Other factory costs

Insurance, setup, quality, and support costs.

Scrap recovery or factory credits

Credits that reduce net manufacturing cost.

Opening work in process value

Beginning partially completed production cost.

Closing work in process value

Ending partially completed production cost.

Opening finished goods value

Finished inventory at period start.

Closing finished goods value

Finished inventory remaining at period end.

Units produced

Completed units manufactured during the period.

Units sold

Units sold for gross profit estimation.

Selling price per unit

Used to estimate revenue and gross margin.

Planned manufacturing cost

Budget or standard cost for variance analysis.

Formula Used

Direct Labor Cost
Direct Labor Cost = Direct Labor Hours × Direct Labor Rate

Variable Overhead
Variable Overhead = Machine Hours × Variable Overhead Rate

Total Overhead
Total Overhead = Variable Overhead + Fixed Factory Overhead + Other Factory Costs − Scrap Recovery

Total Manufacturing Cost
Total Manufacturing Cost = Direct Materials + Direct Labor Cost + Total Overhead

Prime Cost
Prime Cost = Direct Materials + Direct Labor Cost

Conversion Cost
Conversion Cost = Direct Labor Cost + Total Overhead

Cost of Goods Manufactured
COGM = Opening Work in Process + Total Manufacturing Cost − Closing Work in Process

Cost of Goods Sold
COGS = Opening Finished Goods + COGM − Closing Finished Goods

Production Cost per Unit
Production Cost per Unit = COGM ÷ Units Produced

Gross Profit and Margin
Revenue = Units Sold × Selling Price per Unit
Gross Profit = Revenue − COGS
Gross Margin = (Gross Profit ÷ Revenue) × 100

Variance Against Plan
Variance Amount = Total Manufacturing Cost − Planned Manufacturing Cost

FAQs

1. What does this production cost calculator include?

It includes direct materials, direct labor, variable overhead, fixed overhead, other factory costs, work in process adjustments, finished goods adjustments, and optional budget variance.

2. What is the difference between total manufacturing cost and COGM?

Total manufacturing cost measures current-period factory spending. COGM adjusts that spending for opening and closing work in process to show the cost of completed goods.

3. Why are finished goods values included?

Finished goods balances are needed to move from goods manufactured to goods sold. That helps estimate cost of goods sold and gross profit.

4. What does variance against plan mean?

It compares actual manufacturing cost with the planned or budgeted cost. A negative variance means actual cost is below plan, which is usually favorable.

5. Can I use this calculator for job costing and process costing?

Yes. It works for both as a summary calculator. Enter the appropriate totals for the selected production period, batch, line, or job.

6. What should I enter for variable overhead rate?

Enter the variable factory cost assigned to one machine hour. Examples include utilities, indirect supplies, and other costs that change with production activity.

7. What happens if units produced are zero?

The calculator still computes total costs, but unit-based metrics become zero to avoid invalid division. Enter produced units for accurate unit cost analysis.

8. Can I download the results?

Yes. After calculation, you can export the report as CSV for spreadsheets or PDF for sharing, filing, and management review.
