This RevSeller review covers what the extension actually does, what it costs, and where verified user reviews say it falls short — so you can decide before the 30-day trial ends. RevSeller is a single-purpose Chrome extension for online and retail arbitrage sellers: it overlays a live profit calculator and a variation viewer directly on the Amazon product page, so you can judge a sourcing deal without opening a separate spreadsheet or the Amazon Revenue Calculator. At $99.99/year it is one of the cheapest paid sourcing calculators on the market, but it is deliberately narrow, and it only works on Amazon.com and Amazon.ca.
TL;DR
- What it is: a Chrome-only overlay that shows ROI, profit margin, FBA/MFN seller counts, and every child variation’s data on the Amazon listing page — built for arbitrage buying decisions, not private-label research.
- Price: $99.99/year (billed as $8.33/month) or $19.99/month, with a 30-day free trial that requires no payment info (official pricing, data checked 2026-07-22).
- Best for: online arbitrage (OA) and retail arbitrage (RA) sellers who source on Amazon.com or Amazon.ca and want a fast, flat-rate profit check.
- Skip it if: you sell private label, need historical price/rank data, source outside the US/Canada, or want gating/restriction checks and bulk scanning — RevSeller does none of those.
- The honest caveats: verified reviewers report the FBA calculator drifting from Amazon’s own numbers, occasional “API error” failures on variation counts, and thin support. Treat those as your trial stress-test.

What Is RevSeller?
RevSeller is a browser extension that adds a profit-and-sourcing panel to the top of any Amazon product page. Instead of copying an ASIN into a calculator, you land on a listing and immediately see the numbers that decide an arbitrage buy: your ROI and margin at a given cost, the FBA and MFN seller counts, and the full grid of variations (size, color, pack) with each one’s rank and offer data.
That narrow focus is the whole point. Where a suite like Helium 10 tries to cover keyword research, listing optimization, and PPC, RevSeller does one job — “should I buy this unit to resell?” — and keeps it on a single screen. For OA and RA sellers scanning dozens of products a day, that speed matters more than breadth.
According to RevSeller’s official site (data checked 2026-07-22), the core panel includes:
- On-page, real-time calculator — enter your buy cost and see net profit, ROI, and margin after Amazon’s fees, without leaving the listing.
- ROI and profit margin displayed together, so you can compare deals on the metric you actually source by.
- FBA and MFN seller counts — how many sellers you’d be competing with, and on which fulfillment method.
- Variation viewer — the feature it’s best known for: every child ASIN’s data laid out at once, so a “hidden” best-selling variation doesn’t slip past you.
- Customizable layout and quick links to the resources you check most.
It is a Chrome extension only — the official site states it is “currently only available for use in the Google Chrome browser.” There is no Firefox, Edge, or Safari build, and no standalone web app or mobile version.
RevSeller Pricing (2026)
RevSeller uses one simple, flat structure — there is no tiered “Starter vs Pro” ladder and no per-feature upsell. Every subscriber gets the full extension.
| Plan | Price | Notes |
|---|---|---|
| Free trial | $0 for 30 days | No payment information required to start |
| Annual | $99.99/year | Billed as $8.33/month, paid annually |
| Monthly | $19.99/month | Same features, higher effective cost |

