What is Cost Plus Contract?

A cost plus contract is a type of construction contract in which the builder is paid for all actual costs incurred plus an agreed-upon fee. This fee is generally a percentage of the total costs and is intended to cover the builder’s overhead and profit.

Cost plus contracts are often used when the scope of work is not well defined or when there is a need for flexibility during construction. They are also commonly used for public works projects, where the winning bidder is typically selected based on their proposed fee.

One advantage of cost plus contracts is that they can provide financial certainty for the builder. However, they can also lead to cost overruns if the builder underestimates their costs or if the scope of work expands during construction.

How Cost Plus Contracts Differ from Fixed-Price Contracts

A Cost Plus Contract, also known as a Cost-Reimbursement Contract, is a type of contract where the buyer agrees to reimburse the seller for all costs incurred during the project, plus an agreed-upon fee. This type of contract is often used when the seller is unable to estimate the cost of the project accurately.

A Fixed-Price Contract, on the other hand, is a type of contract where the price is fixed and does not change, no matter how much the project costs. This type of contract is often used when the buyer and seller have a good understanding of the project scope and can agree on a price up front.

The Pros and Cons of Cost Plus Contracts

There are a few key advantages and disadvantages to cost plus contracts that are important to consider before signing one. Pros of a cost plus contract include the fact that all costs incurred by the contractor are covered, so there is no risk of going over budget. In addition, these types of contracts often have built-in incentives for the contractor to complete the project quickly and efficiently. Cons of cost plus contracts can include the fact that they can sometimes lead to contractors cutting corners in order to save on costs. Additionally, these types of contracts can be difficult to monitor and may give the contractor too much leeway in terms of pricing.

A cost plus contract is simply an agreement between a buyer and seller in which the seller agrees to reimburse the buyer for all costs incurred in the production of a product or service, plus an additional fee for their services.

This type of contract can be advantageous for both parties involved, as it allows the buyer to control costs and ensures that they are getting what they pay for. In order to negotiate a cost plus contract, it is important to keep the following points in mind:

1. Make sure that you have a clear understanding of what is included in the contract. The last thing you want is any surprises down the line.

What to Include in a Cost Plus Contract

In a cost plus contract, the contractor is reimbursed for their actual costs plus a fee. This fee is typically a percentage of the total costs and is used to cover the contractor’s overhead and profit. The advantage of this type of contract is that it gives the contractor an incentive to keep costs low. The disadvantage is that it can lead to disputes over what should be included in the final bill.

To avoid problems, it is important to clearly define what costs will be covered by the contract. This should include all materials, labor, equipment, permits, and any other necessary expenses. The contract should also specify how the fee will be calculated and paid. Both parties should agree on these terms before work begins.


In conclusion, cost plus contracts are an attractive and beneficial form of agreement for both parties involved. The contractor is able to ensure they are reimbursed for all associated costs while the client maintains a certain level of control over the costs incurred throughout the project. Cost plus contracts can be used in many different industries and adapted to specific needs that arise during construction or other projects. With this knowledge, companies will be better equipped to decide if this type of contract is right for their organization.
