How to use this calculator

Enter fixed costs, variable cost per unit, units sold, and miscellaneous costs. The calculator estimates total cost, cost per unit, and efficiency status.

What the result means

Total cost shows how much money your business must spend to operate at a given volume. Unit cost helps with pricing, break-even planning, and margin analysis.

Total Cost = Fixed Costs + (Variable Cost per Unit x Units Sold) + Miscellaneous Costs. Unit Cost = Total Cost / Units Sold.

For better pricing decisions, compare unit cost with your selling price and target margin.

Example calculation

If fixed costs are $5,000, variable cost is $10 per unit, units sold are 1,000, and misc costs are $2,000, total cost is $17,000 and unit cost is $17.

Tips for better results

  • Separate fixed costs from variable costs.
  • Negotiate supplier pricing as volume grows.
  • Use unit cost before setting product prices.
