According to ES BuffaAccording to ES Buffa “Production is a “Production is a process by which goods and services are process by which goods and services are created.”created.”
In economicsIn economics “the term production means a “the term production means a process in which the resources are transferred or process in which the resources are transferred or converted in to a different and more usually converted in to a different and more usually commodities.”commodities.”

Actual cost
Actual cost is defined as the cost or expenditure which a firm incurs for producing or acquiring a good or service. The actual costs or expenditures are recorded in the books of accounts of a business unit. Actual costs are called as “Out lay Costs” or “Absolute Costs”
Eg. Cost of Raw material, wages, salaries (production)

Opportunity cost
opportunity cost is concerned with the cost of forgone opportunities/alternatives. In other words, it is the return from the second best use of the firms resources which the firm forgoes in order to avail of the return from the best use of the resources.

Sunk cost
Sunk costs are those do not alter by varying the nature or level of business activity. Sunk costs are generally not taken into consideration in decision making as they do not vary with the changes in the future. Sunk costs are a part of the outlay/actual costs. sunk costs areas “non-avoidable costs”. Or “non-escapable costs”.
Eg. All the past costs are considered as sunk costs. The best example is amortization of past expenses, like depreciation

Historical cost & Replacement cost
Historical cost (Original cost) of an asset refers to the original price paid by the management to purchase it in the past. Whereas the Replacement cost refers to the cost that a firm incurs to replace or acquire the same asset now.
The distinction between the historical cost and the replacement cost result from the changes of prices over time.
Eg. If a firm acquires a machine for rs.20,000 in the year 1990 and the same machine cost of rs.40,000 now. The amount of rs.20,000 is the historical cost and the amount of rs.40,000 is the replacement cost.

Advantages of BEPAdvantages of BEP
To achieve a given amount of profit the break even analysis can be
used to determine the sales volume.
It can be used to forecast the future cost and revenue and it can
predict the profit.
To control the cost in business the cost functions used in break
even analysis can be useful.
The break even analysis useful for profit planning in business.
The break even analysis can be useful in sales projection.
