Worked out from U.S. Securities and Exchange Commission - Cost Basis for Securities Transactions and 1 other source.
Profit is before tax. Capital-gains treatment depends on your holding period and jurisdiction.

How this is worked out

5 steps
  1. Cost basis = 10 shares x 1 x 5 = 50
  2. Gross proceeds = 10 x 1 x 7 = 70
  3. Fees = 0 + 0 = 0
  4. Profit = 70 - 50 - 0 = 20
  5. Break-even sell price = (50 + 0) / 10 = 5
