To calculate the selling price per unit, start with your total cost per unit and add your desired profit. The simplest formula is: Selling Price = Cost Per Unit + Desired Profit Per Unit. But the specific method you use depends on whether you’re working from a markup amount, a target margin percentage, or a break-even threshold. Each approach gives you a different way to land on the right number.
Know Your Cost Per Unit First
Before you can set a selling price, you need an accurate picture of what each unit costs to produce or acquire. Your cost per unit includes every direct expense tied to making or buying the product: raw materials, manufacturing labor, and production overhead like factory utilities or equipment maintenance. If you buy finished goods to resell, your cost per unit is simply your wholesale purchase price plus any freight or handling to get it into your inventory.
Costs that aren’t directly tied to production, like marketing, office rent, and administrative salaries, are not part of your per-unit cost in most pricing formulas. Those expenses matter for profitability (and they show up in break-even analysis), but they sit outside the direct cost calculation. Keeping them separate gives you a cleaner view of your true production cost and a more accurate gross margin.
To get a per-unit figure, divide your total direct costs for a period by the number of units produced in that same period. If you spent $50,000 on materials, labor, and manufacturing overhead last month and produced 10,000 units, your cost per unit is $5.00.
The Markup Method
Markup pricing adds a fixed dollar amount or percentage on top of your cost. The formula is straightforward:
Selling Price = Cost Per Unit + Markup Amount
If your cost per unit is $5.00 and you want a $3.00 markup, you sell at $8.00. When expressed as a percentage, that $3.00 markup on a $5.00 cost is a 60% markup (3 ÷ 5 = 0.60).
Markup is popular because it’s easy to apply across a product line. You pick a percentage, multiply your cost by that percentage, and add it on. A product that costs $12.00 with a 50% markup becomes $18.00 ($12.00 × 0.50 = $6.00, then $12.00 + $6.00 = $18.00).
One thing to keep straight: markup and margin are not the same number. A 50% markup does not give you a 50% margin. In the example above, your $6.00 profit on an $18.00 selling price is a 33.3% gross margin. Markup is calculated on cost; margin is calculated on the selling price. Confusing the two can lead to prices that look profitable on paper but fall short of your actual target.
The Margin Method
If you have a target gross margin in mind, you work backward from the selling price rather than forward from cost. The formula is:
Selling Price = Cost Per Unit ÷ (1 − Target Margin as a Decimal)
Say your cost per unit is $100 and you want a 40% gross margin. Plug in the numbers: $100 ÷ (1 − 0.40) = $100 ÷ 0.60 = $166.67. At that price, $66.67 of every sale is gross profit, which is exactly 40% of $166.67.
This method is especially useful in retail, where businesses think in terms of margin rather than markup. If a grocery retailer targets roughly a 26% gross margin (a typical figure for that sector), and a product costs $2.00 wholesale, the formula gives: $2.00 ÷ (1 − 0.26) = $2.00 ÷ 0.74 = $2.70.
The margin method prevents a common error. If you simply added 40% of your cost to get a “40% margin,” you’d price the $100 item at $140, yielding only a 28.6% margin ($40 ÷ $140). The division formula corrects for the fact that margin is a share of the selling price, not a share of the cost.
Using Break-Even to Set a Price Floor
Both methods above tell you what to charge for a given profit target, but neither tells you the minimum price you can survive on. That’s where break-even analysis comes in. The U.S. Small Business Administration outlines the core formula as:
Break-Even Point (units) = Fixed Costs ÷ (Selling Price Per Unit − Variable Cost Per Unit)
You can rearrange this to solve for the selling price. If you know your fixed costs, your variable cost per unit, and how many units you expect to sell, you can find the price that makes revenue exactly equal total costs:
Break-Even Price = (Fixed Costs ÷ Expected Unit Sales) + Variable Cost Per Unit
For example, your business has $20,000 in monthly fixed costs (rent, salaries, insurance), a variable cost of $5.00 per unit, and you expect to sell 5,000 units. Your break-even price is ($20,000 ÷ 5,000) + $5.00 = $4.00 + $5.00 = $9.00. Sell at $9.00 and you cover every expense but earn zero profit. Any price above $9.00 generates profit; anything below means a loss.
The term “contribution margin” shows up in break-even discussions. It’s simply the selling price minus the variable cost per unit, divided by the selling price. It tells you what fraction of each dollar of revenue goes toward covering fixed costs and eventually generating profit. The SBA recommends adding about 10% to your break-even estimate to cover miscellaneous expenses you can’t predict, which gives you a more realistic price floor.
If some of your costs are semi-variable (they have both a fixed and a volume-dependent component, like a utility bill with a base charge plus usage fees), split them into their fixed and variable parts before running the calculation. The more precisely you categorize costs, the more reliable your break-even price will be.
A Step-by-Step Example
Suppose you manufacture candles. Here’s how to work through the full calculation:
- Direct materials per candle: $1.50 (wax, wick, fragrance, jar)
- Direct labor per candle: $0.75
- Manufacturing overhead per candle: $0.25 (allocated equipment and factory utility costs)
- Total variable cost per unit: $2.50
- Monthly fixed costs: $6,000 (rent, insurance, salaries not tied to production)
- Expected monthly sales: 2,000 candles
Your break-even price is ($6,000 ÷ 2,000) + $2.50 = $3.00 + $2.50 = $5.50. That’s your floor. Now decide on a profit target. If you want a 40% gross margin on the variable cost portion, use the margin formula: $2.50 ÷ (1 − 0.40) = $4.17. But notice that $4.17 is below your $5.50 break-even price, which means a 40% gross margin on variable costs alone won’t cover your fixed costs at this sales volume. You’d need to either raise the margin target, increase volume, or cut fixed costs.
A more realistic approach: you want to earn $2,000 in monthly profit on top of breaking even. Add that to fixed costs: ($6,000 + $2,000) ÷ 2,000 + $2.50 = $4.00 + $2.50 = $6.50. At $6.50 per candle, you cover all costs and pocket $2,000 a month, assuming you hit 2,000 units sold.
Gross Margins by Industry
If you’re unsure what margin to target, industry benchmarks offer a useful starting point. Gross margins vary widely depending on the sector, and data from NYU Stern’s January 2026 analysis shows the range clearly:
- Grocery and food retail: 26.3% gross margin
- General retail: 33.2%
- Restaurant and dining: 32.2%
- Food processing: 23.2%
- Apparel: 56.9%
- Computers and peripherals: 38.4%
- Healthcare products: 54.0%
- Auto and truck manufacturing: 10.4%
- Semiconductor: 59.0%
These are averages across publicly traded companies, so smaller businesses may see different numbers. But they show why a candle maker and an auto parts supplier would land on very different selling prices even if their per-unit costs were similar. The market you’re in shapes what customers will pay and what margins are sustainable.
Choosing the Right Method
Use markup pricing when you want simplicity and consistency across a large product catalog. It’s common in wholesale distribution and construction, where you apply a standard percentage to every item. Use the margin method when your business thinks in terms of profitability as a percentage of revenue, which is typical in retail and e-commerce. Use break-even pricing when you’re launching a new product and need to understand the minimum viable price before layering on a profit target.
In practice, most businesses combine these approaches. They calculate break-even to find the floor, apply a margin or markup formula to set the target price, and then adjust based on competitor pricing and what customers are willing to pay. The formulas give you a starting point grounded in your actual costs. The final price is a business decision that balances those costs against market reality.
