Get Started →Cost Calculation and Pricing
Proper pricing is the key to success in wholesale. Setting prices without accounting for all costs is the most common mistake.
Cost Components
| Cost Item | Description | Typical Range |
|---|---|---|
| Product Cost | Wholesale purchase price (per unit) | 40-60% of selling price |
| Inbound Shipping | Cost to get products to you | 3-10% per unit |
| Customs & Duties | Import: customs duty, VAT, tariffs | 5-30% of product cost |
| Outbound Shipping | Cost to ship to customer | 5-15% per unit |
| Marketplace Commission | Amazon, eBay, Walmart fees | 8-18% |
| Packaging | Boxes, tape, fill material | 1-3% per unit |
| Returns/Damage | Returned or damaged products | 2-5% of revenue |
| Storage | Warehouse rent, shelving, staff | Monthly fixed cost |
Pricing Formula
Selling Price = Product Cost / (1 - Target Margin - Commission Rate) Example: Product cost: $10 Target margin: 25% Commission: 15% Selling Price = $10 / (1 - 0.25 - 0.15) = $10 / 0.60 = $16.67

|---|---|---|
| Bulk buying without samples | Poor quality products, returns, loss | Always order samples first |

Conclusion
Wholesale buying and selling is an extremely profitable business model with the right product selection, reliable supply chain, and disciplined cost management. Never place large orders without samples, calculate all cost items, and follow a multi-channel sales strategy. Start with small batches to test, scale based on data, and aim to develop your own brand over time.
