48 questions, answered plainly
Published by Cydney Mar Last updated: November 2026
Here are direct answers to the questions founders ask most about product costing, margins, markup and pricing for retail, TV and DTC.
The Cost Sheet FAQ, published by Cydney Mar, groups 48 questions into 8 topics. Each answer starts with the direct answer, then the supporting facts. To run your own numbers, use the product costing calculator.
It answers how to cost a product, how to calculate and judge margins, how markup differs from margin, what changes by channel, how the free tools work, and what a product development consultant does. Jump to a topic below.
A product costing calculator adds up everything it takes to make and land one unit of a product, then shows what you must charge to hit a target margin. The free calculator on The Cost Sheet totals materials, labor, packaging, freight and duties, and other per unit costs, then converts a target gross margin into a selling price.
Product cost is calculated by adding every cost that goes into one finished, delivered unit. For a consumer product that usually means materials and components, labor or factory charges, packaging and labels, inbound freight, duties, and allowances for testing, samples and defects. Divide any batch level cost by the number of units in the batch so every line is per unit.
Landed cost is the full cost of a unit once it arrives at your warehouse, ready to sell. It is the factory price plus inbound freight, insurance, duties and tariffs, brokerage and any handling fees. Pricing from the factory price alone is a common mistake, because freight and duties can change your margin noticeably once the goods actually arrive.
A variable costing unit product cost calculator counts only the costs that rise with each unit made: direct materials, direct labor and variable overhead. Fixed overhead such as rent is left out of the unit cost and treated as a period expense. Absorption costing, by contrast, spreads fixed manufacturing overhead across units. The Cost Sheet calculator works on a variable, per unit basis.
Yes. The product costing calculator on The Cost Sheet is free, needs no account and runs in your browser. Enter your per unit costs and a target margin to see a selling price, gross profit per unit and markup. Results are estimates for planning, not financial advice, so check them against real supplier quotes.
The Cost Sheet offers a free product cost sheet template as a CSV file that opens in Excel, Google Sheets or Numbers. It lists the common cost lines for a consumer product and includes formulas that total your landed cost and turn a target margin into a selling price. Download it from the cost sheet template page.
A price cost margin is the share of the selling price left after the cost of the unit is covered, written as price minus cost, divided by price. If a product sells for $100 and costs $40, the price cost margin is 60%. In everyday product pricing it is the same calculation as gross margin per unit.
To calculate margin on a product, subtract the unit cost from the selling price, divide the result by the selling price, and multiply by 100. A product that costs $40 and sells for $100 has a $60 gross profit and a 60% margin. Margin is always a share of the price, never a share of the cost.
If $100 is the selling price, a 30% margin means $30 of gross profit and a unit cost of $70. If $100 is your cost and you want a 30% margin, divide by 0.70: the selling price is about $142.86 and the profit about $42.86. Always confirm whether the $100 is the price or the cost.
To calculate a 30% profit margin, divide your unit cost by 0.70, which is 1 minus 0.30. A product that costs $35 needs a $50 price to earn a 30% margin, because $15 of profit is 30% of $50. Adding 30% to the cost instead gives a price of $45.50 and only a 23.1% margin.
A 20% gross margin means 20 cents of every sales dollar is left after the cost of the product, not 20% net profit. Marketing, fulfillment, salaries, rent and other expenses still come out of that 20 cents. Net profit is what remains after all of those costs, so it is usually lower than gross margin.
To calculate profit margins of a product on Amazon, subtract your landed unit cost plus the marketplace referral fee, fulfillment fee and advertising cost per unit from the selling price, then divide by the selling price. Fee rates change and vary by category and size, so confirm the current figures in your seller account before setting a price.
Add profit and cost to get revenue, then divide profit by revenue. Calculator Soup's margin calculator uses the example of a $100 cost and $25 profit, giving $125 in revenue. Working that example through: $25 divided by $125 is a 20% margin, while the markup on cost is 25%.
Subtract cost of goods sold from net sales, divide by net sales, and multiply by 100. Zendesk's profit margin guide uses net sales of $10,000 and COGS of $6,000, which gives a 40% gross profit margin. The same method works for one SKU or an entire collection over a season.
For physical products, a gross margin of 30% to 60% is a common published range, according to Product Marketing Alliance's 2026 pricing guide, which puts digital products at 80% to 95%. Where your product should land depends on channel: selling through a retailer or TV partner typically leaves you less of the final price than selling direct.
