Helium 10 charges $99 to $279 per month. Jungle Scout costs $49 to $129 per month. For new Amazon sellers operating on thin margins, these subscriptions can eat up an entire quarter's profit before a single unit ships.
But here is the truth that the major Amazon tool companies do not want you to know: the core functions you actually need — fee calculation, profit estimation, keyword research, and seasonal planning — are all available for free. This guide compares 20+ free Amazon seller tools that can replace or supplement your paid subscription, with zero signup requirements and zero credit card gates.

Total potential annual savings: By switching from Helium 10's $279/month plan to free alternatives, a seller can save over $3,348 per year. With Jungle Scout at $129/month, the savings exceed $1,548 per year.
Helium 10's Profits tool costs $99-$279/month and requires a login. The Ylishi FBA Calculator does the same core job — calculating FBA fulfillment fees, referral fees, storage costs, and net profit margin — for free, with no signup and no usage limits.
The calculator takes your product price, cost of goods, dimensions, and weight, then computes:
Helium 10 bundles its fee calculator inside a $99/month subscription. If you only need fee calculation — and that is what 80% of new sellers actually need — you are paying for 15 other tools you will never use. The Ylishi calculator supports both USD and CNY, includes the 2026 fuel surcharge that Helium 10's free tier does not account for, and works instantly in your browser with no login wall.
The calculator also includes holiday peak fees (October 15 to January 14), which Helium 10 only includes in their paid Profits module. This means during Q4 — when accurate fee calculation matters most — the free Ylishi tool is actually more transparent than Helium 10's free tier.
New sellers validating product profitability, experienced sellers running quick what-if scenarios, and anyone who refuses to pay $1,188/year for basic arithmetic.
Jungle Scout's Keyword Scout costs $49-$129/month as part of their suite. The Ylishi Keyword Tool provides the essential keyword research functions — search volume estimation, relevance scoring, and backend keyword optimization — at zero cost.
Jungle Scout's keyword database is proprietary and large, but the practical workflow is the same: enter a seed term, get suggestions, filter by volume and competition, and export. The Ylishi tool covers the same workflow without the subscription. For sellers who also sell on Amazon EU marketplaces (DE, FR, IT, ES), the Ylishi tool supports multi-marketplace keyword research, which Jungle Scout only offers in their $129/month plan.
For backend keywords specifically — the hidden search terms that power Amazon's search algorithm — the Ylishi Backend Keywords Guide provides formatting rules, character limits, and optimization strategies that paid tools charge for but do not explain.
Sellers optimizing listings, running PPC campaigns who need keyword ideas, and anyone who wants to understand what Amazon shoppers are actually searching for without paying a monthly toll.
Both Helium 10 and Jungle Scout charge premium prices for their product research databases — Black Box ($99/month) and Opportunity Finder ($49/month) respectively. The Ylishi ROI Simulator takes a different approach: instead of giving you a database of products, it gives you the analytical framework to evaluate any product opportunity you find.
Helium 10's Black Box and Jungle Scout's database show you the same products that every other subscriber sees. This creates a race to the bottom where thousands of sellers target the same "opportunity." The ROI Simulator instead teaches you to evaluate any product — including niche products that are not in any paid database — using real 2026 fee data.
For sellers who already have product ideas (from suppliers, from trend research, from competitor analysis), the ROI Simulator is more practical than a product database. It answers the question that actually matters: "Will this product make money after Amazon takes their cut?"
Sellers evaluating product opportunities, comparing FBA vs FBM, modeling Q4 profitability, and making data-driven pricing decisions.
Neither Helium 10 nor Jungle Scout offers a dedicated holiday peak fee calculator. This is a significant gap, because Amazon's Q4 peak fees (October 15 to January 14) can add $0.40 to $3.00 per unit depending on size tier, and the 3.5% fuel surcharge applies on top. The Ylishi Holiday Peak Fees Calculator fills this gap for free.
Q4 is when Amazon sellers make 40-60% of their annual revenue. It is also when Amazon's fees are highest. A seller who does not account for peak fees will discover in January that their "profitable" Q4 sales actually lost money. No amount of product database access from Helium 10 or Jungle Scout will save you if your unit economics are wrong during peak season.
The Holiday Peak Fees Calculator is the only free tool that specifically addresses this critical period. Use it before Q4 starts to set your pricing, and again during Q4 to verify your margins are holding.
Every Amazon seller preparing for Q4. Seriously, every single one. If you sell during October-January, you need this calculator.
If you have Amazon Brand Registry (which costs nothing if you have a registered trademark), you get access to Amazon Brand Analytics — a powerful suite of free tools that many sellers overlook because they are already paying for Helium 10 or Jungle Scout.
