Build cost spreadsheet for a KiCad project.

Project description

KiCost script, also with Graphical User Interface - GUI, under MIT license for generate part-cost spreadsheets for circuit boards developed with KiCad and others EDAs.

KiCost is powered by the [Kitspace]( PartInfo API. [Partinfo]( hooks into paid-for 3rd party services. If you find KiCost useful please [donate to the Kitspace Open Collective]( If Kitspace doesn’t receive enough donations then this free service will have to be shut down.



  • Easy installation via pip (see on documentation folder).
  • Processes the BOM XML file from your KiCad schematic to create a part-cost spreadsheet by scraping the web sites of several popular distributors for price and inventory data. (You can also enter your own quantity-adjusted pricing data for specialized parts or those not found at the supported distributors.);
  • Processes also BOM files from Altium, Proteus, Eagle, Upverter and hand made CSVs;
  • The spreadsheet contains quantity-adjusted pricing from each distributor for individual parts and the total board;
  • Enter the number of boards to be built in a spreadsheet cell and all the pricing for the total board and individual parts is updated;
  • The spreadsheet also shows the current inventory on-hand for each part at each distributor;
  • Enter the quantity of each part that you want to purchase from each distributor and lists of part numbers and quantities will appear in formats that you can cut-and-paste directly into the website ordering page of each distributor.
