Netbasis sets the standard for securities cost basis calculation. This user-friendly web-based application draws on historical security pricing data extending back as far as 1925 to quickly and accurately determine the adjusted cost basis of virtually any security – regardless of its history of capital changes.

Netbasis makes it easy to determine adjusted cost basis, even when securities have been held for decades and have a complicated history of associated corporate actions. It can calculate cost basis using as little detail as the year of a security’s acquisition, and instantly accounts for historical changes caused by stock splits, mergers, dividend reinvestments and all other possible cost basis adjustments.
