Calculate selling price from cost and markup, or find your markup percentage from cost and price.
Markup and margin are the two most commonly confused financial terms in retail and business pricing. Both measure the gap between cost and selling price, but they use different bases for the calculation — and confusing them leads to serious pricing errors.
Markup is calculated on cost: Markup% = (Price - Cost) / Cost × 100. A product that costs $40 and sells for $60 has a 50% markup ($20 profit on $40 cost). Margin is calculated on selling price: Margin% = (Price - Cost) / Price × 100. That same $40 cost / $60 price has a 33.3% margin ($20 profit on $60 revenue).
The relationship between them: Margin = Markup / (100 + Markup) × 100. And Markup = Margin / (100 - Margin) × 100. A 50% markup always equals a 33.3% margin. A 100% markup (doubling cost) equals a 50% margin. Knowing this conversion prevents the most common pricing error: setting a target margin of 40% but applying a 40% markup, which only delivers a 28.6% margin.
The right markup depends on three things: your operating cost structure, competitive market pricing, and your target profit margin. Start with your total operating expenses as a percentage of revenue — this tells you the minimum gross margin you need to break even. Add your desired net profit margin on top to get your target gross margin, then convert that margin target to a markup percentage.
Example: if operating expenses are 30% of revenue and you want a 10% net profit margin, you need 40% gross margin. A 40% gross margin corresponds to approximately a 67% markup (0.40 / 0.60 = 0.667). So you should price at cost × 1.667.
Industry conventions matter too. Retail clothing typically uses 100-300% markup (keystone and above). Electronics: 5-30%. Jewelry: 50-100%. Restaurant food: 300%+ on food cost. These are starting points — your actual markup should reflect your cost structure and competitive position.
Many businesses use different markup rates for different customer segments or order volumes. A manufacturer might have a 60% markup for retail customers, 40% for wholesale partners, and 20% for distributors — reflecting the different costs to serve each channel and competitive expectations.
When offering volume discounts, calculate the impact on your effective markup and margin carefully. A 10% volume discount to a customer buying 10× the normal quantity may be excellent economics (lower per-unit cost, no sales effort, better cash flow) or terrible economics (discounting past your break-even) depending on your cost structure.
