What is an Amazon FBA Calculator?

An Amazon FBA calculator is a tool that estimates the fees and potential profitability of selling products on Amazon using Fulfillment by Amazon (FBA) services.

Selling on Amazon comes with many fees, including:

  • Referral fees: A percentage fee charged per item sold, usually 8-45%.
  • FBA fees: Fees for picking, packing, labeling (optional), shipping, storing, and handling returns.
  • Monthly storage fees: Based on the size of items stored in Amazon warehouses.

The FBA calculator factors in these fees, product details like size and sales price, and seller inputs like number of units stored/sold to estimate:

  • Cost per unit: Your total expenses per item.
  • Net profit per unit: How much you earn per sale after fees.
  • Net margin: Your total profit margin percentage.

Amazon provides an FBA calculator in Seller Central, but third-party calculators also exist.

When to Use the FBA Calculator

It's wise to use an FBA calculator:

  • When evaluating a new product: Calculate potential ROI and compare fulfillment options.
  • To set prices: Find the optimal price for profitability.
  • If considering FBA: Decide if it makes financial sense over self-fulfillment.
  • To forecast inventory needs: Estimate how many units to store to meet sales demand.
  • When sales or costs change: Recalculate profitability as your business evolves.
  • Business Planning: The calculator can help you develop a solid business plan if you're just starting out.

Having accurate profit estimates helps you to make data-driven decisions about products, pricing, services, and more.

How Does the FBA Calculator Work?

FBA calculators take inputs about your product and business to estimate fulfillment costs. Here's what goes into the calculations:

Product details:

  • Size - packaging dimensions
  • Weight
  • Category (affects fees)
  • Sales price

Seller inputs:

  • Average monthly units stored
  • Estimated monthly units sold
  • Cost per unit

Amazon fees:

With this data, the calculator displays:

  • Estimated cost per unit
  • Net profit per sale
  • Total profit for estimated monthly sales
  • Profit margin percentage

You can experiment by tweaking the variables to model different scenarios.

How to Use an Amazon FBA Calculator

Follow this step-by-step process:

Step 1: Access the Amazon FBA Calculator

You have two options:

  • Sign in to your Seller Central account and search for “Revenue Calculator.” Next, open the ‘Revenue Calculator’ Help page and follow the provided link.
  • If you're not an Amazon seller (yet!), you can simply use the public version of the calculator and continue as a guest.

There are also some third-party FBA calculators that you can use for different purposes, like fee calculators, PPC cost calculators, and so on. They often provide more features and flexibility, but we’ll confine our discussion to using the official tool only for this blog.

Step 2: Enter Your Product Details

On the ‘Revenue Calculator’ page, you can search for existing products in the Amazon catalog or enter product information to define a new product.

Select the' Search Amazon catalog' tab to view cost and profitability estimates for selling a currently listed product.

Next, choose the Amazon store where you plan to sell the product to find relevant products, programs, and fee rates specific to that store. Once selected, enter the product’s SKU, title, ISBN, UPC, EAN, or ASIN, and click ‘Search.’

If the product you’re searching for is currently listed in your catalog in this Amazon store, it’ll appear under ‘My products.’

If the product isn’t currently listed in your catalog in this Amazon store, select the correct product under ‘Other products on Amazon.’

Select the 'Define product' tab to estimate the cost and profitability of selling a product not currently listed in your or Amazon catalogs.

Next, enter the product’s:

  • Size dimensions
  • Weight
  • Sales price
  • Shipping charge

You'll also need to select the Amazon store in which you plan to sell the product and the product's category.

Once complete, select ‘Estimate.’

Step 3: Estimate Inventory & Sales

As mentioned, the Revenue Calculator is an excellent tool for comparing the estimated net proceeds across fulfillment programs, including your fulfillment and FBA.

To start comparing, complete the required fields in the ‘Amazon Fulfillment’ and ‘Your fulfillment’ columns.

Under ‘Amazon Fulfillment,’ input:

  • The product’s sales price
  • Average units stored per month
  • Estimated units sold per month

Consider seasonality, ad spending, and sales velocity.

Under ‘Your fulfillment,’ enter:

  • The product’s sales price and shipping charge to the customer
  • Costs associated with your fulfillment and storage

Step 4: Factor in Costs

Next, enter:

Include all costs to purchase and deliver units to Amazon.

Step 5: Review Fees & Profit Margins

See estimated:

  • Referral fees
  • FBA fees per unit
  • Total monthly storage fees

Once complete, your cost per unit, estimated net profit, and net margin for each fulfillment method will be displayed at the bottom of each column.

Note that only some fees are included in these estimates. Fees not calculated in estimates include long-term storage fees, removal order fees, return processing fees, and more.

Step 6: Experiment with Inputs

Try different:

  • Price points
  • Monthly sales volumes
  • Products & bundles
  • FBA services

See how tweaks impact your bottom line.

You can also use the third column to compare another fulfillment scenario by entering different prices or cost estimates.

There is a new “Comparison graph” tab in the third column that will help you gauge everything visually.
