Embed our tools on your site
Drop the Etsy Fee Calculator, the Cottage Food Revenue Cap Tracker, the IRS hobby-vs-business test, the price-hike decision tool, or any of the other 24 interactive tools into your own page with one copy-paste snippet. Web Component or iframe — both render the same widget with the same math.
Free forever. No API key. No usage caps. The only ask is the "Powered by Ardent Seller" attribution link that ships with each snippet — that link is your contribution to keeping the tools free and updated.
Educational tools — not financial, legal, or regulatory advice. Embeds reflect Ardent Seller's published data at the time of last build; refresh by reloading the page. State cottage food laws, marketplace fees, and IRS thresholds change frequently — always verify against the authoritative source before relying on the output for a business decision.
The 24 tools you can embed
Each tool ships in two formats. Pick the one your platform supports. Both deliver the same widget and the same backlink.
Etsy Fee Calculator
Models all five 2026 Etsy fees (listing, transaction, payment processing, Offsite Ads, regulatory) across 9 countries plus true net profit per sale.

</p>Why embed?
Your audience gets the tool
A reader on your "how Etsy fees work" article doesn't have to leave for a calculator. The math is right there, in context. Bounce rate down, time-on-page up, the article does its job better.
You get the backlink
Each snippet ships with a visible "Powered by Ardent Seller" link from your page back to ours. That link is a dofollow backlink — it helps both our pages rank for the tool's target queries and adds value to your reader.
We keep the data current
When Etsy raises a fee, a state changes its cottage food cap, or the IRS updates a 1099-K threshold, the embed updates on its own — your readers see the current numbers without you having to touch the page.
No account, no key, no caps
The bundle is hosted statically. There's no rate limit, no usage cap, and no API key to manage. Drop it in and it works for as long as the tool exists.
Technical notes
The Web Component bundle is roughly 118 KB gzipped (JS + CSS combined). It registers all 24 custom elements; widgets share the same Angular runtime so embedding multiple tools on one page costs the runtime only once.
The iframe embed uses our /embed/{slug} route, which renders the same widget with no header, footer, or navigation. The route returns noindex,nofollow and its canonical URL points back to the full /resources/{slug} page so search engines attribute the tool's content to our canonical page (where it lives in topical depth) rather than your iframe shell.
Stable URL versioning: the bundle is served from /embed/v1/*. If we ever ship breaking changes to the widget API or markup, they go to /embed/v2/* — your existing snippet keeps working on v1 until you choose to update it.
Optional iframe auto-resize: drop our 1 KB resizer helper into your page and the iframe will auto-resize as the tool's content grows or shrinks. Without it, the iframe respects the min-height in the snippet and shows an internal scrollbar — a safe default if you'd rather not wire anything up.
Run a maker business yourself?
The tools you can embed are the free, simplified versions of the operations math Ardent Seller runs across your full product catalog every day — recipe costing, batch tracking, marketplace fee reconciliation, Schedule C–ready reports. Free to start, no credit card required.
The tools themselves
Etsy Fee Calculator (2026)
Live Etsy fee calculator updated for 2026. Enter item price, shipping, country, COGS, and ad spend — see listing, transaction, payment processing, Offsite Ads, and regulatory operating fees broken out line by line, plus your true net profit per sale.
Etsy Ads ROAS & Break-Even Bid Calculator
A free Etsy Ads break-even calculator. Enter item price, costs, conversion rate, and Etsy fees — and get the maximum average CPC your campaign can sustain and the break-even ROAS for your listing. Pairs with the Etsy fee calculator.
Sales Tax Nexus Checker (2026)
A free, scoped-for-small-sellers economic-nexus checker. Enter your trailing 12-month sales and transactions per state, and the tool flags every state where you have probably crossed the post-Wayfair economic-nexus threshold — without pushing you into a filing product.
Discount Strategy Simulator (Margin-Aware)
Compare BOGO, % off, $ off, and free-shipping promos side by side with your real margin. See the volume lift each promo needs just to break even — the counter-intuitive math most sellers get wrong.
Maker Hourly-Rate Pricing Calculator
Pick a target hourly rate, enter your materials, hands-on minutes per unit, and platform fees — the calculator returns the minimum price that actually pays you that rate after fees and costs. Maker-business specific, not a "freelance day rate" tool.
"Should I Quit My Day Job?" Maker Runway Calculator
A maker-business runway calculator. Enter savings, day-job income, current side-business profit, growth rate, and household expenses — and find out how many months until your craft business can actually replace the paycheck.
Cottage Food Revenue Cap Tracker
Pick your state, enter year-to-date gross sales, and see in real time how close you are to the cap that turns a cottage food operation into a regulated food business. Covers all 50 states + DC.
Should I Raise My Prices? Decision Tool
A live web tool that runs the +10% / +20% / +30% price-hike math for one product — including the volume drop that comes with each — and tells you which scenario clears the most monthly profit.
Candle & Soap Fragrance Load Calculator
Pick a wax or soap base, enter your batch size, and get the exact fragrance oil weight — plus the typical and max load for that medium and the cost per unit.
Hobby vs Business: IRS 9-Factor Test
Walk through the nine factors of Treasury Regulation §1.183-2(b) and find out whether your side activity qualifies as a for-profit business or a hobby for federal tax purposes — and where to focus to strengthen the business case.
1099-K Threshold Tracker (2026)
A multi-platform tracker that tells you which payment processors will send you a 1099-K this year under the post-OBBBA 2026 rules. Federal $20K + 200 transactions; ten states + DC trigger earlier.
