The Problem
The Math That Costs You Money
Every product you look at requires the same exhausting calculation. And when you're wrong, you're stuck with inventory that bleeds cash.
Mental Math Overload
COGS plus prep plus shipping plus FBA fees plus referral fees, divided by... wait, what was my target ROI again? By the time you calculate, you've lost focus.
Spreadsheet Paralysis
The data is there. Somewhere. But you're looking at numbers, not answers. You see what the price was, not what your profit could have been.
Guessing Instead of Knowing
Most sellers look at today's price and hope for the best. They gamble instead of stacking the deck in their favor. And then wonder why they got burned.
The Solution
What If You Could See Potential Profitability?
PATH Profit Zones creates actual profit zones directly on a price history chart. Green means you could have hit your target ROI. Amber means you may have been profitable but below target. Red means you may have lost money.
No mental math. No spreadsheets. Just look at the colors and know instantly: Could this product have made me money?
Enter your cost of goods, your additional costs, and your minimum ROI. The extension does the rest, showing you exactly what your risks may be.
Profit Zones
Read the Zones. Make the Call.
Every color tells you something. Every zone is calculated based on YOUR numbers: your costs, your fees, your target ROI.
✓
Green Zone
Prices at or above your target ROI. When the price line spends time here, this product historically hits your profit goals. This is where you want to see action.
~
Amber Zone
You may have made money, just less than you wanted. Might be worth considering if velocity is strong or you need to move capital.
✕
Red Zone
You'd lose money at these prices. If the price history dips into red frequently, this product carries risk. Know before you buy, not after you're stuck.
The 3-Step Check
Your Risk Check, Visualized
Every profitable sourcing decision comes down to three questions. PATH Profit Zones answers them in one glance.
✓1
Sales Velocity
Does it sell? The extension shows if the item has sales velocity so you know you're not buying a brick. No velocity, no deal.
✓2
Capital Protection
Could you recover your investment? The zones show you break-even price history. If the price rarely drops below your floor, you're stacking the deck in your favor.
✓3
Profit Potential
Does it meet your ROI target? The green zone shows exactly when and how often the product has hit your minimum profit threshold over the time range you choose.

FAQ
Questions? Answers.
Do I need a Keepa subscription?
Not for most products. PATH Profit Zones reads the price data the free Keepa browser extension already caches on your machine, so it usually runs with zero API tokens. A paid Keepa API key is only used as a fallback when a product hasn't been cached yet. If you already run Keepa, you're all set.
What browsers does it work on?
Chrome and Edge (Chromium-based). The extension works on any Amazon marketplace, including the US, Canada, UK, Germany, France, Japan, and more.
Is it really free?
Completely free. No credit card, no trial that expires, no surprise charges. We built this to be genuinely helpful. If you find it valuable and want to learn more from us someday, that's a bonus, not the price of admission.
How is this different from just using Keepa?
Keepa shows you what prices were. We show you what your profit would have been at those prices. It's the difference between data and decision-making.
What if I'm new to Amazon FBA?
Even better. This tool teaches you to think about products the right way, visually understanding ROI, break-even, and capital protection from day one.
Do you offer training on how to use this?
Yes. There's a full PATH Profit Zones training community where we walk you through everything. Access the training here. That said, the tool is intuitive: enter your numbers, look at the colors.
Is there a paid version?
Yes. The Profit Zones extension and 3-Step Check are free forever. Premium adds the Buy Box Spread across up to 18 US metros, the Bulk Analyzer, Your Price, and FC Inventory, for $9.99/mo or $95.90/yr.
Does Premium access my Amazon account?
Only with your explicit, per-session permission. Premium's Seller Central features (Your Price, FC Inventory) are opt-in. You authorize each session and can pause or revoke anytime. Everything is processed inside your browser and never leaves your device. We never receive, store, or sell it.
