Price, Margin and Markup: A Plain Walkthrough for Small Business Owners

⏱ 8 min read|Published 12 November 2026|By Dibyendu Choudhury

Ask ten small business owners how they set their prices and you will hear ten answers. Some look at what the neighbour charges. Some add a round figure to what the item cost them. Some pick the number that feels comfortable and hope. Almost all of them are working hard, and many of them are quietly earning less than they think, because the price on the tag was never connected to the full cost of getting the product into the customer's hands.

This walkthrough builds a price from the ground up using one simple example. The numbers are an illustration chosen to be easy to follow, not a statistic about any industry, so replace them with your own as you read. By the end you should be able to answer three questions with confidence: what does one unit really cost me, what price gives me the margin I need, and what does a discount actually cost me.

Start with the real cost of one unit

Imagine a small workshop that makes hand-bound notebooks. For one notebook, the paper, cover cloth and thread come to Rs 62. The artisan's time for that notebook is worth Rs 30. Packing and a thank-you card add Rs 8. Together that is Rs 100, and this is the direct or variable cost: the money that exists only because this notebook was made.

Many owners stop here and call Rs 100 the cost. That is the first and most common mistake, because the workshop also pays rent, electricity, a phone line, the website, insurance, repairs and the owner's own basic salary whether it makes one notebook or a thousand. These are fixed costs, and every notebook must carry a share of them or the business slowly loses money while looking busy.

Suppose the fixed costs come to Rs 30,000 a month and the workshop reasonably expects to sell 600 notebooks. Each notebook then carries Rs 50 of overhead. The full cost of one notebook is Rs 150. If you sell it at Rs 150 you have covered every expense and earned nothing for the risk, effort and growth that the business needs. That is the break-even price, and it is the floor, not the target.

A caution on the expected volume: use a cautious figure, not a hopeful one. If you divide overheads by 900 units and sell only 600, the share per unit was too small and the shortfall comes out of your pocket at month end.

Markup and margin are not the same thing

Two words cause endless confusion, so let us separate them. Markup is the amount you add on top of cost, expressed as a percentage of cost. Margin is the profit you keep, expressed as a percentage of the selling price. They sound alike and they are different numbers for the same sale.

Take our notebook. The full cost is Rs 150. If the owner wants to keep a 25 percent margin, the profit must be a quarter of the price. That means cost is the other three quarters, so the price is Rs 150 divided by 0.75, which is Rs 200. The profit is Rs 50, which is 25 percent of Rs 200. Measured the other way, Rs 50 on a cost of Rs 150 is a markup of about 33 percent.

Now see the trap. An owner who says "I add 25 percent to my cost" would charge Rs 187.50 and keep Rs 37.50, which is a margin of only 20 percent of the price. Because the two figures sit side by side in conversation, it is easy to aim for one and deliver the other. Decide which one you are using, say it aloud in your team, and write it on the pricing sheet. A useful rule: think of margin when you talk about what the business keeps, and markup when you work out the tag from cost.

Choosing a margin that is not a guess

How much margin is enough? The honest answer is the amount that lets the business pay its people fairly, survive a bad month, replace worn equipment and still grow. A rough way to find it is to work backwards. Estimate what the business needs to earn above all costs in a year for safety and growth, divide it by the number of units you expect to sell, and you have the profit needed per unit. Compare that with the profit your current prices give. If the gap is large, you have found why the business feels tight even though sales look healthy.

Different products will carry different margins. A fast-moving item may live on a thinner margin because it turns over quickly. A slow, handmade or custom item needs a thicker one because the money is tied up longer and the risk is higher. It is perfectly sound to price products differently as long as each one has been worked out, not copied from a competitor.

Look at the competition, but do not let them set your price

It is wise to know what similar products sell for. It is unwise to assume the competitor has worked out their cost correctly or shares your cost structure. They may have cheaper premises, a larger volume, or they may simply be losing money slowly and not know it. Use their price as a reference point for the customer's expectation, then check whether your cost and your target margin can live at that point. If they cannot, you have three honest choices: reduce cost without harming quality, justify a higher price with something customers value, or choose not to compete on that product.

What a discount really costs

Discounts feel generous and small. They are neither. Let us stay with the notebook at Rs 200. The variable cost is Rs 100, so every sale contributes Rs 100 towards the fixed costs and profit. Offer a 10 percent discount and the price falls to Rs 180, so the contribution falls to Rs 80, a drop of 20 percent in what each sale brings in.

To earn the same total contribution as before, you must sell more notebooks. Rs 100 divided by Rs 80 is 1.25, which means you need a quarter more sales just to stand still. If the discount does not bring at least that many extra customers, you have worked harder for less. A larger discount makes the arithmetic harsher: the thinner the contribution, the bigger the jump in volume you need.

This does not mean never discount. A discount can clear old stock, reward a loyal customer, or open a new relationship. It means you should know the price of the offer before you announce it. Before any sale, calculate the extra units needed and ask whether that is believable. If it is not, consider a different kind of offer, such as a small free add-on that costs you little but feels valuable to the customer.

Do not forget channel fees, taxes and payment costs

Selling through an online marketplace, a delivery app or a payment gateway adds charges that quietly eat the margin. Suppose a marketplace takes 15 percent of the selling price and you also pay for shipping and returns. On a Rs 200 notebook that is Rs 30 gone before you pack the parcel, which cuts the Rs 50 profit to Rs 20, before shipping. The same notebook that earned a healthy margin in your shop may barely break even on the marketplace.

The answer is to build a separate price for each channel, or to be clear which channels exist to bring customers and which exist to earn profit. Treat taxes carefully as well. Decide whether the price on your tag is inclusive of tax or not, apply it the same way every time, and confirm the treatment for your products with your accountant, because getting it wrong in either direction costs real money.

A one-page pricing sheet

Put everything above on one page per product. Write down the direct cost per unit, the overhead share per unit using a cautious volume, the break-even price, the target margin, the resulting price, and the price after each channel's fees. Add a line for the largest discount you are willing to give and the extra volume it needs. When a supplier raises a price or rent changes, update the sheet the same week, and review every price at least twice a year even if nothing seems to have changed.

Small changes compound. A business that reviews its prices regularly tends to notice a rising cost early and pass it on gently, instead of discovering a year later that it has been subsidising its customers. Price is the one lever that changes profit immediately, without more advertising, more stock or more hours.

One exercise for this week

Pick your best-selling product and work out its full cost per unit, including a fair share of overheads. Then compare it with your price and compute the margin you are actually keeping. If the number surprises you, you have learned something valuable for the price of an hour. Tell me in the comments what you found, and which product you will re-price first.
