costbas - Calculate cost basis from Quicken QIF data
costbas.rb is a Ruby script that reads QIF files from Quicken and produces a report showing share lots after each transaction and the cost basis for each stock or mutual fund sale transaction. It calculates the cost basis using two methods, FIFO and average cost basis, and cost basis figures are separated into short-term and long-term.

- Under "Include in Export", select only "Transactions" and leave the rest unchecked.
- Click on OK.
Run the following command to generate a report to stdout:
ruby costbas.rb qdata.QIF
where qdata.QIF is the name of the QIF file you exported.
