How do I factor shipping into my resale price?

Updated October 2026 · How we answer

Short answerCalculate your total shipping cost (postage, packaging, labels) and add it to your cost of goods, then set a price that covers both plus fees and profit. If you offer free shipping, build it into the item price.

Calculating Shipping Costs

Start by weighing and measuring your packaged item. Use a shipping calculator (USPS, UPS, FedEx) to estimate postage based on destination, weight, and dimensions. Don't forget packaging materials like boxes, bubble wrap, and tape—these can add $0.50 to $2 per item.

If you sell on marketplaces like eBay, you can offer calculated shipping (buyer pays actual cost) or free shipping (you build it into the price). Free shipping tends to attract more buyers, but you must ensure your price covers the cost.

  • Weigh and measure the packaged item.
  • Use online calculators for accurate postage estimates.
  • Include packaging supplies in your cost.
  • Consider dimensional weight for large but light packages.
  • Factor in shipping insurance for high-value items.

Pricing Strategy

If you offer free shipping, add the average shipping cost to your desired profit and fees. For example, if an item costs $10, fees are $3, shipping is $5, and you want $5 profit, your price should be at least $23.

If you charge for shipping separately, set the shipping cost to cover your actual postage and handling. Be transparent to avoid buyer dissatisfaction.

Common mistakes

  • Underestimating shipping costs by forgetting packaging materials or dimensional weight.
  • Offering free shipping without adding the cost to the item price, eating into profits.
  • Not accounting for shipping fee changes from carriers.
