Question 1

What is an ecommerce profit calculator?

Accepted Answer

An ecommerce profit calculator takes your product cost, shipping, platform fees, ad spend, return rate, and other costs and calculates your true net profit per sale — not just gross margin. Profit Decision Engine goes further by including import tariffs, break-even price, launch cash requirements, and a clear go/pause/avoid verdict.

Question 2

Who is this ecommerce profit calculator built for?

Accepted Answer

Profit Decision Engine is built for ecommerce sellers, resellers, manufacturers, and importers who need to know the real net profit on any product before placing an order. It works for Amazon FBA, Shopify, eBay, Etsy, Walmart, and wholesale/direct channels.

Question 3

How is this different from a spreadsheet or basic margin calculator?

Accepted Answer

A basic margin calculator only shows gross margin. This ecommerce profit calculator includes every real cost: landed cost with tariffs, platform fees, payment fees, ad spend per sale, return costs, damage rates, and cash flow requirements — with a clean PDF report you can share with your team. No formula maintenance required.

Question 4

How accurate are the import tariff rates?

Accepted Answer

The tariff rates are based on US MFN (Most Favored Nation) rates and Section 301 surcharges by country of origin and product category. They are estimates — always verify your specific HTS code with a customs broker for large orders. You can override the rate manually if you know your exact duty percentage.

Question 5

Does this work for Amazon FBA sellers?

Accepted Answer

Yes. Select Amazon FBA from the channel preset dropdown and the calculator automatically fills in FBA referral fees and fulfillment fees. It then calculates your true net profit after all Amazon fees, your ad spend, return rate, and product cost — including import tariffs if you source from overseas.
