Embed a free
reseller profit calculator.

Try the actual widget.

The default camera resale is fictional: $90 receipts, $30 acquisition, $12 fees, $8 shipping and $2 packaging leave $38 contribution for this transaction. It excludes an earlier refunded sale and is not full item-history profit.

Copy this code into an HTML/embed block.

Use a container at least 320 CSS pixels wide. Leave scrolling available, especially when help or validation messages expand. Increase the height if your layout needs it. The link outside the iframe is an accessible fallback.

Open the plain-text embed code

Some website editors and user roles strip iframe markup. Use an HTML/embed-capable block or the fallback link; compatibility with every CMS is not claimed. If your site uses a Content Security Policy, its frame-src policy must allow https://documentease.dev. No API key, account, remote form or checkout is needed.

A clear, bounded calculation.

Contribution = item sale + shipping received − acquisition cost − actual fees − shipping paid − packaging − other sale costs. The widget uses the same checked integer-cent calculation as our full free calculator ↗.

USD only. Enter 0–1,000,000 per field, up to two decimals. No fee presets, currency conversion, refunds, returns or prior sale history. Only entered costs are included; this is not complete business net profit or a tax calculation. The paid spreadsheet is optional and follows a separate manual desktop Google Sheets import workflow.

Privacy and link behavior.

The widget does not load PostHog or advertising scripts. Its code does not read or write cookies, local storage or session storage, and uses no parent-page messaging. Entered amounts and results stay in browser memory. It does not read the publisher URL, send calculations to a server or identify a publisher.

A hosted iframe still requests its page, CSS and JavaScript from documentease.dev and our hosting provider. Those ordinary requests can disclose IP address, browser and other technical request metadata. Depending on browser privacy settings, requests may include existing cookies for this domain; the widget code does not use them. The supplied no-referrer setting avoids sending the parent page URL in the iframe request. Your website may have its own tracking and consent requirements outside this widget.

All widget links use fixed HTTPS Studio destinations and open a new tab with no opener/referrer access. Preview and full-tool links carry only fixed widget campaign labels, never amounts or parent-page information. Optional first-party analytics on the destination starts only under that page’s analytics choice; the widget itself sends no analytics. A click does not prove a purchase or publisher adoption.

Keep the sandbox and fallback.

allow-scripts lets the local calculation run. allow-popups permits reader-clicked links to open. allow-popups-to-escape-sandbox keeps the destination tab usable instead of inheriting the widget restrictions. The supplied code does not grant same-origin access, forms, downloads or top-page navigation.

Do not add allow-same-origin just to run this widget. It uses a classic script, not a module or storage feature that needs that permission. The iframe title describes its purpose for assistive technology. No automatic resizing or parent messaging is used.

Commercial, editorial and educational pages may embed this hosted widget without a fee. No separate credit, backlink or reciprocal link is required. Keep the widget as served, including its visible Studio attribution and optional-product links. Buying the spreadsheet is optional and is never required to use the widget. This does not permit resale or redistribution of the paid workbook or imply a partnership. Availability may change; always check the input records and calculation before relying on a result.
