product at a high price to the buyers most eager for it and cutting the price over time. Penetration pricing is launching a new product at a low price to build sales volume and market share fast.
Which one works depends on how buyers react. Price sensitivity is how strongly buyers change the amount they buy when the price changes, and in this course we describe it in words and never compute it. Office workers two blocks from their desks might barely react to a small price change. Shoppers at the farmers' market, with a chain café in sight, might react a lot.
Now watch what a lower price does to the cart. Say the cart opens at 4 dollars instead of 5. Fixed costs stay at 36,000. The variable cost stays at 2. So each drink now leaves 4 minus 2, which is 2 dollars. And 36,000 divided by 2 is 18,000 drinks a year.
That's 18,000 versus 12,000, one and a half times as many drinks, before the cart earns any profit. So a penetration price is a bet. It pays only if the lower price brings in at least 6,000 more drinks a year. Whether buyers react that strongly is the price-sensitivity question, and no formula answers it for you.
Pause and try this. Does a 4-dollar price raise or lower the cart's break-even, and why?
Recompute what each drink leaves over.
Here's the answer. It raises the break-even, from 12,000 to 18,000 drinks, because each drink now contributes 2 dollars instead of 3.
A cheaper drink may be easier to sell, but the cart has to sell more of them.
Closing
Let me pull it together in the order we built it. The marketing concept starts with what customers want, beats rivals at it, and stays profitable, so marketing is much more than ads. Segmentation splits a market by where buyers are, who they are, what they value, or how they use the product, and the target market is the group you choose. The four Ps are product, price, place, and promotion, and place is the whole path to the buyer. A service is produced and used at the same moment, so it can't be stored. The product life cycle runs introduction, growth, maturity, and decline, as a model and not a timetable. The cart's break-even is 12,000 drinks a year, about 48 a day, because each drink leaves 3 dollars toward 36,000 dollars of fixed costs. That same 3-dollar gap is a 150 percent markup and a 60 percent margin. And a 4-dollar penetration price raises the break-even to 18,000 drinks.
Next in this module come the slide deck, the Readings and Resources page, the lecture tutorial, the practice set, and the quiz. Then, in Week 8, Midterm Review & the Growth Question, we gather the tools from Weeks 1 to 7 and ask what changes when one cart becomes two.
