To maximize profit, a firm in perfect competition must decide Marginal cost.
What is marginal cost?
The term "marginal cost" describes the rise in manufacturing costs brought on by the creation of more product units. A different name for it is the marginal cost of production. Businesses may evaluate how volume produced affects cost and eventually profits by calculating the marginal cost.
By dividing the increase in production expenses by the rise in unit output, marginal cost is obtained.
For instance, a business initially spends $100 to produce 100 product units. Then, it spends an additional $50 to produce 100 more units of the product. Each unit initially costs $1 to produce. However, the marginal cost ($50/100) is $0.50 per unit.