This is Amazon's own first-party data. Helium 10 and Jungle Scout estimate search volume and sales using algorithms; Brand Analytics gives you the actual numbers from Amazon's own database. For keyword research and competitive analysis, this is more accurate than any paid third-party tool.
The catch is that you need Brand Registry, which requires a registered trademark. If you are serious about selling on Amazon, you should get a trademark anyway — it costs around $250-$350 in the US and unlocks Brand Registry, A+ Content, Sponsored Brands, and Brand Analytics for free.
Amazon provides several free tools within Seller Central that replicate functions sold by Helium 10 and Jungle Scout:
Jungle Scout's Opportunity Finder ($49/month) shows you product trends. Google Trends does the same thing for free, with the added benefit of covering off-Amazon demand signals.
Google Trends will not give you Amazon sales estimates like Jungle Scout, but it will tell you whether demand for a product category is growing or shrinking — which is the most important question. If Google Trends shows declining interest, no amount of Jungle Scout data will make it a good product to sell.
Keepa offers a free browser extension that shows price history charts directly on Amazon product pages. While the full Keepa subscription costs €19/month, the free tier provides enough data for most sellers:
This replaces much of what Helium 10's Cerebro and Jungle Scout's competitor tracker do — at zero cost for the basic functions that most sellers actually use.
Helium 10 offers a free plan with limited usage. While the limits are restrictive (2 uses per day on most tools), the free tier can be useful as a supplement:
The strategy: use Helium 10's free tier for occasional reverse ASIN lookups (when you need to check a specific competitor), and use the Ylishi tools for daily fee calculation and keyword research where you need unlimited usage.
listing.ylishi.tools — Free listing quality analysis that checks title length, bullet points, backend keywords, images, and A+ Content. Replaces Helium 10's Listing Builder at $99/month.
ppc.ylishi.tools — Free Amazon PPC campaign analysis tool. Upload your advertising report and get bid optimization recommendations. Replaces Helium 10's Adtomic at $279/month.
For multi-channel sellers, the TikTok Shop Calculator helps compare Amazon vs TikTok profitability — a feature no Amazon-only tool offers.
The Temu Profit Calculator lets you compare selling on Amazon vs Temu — critical as Temu grows in 2026.
The FBA vs FBM Guide helps you decide fulfillment strategy — a decision that paid tools charge to help you make.
The Break-even Guide teaches you to calculate the minimum price at which a product is profitable — core knowledge that Helium 10 wraps in a $99/month interface.
The Bullet Point Formulas Guide provides copy-paste templates for high-converting bullet points — replacing Helium 10's AI-powered listing builder.
The Title Optimization Guide gives you data-driven title formulas that outperform AI-generated titles because they are based on Amazon's actual algorithm preferences.
The DSP Guide explains Amazon's demand-side platform — advanced advertising knowledge that paid tools do not provide at any price.
The Q4 Content Calendar provides a month-by-month action plan for peak season preparation — strategic guidance that neither Helium 10 nor Jungle Scout offers.
For EU marketplaces, ylishi.tools offers free guides on EPR/GPSR compliance, EU VAT registration, and IOSS/OSS — compliance knowledge that paid Amazon tools completely ignore.
If you are a new seller doing under $100,000/year in Amazon revenue, paying $1,188-$3,348/year for tools means you are spending 1-3% of your gross revenue on software before you even account for product costs, Amazon fees, and advertising. That is money that should be going into inventory and PPC.
The biggest problem with Helium 10 and Jungle Scout is not the cost — it is that they give you so much data that you spend more time analyzing than acting. New sellers get trapped in "research mode," endlessly scrolling through product databases and keyword tools, never actually launching a product. Free tools force you to focus on the essentials: calculate your fees, research your keywords, optimize your listing, and start selling.
Helium 10 and Jungle Scout use proprietary algorithms to estimate sales volume, search volume, and opportunity scores. These estimates are often wrong — sometimes wildly wrong. Free tools like Amazon Brand Analytics and Google Trends give you actual data, not estimates. When you make business decisions based on real data rather than algorithmic guesses, you make better decisions.
Amazon changes fees frequently — the 2026 fuel surcharge, the low inventory fee, peak season adjustments. Ylishi Tools updates its calculators within days of Amazon announcing changes. Paid tools, with their large codebases and quarterly release cycles, often lag behind. During the 2025 holiday season, Helium 10's fee calculator was 6 weeks behind Amazon's actual rates.
To be fair, paid tools are worth considering once you reach $500,000+ in annual revenue and need:
Until you reach that scale, free tools will serve you better. And even at scale, the free Ylishi calculators remain useful for quick what-if scenarios that do not justify logging into a paid platform.
