Rent
Raw material
(b) Implicit Cost
Cost of using own resources (not paid in cash).
Also called opportunity cost.
👉 Example:

Salary of permanent staff
📌 Feature: Constant in total, decreases per unit when output increases.
(d) Variable Cost (VC)

More production = more cost.
👉 Examples:

Electricity
Packaging
(e) Total Cost (TC)
Total spending on production.
👉 Formula:
TC = FC + VC
🔹 3. Short Run Costs
Short run = some factors are fixed.
Types:
(a) Total Fixed Cost (TFC)
Remains constant.
(b) Total Variable Cost (TVC)
Increases with output.
(c) Total Cost (TC)
TC = TFC + TVC
