How to use this calculator
- Enter fixed production cost, total variable production cost, produced units.
- Choose a display currency, then select Calculate. Results also update after a brief pause while you edit.
- Read the result with the assumptions below. Export details or save a second scenario to compare your choices.
Formula and method
AFC=fixed cost/units; AVC=variable cost/units; ATC=(fixed+variable)/units.
Assumptions and limitations
Costs must use the same production scope and period; average cost is not marginal cost.
Worked example
With fixed production cost = 10000, total variable production cost = 20000, produced units = 1000, average fixed cost is approximately 10.
What the result means
Separate fixed and variable cost per produced unit for one output level.
Common questions
How should I interpret average fixed cost?
Separate fixed and variable cost per produced unit for one output level.
What should I check before using this result?
Costs must use the same production scope and period; average cost is not marginal cost.
