40 Percent Markup Calculator

40% markup: the quick math and the catch

A 40% markup means selling at cost × 1.4: $100 becomes $140, $35.50 becomes $49.70. Simple. The catch is what 40% markup isn't: a 40% margin. That $40 profit on a $140 price is a 28.6% margin. Businesses that promise investors "40% margins" while pricing with "40% markup" are 11 points short and usually don't discover it until year-end.

Markup ↔ margin conversion

Margin = markup ÷ (100 + markup) × 100. So 40% markup → 28.6% margin; 50% → 33.3%; 100% → 50%. Going the other way, markup = margin ÷ (100 − margin) × 100: a 40% margin needs a 66.7% markup. The table beside the calculator shows both numbers for every common level so the conversion is never a surprise.

Where 40% markup fits

It's a workhorse rate: common in food retail, auto parts, mid-range services, and contracting (where it lands inside the typical 20–50% band). It's too thin for handmade goods and boutique retail (which need keystone, 100%+) and thick for high-volume commodity distribution. The question isn't whether 40% is "right": it's whether the resulting margin covers your overhead with profit left; check that in the break-even calculator.

Markup and margin are different numbers

Stacking costs before applying markup

A 40% markup only protects margin if the cost base is complete. Labor burden - payroll taxes, workers' comp, benefits - typically adds 25–35% on top of raw wages. A worker earning $28/hr costs $35–$38/hr fully burdened. Marking up the raw wage instead of the burdened rate causes a silent loss of $8–$10 per labor hour. Material cost must include freight, shrinkage allowance (typically 2–5% for construction trades), and any import duties. Missing one line item from the cost base invalidates the markup calculation entirely. Use a job costing calculator to assemble a defensible total cost before inputting the figure here.

Volume tiers and when 40% breaks down

Wholesale buyers expect price breaks. A standard retail markup of 40% on a $50 unit cost yields a $70 sell price. At 500-unit order quantities, channel partners typically demand a 20–25% discount off that retail price, compressing realized revenue to $52.50–$56 per unit - leaving a margin of only 5–11% rather than the 28.57% implied by a clean 40% markup. At volume, the markup percentage must increase or the cost base must fall to preserve margin. A wholesale price calculator handles tiered pricing logic this tool does not.

What this calculator does not cover

This tool computes a single-product sell price from a single cost input. It does not account for: blended markup across product mixes, where high- and low-margin SKUs average out; returns and chargebacks, which erode net revenue below the marked-up price; payment processing fees of 1.5–3.5% that reduce effective margin post-sale; or minimum advertised price (MAP) policies that may cap the sell price below the 40% markup output. Retail MAP violations can trigger supplier termination without legal recourse in most US states. If the marked-up price exceeds the MAP threshold, the pricing strategy - not just the markup percentage - must change. Run the break-even calculator alongside this tool to confirm unit volume requirements at the constrained price point.

Benchmarks by sector

A 40% markup is above average in grocery (12–25%) and consumer electronics (10–30%), at the low end for apparel (40–100%), and below standard for specialty retail and contractor services where 50–100% markups are common. HVAC contractors typically target 50–65% markup on materials. Restaurants mark up food cost by 200–300% (67–75% margin). Knowing the sector benchmark reveals whether a 40% markup is defensible to buyers or is leaving margin on the table.
