A cost-plus contract is a type of agreement in which the contractor is reimbursed for all allowable costs incurred during a project, along with an additional payment to allow for a profit. This payment can be a fixed fee or a percentage of the costs. Cost-plus contracts are extensively used in industries such as construction, defense, and research and development.
Types of Cost-Plus Contracts
Cost-Plus Percentage of Cost
In a cost-plus percentage of cost contract, the contractor receives payment for all incurred costs plus an additional percentage as profit. This type of contract provides no incentive for the contractor to minimize costs, as higher costs result in higher profits.
Cost-Plus Fixed Fee
A cost-plus fixed fee contract specifies a fixed amount of profit regardless of total project costs. This model balances the need for covering costs with a fixed profit margin, incentivizing the contractor to manage costs efficiently.
Advantages and Disadvantages
Advantages
- Flexibility: Accommodates adjustments for complexity and unforeseen changes.
- Transparency: Clear visibility into incurred costs.
- Allocation of Risk: Risks related to unexpected costs are borne by the owner.
Disadvantages
- Cost Overruns: Potential for increased overall costs in percentage contracts.
- Complex Administration: Requires rigorous tracking and documentation of costs.
- Reduced Incentive for Cost Control: Especially in percentage contracts, there is less motivation to economize.
Historical Context
The cost-plus contract has its roots in the early 20th century, particularly becoming prominent during World War II, when expedited production was necessary, and precise cost estimation was challenging. It allowed companies to embark on large-scale projects with the assurance of covering costs plus a predictable profit margin.
Practical Examples
- Construction Projects: Frequently used for large-scale or complex construction projects where costs are difficult to estimate accurately.
- Defense Manufacturing: Employed in defense contracts where research, development, and production costs are variable and unpredictable.
- Research and Development: Suitable for R&D projects with uncertain outcomes and variable expenses.
Comparisons: Cost-Plus vs. Fixed-Price Contracts
| Aspect | Cost-Plus Contracts | Fixed-Price Contracts |
|---|---|---|
| Cost Predictability | Variable and uncertain | Fixed and predictable |
| Contractor Incentives | No strong incentives in percentage contracts | High incentive to complete under budget |
| Administrative Burden | High due to cost documentation | Lower compared to cost-plus |
Related Terms
- Fixed-Price Contract: A contract with a set price for the entire project, irrespective of the actual costs incurred.
- Time and Materials Contract: Payments are based on time spent and materials used, common in consultancy and service contracts.
