About Cost Functions
What are Cost Functions?
Cost functions represent the relationship between production quantity and total cost. They are fundamental in economics and business for understanding production efficiency, pricing strategies, and optimal output levels. Cost functions help businesses make informed decisions about production scale and resource allocation.
Types of Cost Functions
Linear Cost
C(q) = FC + VC × q
Constant marginal cost. Common in simple manufacturing with fixed per-unit costs.
Quadratic Cost
C(q) = FC + bq + cq²
Increasing marginal cost. Reflects capacity constraints and diminishing returns.
Power Cost
C(q) = FC + aq^b
Economies or diseconomies of scale depending on exponent value.
Key Cost Concepts
- Fixed Cost (FC): Costs that don't vary with production quantity
- Variable Cost (VC): Costs that change with production quantity
- Marginal Cost (MC): Additional cost of producing one more unit
- Average Cost (AC): Total cost divided by quantity produced
- Economies of Scale: Decreasing average cost as production increases
- Diseconomies of Scale: Increasing average cost as production increases

Example Scenarios
Try These Examples:
- Linear: FC=1000, VC=50 (simple manufacturing)
- Quadratic: FC=1000, b=30, c=2 (capacity constraints)
- Power: FC=1000, a=50, b=0.8 (economies of scale)
- Custom: 500 + 25*q + 0.5*q^2 + 0.01*q^3 (complex production)
