Why owning your tools beats renting them.

A subscription rents you access. A one-time tool gives you control.

🔒

Your data stays local

Every product you evaluate is a competitive signal. Cloud calculators log your searches — that's how they build their datasets. This tool runs entirely in your browser. Zero network requests, verified by automated tests.

✈️

Works anywhere — no WiFi needed

Trade show. Factory floor. Supplier visit. Client meeting. Wherever you need to quickly check if a product makes sense, the calculator works. No login wall. No "connecting..." spinner. Just open the file.

⚡

No account before you calculate

Amazon's own calculator works without an account. Helium10 requires signup, email verification, plan selection. This tool: double-click the HTML file, enter your product, see the result. That's the entire onboarding.

📁

One file. Nothing to break.

65 KB HTML file. Works in Chrome, Firefox, Safari, Edge. No install, no updates that break your workflow. When Amazon changes fees, we release a new version — you download it once, same $26, no upgrade pricing.

What one-time buys vs. what subscriptions cost.

This isn't anti-Helium10. If you need keyword research, listing optimization, and PPC analysis — those suites make sense. If you need to know if a product is profitable, you don't need a suite.

One price. No tiers. No renewal.

Everything included. No "basic vs pro". No upgrade pricing.

Questions about the one-time model.

Yes. $26 via Gumroad. No auto-renewal, no "basic vs pro", no upsell after purchase. The tool is a single HTML file — there's no backend to bill you from. When we update fees, existing customers get the new version for free via Gumroad. That's how it works.

We release an updated version to Gumroad. All previous customers get a Gumroad notification email and can download the update for free. The fee tables are clearly labeled with their effective date so you always know what version you're running.

No — and it doesn't try to. Helium10 does keyword research, listing optimization, PPC analysis, review monitoring, and competitor tracking. Those are real capabilities. This tool does exactly one thing: calculates whether a product is profitable after all Amazon fees, with bulk import and offline capability. If that's what you need, this is the better choice. If you need the full suite, Helium10 is worth it.

Amazon's calculator is useful for single-product checks online. This tool adds: bulk CSV for 500+ products, offline functionality, break-even price calculation, Excel/CSV export, and the guarantee that your product data never leaves your machine. If you only need occasional single-product checks, Amazon's free calculator is fine. If you source regularly or need bulk analysis, this is the practical upgrade.