The math is the story here: at $99.99/year the annual plan works out to about $8.33 a month, which is why RevSeller is repeatedly cited by sellers of pricier rival extensions as the low-cost benchmark to beat. Two of the direct competitors below charge two to four times as much per month. If your only need is a fast profit-and-variation check on US/Canada listings, that flat annual price is hard to argue with — the question is whether the narrow feature set is enough for how you actually source.
What Reviewers Say
The quotes below are verbatim from third-party reviewers on the Chrome Web Store. They are not our own hands-on lab test — they are what real users reported, and they cluster around three themes worth stress-testing during your free trial.
1. Calculator accuracy versus Amazon’s own numbers. The most actionable complaint is that the on-page FBA math doesn’t always match Amazon’s calculator. One reviewer wrote: “The FBA calculator is always off when ever I compare it to amazon revenue calculator and their support really sucks. There is only an FAQ. I am going to look for a something better.” (Chrome Web Store, 1★, 2019-03-21). For a tool whose entire value is a profit number you’ll bet inventory dollars on, that is the one thing to verify yourself on a few known ASINs before you trust it at scale.
2. Occasional failures on the variation viewer. The flagship feature has also drawn error reports. One paying user described a recurring failure pulling variation review counts: “every time I try to find Review counts for the variations, I got the following error ‘API error’” (Chrome Web Store, 1★, 2021-09-19). Amazon changes its page structure often, and overlay extensions that scrape it can break until they’re patched — so intermittent errors like this are a known risk category for any on-page tool, not just RevSeller.
3. Support and roadmap responsiveness. Even a middling three-star review flags the same soft spot: “Good app. Not impressed with the answers and feedback on new feature ideas.” (Chrome Web Store, 3★, 2017-10-05). Combined with the “support really sucks… only an FAQ” comment above, the pattern is that RevSeller’s help is largely self-serve documentation rather than fast human support.
None of these is a dealbreaker on its own, and RevSeller has kept a loyal arbitrage following for years precisely because the core workflow is fast and cheap. But they tell you exactly what to test in the free trial: do the profit numbers match Amazon’s calculator, does the variation viewer load reliably on the ASINs you actually source, and can you live with FAQ-only support?
Where RevSeller Falls Short
Beyond the review themes, three hard limits are baked into what RevSeller is:
- Amazon.com and Amazon.ca only. The extension officially supports just the US and Canadian marketplaces (data checked 2026-07-22). If you source for Amazon UK, Germany, Japan, or any other locale, RevSeller cannot help you.
- No historical price or sales-rank data. RevSeller shows you the current state of a listing. It does not chart price or rank history — so to see whether today’s Buy Box price is a spike or the norm, you still need a dedicated price tracker like Keepa running alongside it. Most serious arbitrage sellers run both.
- No gating checks, hazmat flags, or bulk scanning. RevSeller won’t tell you whether you’re restricted from selling a brand, whether an item is hazmat, or let you scan a supplier’s whole catalog at once. It is a per-product decision tool, not a sourcing-automation platform.
If you’re new to arbitrage, it helps to understand the broader toolkit first — our guide to the best Chrome extensions for Amazon FBA sellers and the roundup of free Amazon FBA calculators both put RevSeller’s role in context, and our retail arbitrage primer explains where an on-page calculator fits into the sourcing workflow.
RevSeller Scorecard
The scores below reflect our analysis of RevSeller’s public documentation and verified user reviews (data checked 2026-07-22) against our 8-dimension scorecard methodology . They are informed judgment, not a controlled lab benchmark — we have not run a paid account through a hands-on test.
| Dimension | Score | Why |
|---|---|---|
| Accuracy | 3.0 / 5 | Core job, but reviewers report the FBA math drifting from Amazon’s own calculator — verify on known ASINs. |
| Ease of use | 4.5 / 5 | One on-page panel, minimal setup; the workflow is the reason it’s kept its following. |
| Depth | 2.5 / 5 | ROI, margin, seller counts, and variations — and nothing beyond that by design. |
| Automation | 2.0 / 5 | Per-product lookups only; no bulk scanning or list processing. |
| Team fit | 2.0 / 5 | A single-user browser extension with no team or role features. |
| Support | 2.0 / 5 | Largely FAQ-only; reviewers flag slow or thin help. |
| Pricing | 4.5 / 5 | $99.99/year flat, no tier upsells — among the cheapest paid sourcing calculators. |
| Stage fit | 3.5 / 5 | Strong for OA/RA on Amazon.com/.ca; a poor fit for private label or international sellers. |
The shape of this scorecard is consistent with what RevSeller sets out to be: cheap and fast at a narrow job, with accuracy and support as the areas to watch.
Who Should Use RevSeller — and Who Shouldn’t
Use it if you’re an online or retail arbitrage seller sourcing on Amazon.com or Amazon.ca, you make buy decisions one product at a time, and you want a flat, cheap profit-and-variation check that lives on the listing page. At roughly $8.33/month, a single avoided bad buy pays for the year.
Skip it if any of these describe you: you sell private label and need keyword, listing, and demand research; you source outside the US and Canada; you rely on price or rank history to time buys; or you need gating/restriction checks and bulk scanning to work at volume. RevSeller does none of these, and stretching it to fit will frustrate you.
RevSeller Alternatives
RevSeller’s closest direct competitors are the other on-page OA/RA calculators — SellerAmp SAS, AZInsight, and BuyBotPro. All three add features RevSeller lacks (gating and eligibility checks, more sourcing data, in some cases bulk workflows), and all three cost more per month, typically in the $20–$40/month range. If your bottleneck is sourcing decisions at scale rather than a fast single-product check, those are the natural upgrades to compare.
If you’re graduating toward private label and want research, keyword, and profitability tools in one suite rather than a standalone arbitrage calculator, Helium 10 is the broader platform most sellers move to — its Chrome extension includes a profitability calculator, and the suite adds keyword and listing tools RevSeller was never built for. (Note that its full Profits and P&L dashboard sits on the higher Diamond plan, not the entry tier.)
And if all you actually need is a free on-page fee check to sanity-test a deal before paying for anything, the AMZScout FBA fee calculator is a genuinely free tool for that single job. It won’t give you RevSeller’s variation viewer, but for basic profit math it costs nothing.

Frequently Asked Questions
Is RevSeller worth it? For OA and RA sellers on Amazon.com or Amazon.ca who make one-product-at-a-time buy decisions, the $99.99/year flat price is easy to justify — a single avoided bad buy covers it. It is not worth it for private-label sellers or anyone sourcing outside the US and Canada, because RevSeller doesn’t serve those workflows.
How much does RevSeller cost? $99.99/year (billed as $8.33/month) or $19.99/month, with a 30-day free trial that requires no payment information (data checked 2026-07-22).
Does RevSeller work on browsers other than Chrome? No. As of the data checked date (2026-07-22), the official site states it is only available for Google Chrome — there is no Firefox, Edge, Safari, or mobile version.
What marketplaces does RevSeller support? Amazon.com (US) and Amazon.ca (Canada) only. It does not support Amazon UK, Germany, Japan, or other international marketplaces.
Do I still need Keepa if I have RevSeller? In most cases, yes. RevSeller shows a listing’s current state but not its price or rank history, so arbitrage sellers typically run Keepa alongside it to see whether today’s price is a spike or the norm.
