Markup / Margin Calculator

How to use the markup / margin calculator

Enter what an item costs you, then pick how you want to set the price. By markup percent adds a percentage on top of your cost. By margin percent targets a percentage of the selling price as profit. By price lets you type a price and see what markup and margin it implies.

Whichever you choose, the tool returns all four numbers at once, which is the whole design: selling price, profit in dollars, markup percent and margin percent, so the same deal is visible from every angle simultaneously. The defaults are a $60.00 cost at a 50 percent markup, which prices at $90.00 with $30.00 of profit.

Anchor on that example, because it contains the entire lesson. The $30.00 of profit is a 50 percent markup, because it is measured against the $60.00 cost, and simultaneously a 33.3 percent margin, because the same $30.00 is measured against the $90.00 price. One profit, two percentages, and neither is wrong.

Markup is the natural language of buying, since it describes what you added to what you paid, while margin is the natural language of accounting, since an income statement reports profit as a share of revenue. Cost is always the smaller number, so the markup percentage is always the larger of the two, and they only coincide at zero.

Use the by price mode to reverse-engineer a number someone else set. Drop in your cost and a competitor’s price, or a price a buyer has proposed, and you will see immediately what markup and margin are baked into it. That is the fastest way to check whether a quoted deal clears the margin your business needs before you agree to it, and it works just as well on your own historical pricing as on anyone else’s.

Pricing to a target margin

The reason this matters commercially is that pricing off the wrong one silently destroys profit and nothing in the transaction flags it. Suppose you need a 40 percent margin. The correct price is cost divided by one minus the margin, and that price happens to represent a 66.7 percent markup.

If instead you add 40 percent to cost, you price at $84.00 and earn a 28.6 percent margin, missing the target by more than eleven points and by $16.00 a unit. Sell a thousand units and the mistake is $16,000.00 of gross profit that never existed.

The formula, worked line by line

Set the price from a markup or from a margin, and the profit and both percentages fall out of it. Markup divides profit by cost; margin divides the same profit by price. Every disagreement about pricing percentages traces back to those two denominators and nothing else.

The two conversion formulas are worth memorising in both directions, because they are what let you translate a supplier’s markup into the margin your accountant will report, and a target margin into the price you actually have to charge. Margin equals markup divided by one plus markup; markup equals margin divided by one minus margin.

from markup:  price = cost × (1 + markup% ÷ 100)
from margin:  price = cost ÷ (1 − margin% ÷ 100)
profit = price − cost
markup% = profit ÷ cost × 100      margin% = profit ÷ price × 100

Worked example with the defaults, a $60.00 cost at a 50 percent markup: price = 60 × 1.50 = $90.00 and profit = 90 − 60 = $30.00. Measured against the $60.00 cost that profit is a 50 percent markup; measured against the $90.00 price the very same $30.00 is a 33.3 percent margin.

The same dollars are always a larger percentage as markup than as margin, because cost is the smaller base. Doubling cost makes the point sharply: selling that $60.00 item at $120.00 is a 100 percent markup but only a 50 percent margin, and no markup, however large, ever reaches a 100 percent margin.

Two caveats on what these numbers mean. First, this is gross margin on a single unit, so it says nothing about rent, wages, payment processing, returns or advertising, and a healthy-looking gross margin can still sit above a loss-making business.

Second, cost here is whatever you enter, so a landed cost including freight and duty tells a very different story from a bare invoice price, and comparing your margin against anyone else’s is only meaningful if both were computed on the same basis.