A good gross profit (GP) ratio for physical consumer products often falls between 30% and 60%, the range Product Marketing Alliance publishes for physical products. Software is different: Founderpath lists SaaS and software at 70% to 90% margin. Compare your ratio with products sold through the same channel, not with businesses that have very different costs.
It depends on which margin. As a gross margin on a physical product, 20% is below the 30% to 60% range Product Marketing Alliance publishes, which leaves little room for channel costs. As a contribution margin after acquisition costs, Wayflyer's 2026 guide calls 20% the minimum healthy level for eCommerce, with sustainable brands targeting 20% to 25% or more.
No. A 40% gross margin sits inside the 30% to 60% range Product Marketing Alliance publishes for physical products. Sage's margin guide explains a 40% margin as 40% of every dollar earned remaining as profit after direct costs have been paid. Whether it is enough depends on your channel costs, marketing spend and overhead.
A 50% gross margin is not too much for a physical consumer product; it sits in the middle of the 30% to 60% range Product Marketing Alliance publishes. Brands that sell through retailers or TV partners often need room in the margin for the partner share, promotions and returns, so a healthy gross margin protects the business.
A 55% gross profit margin is near the top of the 30% to 60% range Product Marketing Alliance publishes for physical products, which is generally a strong position. It leaves room for channel costs, marketing and overhead. Check it against your full cost list, because a high gross margin can still hide missing freight or duty lines.
A 70% gross margin is high for a physical product, above the 30% to 60% range Product Marketing Alliance publishes, and it sits at the low end of the 70% to 90% range Founderpath lists for SaaS and software. For a consumer product company, 70% usually signals strong pricing power or a lean cost structure, provided every cost line is counted.
No. A 30% markup adds 30% of the cost to the cost, while a 30% margin is 30% of the selling price. A $70 cost with a 30% markup sells for $91 and earns a 23.1% margin. To earn a true 30% margin on a $70 cost, you need a $100 price.
Yes. A 100% markup doubles the cost, so a $20 product sells for $40. The $20 profit is 100% of the cost but 50% of the selling price. That is why a 50% margin and a 100% markup describe exactly the same price, just measured against different bases.
Yes, a 50% margin and a 100% markup produce the same price. If a unit costs $25 and sells for $50, the $25 profit is half the price, a 50% margin, and equal to the cost, a 100% markup. The conversion is margin equals markup divided by 1 plus markup.
A 200% markup equals a 66.7% margin. With a 200% markup, a $10 cost sells for $30, leaving $20 of profit, and $20 divided by $30 is 66.7%. Online Labels notes that as a business grows and demand increases, it may be able to raise markup to 80%, 100%, or even 200%.
Online Labels' profit margin calculator says markup varies by industry, but many businesses start in the 30% to 50% range to cover costs while staying competitive. Note that a 50% markup is only a 33.3% margin. Convert any markup to margin before comparing it with margin benchmarks or channel requirements.
Price with margin when you sell through retailers, TV partners or to investors who think in margin, and use markup only as a quick shortcut. Margin keeps your planning tied to the selling price, which is where discounts, partner shares and returns are calculated. The Cost Sheet tools show both, so you can speak to buyers in either language.
The Cost Sheet is for founders building consumer products for retail, TV shopping and direct to consumer channels who want to price with real numbers. It is published by Cydney Mar, a product development strategist with 45+ years of experience and $300M+ in global product sales across retail, TV and DTC.
Selling through a retailer usually means the retailer buys at a wholesale price and keeps its own margin on the shelf price, so your margin is earned on the wholesale price, not the retail price. Build your cost sheet first, set your wholesale price from your target margin, then check that the resulting shelf price is believable for the category.
Before pricing for TV shopping, confirm the partner terms in writing: how they buy, who pays freight, how returns are handled and any required quantities. Then cost your unit with those terms included. Cydney Mar sold her own collections on QVC for 15+ years across 8 countries, with more than 800 hours of live television.
Direct to consumer brands most often forget per order costs: pick and pack, shipping to the customer, payment processing, shipping packaging, returns and customer acquisition. These sit below gross margin, which is why Wayflyer's 2026 guide measures eCommerce health by contribution margin after acquisition costs, with 20% as the minimum.
