Total Manufacturing Cost for the Period Formula
The Total Manufacturing Cost (TMC) is the sum of the three primary costs incurred during the production process in a given period.
TMC = Direct Materials Used + Direct Labor + Manufacturing Overhead
TMC = DM + DL + MOH

Variables Explained
The calculation requires three core inputs, representing all costs that convert raw materials into finished goods:
- Direct Materials Used (DM): The cost of raw materials that become an integral part of the finished product and can be directly traced to it (e.g., wood for a chair, microchips for a computer).
- Direct Labor (DL): The wages paid to employees who physically work on converting the materials into the finished product (e.g., assembly line workers).
- Manufacturing Overhead (MOH): All other manufacturing costs that are neither direct materials nor direct labor, such as factory utilities, depreciation on equipment, and factory maintenance.

What is Total Manufacturing Cost for the Period?
The Total Manufacturing Cost (TMC) for the Period is a critical accounting figure that captures the collective cost of all resources consumed by the production process during a defined timeframe. It is the summation of direct materials, direct labor, and manufacturing overhead.
Understanding TMC allows management to monitor efficiency, control costs, and make informed pricing decisions. It is the necessary starting point for determining the Cost of Goods Manufactured (COGM), which subsequently leads to the Cost of Goods Sold (COGS).
In essence, TMC represents the total ‘input’ cost before accounting for the value of work-in-process (WIP) inventory, providing a clean measure of the period’s production expenditure.
How to Calculate Total Manufacturing Cost (Example)
Imagine “Alpha Motors” is producing electric scooters for the month of November:
- Determine Direct Materials Used (DM): Alpha Motors calculated that the total cost of aluminum, batteries, and tires put into production was $750,000.
- Determine Direct Labor (DL): The wages and benefits for all assembly workers totaled $400,000.
- Determine Manufacturing Overhead (MOH): Factory rent, utilities, depreciation, and supervisor salaries came to $210,000.
- Calculate TMC: Sum the three costs: $750,000 (DM) + $400,000 (DL) + $210,000 (MOH) = $1,360,000.
Frequently Asked Questions (FAQ)
What is the difference between TMC and COGM?
TMC (Total Manufacturing Cost) is the total cost added to production during the period. COGM (Cost of Goods Manufactured) is TMC *plus* the beginning Work-in-Process (WIP) inventory *minus* the ending WIP inventory. COGM represents the cost of goods actually *completed* during the period.
Does TMC include non-manufacturing costs like Sales or Admin?
No. TMC is strictly limited to costs incurred in the factory or production process (product costs). Selling and administrative expenses (period costs) are recorded separately on the income statement.
Why is it important to track TMC?
Tracking TMC is vital for inventory valuation (per GAAP), budgeting, variance analysis, and managerial decision-making. A sudden increase in TMC can signal rising material costs, labor inefficiency, or higher overhead rates.
What is Direct Materials Used vs. Direct Materials Purchased?
Direct Materials Purchased is the cost of materials bought during the period. Direct Materials Used is the cost of materials actually *consumed* by the production process, calculated as: Beginning Raw Materials Inventory + Purchases – Ending Raw Materials Inventory.
