Turn a cost and markup % into a selling price, work the markup back out from a price, or recover the cost — with profit, margin, and the markup-to-margin chart that trips everyone up.
Using cost + markup %
What you paid for the item
Percentage added on top of cost
Markup is profit over cost; margin is the same profit over price. Both come from one sale.
Markup is the amount you add on top of what an item cost you, written as a percentage of that cost. It answers a seller's core question — “what do I charge?” — and it is the single most common way small businesses set prices. Two formulas do all the work: one builds a price from a markup, the other reads the markup out of a price.
Three steps take you from a cost and a target markup to a selling price you can put on the shelf.
Pick how much profit you want as a share of cost. A 50% markup means half the cost again on top.
Add 1 to the markup written as a decimal. This is the factor you multiply the cost by.
The product is your selling price — cost plus profit, in one step.
Profit is price minus cost; margin is that profit over the price, not the cost.
The same relationship, solved three ways — for the price, the markup, or the original cost.
You know your cost and the markup you want to apply.
These two get mixed up constantly, and the mix-up quietly destroys margins. They describe the same profit — but divide it by different numbers.
Convert between them whenever you need to: margin = markup ÷ (100 + markup) × 100 and markup = margin ÷ (100 − margin) × 100. The chart below does it for every common markup at once.
Every common markup, its equivalent margin, the cost multiplier, and the selling price it produces — set your own base cost and read it straight off.

Note how a 100% markup is only a 50% margin — markup always reads higher than the margin it produces, because it divides by the smaller number (cost, not price).
There is no universal “right” markup — it swings wildly by trade. Here is where common businesses land. Use it as a sanity check, not a rule.
| Industry | Typical markup | Why |
|---|---|---|
| Grocery / supermarket | 15%–25% | High volume, thin margins |
| Restaurants (food) | 200%–300% | Covers labor, rent, waste |
| Restaurants (alcohol) | 200%–600% | The real profit center |
| Clothing / apparel | 100%–350% | "Keystone" doubling is common |
| Jewelry | 100%–500% | Brand and rarity premium |
| Furniture | 200%–400% | Low turnover, high ticket |
| Electronics | 5%–25% | Competitive, razor-thin |
| Pharmacy (generic) | 200%–800% | Insurance-driven pricing |
| Auto (new cars) | 5%–10% | Margin is in service & finance |
| Eyewear / glasses | 300%–1000% | Famously high markup |
One percentage drives pricing, profitability, and the survival of every product business.
A handful of facts keep markup straight and stop the margin from leaking away.
Before barcodes and spreadsheets, retailers needed a markup they could apply in their head to an entire store. Doubling the wholesale cost — “keystone” pricing, named for the central stone that locks an arch — was simple, fast, and forgiving enough to cover overhead in most trades. It is a 100% markup and a 50% margin, and it remains the default mental model for small retail today, even as competitive categories like electronics have been squeezed far below it.

Gross is the total before deductions; net is what is left after deductions are subtracted. This guide explains gross vs net for pay, income, and profit with worked dollar examples and a quick comparison table.

Writing a check takes six fields: the date, the payee, the amount in numbers, the amount in words, an optional memo, and your signature. This guide walks every field with one worked example and shows exactly how to write the cents.

The compound interest formula is A = P(1 + r/n)ⁿᵗ, where P is the starting principal, r is the annual rate as a decimal, n is the number of times interest compounds per year, t is the number of years, and A is the final amount. This guide defines each variable, works a full example, and shows how compounding frequency changes the result.
