Continuous compounding is the mathematical limit that compound interest can reach if it's calculated and reinvested into an account's balance over a theoretically infinite number of periods. While this is not possible in practice, the concept of continuously compounded interest is important in finance. It is an extreme case of compounding, as most interest is compounded on a monthly, quarterly or semiannual basis.
Economic profit is the difference between total monetary revenue and total costs, but total costs include both explicit and implicit costs. Economic profit includes the opportunity costs associated with production and is therefore lower than accounting profit. Economic profit also accounts for a longer span of time than accounting profit. Economists often consider long-term economic profit to decide if a firm should enter or exit a market.
The cash flow statement provides data for ratios dealing with cash. For example, the payout ratio is the percentage of net income paid out to investors. Both dividends and share repurchases are considered outlays of cash and can be found on the cash flow statement. For example, if dividends are $100,000, share repurchases are $100,000, and income is $400,000, the payout ratio is calculated by dividing $200,000 by $400,000, which is 50%.
In the short run, a firm can make an economic profit. However, if there is economic profit, other firms will want to enter the market. If the market has no barriers to entry, new firms will enter, increase the supply of the commodity, and decrease the price. This decrease in price leads to a decrease in the firm’s revenue, so in the long-run, economic profit is zero. An economic profit of zero is also known as a normal profit. Despite earning an economic profit of zero, the firm may still be earning a positive accounting profit.
