Adjusted Cost Basis

Definition

Adjusted cost basis represents the net financial investment in an asset after accounting for various capital adjustments, effectively serving as the baseline for determining realized gains or losses upon liquidation. In cryptocurrency and derivatives trading, this metric integrates the original purchase price with additional expenses such as transaction fees, commissions, and relevant corporate actions or blockchain-specific events like protocol forks. It functions as the primary quantitative reference for calculating taxable events and evaluating the performance of a portfolio over its lifecycle.
