Stock Profit Calculator

Frequently Asked Questions

How is stock profit calculated?

Stock profit is calculated using the following formula:

  • Total Cost Basis = (Shares x Buy Price) + Buy Commission
  • Total Proceeds = (Shares x Sell Price) - Sell Commission
  • Net Profit/Loss = Total Proceeds - Total Cost Basis
  • Percentage Return = (Net Profit/Loss / Total Cost Basis) x 100
What is annualized return?

Annualized return shows your investment performance as a yearly rate:

  • Converts total return to an equivalent annual rate
  • Useful for comparing investments held for different periods
  • Accounts for compound growth over time
  • Formula: ((1 + Total Return)^(1/Years) - 1) x 100
Should I include trading commissions?

Including commissions gives you the true net profit:

  • Many brokers now offer commission-free trading
  • Traditional brokers may charge per-trade fees
  • Commissions reduce your actual profit
  • Enter 0 if your broker offers free trades
What is the difference between profit and return?

Profit and return measure gains differently:

  • Profit is the dollar amount gained or lost
  • Return is the percentage gain or loss
  • Return helps compare different sized investments
  • Both are important for evaluating investment performance
