There is no single price that guarantees maximum profit for every product. Start by calculating what each sale contributes after variable costs, then use customer value and comparable offers to set a plausible range. Finally, compare the profit from realistic price-and-volume scenarios and update your estimate as sales data comes in.
Step 1: Calculate your costs and break-even point
Begin with the costs of making and selling one unit, then identify the fixed costs for the period you are evaluating. Variable costs change with each unit sold; depending on the business, they may include materials, production labor, packaging, or other per-sale expenses. Fixed costs are expenses that do not rise directly with each additional unit during that period. Shopify recommends understanding costs such as materials, labor, and other production expenses before setting a price (Shopify Help Center: Pricing your products).
Find contribution per unit
Contribution per unit = selling price − variable cost per unit. This amount goes toward covering fixed costs; what remains after all relevant costs are covered is profit. A positive contribution does not by itself mean the business is profitable: enough units must sell to cover fixed costs and any other costs included in the calculation.
Estimate break-even units
The U.S. Small Business Administration (SBA) gives this break-even formula:

#1 Best Overall
Break-even units = fixed costs ÷ (price per unit − variable cost per unit)
For example, if fixed costs for a period are $6,000, the assumed price is $30 per unit, and variable cost is $18 per unit, contribution is $12 per unit and estimated break-even volume is 500 units for that period. This is an illustration of the formula, not a forecast. The estimate is only useful if the period and cost inputs reflect your business. The SBA defines break-even as the point where total cost and total revenue are equal, with no loss or gain (SBA: Break-even point).
Rank #2
The SBA also defines the contribution-margin ratio as (price − variable cost) ÷ price. It shows the share of each dollar of sales available to cover fixed costs and then profit; it does not tell you how many units customers will buy. Break-even assumes a price and estimates the volume needed to cover fixed costs. It is not the price that maximizes profit.
Step 2: Set a market-informed price range
Use costs, customer value, and comparable offers to identify prices worth evaluating. These are different lenses, not interchangeable formulas or guarantees of a profitable price.
| Approach | Question it helps answer | What it cannot establish alone |
|---|---|---|
| Cost-plus | What price results if you add a chosen markup to cost? | Whether customers will accept that price or whether the markup covers all relevant costs. |
| Value-based | What might customers pay given the benefits or outcomes they perceive? | The actual willingness to buy at a particular price without customer or sales evidence. |
| Competitive | How are comparable offers priced and positioned? | Whether matching or undercutting those prices will be profitable for your business. |
Shopify recommends reviewing comparable products positioned above and below the market range and using customer reviews to understand what buyers value. Look for differences that matter to your target customer—such as features, quality, service, or a specific outcome—and consider whether they support a higher or lower price. Competitor prices are reference points, not proof that your costs or likely sales volume match theirs.
A cost-plus calculation can help identify a starting point, but an arbitrary markup does not establish profitability. Check that your proposed price covers variable cost and contributes toward fixed costs, then assess whether the product’s value and market position make the price plausible.
Step 3: Compare price-and-volume scenarios
Profit depends on both the contribution per sale and the number of sales. A higher price can produce more contribution per unit but may reduce the number of customers willing to buy; a lower price may attract more buyers while leaving less contribution per sale. Shopify notes that price affects both profit from a sale and a target audience’s willingness to purchase.
For each plausible price, estimate or test demand, calculate contribution, and subtract the costs relevant to the period. A simple comparison is:
Estimated operating profit for the period = (price − variable cost per unit) × expected units sold − fixed costs
This simplified calculation works only if the costs included are complete for the decision. Add other costs that apply to the business when they are not already reflected in variable or fixed costs. Do not treat an assumed sales volume as established demand.
| Scenario | Price per unit | Variable cost per unit | Expected units | Contribution before fixed costs |
|---|---|---|---|---|
| A | $30 | $18 | 500 | ($30 − $18) × 500 = $6,000 |
| B | $35 | $18 | 400 | ($35 − $18) × 400 = $6,800 |
In this illustration, Scenario B contributes $800 more before fixed costs, but only under the stated volume assumptions. If expected volume at $35 is lower, its result changes; the table does not show that either price is optimal. Compare plausible estimates and, where feasible, test prices with actual customers or sales. Replace assumptions with observed results over time rather than labeling an untested figure the maximum-profit price.

In the United States, the Federal Trade Commission (FTC) says truthful-advertising standards apply to sale and comparison-price claims. Do not use a “was” price, discount, or comparison that misleads customers about the offer (FTC: Advertising FAQ’s: A Guide for Small Business). State and local requirements may also apply; the FTC advises businesses to check with their state Attorney General.

The FTC’s Unfair or Deceptive Fees Rule took effect May 12, 2025, and applies to live-event tickets and short-term lodging—not to every product category. For covered transactions, businesses generally must disclose the total price upfront, subject to limited exclusions that must be disclosed before payment. The FTC FAQ says dynamic pricing is allowed under the Rule when pricing information is not misleading (FTC: The Rule on Unfair or Deceptive Fees: Frequently Asked Questions). Applicability to a particular seller or transaction depends on the Rule and relevant law.