Contribution margin is the selling price minus all variable costs to produce, ship and acquire the customer for that sale. In Wayflyer's example, a product that sells for $100 with $65 of total variable costs has a $35 contribution margin, which is 35% of the price. It shows what each sale contributes toward fixed costs and profit.
Cost plus margin pricing starts with the full unit cost and divides it by 1 minus your target margin to get the price. In Product Marketing Alliance's example, a $40 total cost at a 60% target margin gives $40 divided by 0.4, a $100 selling price. It is simple and protects margin, but test the price against the market too.
A product cost sheet should include every per unit cost: main materials, trims and components, labor or assembly, packaging, labels and tags, inbound freight, duties and tariffs, testing, samples spread per unit, a waste allowance, and fulfillment if you sell direct. The free template on The Cost Sheet lists these lines with formulas for landed cost and price.
A margin checklist confirms you have counted every cost and every party that shares in the price before you commit. The Cost Sheet checklist covers cost completeness, channel terms for retail, TV and DTC, discount and return allowances, and a final check that your price still clears your target margin.
Calculate costs and margins before you commit to sampling or a production order, and again when real supplier quotes arrive. Cydney Mar's Concept-to-Reality Pathway places Cost and Margins after prototypes and suppliers but before production readiness, so pricing is built on real quotes instead of guesses.
The arithmetic is exact, but the result is only as accurate as the costs you enter. It is an estimate for planning, not a financial, legal or tax decision. Use real supplier quotes, include freight and duties, and confirm final numbers with your accountant or a product development professional before committing to a price.
The calculator works in any currency as long as every figure you enter uses the same one. Results are shown with a dollar sign for readability. If a supplier quotes in a different currency, convert each quote at a realistic rate first, and consider adding a small allowance for exchange rate movement.
A consumer product development consultant guides founders from idea to a product ready to sell. Cydney Mar's Concept-to-Reality Pathway covers six stages: product clarity, the right prototypes, the right suppliers, costs and margins, production readiness, and launch and scale through retail, DTC or TV.
A garment tech pack is the technical document a factory uses to make your product: specifications, measurements, materials and construction details. Cydney Mar describes a clear, professional tech pack as the difference between a sample that is right the first time and months of expensive back and forth with a factory.
A product development strategy is the order of decisions that takes an idea to a product people buy: who it is for, what it is, how it is sampled, who makes it, what it costs and how it reaches market. Cydney Mar's approach centers on doing the right steps in the right order, which reduces costly guesswork.
A product launch checklist should confirm a defined product and buyer, approved samples, vetted suppliers, a costed and priced unit, finalized specifications for consistent manufacturing, and a channel plan for retail, DTC or TV. Those items mirror the six stages of Cydney Mar's Concept-to-Reality Pathway.
Product development consulting firms usually work through strategy sessions, defined programs or ongoing advisory. Cydney Mar runs Cydney Mar Consulting, an Indigenous-owned product development firm based in Montreal, and starts with a strategy call to talk through your idea. Prices are not published, so contact her directly for current options.
Yes. Finding the right suppliers is one of the six stages of Cydney Mar's Concept-to-Reality Pathway, which looks for suppliers vetted for quality, communication and reliability. Her work also covers sampling, sourcing, costing and production readiness, so suppliers are chosen with real costs and margins in mind.
Cydney Mar has 45+ years in fashion and product and over $300 million in retail, TV and DTC sales. She sold her own collections on QVC for 15+ years in 8 countries, designed Cirque du Soleil's first Boutique Collection and led design for Edwin Jeans in North America.
A good gross margin can still lose money when costs below the gross line are large: marketing, fulfillment, returns, discounts and overhead. It also happens when the cost sheet missed lines such as freight, duties or defects. Rebuild the unit cost with every line, then check contribution margin per order, not just gross margin.
Minimum order quantities affect unit cost because many charges are fixed per order, such as setup, tooling, samples and freight minimums. Spread over fewer units, each unit costs more. Ask suppliers for prices at two or three quantities and run each through the calculator so you can see where your margin becomes workable.
If the calculated price is too high, change the cost, not the margin math. Options include simplifying materials or construction, changing packaging, ordering larger quantities, choosing a different channel, or repositioning the product for a buyer who values it more. A product development strategist can help find the change that protects both quality and margin.
Cost and Margins is one stage of Cydney Mar's Concept-to-Reality Pathway, which takes founders from product clarity to prototypes, suppliers, production readiness and launch in retail, TV or DTC.
