Cost-plus pricing is the simplest and most widely used pricing method in retail, manufacturing, and wholesale: you take what a product costs you, add a fixed percentage (the markup), and that becomes the price you charge the customer. This calculator walks through that math in one step and, just as importantly, shows you what your markup actually translates into as a profit margin — because markup and margin are not the same number, and confusing them is one of the most common mistakes small business owners make.
Type a product cost, a desired markup, and (optionally) the quantity you plan to sell below, and the result card updates instantly with the selling price per unit, gross profit per unit, profit margin, return on cost, the price-to-cost multiplier, and the total batch revenue, batch cost, and batch gross profit for your planned volume.
How to Use
- Enter the Product Cost (COGS per Unit). This is the fully-loaded cost to make or buy one unit — materials, factory labor, packaging, freight, and any other direct cost. Do not include your salary or office rent here unless you can fairly allocate them to each unit.
- Set the Desired Markup as a percentage. A 50% markup means you want to add half the cost on top of the cost itself.
- Enter the Quantity Sold you expect to move at this price. The default of 100 units is only a starting point; set it to your actual forecast, a minimum order, or a monthly run rate. Leave it at 100 if you only care about the per-unit math.
- Read the Selling Price on the result card — that is the price you charge the customer.
- Check the Profit Margin. It will always be lower than your markup. For a 50% markup, the margin is about 33.3%, not 50%. This gap is the single most useful number on the page.
- Use the Return on Cost (ROI) to compare pricing decisions across products. It tells you how many dollars of gross profit you earn for every dollar of cost you put in.
- The Price as Multiple of Cost is the raw multiplier — a 50% markup is a 1.5x multiplier, a 100% markup is 2x, and so on.
- Scroll down to the batch totals. Total Batch Revenue is selling price × quantity, Total Batch Cost is product cost × quantity, and Total Batch Gross Profit is the money left after paying for the units you sold — the number that actually pays your rent and payroll.
If your actual landed cost is different from what you thought, adjust it in the first box and every output recalculates.
The Cost Plus Pricing Formula
Cost-plus pricing is built on one core equation:
Selling Price = Product Cost × (1 + Markup % ÷ 100)
From there, three supporting numbers fall out:
- Gross Profit per Unit = Selling Price − Product Cost
- Profit Margin = Gross Profit ÷ Selling Price × 100
- Return on Cost (ROI) = Gross Profit ÷ Product Cost × 100
Once you plug in a quantity, three batch totals fall out on top:
- Total Batch Revenue = Selling Price × Quantity
- Total Batch Cost = Product Cost × Quantity
- Total Batch Gross Profit = Gross Profit per Unit × Quantity
Worked example: a product costs you $40 and you want a 50% markup. Selling price = $40 × 1.50 = $60. Gross profit is $20. Profit margin is $20 ÷ $60 = 33.3%. Return on cost is $20 ÷ $40 = 50%. If you expect to sell 100 units, batch revenue is $6,000, batch cost is $4,000, and batch gross profit is $2,000. Notice the markup (50%) and the margin (33.3%) are different — the markup is a percentage of cost, while the margin is a percentage of the selling price. As the markup grows, the margin grows more slowly, and the two can never meet.
The relationship between markup and margin is fixed: a 25% markup is a 20% margin, a 50% markup is a 33.3% margin, a 100% markup is a 50% margin, and a 200% markup is a 66.7% margin. Sales teams often quote markup while finance teams care about margin, so keeping both numbers in front of you prevents embarrassing disagreements.
Markup vs Margin — Why the Difference Matters
Imagine two products that both cost you $50. Product A uses a 50% markup and sells for $75, earning $25 of profit on a $75 sale (33.3% margin). Product B uses a 100% markup and sells for $100, earning $50 of profit on a $100 sale (50% margin). Product A earns more relative to every dollar of revenue it brings in; Product B earns more in absolute dollars but requires a higher price point and may lose volume.
The margin also matters because it is what funds all the other bills — rent, salaries, advertising, shipping, and taxes — that the product cost deliberately left out. If your margin is 20% but your operating expenses eat 25% of revenue, every sale loses money. Cost-plus pricing on its own does not guarantee profit; it only guarantees a predictable relationship between cost and price. You still have to sell enough units at that price to cover overhead.
