PROFİT CALCULATE

While analyzing products on Amazon, I kept losing time switching between pages, tools, and spreadsheets. To minimize that friction, I built a tool called Marginix.

Marginix is a lightweight Chrome extension designed to make product analysis faster, clearer, and easier to understand at a glance.

Instead of opening multiple tools, it brings the most important decision metrics directly onto the Amazon product page:

• Profit
• ROI
• Break-even / minimum selling price

These are presented in a clean and easy-to-scan way, so you can quickly answer three key questions:
– Is there enough profit?
– Is the return worth it?
– How tight is the pricing margin?

The goal is not to replace advanced tools like Helium 10 or SellerAmp, but to act as a fast first filter before deeper analysis.

It helps you:
• Reduce time spent switching between tools
• Evaluate more products in less time
• Focus only on products worth deeper research

Marginix runs entirely within your browser, requires no login, and does not collect or store any personal data.

It’s built to feel simple, clear, and trustworthy — so you can make faster decisions without overthinking the numbers.

A more refined and improved version is currently under review — early access will be shared with a limited group once it’s approved.
