Selling online means the same few sums over and over: what the marketplace keeps, what the payment processor keeps, what is left after the cost of goods, and what price makes the margin you need. This page collects the Keywords Everywhere tools that answer them: fee calculators for Amazon FBA, eBay, Etsy, PayPal, and Stripe with the 2026 rates filled in and every rate editable, margin, markup, and discount calculators for pricing, an eBay keyword tool that harvests the phrases real shoppers type into eBay and adds Google search volume to each one, a product name generator with a .com availability check, a barcode generator for EAN-13, UPC-A, Code 128, and more, and an invoice generator that prints or saves as a PDF. Each marketplace also has its own page: Free Amazon Tools, Free eBay Tools, and Free Etsy Tools; this page keeps listing all of them together.
They are genuinely free: no signup, no trial, no credit card, and nothing connects to your Amazon, eBay, Etsy, PayPal, or Stripe account. The calculators, the barcode generator, and the invoice generator run entirely in your browser, so your numbers never leave it. The product name generator draws from a daily usage allowance that keeps it fast for everyone, and the eBay keyword tool has a daily keyword allowance for the search-volume lookups; signing in with a Keywords Everywhere API key raises those limits on paid plans, and every plan has a cap.
Yes. Every tool on this page is free to use with no signup and no credit card. The fee, margin, markup, and discount calculators, the barcode generator, and the invoice generator run in your browser with no allowance at all. The product name generator and the eBay keyword tool draw from a daily allowance that keeps them fast and fair for everyone, and signing in with a Keywords Everywhere API key raises it on paid plans; every plan has a cap.
29 free eCommerce tools right now: eBay Fee & Profit Calculator, Etsy Fee Calculator, Amazon FBA Revenue Calculator, eBay Keyword Tool, Amazon ACoS Calculator, KDP Royalty Calculator, KDP Cover Size Calculator, eBay Shipping Calculator, Etsy Shipping Calculator, Etsy Image Resizer, eBay Image Resizer, Amazon Image Resizer, Etsy Tag Generator, Etsy Shop Name Generator, eBay Store Name Generator, Amazon Link Generator, eBay Listing Template Generator, Amazon ASIN Lookup, Amazon Product Research Tool, Amazon Price Checker, Amazon Keyword Tool, PayPal Fee Calculator, Stripe Fee Calculator, Margin Calculator, Markup Calculator, Discount Calculator, Product Name Generator, Barcode Generator, and Invoice Generator. New Amazon, eBay, and Etsy tools appear here as they launch, and each marketplace has its own page: Free Amazon Tools, Free eBay Tools, and Free Etsy Tools.
Each one ships with the published 2026 rates: eBay 13.6% final value fee plus a $0.30 or $0.40 per-order fee, Etsy $0.20 listing plus 6.5% transaction plus 3% and $0.25 processing, Amazon 15% referral with the $0.30 minimum, PayPal 2.99% plus $0.49, Stripe 2.9% plus $0.30. Marketplaces change their rates and vary them by category, country, and seller level, so every rate is an editable input: type the rate from your own seller dashboard and the maths follows. The Amazon FBA fulfillment fee depends on your product's size tier, so you enter it from Amazon's fee table rather than trusting a default.
Start from cost. The Margin Calculator turns a cost and a target margin into the price you need; the Markup Calculator does the same from a markup percentage and shows the equivalent margin, since the two are often confused. Then run that price through the fee calculator for the marketplace you sell on to see what actually lands in your account after fees. If the take-home is too thin, raise the price or the target margin and run it again. The Discount Calculator shows what a sale price does to the number.
Not here, and we would rather say so than ship a tool that breaks. eBay exposes a public suggestion endpoint that a browser can call, which is what the eBay Keyword Tool uses. Amazon's endpoint refuses requests from other websites and Etsy's sits behind bot protection. For general product demand, the Google Keyword Tool and the Search Volume Checker give Google's search volume for any product term, which tracks marketplace demand well for most categories.
No. Nothing here connects to Amazon, eBay, Etsy, PayPal, Stripe, or any store platform, and no tool asks for a password or an API key of yours. The calculators work from the numbers you type, the eBay keyword tool reads eBay's public suggestions from your own browser, and the barcode and invoice generators never send anything to us.
The Barcode Generator encodes EAN-13, EAN-8, UPC-A, Code 128, Code 39, and ITF and computes the check digit for you, so the image scans. What it cannot do is issue the number: a GTIN (the 12 or 13 digits under a retail barcode) has to be licensed from GS1 before Amazon or a retailer will accept it. Use the tool to render the barcode for the number you already own, for internal SKUs, or for shipping labels.
The client-side tools have no limit. The product name generator has a per-day usage allowance so that a few heavy users cannot slow it down for everyone, and the eBay keyword tool has a daily keyword allowance because each search-volume lookup costs us an API call. The free allowances are generous for typical use; signing in on a paid Keywords Everywhere plan raises the daily caps. Every plan has a cap, higher tiers simply get a higher one.
