Shipping costs can make or break your profits on Amazon. Whether you use Fulfillment by Amazon (FBA) or Fulfillment by Merchant (FBM), understanding how shipping costs work is key to running a successful business. Thankfully, Amazon provides shipping cost calculators to help sellers estimate their expenses before listing products.
In this guide, we’ll break down how Amazon’s shipping cost calculators work, how to use them, and some best practices to keep shipping costs in check.

Amazon’s Shipping Options Available for Merchants
Before diving into the calculators, let’s quickly go over the two main ways sellers fulfill orders on Amazon:
1. Fulfillment by Amazon (FBA)

With FBA, you send your products to Amazon’s warehouses, and they handle storage, packaging, and shipping for you. It’s a hassle-free option, but Amazon charges fees for storage and fulfillment.
2. Fulfillment by Merchant (FBM)
With FBM, you store and ship products yourself. This gives you more control, but you’re responsible for packaging, shipping rates, and customer service.
Each method comes with different costs, which is why using Amazon’s shipping cost calculators is so important.
Amazon FBA Shipping Cost Calculator
If you’re using FBA, Amazon will charge fees based on your product’s size, weight, and storage time. The Amazon FBA Calculator helps sellers estimate these costs before they decide on pricing.
How to Use the FBA Calculator?
Here’s how you can use the FBA shipping calculator:
- Go to the Calculator – You can find the FBA calculator on Amazon Seller Central or use a third-party tool like Freightos.
- Enter Product Details – Type in your product’s size, weight, and price.
- Review the Cost Breakdown – The calculator will show Amazon’s fulfillment fees, including storage and shipping.
- Adjust Your Pricing – Use the data to set competitive prices while keeping a healthy profit margin.
Why the FBA Calculator is Important?
- It prevents pricing mistakes that could cut into your profits.
- Helps sellers decide if FBA is the right choice or if FBM might be cheaper.
- Keeps sellers updated on any fee changes by Amazon.
Amazon FBM Shipping Cost Calculator
If you choose FBM, you’ll need to figure out your own shipping costs. Amazon lets sellers set their own shipping rates, but it’s crucial to ensure you don’t overcharge or undercharge customers.
Steps to Calculate FBM Shipping Costs
- Use a Carrier’s Shipping Calculator – Visit UPS, FedEx, or USPS websites to estimate shipping costs based on your product’s weight and size.
- Set Your Amazon Shipping Rates – Inside Seller Central, create a shipping template that includes your preferred shipping methods and rates.
- Factor in Packaging Costs – Don’t forget to include boxes, labels, and packing materials in your final cost.
- Monitor & Adjust – Keep an eye on actual shipping expenses and adjust your rates as needed.
Amazon Multi-Channel Fulfillment (MCF) Calculator
Amazon’s Multi-Channel Fulfillment (MCF) allows sellers to use Amazon’s fulfillment services for orders from other platforms like Shopify or eBay. The MCF Shipping Calculator helps sellers estimate costs for these orders.
How to Use the MCF Calculator
- Visit Amazon’s MCF Calculator – You can find it on the Amazon Supply Chain blog.
- Enter Product Information – Add size, weight, and shipping details.
- Choose Shipping Speed – Compare costs for Standard, Expedited, or Priority shipping.
- Review Estimated Costs – Use the results to decide if MCF is the right fit for your business.
Tip: MCF can be a great option if you sell on multiple platforms but don’t want to handle fulfillment yourself.
Best Practices to Keep Shipping Costs Low
Shipping costs can eat into your profits if you don’t manage them well. Here are some smart ways to cut down on shipping expenses:
- Avoid oversized boxes to reduce dimensional weight charges.
- Use poly mailers or bubble wrap instead of heavy boxes when possible.
- Check USPS, UPS, and FedEx to find the most cost-effective option.
- If you ship in high volumes, you may qualify for discounted rates.
- Increase product prices slightly or set a minimum order value to cover costs.
- Amazon changes fulfillment fees regularly, so stay informed.
- Large, low-cost items may not be profitable with FBA due to higher fees.
- For FBM, set up custom shipping templates in Amazon Seller Central to control costs.
