Markup Calculator

Every markup percentage has a corresponding margin percentage, and they convert cleanly with a small formula pair: margin equals markup divided by (1 plus markup), and markup equals margin divided by (1 minus margin), both as decimals. A 25% markup converts to a 20% margin (0.25 ÷ 1.25 = 0.20); a 50% markup converts to a 33.33% margin (0.50 ÷ 1.50 = 0.3333). Margin is always the smaller figure on a profitable sale, and the gap between the two grows as the percentage climbs — at very high markups, like the 150%+ common in specialty apparel, the margin sits dramatically lower than the markup number alone would suggest.

A concrete illustration that shows up in pricing guides from Sage and elsewhere: a $5 item marked up 50% sells for $7.50, but the same $5 item priced to hit a 50% margin has to sell for $10, because a 50% margin means half of the selling price is profit, which only works out if the selling price is double the cost. Same cost, same intended "50%," two very different prices — the source of most real-world markup versus margin confusion isn't the arithmetic, it's assuming the word "50%" means the same thing both times.

The practical risk runs one direction more often than the other: a business that wants a specific margin, because that's the number tied to covering overhead and hitting a profit target, but prices using a markup formula instead, will consistently under-price. A 40% markup on a $100 cost item sells for $140 and nets a 28.57% margin, not the 40% margin that might have been the actual goal — a gap of over 11 percentage points that compounds across every unit sold.

Markup varies enormously by business model, and the ranges below are general orientation, not a target to copy without checking your own overhead and competition. Grocery and other high-volume, low-margin retail commonly runs markups in roughly the 10% to 40% range, since thin margins are offset by sales volume and fast inventory turnover.

Restaurants sit at the other end for food specifically: the widely cited industry benchmark targets a food cost of 28% to 35% of the menu price, which works out to a markup on that food cost of roughly 185% to 260% — a number that looks aggressive until you remember it has to cover labor, rent, and everything else a plated meal involves beyond the raw ingredients. Specialty retail and apparel frequently sit well over 100% markup, sometimes 150% to 250%, to absorb seasonal discounting, returns, and the cost of carrying inventory that doesn't always sell at full price.

What actually sets a sustainable markup for a specific business is overhead, competition, and how fast inventory turns, not an industry average pulled from a blog post. A business with low fixed costs and fast turnover can often profit at a markup well below its category's typical range; one with high overhead or slow-moving stock may need to run above it just to break even. Treat any industry figure, including the ranges above, as a starting point for a conversation with your own numbers, not a number to key in directly.

Markup is the more intuitive number for setting a single price — it's a direct percentage added to what you already know, the cost. Margin is the more useful number for the bigger question of whether the business as a whole is sustainable, because margin percentage is what actually funds everything that isn't the direct cost of goods: rent, payroll, marketing, and profit. A retailer running a 20% margin keeps 20 cents of every sales dollar before those overhead costs are paid; the other 80 cents already went to the supplier. That framing is why margin, not markup, is the number that shows up in break-even and profitability analysis: break-even revenue is fixed costs divided by margin percentage, so a lower margin means every fixed dollar of overhead requires proportionally more total sales to cover.

This is also why pricing purely off a target markup can quietly erode profitability even when every individual sale looks fine on paper. If overhead grows relative to sales volume, sales that were profitable at last year's cost of goods and last year's markup can produce a lower margin than the business actually needs to cover its current fixed costs — a gap that a markup-only view of pricing won't surface, because markup only ever looks at cost, never at what share of revenue overhead is consuming.

"Cost" isn't always just the number on a supplier's invoice. For a reseller, the cost of goods sold is the wholesale or unit price of the item, but a fuller landed cost also folds in inbound shipping, customs and duties, and packaging — expenses that hit every unit before it's ever offered for sale. Running a markup against only the invoice price systematically overstates real profitability once those add-on costs are counted, because the same dollar of apparent profit has to stretch further than the calculation assumed.

Online sellers hit a similar blind spot from the other direction: payment-processing fees and marketplace referral commissions come out of the selling price after the sale closes, not out of the cost entered beforehand. Whether to fold these into cost, which raises the base a markup is measured against, or track them as a separate deduction from profit afterward is a judgment call — but leaving them out entirely, on either side, is how a markup can look healthy on paper while the bank balance tells a different story.

One retail convention worth knowing by name is keystone pricing: doubling the wholesale cost, which is exactly a 100% markup and a 50% margin. It became a default in independent retail because it's fast to calculate by hand and leaves room to absorb markdowns, theft, and slow-moving inventory — not because 100% is inherently the right markup for everything. Categories with thin competitive margins, like electronics, often markup well below keystone; fashion and jewelry frequently run above it. It's a starting heuristic this calculator doesn't assume, not a rule it enforces.
