gross profit-expenses=net profit

Pure economic profit is the increase in wealth that an investor has from making an investment, taking into consideration all costs associated with that investment including the opportunity cost of capital. Accounting profit is the difference between retail sales price and the costs of acquisition (whether by harvest, extraction, manufacture, or purchase). A key difficulty in measuring either definition of profit is in defining costs. Accounting profit may be positive even in competitive equilibrium when pure economic profits are zero.

There is no picture of profit.
