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 is at or above your target ROI. Amber is above break-even but below target. Red is below break-even.
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
At or above your target ROI. When the price line spends time here, this product has historically hit your profit goal. This is where you want to see action.
~
Amber Zone
Above break-even, below your target ROI. You made money here, just less than you asked for. Worth considering if velocity is strong or you need to move capital.
✕
Red Zone
Below break-even. You lose money at these prices. If the price history dips into red often, that is the risk on this product. 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.
Three greens, buy. Fewer than three, walk. That is the whole discipline, and it is the same on your fifth ASIN of the day as your five hundredth.
Box Filler
Three gates: 40 cubic inches or less, 1 lb or less, 2 inches or less on the smallest side. Clear all three and the extension flags it as a Box Filler, a small, light item that rides along in space you were already shipping. Hazmat and heat-sensitive products are never flagged. Free, on every product page.
Your Price and FC Inventory
When you're logged into Seller Central, see your own live listing price on the chart against break-even and the market, and your own FBA units mapped by metro, including units in transit between fulfillment centers. Free on every product page, after you authorize the session. Across a whole list, they come with the Bulk Analyzer in Premium.
Variation Confidence
Keepa shows the parent's sales rank on every child, so rank cannot tell you which variation sells. One click scores the whole family on signals that belong to each child alone and gives every variation a Confidence Tier with plain-English reasons. It quotes the Keepa token cost before it spends anything. Free.

Proof
What Sellers Are Saying
“It adds a missing piece to the system. Quick and effective assessment of ASINs’ profitability, today and historically. I love it.”
Laith Hammo“A color-coded quick look eval of go/no-go on profit protection and profit potential. This really speeds up confirmation of purchasing for test. Fantastic.”
Gus Anderson“PATH Profit Zones makes it so easy to see if an ASIN is profitable. I can make a sourcing decision in seconds!”
Yamiel Semo“Everyone says ‘do the work,’ but that’s tough when you’re flooded with open-ended decision points every time you sit down. Now I build my system, trust it, and push the go button. 3 greens? Buy. No 3 greens? Move on. Pure execution.”

Premium
Price Smarter.
Price Smarter.
Margin Harder.
The free tool tells you if a product works. Premium helps you squeeze more margin out of every unit: price smarter across the country and run a whole sourcing list at roughly 600 ASINs an hour.
Buy Box by Metro
Nearly 4 in 10 ASINs price differently somewhere in the country. That gap is money you are leaving in another zip code. We read the Buy Box in up to 18 US metros so you know which kind you are holding: who is winning it, at what price, and how fast they deliver.
Bulk Analyzer
Run your whole sourcing list in one pass, roughly 600 ASINs an hour, and it comes back sorted instead of unread. No list limit. Zero tokens first: it reads the Keepa extension's cache and only calls the API for products the cache has never seen. Profit zones, 3-Step Check, and gating on every card.
Stock Gap DetectorBeta
Days of cover on what is actually buyable, so you spot a market about to run dry before the replen crowd does. Zero Keepa tokens in normal use. Includes the Offers Table: every live offer with seller ratings, price, stock freshness, and units moved in 30 and 90 days, plus a Buy Box tab showing who held the Buy Box over 90 days.

Seller Central features are 100% opt-in. You authorize each session and can pause anytime. Your Seller Central data is read and processed inside your browser and never leaves your device. On Premium we receive the ASIN and public product metadata, tied to your license key, to pre-warm the price-spread cache.
You Stay in Control of Your Data
The free tool runs on Keepa data. The exceptions are the sell-eligibility lock, Your Price, and FC Inventory, which read your own Seller Central account with your existing login, and only after you allow it for that browser session.
Account features are opt-in by design. You explicitly authorize Seller Central access each session and can pause or revoke it anytime.
Your Seller Central data is read and processed inside your browser and never leaves your device. On Premium we receive the ASIN and public product metadata, tied to your license key, to pre-warm the price-spread cache. Never your account data, never your credentials, never for sale.
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 all 10 Amazon marketplaces Keepa supports, including the US, Canada, UK, Germany, France, Japan, and India.
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.
Which variation actually sells?
Keepa shows the parent's sales rank on every child, so rank cannot tell you which variation sells. Variation Confidence scores the whole family in one click, on signals that belong to each child alone, and gives every variation a Confidence Tier with plain-English reasons. It quotes the Keepa token cost before it spends anything. Free.
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, the 3-Step Check, the Box Filler alert, Variation Confidence, Your Price, and FC Inventory are free forever. Premium adds Buy Box by Metro across up to 18 US metros, the Bulk Analyzer (which brings your Seller Central data to a whole list), and the Stock Gap Detector (Beta), for $9.99/mo or $95.90/yr.
Does it access my Amazon account?
Only with your explicit, per-session permission. Seller Central features (sell eligibility, Your Price, FC Inventory) are opt-in. Every Seller Central request identifies itself to Amazon as Agent/PathProfitZones, as Amazon's Agent Policy requires. You authorize each session and can pause or revoke anytime. Your Seller Central data is read and processed inside your browser and never leaves your device. On Premium we receive the ASIN and public product metadata, tied to your license key, to pre-warm the price-spread cache. Never your account data, never your credentials, never for sale.
