Marginal Cost Calculator
Calculate the cost of producing one additional unit of output for business decision making
Calculate Marginal Cost
The difference between new total cost and previous total cost
The difference between new quantity and previous quantity
Marginal Cost Results
Formula used: MC = ΔTC ÷ ΔQ
Calculation: $0.00 ÷ 0 units = $0.00
Production Decision Analysis
Example Calculation
Chair Manufacturing Example
Initial Production: 10,000 chairs
Initial Total Cost: $5,000
New Production: 12,000 chairs
New Total Cost: $5,500
Change in Cost: $500
Change in Quantity: 2,000 chairs
Calculation
MC = ΔTC ÷ ΔQ
MC = $500 ÷ 2,000
MC = $0.25 per chair
Each additional chair costs $0.25 to produce
Key Cost Concepts
Marginal Cost
Cost of producing one additional unit
Fixed Cost
Costs that don't change with output
Variable Cost
Costs that change with output level
Total Cost
Fixed cost + Variable cost
Production Tips
Compare marginal cost with marginal revenue
Lower marginal costs indicate economies of scale
Rising marginal costs suggest production limits
Use for optimal production level decisions
Understanding Marginal Cost
What is Marginal Cost?
Marginal cost is the additional cost incurred when producing one more unit of a good or service. It's a fundamental concept in economics and business that helps companies make optimal production decisions.
Why is it Important?
- •Determines optimal production quantity
- •Helps set competitive pricing strategies
- •Identifies economies and diseconomies of scale
- •Supports make-or-buy decisions
Formula Explanation
MC = ΔTC ÷ ΔQ
- MC: Marginal Cost
- ΔTC: Change in Total Cost
- ΔQ: Change in Quantity
Decision Rule: Continue production as long as marginal cost is less than or equal to marginal revenue (MC ≤ MR)
Marginal Cost Behavior
Decreasing MC
Indicates economies of scale. Fixed costs are spread over more units, reducing per-unit costs.
Constant MC
Suggests efficient production at current scale. Each additional unit costs the same to produce.
Increasing MC
Indicates diseconomies of scale. Production constraints may be causing higher per-unit costs.
