About the E-commerce Cost-Plus Pricing Calculator

Cost-plus pricing is the simplest and most straightforward pricing strategy: take your total cost per unit and add a markup percentage to determine the selling price. It guarantees a profit on every sale as long as your cost calculation is accurate.

For e-commerce sellers, total cost includes not just the product purchase price but also shipping, fees, packaging, and any other per-unit expenses. This calculator accounts for all cost components and applies your desired markup to determine the selling price.

While cost-plus pricing ignores market demand and competitor pricing, it serves as an excellent floor price โ€” the minimum you should charge to achieve your target profit. Many sellers use cost-plus as a starting point and then adjust based on market conditions.

When This Page Helps

Cost-plus pricing ensures you never sell below cost. This calculator includes all e-commerce cost components that many sellers forget, giving you a more accurate base price. Use it to establish minimum prices and compare against market rates.

How to Use the Inputs

  1. Enter your product cost (landed cost or COGS).
  2. Enter platform fees as a percentage.
  3. Enter shipping and packaging costs.
  4. Enter your desired markup percentage.
  5. View the calculated selling price and resulting margin.
  6. Adjust the markup until you reach your target selling price or margin.
Formula used
Total Cost = Product Cost + Shipping + Packaging + (Selling Price ร— Fee%) Selling Price = Total Fixed Costs / (1 โˆ’ Fee% โˆ’ Markup Margin) Alternatively: Selling Price = Total Cost ร— (1 + Markup%)

Example Calculation

Result: Selling Price: $28.24 | Profit: $9.41 | Margin: 33.3%

Fixed costs: $12 + $3 + $1 = $16. With a 15% platform fee and 50% markup target: Selling Price = $16 / (1 โˆ’ 0.15) ร— 1.5 = $18.82 ร— 1.5... Using simple cost-plus: Total estimated cost including 15% fees on a $24 price = $16 + $3.60 = $19.60. Markup: $19.60 ร— 1.50 = $29.40. Iterating converges to ~$28.24.

Tips & Best Practices

  • Include ALL costs in your base: product, shipping, packaging, labeling, prep fees, and inspection.
  • Account for platform fees by working backward from the selling price.
  • A 100% markup equals a 50% margin โ€” don't confuse the two.
  • Use cost-plus as your floor price, then adjust up based on competitor pricing and perceived value.
  • For seasonal products, use a higher markup during peak demand to offset slow periods.
  • Revisit cost-plus calculations whenever supplier prices, shipping rates, or platform fees change.

Cost-Plus vs. Value-Based Pricing

Cost-plus pricing is internally focused โ€” it ensures profitability per unit. Value-based pricing is externally focused โ€” it charges based on the perceived value to the customer. The best e-commerce pricing strategies use cost-plus as a floor and value-based pricing as a ceiling, setting the actual price somewhere in between.

Accounting for Platform Fees

Platform fees create a circular calculation because they're based on the selling price. To solve this: Fixed Costs / (1 โˆ’ Fee Rate) gives the break-even selling price. Then apply your markup on top. This approach ensures your markup is truly above all costs including platform fees.

Dynamic Cost-Plus

Advanced sellers adjust their cost-plus markup dynamically based on demand, competition, and inventory levels. During peak seasons, increase the markup. During clearance, reduce it to just above break-even. This hybrid approach captures more value while maintaining a profitability floor.
