Codegres.org VS ProfitCalcu

ProfitCalcu's answer:

ProfitCalcu stands out because it brings six major marketplaces together in one free tool — Etsy, Amazon FBA, eBay, Shopify, Alibaba, and AliExpress — something no other free calculator offers. Unlike most tools that only show basic fees, ProfitCalcu factors in every hidden cost including Offsite Ads, FBA storage, eBay promoted listings, Shopify app costs, and import duties, so you always see your true net profit. Every calculation runs entirely in your browser, meaning your numbers never leave your device — no data collection, no tracking, completely private. There is no signup, no account, and no ads — just open the tool and start calculating instantly. All fee tables are manually updated for 2026, so you are always working with accurate numbers. And since the tool is fully mobile optimized, you can check your margins from your phone anywhere — at a warehouse, a market, or on the go.

ProfitCalcu's answer:

Most profit calculators online are either locked behind a signup wall, cluttered with ads, or only cover one platform at a time. ProfitCalcu removes all of that friction. It is completely free, requires no account, shows no ads, and covers all six major selling platforms in one place — Etsy, Amazon FBA, eBay, Shopify, Alibaba, and AliExpress. Where competitors show you a rough estimate, ProfitCalcu shows you the full picture. Every hidden fee is factored in — storage costs, promoted listings, import duties, ad spend, payment processing, and taxes — so the number you see is your actual take-home profit, not a guess.

ProfitCalcu's answer:

ProfitCalcu is built for anyone who sells products online and needs to know their real profit before or after a sale. The primary audience is online sellers who are serious about their margins — people who understand that platform fees, shipping costs, and taxes can quietly eat into profits if not tracked carefully.This includes Etsy sellers running handmade or print-on-demand shops who need to factor in listing fees, transaction fees, and offsite ads before pricing their products. It includes Amazon FBA sellers managing fulfillment costs, referral fees, and storage expenses across multiple SKUs. eBay resellers who deal with final value fees and promoted listings are a core part of the audience too.

ProfitCalcu's answer:

The idea came from watching sellers across Etsy, Amazon, and eBay constantly underpricing their products — not because they were careless, but because platform fee structures are genuinely complicated. Etsy alone has listing fees, transaction fees, payment processing fees, and offsite ads that can stack up to 20% of a sale. Amazon FBA adds fulfillment tiers, storage windows, and referral percentages that change by category. Most sellers were either ignoring these costs entirely or spending hours on spreadsheets trying to piece it all together. The existing tools were not good enough. Some required signups. Some showed ads that cluttered the experience. Most only covered one platform. None of them gave a seller a clean, honest, complete picture of their actual take-home profit across every major marketplace — in one place, for free. So ProfitCalcu was built to solve exactly that. No accounts. No ads. No data collection. Just a fast, accurate, private tool that tells you your real profit before you list — across Etsy, Amazon FBA, eBay, Shopify, Alibaba, and AliExpress. The goal was never to build a business around the tool. The goal was to build the tool that every seller wished already existed — and make it completely free, forever.

ProfitCalcu's answer:

ProfitCalcu is built entirely with core web technologies — HTML, CSS, and vanilla JavaScript. There is no backend, no database, and no server-side processing involved. Every calculation runs directly in the user's browser, which is also what makes the tool completely private by design. The frontend is a single-page architecture with custom CSS for theming, animations, and responsive layout across desktop and mobile. Dark and light mode switching, card interactions, and all calculator logic are handled purely through JavaScript without any frameworks or libraries. The site is hosted on GitHub Pages, which serves the static files globally with fast load times and zero server costs. There are no third-party APIs, no tracking scripts, and no external dependencies that could slow the experience or compromise user privacy. This lightweight, dependency-free approach was a deliberate choice — it keeps the tool fast, reliable, and accessible on any device or connection speed, anywhere in the world.
