How to Price a Product for Profit: A Step-by-Step Framework
Start from your true landed cost, add every variable cost per order (fulfillment, platform and payment fees, a return reserve, and target ad spend), then set a price that hits your target net margin on top of all of it. Pricing at a simple 2x markup of product cost usually fails because it ignores the fees and shipping that consume 30% to 50% of the sale.
Why the 2x markup rule fails
Keystone pricing (double your cost) was designed for brick-and-mortar retail with predictable overhead. In ecommerce, a 2x markup leaves you exposed because it does not account for outbound shipping, marketplace fees, payment processing, advertising, and returns. Those costs routinely consume 30% to 50% of the sale price.
Step 1: Calculate your true landed cost
Your cost basis is not the factory price. It is the landed cost: product cost plus inbound freight, duties, tariffs, and customs. Skipping these understates COGS and inflates your apparent margin from the very first calculation.
Step 2: Add every variable cost per order
- Fulfillment: outbound postage plus any pick-and-pack or 3PL fee.
- Platform fee: the marketplace referral or commission for your channel.
- Payment processing: typically about 2.9% plus a fixed amount per transaction.
- Return reserve: your expected return rate applied to revenue.
- Advertising: your realistic customer acquisition cost per order.
Step 3: Set price from a target net margin
Decide the net margin you need (often 15% to 25%), then work backward so the price covers landed cost plus all variable costs and still leaves that margin. This is the opposite of markup pricing: you are pricing to a profit outcome, not a cost multiple.
Price to your net margin target, not a markup on cost. A 50% markup can still lose money; a price set to a 20% net margin cannot, by definition, as long as your cost inputs are honest.
Step 4: Pressure-test with discounts and ad swings
Before you commit, model a 15% or 20% promo and a higher ad cost. If a routine discount or a bad ad week turns the product unprofitable, your price is too thin. Build the cushion in now rather than discovering it after launch.
Step 5: Reprice as costs move
Freight rates, ad costs, and fees all drift over time. Revisit your pricing every quarter, or whenever a major input changes, so a slow creep in costs does not silently erase your margin.
Frequently asked questions
What is a healthy net margin to target?
For most product businesses, 15% to 25% net margin is a durable target. Below 10% leaves little room for error; above 25% is strong but often invites competition.
Should shipping charged to the customer be part of the price?
Treat customer shipping as revenue and your actual postage as a cost. Offering free shipping simply folds that postage into the item price, so your price must be high enough to absorb it.
How do I price for multiple sales channels?
Each channel has different fees, so the same product may need a different price per channel to hit the same net margin. Compare them before setting prices.
