CISCE: Class 12
Introduction
Theories of costs help us understand how businesses plan their spending when making products.
CISCE: Class 12
Types of Cost Theories
- Traditional Theory
Focuses on two time periods: short run (some things can't be changed quickly) and long run (everything can be changed). - Modern Theory
CISCE: Class 12
Types of Production Cost
| Cost Type | Simple Definition | Example (Sandwich Shop) |
|---|---|---|
| Total Cost | Total money spent to make something | All costs to make 50 sandwiches/day |
| Average Cost | Cost per item produced | ₹500 for 50 sandwiches → ₹10 each |
| Marginal Cost | Extra cost for making one more item | ₹10 extra to make the 51st sandwich |
CISCE: Class 12
Real-Life Application
A sandwich shop spends ₹500 each day. Making the 51st sandwich costs an extra ₹10. This shows the difference between total, average, and marginal costs.
CISCE: Class 12
Key Points: Theories of Costs: Traditional Theory of Costs/Short Run Cost Curves
- There are two main cost theories: traditional and modern.
- The three main types of cost in production are total cost, average cost, and marginal cost.
- Marginal cost helps businesses decide if it is worth making more items.
