3C's that determine price of products are Cost, Customer and Competition.
Understanding cost
and revenue in economic term:
Price of a product must exceed per unit production and non-production
costs. Per unit cost of product can be expressed in two ways. Average cost and
Marginal cost. Average cost is per unit cost derived by dividing total costs by
total unit of production. Organisation will break even for unit sales price
equal to unit cost of production. Any drop in sales price will create loss.
Marginal cost is the extra cost incurred for production and sales of one more
unit of product. Where marginal cost is less than sales price, organisation
will maximize profit. Marginal cost greater than sales price does not always
mean a loss. Before creating any loss, increased marginal cost minimizes profit
to zero. Money collection for the exchange of product/service is termed as
revenue. In mathematical terms, sales price per unit multiplied by sales for
the period is called (total) revenue. Sales price per unit is also called
average revenue. Marginal revenue on the other hand is the sales revenue
generated form one extra product. The table below shows effect on average cost,
average revenue, marginal cost and marginal revenue for change in production
level.
Example: For a monopoly firm: where facility can produce
maximum of 7 units per period.
