Local Etsy-style pricing extension

Price from profit, not guesswork.

Maker Margin Planner estimates marketplace fees, shipping, materials, packaging, labor, discounts, optional offsite ads, breakeven price, and target-margin price before you list.

One small tool for a daily seller decision.

Built for handmade, vintage, print-on-demand, and ecommerce sellers who need to model margin before discounting, shipping, or advertising eats the order.

Fee and cost model

Models listing, transaction, payment processing, optional offsite ads, materials, shipping cost, packaging, other costs, and labor.

Target price solver

Shows the item price required for a target profit margin, plus the breakeven price before you lose money.

Batch CSV planner

Paste listing scenarios from a spreadsheet and export results for quick margin review.

Local by default.

No marketplace login, no account connection, no analytics SDK, and no backend calculator. Your inputs stay in the browser.

No host permissions

The extension does not run on Etsy or any marketplace page. It is a standalone local calculator popup.

Editable assumptions

The US fee preset is included, but every fee field is editable because fees vary by account, country, currency, ads, and tax treatment.

Offline license code

Paid access uses a local license code. Activation does not send inputs or CSV rows to a server.
