A markup calculator sets the selling price of a product or service from its cost and the percentage you want to add on top. Retailers, manufacturers, tradespeople, and freelancers use it to price consistently β covering what an item costs them and building in the profit layer that keeps the business running β instead of guessing a price or copying a competitor's.
Quick Answer
Selling Price = Cost Γ (1 + Markup %). An item that costs $40, marked up by 75%, sells for $40 Γ 1.75 = $70. The reverse formula finds the markup in an existing price: Markup % = (Price β Cost) Γ· Cost Γ 100, so an $80 cost sold at $120 carries a markup of (120 β 80) Γ· 80 = 50%.
Markup Is Not Margin β and the Difference Costs Money
Markup expresses profit as a percentage of cost; gross margin expresses the same profit as a percentage of the selling price. Because the denominators differ, the two numbers are never equal (except at zero). On the $40-to-$70 example, the profit is $30 either way, but the markup is 30 Γ· 40 = 75% while the margin is 30 Γ· 70 = 42.9%. This gap causes real losses: a shopkeeper who wants a 50% margin but applies a 50% markup to a $40 cost prices at $60, where the margin is only 20 Γ· 60 = 33.3% β a third less profit share than intended, on every sale, indefinitely.
One landmark is worth memorizing: doubling the cost (a 100% markup, sometimes called "keystone" pricing in retail) produces a 50% margin, not a 100% one. A margin above 100% is impossible, since profit cannot exceed the price; a markup can rise without limit. When a supplier, accountant, or marketplace dashboard quotes you a percentage, always check which of the two it is before acting on it.
There is a one-line conversion if a target margin is what you actually have in mind: margin = markup Γ· (1 + markup), using decimals. A 50% markup is a margin of 0.50 Γ· 1.50 = 33.3%; a 100% markup is 1.00 Γ· 2.00 = 50%; and to land a true 50% margin you must solve in the other direction and apply a 100% markup β the two scales only meet at zero. Keep this conversion near the till and most markup-versus-margin confusion disappears.
Markup also compounds along a supply chain, which surprises people seeing a shelf price for the first time. A maker with a $20 unit cost applies a 50% markup and sells to a wholesaler at $30. The wholesaler applies 40% and sells to a retailer at $42. The retailer applies 60% and tickets the item at $67.20. No single step looks extreme, yet the final price is 3.36 times the original cost, and the maker's $10 of profit is a small slice of the $47.20 added along the way. This is not evidence of anyone cheating; each layer is funding transport, storage, premises, and unsold stock. But it does explain why selling direct can undercut a shelf price so dramatically, and why each business in the chain watches its own percentage rather than the total.
How to Use the Markup Calculator
- Work out the full unit cost of the item β purchase or production cost plus its share of packaging, shipping-in, and any per-unit fees.
- Enter that cost into the calculator.
- Enter the markup percentage you want to apply.
- Read the selling price and the profit per unit it implies.
- If you already have a price, use the reverse direction: enter cost and price to find the markup you are actually charging.
- Sense-check the result against the market β a mathematically sound price still has to be one customers will pay.
Worked Example: Pricing a Handmade Candle
A candle maker totals the wax, fragrance, jar, wick, label, and packaging for one candle at $12.50. She prices with a 100% markup: $12.50 Γ 2.00 = $25.00 retail, of which $12.50 is profit β a 50% margin, leaving room for the wholesale discount cafΓ©s will ask for when they buy in cases. Working the other way, a bike shop buys a helmet for $90 and tickets it at $120: markup = (120 β 90) Γ· 90 = 33.3%, margin = 30 Γ· 120 = 25%. More quick pairs:
- Cost $25 with a 60% markup β price $40
- Cost $8 with a 150% markup β price $20
- Cost $200 with a 25% markup β price $250
- Price $45 on a $30 cost β markup of 50%, margin of 33.3%
Pricing Mistakes This Calculator Cannot Fix for You
The formula is only as honest as the cost you feed it. The most damaging error is pricing from the invoice cost alone while forgetting freight, breakages, card-processing fees, marketplace commissions, and returns β the true unit cost creeps up and the "profit" evaporates. Second, applying markup to the selling price instead of the cost when working backwards, which understates your real percentage. Third, one blanket markup for everything: slow-moving or space-hungry stock usually needs a higher margin contribution than fast sellers, which is why experienced retailers set markup by category. Fourth, forgetting that discounts come out of the marked-up price β a product priced for a 75% markup and then sold at "30% off" may be selling near cost, so plan promotional room into the original markup.
Prices produced here are planning figures based on the costs and percentages you enter. They are not financial advice; final pricing should also reflect your overheads, tax position, competition, and what your market will bear.
From Shelf Price to Sale Price
Once a marked-up price exists, two neighbours in the toolbox take over: the Margin Calculator converts your percentages into the margin language accountants and marketplaces speak, and the Discount Calculator shows what a promotional reduction does to the final ticket and to your profit per unit. Both are part of the Business Calculators set, built for exactly this chain of pricing decisions.
