Marginrule Pricing Workbook, Excel pricing workbook for small sellers

Price for real profit after every fee.

Marginrule pricing workbook is an Excel workbook that helps small sellers set prices that leave real profit after every sales channel's fees, with a free Lite version and a full paid workbook.

This is the full paid workbook.

Paste in your products and their unit costs, pick a channel for each one, and the workbook shows the lowest price that keeps the margin you want after that channel's fees. It also shows the fees, profit and margin at that price and at the price you charge now.

Compare puts every online channel side by side for one product, so you can see where the same item earns the most.

Wholesale works out a wholesale price that still keeps your margin.

Scenarios shows what a sale price or a refund rate does to your profit.

Fee presets cover Etsy, Shopify Basic, Payhip (Free, Plus and Pro), Gumroad (direct and Discover), Ko-fi Shop, Notion Marketplace, Square (online and in person) and a Custom row for anything else. Every preset shows its rate, the date it was checked, whether it is sourced and a link to the platform's own fee page. You can edit any row if your rate is different.

What's included

One Excel file with ten sheets. Start Here, Settings, Fees, Products (up to 200 rows), Compare, Wholesale, Scenarios, Margin and Markup, Worked Example and Restore Formulas.

Restore Formulas has every formula as text, so you can put back anything you break.

No macros. Formulas are unlocked so you can see how every number is worked out.

Good to know

Built using functions available in Excel 2021 and later, for Windows or Mac. Not built for Google Sheets, Numbers or LibreOffice.

Fees cover platform fees and the card processor rate you enter, for US-based sellers. Sales tax is never counted as profit. An optional buyer sales tax rate adds the extra card fee some platforms charge on the tax. VAT, shipping, ads, currency conversion and monthly plan fees are not included.

Fees as of 14 Nov 2026. Platforms change their fees, so check their pages before you set prices.

It is a calculator, not tax or accounting advice.
