Key Takeaways

  • A cost plus incentive fee contract (CPIF) reimburses contractors for costs and provides additional fees tied to performance, such as cost savings or efficiency.
  • These contracts balance risk between owners and contractors by rewarding cost control while covering actual expenses.
  • Essential elements include target cost, base fee, incentive fee formula, and minimum/maximum limits.
  • They are most useful when project scope is uncertain but cost-efficiency is critical.
  • CPIF contracts differ from cost plus fixed fee contracts, which do not offer performance-based incentives.
  • Advantages include motivating efficiency and sharing risk, while disadvantages include administrative complexity and potential disputes over cost calculations.

A cost plus incentive fee contract is a special type of fixed-price contract that provides contractors and sellers with additional financial incentives for keeping the cost of the project as low as they can. A contract of this nature may also offer incentives when the seller meets other criteria that are laid out in the contract agreement before work begins.

Cost Plus Incentive

Cost plus incentive fees are reimbursement methods that are built into certain fixed-price contracts, specifically the cost plus incentive fee contract. These provide contractors with special incentives to keep the cost of a project under certain thresholds. A cost plus incentive fee contract provides a way to apply any savings, whether financial or by completing work ahead of schedule, that the contractor is able to secure to the pay that he or she will receive for the contracted work.

How Cost Plus Incentive Fee Contracts Work

A cost plus incentive fee contract works by setting a target cost and a target fee, then adjusting the contractor’s compensation based on actual performance. If the project is completed under budget, the contractor earns additional fees, usually calculated through a pre-negotiated sharing formula (e.g., a 60/40 split of cost savings between client and contractor). If the project exceeds the target cost, the contractor’s fee may be reduced proportionally.

This incentive structure motivates contractors to manage costs effectively while ensuring they are reimbursed for allowable expenses. In practice, CPIF contracts are often used in government procurement, research and development, and construction projects where costs are difficult to predict but performance efficiency is essential

What Should a Cost Plus Incentive Fee Contract Include?

Contracts of this nature include incentives that are negotiated and agreed upon ahead of time. The incentive fee comes into play when the actual cost of the project comes in below the originally agreed upon cost in the contract. A cost plus incentive fee contract should include the following components:  

Additional items that should be covered in the contract include:  

  • Target fees  
  • Minimum fees  
  • Maximum fees  
  • A method to calculate fee adjustments.

Once a project has been completed, the fee the contractor is entitled to receive should be calculated using the methods built into the contract. Cost plus incentive fee contracts are used in an attempt to share the financial risk of a project between the project's owner and the contractor.

Contracts of this nature can be considered a hybrid between the firm fixed price and cost plus contract types. These contracts utilize special theories to lay out how the project owner and the contractor will determine the best way to divide this risk. This is based on each party's respective point of view.

Advantages and Disadvantages of CPIF Contracts

Like all contract types, a cost plus incentive fee contract has benefits and drawbacks:

Advantages:

  • Encourages contractors to control costs and improve efficiency.
  • Shares financial risk between owner and contractor.
  • Offers flexibility for projects with uncertain or evolving requirements.
  • Can result in higher quality outcomes since contractors are not pressured to cut corners to meet a fixed price.

Disadvantages:

  • Administrative complexity in tracking costs and calculating incentive adjustments.
  • Potential disputes over what costs are allowable or how savings are shared.
  • Less cost certainty for owners compared to firm fixed-price contracts.
  • Contractors may still lack motivation to minimize costs if reimbursement processes are too lenient.

Negotiating the Terms of a Cost Plus Incentive Fee Contract

During the negotiation phase of the contract, both parties will have the opportunity to discuss their point of view and reach an agreement that is optimal for everybody involved. This formula allows for fee increases that can potentially exceed the target fee within reason. However, this should only be allowed when actual costs are below the target costs. 

Additionally, the contract should allow for decreases in the target fee if actual costs rise above the target cost laid out in the contract. These potential fluctuations are built into the contract as a method for providing the contractor with additional incentives to manage the project as efficiently as possible.

When the total actual cost is higher or lower than the total target cost laid out in the contract, the contractor will be paid the total allowable cost with one of two possible adjustments, based on the specific situation:  

  • Minimum incentive fee is applied if total actual costs are higher than the total target cost.  
  • Maximum incentive fee is applied if total actual costs are lower than the total target cost.

When to Use a Cost Plus Incentive Fee Contract

This contract type is particularly useful when:

  • The project involves innovative or experimental work, such as R&D or new technology development.
  • Costs are difficult to estimate accurately at the outset.
  • The owner wants to encourage contractors to achieve cost efficiency and timely performance without bearing all the risk.
  • There is a need for shared accountability, where both parties contribute to controlling expenses.

For example, government defense agencies often use CPIF contracts to ensure that contractors are motivated to deliver projects efficiently while still accommodating evolving technical requirements

Cost Plus Fixed Fee

In a cost plus fixed fee contract, the fee that was agreed upon during contract negotiations remains the same. This is regardless of the actual total cost of the project upon completion. However, if the project's scope changes, this contract does allow for adjustments to be made to the fee. The contractor must submit a separate set of invoices to be reimbursed for the cost of things, such as labor and materials.

A cost plus fixed fee contract is typically used when the costs of a project are hard to estimate. This could possibly create a potential financial risk for contractors vying for a winning bid on the project. Contracts of this nature are primarily awarded based on the contractor's proposed fees. It is important to note that cost plus fixed fee contracts don't provide any form of incentives for contractors to manage the costs associated with the project effectively.

A cost plus incentive fee contract should never be awarded to a contractor unless all the limitations outlined in 16.301-3 are fully and completely complied with.

Cost Plus Incentive Fee vs. Cost Plus Award Fee

While both CPIF and cost plus award fee (CPAF) contracts are designed to motivate contractors, they operate differently:

  • Cost Plus Incentive Fee (CPIF): The incentive is tied to quantifiable measures, such as cost savings or efficiency. The contractor’s fee is adjusted based on a clear formula comparing actual costs to target costs.
  • Cost Plus Award Fee (CPAF): The incentive depends on the client’s subjective evaluation of contractor performance, such as quality, timeliness, and overall satisfaction.

The key distinction is that CPIF relies on measurable cost outcomes, while CPAF rewards broader, often subjective, performance factors.

Frequently Asked Questions

1. What is a cost plus incentive fee contract?

It is a contract where the contractor is reimbursed for costs and paid an additional incentive fee based on meeting or beating cost and performance targets.

2. How is the incentive calculated in a CPIF contract?

The incentive is determined using a formula agreed upon in advance, typically involving a sharing ratio that splits cost savings or overruns between the client and contractor.

3. When should a CPIF contract be used?

It is best suited for projects with uncertain costs, such as research, defense, or technology development, where both parties want to share risk and encourage efficiency.

4. What are the risks of a CPIF contract?

Risks include complex administration, potential disputes over allowable costs, and less cost predictability compared to fixed-price contracts.

5. How does CPIF differ from CPAF?

CPIF ties contractor incentives to measurable cost outcomes, while CPAF links incentives to subjective performance evaluations by the client.
