📈 Average Fixed Cost Calculator
Calculate fixed cost per unit produced
Total fixed costs (rent, salaries, insurance, etc.)
Number of units produced
How to Use This Calculator
Enter Total Fixed Costs
Input the total fixed costs for your production period. These are costs that don't change with production volume (rent, salaries, insurance, etc.).
Enter Units Produced
Input the number of units produced during the same period. This can be any unit of measurement (pieces, hours, services, etc.).
Calculate

Review Results
Use the results for pricing decisions, cost analysis, and understanding how fixed costs are allocated across production.
Formula
Average Fixed Cost (AFC):
AFC = Total Fixed Costs / Units Produced
Average fixed cost decreases as production increases because fixed costs are spread over more units.
Example 1: Low Production
Total Fixed Costs: $10,000, Units Produced: 500
Average Fixed Cost: $10,000 / 500 = $20.00 per unit
Fixed costs are spread over 500 units, resulting in $20 per unit.
Example 2: High Production
Total Fixed Costs: $10,000, Units Produced: 5,000
Average Fixed Cost: $10,000 / 5,000 = $2.00 per unit
The same fixed costs spread over 5,000 units result in only $2 per unit - a 90% reduction!
Example 3: Service Business
Total Fixed Costs: $50,000 (monthly), Services Provided: 200
Average Fixed Cost: $50,000 / 200 = $250.00 per service
Each service carries $250 in fixed costs, which must be covered by pricing.

Frequently Asked Questions
What are fixed costs?
Fixed costs are expenses that don't change with production volume. Examples include rent, salaries, insurance, depreciation, and property taxes. They remain constant regardless of how much you produce.
Why does average fixed cost decrease with production?
Average fixed cost decreases because you're spreading the same total fixed costs over more units. If fixed costs are $10,000 and you produce 100 units, it's $100 per unit. If you produce 1,000 units, it's only $10 per unit.
Should I use units produced or units sold?
Use units produced for cost accounting purposes. Units sold is relevant for revenue analysis, but for cost allocation, you want to know the cost per unit produced.
What if my fixed costs change during the period?
Use the total fixed costs for the period. If costs changed mid-period, you can calculate separate averages for each sub-period or use a weighted average.
How is this different from average variable cost?
Average fixed cost decreases as production increases. Average variable cost typically stays constant or may increase slightly due to efficiency gains or overtime. Total cost per unit combines both.
Can average fixed cost ever be zero?
No, as long as you have fixed costs and produce at least one unit, average fixed cost will be positive. However, as production approaches infinity, average fixed cost approaches zero (but never reaches it).