Examples
Example 1 — The textbook case. A candle maker spends $4 in wax, wicks, fragrance, and a jar to produce one candle, and wants a 50% markup. Selling price = $4 × 1.50 = $6.00. Gross profit per candle is $2.00, profit margin is 33.3%, and return on cost is 50%. Enter 500 for the quantity sold, and the batch totals appear: $3,000 of batch revenue, $2,000 of batch cost, and $1,000 of gross profit before fixed costs — the number that has to cover rent, the website, and the maker's time.
Example 2 — A zero-markup break-even price. A reseller is forced by a competitor to match a price exactly equal to their cost of goods. Enter a product cost of $40 and a desired markup of 0%. The calculator returns a selling price of $40.00, $0 gross profit, a 0% margin, and 0% ROI. This confirms that the sale covers the wholesale cost but contributes nothing to operating expenses or profit — useful as a worst-case floor, not a strategy.
Example 3 — High-value wholesale order. A manufacturer quotes a custom part that costs $1,500,000 to produce, and applies a 40% markup. Selling price = $1,500,000 × 1.40 = $2,100,000. Gross profit is $600,000, the profit margin is 28.6%, and return on cost is 40%. Even at this scale the math is identical to the $40 candle — only the decimal places move.
FAQ
What is cost plus pricing?
Cost-plus pricing is a pricing method where you calculate the cost of producing one unit and then add a fixed percentage (the markup) to arrive at the selling price. It is the default method for manufacturers, government contracts, and many wholesale businesses because it is transparent, easy to defend, and guarantees a known dollar profit on every sale.
How do I calculate selling price from cost and markup?
Multiply the product cost by one plus the markup percentage divided by 100. For a $40 product with a 50% markup: $40 × (1 + 0.50) = $60. This calculator performs that math instantly and also shows the resulting margin and ROI so you can see how the markup translates into profit on each dollar of revenue.
What is the difference between markup and margin?
Markup is profit divided by cost; margin is profit divided by selling price. A 50% markup on a $40 item produces a $60 price and $20 profit, which is a 33.3% margin — never 50%. Markup is always a larger number than the margin it produces, and the gap widens as the markup grows. Confusing the two is a leading cause of underpricing.
What markup percentage should I use?
There is no universal number, but common starting points are 50% for retail, 20–40% for wholesale and manufacturing, and 100%+ for branded or luxury goods. The right markup depends on your operating expenses, competition, customer willingness to pay, and how often customers repurchase. Use this calculator to test several markups side by side, then compare the resulting margin against your industry's average.
Does cost plus pricing include overhead?
By default, no. The product cost should include direct costs (materials, labor, packaging, freight) but not indirect overhead like rent, marketing, or the owner's salary. If you want overhead baked in, either raise the markup until the margin covers operating expenses, or add a fixed overhead allocation per unit into the product cost field before calculating.
Can cost plus pricing be used for services?
Yes. Treat the "product cost" as the fully-loaded labor cost to deliver the service — wages, payroll taxes, benefits, and any materials — and apply a markup the same way. A freelance developer whose fully-loaded hourly cost is $50 and who wants a 100% markup should bill $100 per hour, producing a 50% margin.
What are the disadvantages of cost plus pricing?
It ignores competitors, customer willingness to pay, and brand value, so you can easily price too high (and lose sales) or too low (and leave money on the table). It also gives you no incentive to reduce costs, because a fixed percentage markup means you earn more by spending more. Use cost-plus as a baseline, then adjust up or down based on market research.
Why does the quantity input matter if I only care about price?
The per-unit selling price, margin, and ROI do not depend on quantity at all — they are set by cost and markup alone. The quantity field is what turns those per-unit numbers into the batch totals (revenue, total cost, total gross profit) that you actually need to decide whether a product is worth carrying. A 50% margin looks great until you realize that at 50 units a month the batch gross profit is $1,000, which will not cover your rent. Use quantity to stress-test whether the price and volume you have chosen actually produce the annual profit your business needs.
