Markup Calculator

How to Use the Markup Calculator

Markup is how most trades actually price: take what it cost you, add a percentage, sell. This calculator does that in all three directions — markup to price, target margin to price, or an existing price back to both percentages — and prints the conversion table that stops the two being confused.

1. Enter the unit cost. Landed cost, not the invoice price: include freight in, duty and anything else you pay to get the item onto your shelf. Leaving those out is the most common reason a markup that looks healthy is not.
2. Choose where you are starting from. The toggle switches between markup, target margin and a known selling price. Whichever you pick, the other two are calculated for you.
3. Enter the figure for that mode. A 65% markup, a 40% target margin, or a price of $70.13 — the calculator resolves all three views of the same sale.
4. Add the batch size to scale the per-unit profit up to a whole order. Useful when negotiating a purchase, because it turns a percentage argument into a money argument.
5. Read the conversion table. Eight common markups, each with the price it produces and the margin it really represents.

The single most useful fact on this page: a 50% markup is a 33.33% margin. If those two numbers feel like they should be closer together, the table below is worth a slow read.

Markup and Margin Formulas

Three formulas, one relationship. Markup and margin describe the same profit from opposite ends.

Cost-plus pricing has one real weakness: it prices from your costs rather than from what the customer will pay. It is a sensible floor and a poor ceiling. Use it to make sure a price is not too low, then check the market before deciding it is right.

Example

A $42.50 cost at a 65% markup

1. Price: 42.50 × 1.65 = $70.13 (70.125 before rounding).
2. Profit per unit: 70.13 − 42.50 = $27.63.
3. Margin: 27.63 ÷ 70.13 × 100 = 39.39% — noticeably below the 65% markup.
4. On a batch of 500: revenue $35,062.50, cost $21,250, profit $13,812.50.
5. To reach a 40% margin instead: 42.50 ÷ 0.60 = $70.83, a 66.67% markup.
6. So a 65% markup and a 40% margin are almost the same price here — 70 cents apart — which is exactly why the two get mixed up.

Where the confusion costs real money

Now try it at the other end of the range. A trade that works on a 20% margin needs a 25% markup: 42.50 ÷ 0.80 = $53.13. Someone applying a 20% markup instead charges $51.00 and earns a 16.67% margin. That is $2.13 per unit, or $1,062.50 across 500 units, given away by using the wrong denominator.

Working backwards from a price

Suppose a competitor sells the same item at $59.50. Set the toggle to price and the calculator returns a 40% markup and a 28.57% margin on your $42.50 cost. That tells you immediately whether matching them is viable: at 28.57% you keep $17.00 a unit, and the question becomes whether $17.00 covers your share of overheads — which is a break-even question, not a pricing one.

Why the Two Percentages Diverge

Every common markup on a $42.50 cost, with the margin it actually delivers.

The gap between the two columns widens all the way up. At a 20% markup the margin is 3.33 points lower; at 150% it is 90 points lower. Any rule of thumb that treats them as roughly interchangeable breaks down almost immediately.

Different trades settle on different conventions, and knowing which one someone is using matters more than the number itself. Wholesale and distribution generally talk in markup because they buy and resell. Retail and manufacturing generally talk in margin because they report against revenue. When a supplier and a buyer use different conventions in the same conversation, one of them ends up surprised.

A useful discipline: whenever anyone gives you a percentage, ask what it is a percentage of. That single question resolves the entire ambiguity, and it takes less time than recalculating an order afterwards. If you want the margin view of the same sale in more depth, the profit margin calculator approaches it from the revenue side.

Four Caveats on Cost-Plus Pricing

Cost-plus pricing works, with four caveats worth holding in mind.

Landed cost is not invoice cost. Freight, duty, currency spread and any inspection or rework all belong in the cost figure. A 65% markup applied to an invoice price that excludes 8% of landed cost is really a 52.8% markup, and the difference is invisible on the pricing sheet.

Keystone is a starting point, not a law. Doubling cost — a 100% markup, 50% margin — is traditional in several retail sectors because it happened to cover overheads and shrinkage in a shop with a certain cost structure. Yours may be different in both directions.

Markup does not know about volume. A high markup on something that sells twice a month can generate less annual profit than a thin markup on something that sells daily. Stock turn matters as much as the percentage, and pricing decisions made on markup alone tend to ignore it.

Rounding to a psychological price changes the percentage. Pricing the example at $69.99 rather than $70.13 drops the markup to 64.68% and the margin to 39.28%. Trivial on one unit, and worth checking when the rounding is downward across a whole catalogue.

One practical note on where cost-plus stops working. If two competitors buy the same item at different prices, cost-plus gives them different selling prices for an identical product, which the customer has no reason to accept. In a market where prices are visible and comparable, cost-plus sets your floor and the market sets your ceiling — and if the floor sits above the ceiling, the answer is a sourcing problem rather than a pricing one.

For a full price build that starts from cost and works up through fees, shipping and target profit, the product pricing calculator goes further than markup alone, and the wholesale pricing calculator handles the two-tier case where the same item carries both a trade and a retail price.
