How to Use the Calculator

To use this Cost Basis Calculator, enter the number of shares you have purchased and the purchase price per share. Then click on the “Calculate” button to see your total cost basis.

How It Calculates

The calculator multiplies the number of shares by the purchase price per share to yield the total cost basis of the investment. The formula used is:

Cost Basis = Number of Shares * Purchase Price per Share


Note that this calculator assumes a single purchase price for all shares and does not take into account multiple purchasing prices, commissions, or additional costs related to buying the shares. It also does not provide tax advice or account for inflation, dividend reinvestment, or capital gains.
