This method involves charging the client based on two main factors:
- Time Spent (Labor Costs):
- The hours worked by laborers or contractors, often billed at an hourly rate.
- Rates may vary depending on the worker’s skill level, such as apprentice, journeyman, or foreman.
- Typically includes a markup to cover overhead costs like insurance, benefits, and administrative expenses.
- Materials Used (Material Costs):
- The actual cost of materials needed for the project, including shipping and handling.
- A markup is usually added to the material costs to account for procurement efforts, storage, or as a profit margin.
Converting T&M to Price
To calculate a project’s final price based on the T&M method:
- Estimate Time:
- Calculate the hours required to complete the project based on past experience or project scope.
- Multiply the hours by the labor rate(s) to determine the labor cost.
- Estimate Materials:
- Identify all materials needed for the project.
- Add the cost of each material, including applicable taxes or shipping fees.
- Apply a markup to the material costs (e.g., 10-25% is common in many industries).
- Add Other Costs:
- Factor in any additional costs, such as equipment rentals, subcontractor fees, or permits.
- Include contingency for unforeseen issues (commonly 5-15%).
- Markup for Profit:
- Apply an overall markup to ensure profitability, particularly if time and material costs are only break-even rates.
- Total the Components:
- Add up labor, materials, additional costs, and profit to arrive at the final price.
Advantages of T&M Pricing
- Flexibility: Adjusts for changes in scope or unforeseen circumstances.
- Transparency: Clients see where their money is going.
- Accuracy: Aligns costs with the actual resources consumed.
Challenges of T&M Pricing
- Lack of Predictability: Clients may be wary of open-ended costs.
- Management Complexity: Requires detailed tracking of hours and material use.
- Potential Disputes: Miscommunication about rates or inefficiencies can lead to disagreements.
When to Use T&M to Price
- For projects where the scope is uncertain or likely to change.
- For tasks involving variable material use or labor intensity.
- When detailed documentation can justify costs to clients.
This pricing method often works well in service contracts, repairs, or unique construction projects but may not suit fixed-budget scenarios.
