1. What Is Cost Basis?

Cost Basis represents the original investment cost of an asset for capital gains tax purposes. It includes the purchase price plus any adjustments such as fees, commissions, and reinvested dividends.

2. How Does The Calculator Work?

The calculator uses the Cost Basis formula:

\[ \text{Cost Basis} = \text{Purchase Price} + \text{Adjustments (fees, dividends)} \]

Where:

\( \text{Purchase Price} \) — Original price paid for the asset
\( \text{Adjustments} \) — Additional costs like brokerage fees, commissions, reinvested dividends
