What Is Bid Bond?
A bid bond is a type of surety bond that provides financial assurance to a project owner that a bidding contractor will honor its bid proposal. Falling under the broader financial category of surety bonds, which are contractual agreements involving three parties, a bid bond ensures that if a contractor submits the lowest bid for a project and is subsequently awarded the contract, they will proceed to enter into the contract and provide any required performance bond and payment bond. If the contractor fails to do so, the bid bond provides compensation to the project owner for damages incurred, typically to cover the cost difference of awarding the contract to the next lowest bidder.
History and Origin
The concept of bid bonds and other contract-related surety bonds has roots in the long history of commercial assurances. In the United States, the requirement for such bonds, particularly for federal projects, was formalized with significant legislation. One pivotal development was the enactment of the Miller Act in 1935. This federal statute mandated that general contractors on certain public works construction projects for the U.S. government furnish both a performance bond and a payment bond to protect the government and ensure subcontractors and suppliers are paid. While the Miller Act primarily addresses performance and payment bonds, it solidified the broader framework for contractual assurances, including the precedent for bid bonds in government contracting, which precede the final contract bonds. The Miller Act aimed to resolve procedural limitations of its predecessor, the Heard Act of 1894, by requiring separate bonds and providing clearer legal recourse6. Many states have since adopted similar "Little Miller Acts," extending these bonding requirements to state and local public works projects.
Key Takeaways
- A bid bond guarantees that a contractor will enter into a contract if their bid is accepted and provide other required bonds.
- It protects the project owner from financial losses if the winning bidder withdraws or fails to meet post-bid requirements.
- Bid bonds are typically a small percentage of the total bid amount, often 5% to 10%, though federal projects may require 20%.
- The bid bond process helps ensure that only qualified and serious contractors submit proposals.
- The three parties involved are the principal (contractor), the obligee (project owner), and the surety (the bond issuer).
Formula and Calculation
A bid bond does not involve a complex calculation in the way an investment return or a loan interest might. Instead, its value is typically a fixed percentage of the contractor's total bid amount for a project, or a specific stipulated sum.
The formula for the maximum liability of a bid bond is:
Where:
- Bid Percentage represents the agreed-upon percentage (e.g., 5%, 10%, or 20%) required by the project owner.
- Total Bid Amount is the overall price the contractor has quoted for the project.
For instance, if a project requires a 10% bid bond and a contractor submits a bid of $1,000,000, the bid bond's penal sum would be ( $1,000,000 \times 0.10 = $100,000 ). This is the maximum amount the surety would be liable for if the contractor defaults on their obligation to enter the contract. The actual cost to the contractor for obtaining the bid bond is usually a nominal fee or often free, as the main premium is charged for the subsequent performance and payment bonds.
Interpreting the Bid Bond
A bid bond serves as a critical pre-qualification tool in the competitive bidding process, particularly in the construction industry. When a contractor provides a bid bond, it signals to the obligee (project owner) that a reputable surety company has reviewed the contractor's qualifications and deemed them capable of undertaking the project and fulfilling the contractual obligations. This assessment often includes an examination of the contractor's financial statements, credit history, experience, and capacity for the project. The existence of a bid bond assures the project owner that if the contractor is awarded the bid, they have the backing to secure the necessary performance and payment bonds and ultimately complete the work for the quoted price. Without a bid bond, project owners would face greater uncertainty about a bidder's financial stability and commitment.
Hypothetical Example
Imagine "Apex Construction," a contractor, wants to bid on a new municipal library project. The city, as the obligee and project owner, requires all bidders to submit a bid bond equal to 5% of their total bid amount. Apex Construction calculates its bid for the library project to be $5,000,000.
To participate in the bidding process, Apex Construction approaches "SolidSurety," a surety company, to obtain the bid bond. SolidSurety conducts a thorough underwriting process, evaluating Apex Construction's financial health, experience, and past project successes. Once approved, SolidSurety issues a bid bond for $250,000 (5% of $5,000,000).
Apex Construction submits this bid bond along with its $5,000,000 proposal. The city reviews all bids and selects Apex Construction as the lowest responsible bidder. At this point, the bid bond ensures that Apex Construction will enter into the formal construction contract and provide the required performance and payment bonds for the project. If Apex Construction were to withdraw its bid or fail to provide the subsequent bonds, the city could claim on the $250,000 bid bond, which would then be used to offset any additional costs incurred, such as readvertising the project or awarding it to the next lowest bidder, potentially at a higher price.
Practical Applications
Bid bonds are widely used in sectors where competitive bidding for contracts is common, primarily in the construction industry. They are a standard requirement for government contracts at federal, state, and local levels, ensuring the integrity of the bidding process for public works projects5. For example, the U.S. Small Business Administration (SBA) offers a Surety Bond Guarantee Program to assist small businesses in obtaining various types of surety bonds, including bid bonds, which helps them compete for government contracts they might otherwise be unable to secure4.
Beyond public sector projects, bid bonds are also frequently mandated in large private construction and development projects. They offer a layer of risk management for the project owner, mitigating the risk of a winning contractor defaulting on their commitment after bid award. Organizations like the American Institute of Architects (AIA) provide standardized bid bond forms, such as AIA Document A310™, which are widely used in the industry to establish the terms of such agreements.

Limitations and Criticisms
While bid bonds offer significant protection to project owners, they do have certain limitations and potential criticisms. For the contractor, obtaining a bid bond requires a rigorous underwriting process by the surety, which can be time-consuming and require extensive documentation of the contractor's financial health and experience. This process can be a barrier for new or smaller businesses that may struggle to meet the strict criteria, even if they possess the technical capability to perform the work.
From the project owner's perspective, while a bid bond provides financial recourse, claims against bid bonds, though relatively rare, can occur if a contractor fails to enter into a contract after being awarded the bid. 2If a claim is made, the surety bond company will investigate its validity. If justified, the surety may pay the claimed amount to the obligee. However, the principal (contractor) remains ultimately liable to the surety for any losses paid out, as surety bonds are a form of credit, not insurance. 1This means the contractor must indemnify the surety, potentially leading to significant financial strain for the contractor if a claim is paid. This structure underscores that the bond is a guarantee rather than a coverage against the contractor's own financial shortfalls.
Bid Bond vs. Performance Bond
While both are types of surety bonds crucial in the construction industry, a bid bond and a performance bond serve distinct purposes at different stages of a project.
A bid bond is submitted at the bidding phase of a project. Its primary function is to assure the project owner that the contractor will sign the contract and furnish the required performance and payment bond if their bid is accepted. It safeguards the project owner from the costs incurred if the chosen bidder backs out after being awarded the contract, preventing delays and additional administrative expenses.
In contrast, a performance bond comes into play after the contract has been awarded and signed. It guarantees that the principal (contractor) will complete the project according to the terms and conditions of the contract, including quality, scope, and timeline. If the contractor fails to perform as agreed, the performance bond provides financial compensation to the project owner to cover the costs of completing the work or correcting deficiencies.
The key difference lies in timing and scope: a bid bond guarantees the intent to enter into a contract, while a performance bond guarantees the execution of the contract itself.
FAQs
What is the purpose of a bid bond?
A bid bond's main purpose is to assure a project owner that a contractor submitting a bid is serious and capable of entering into a contract and providing other necessary bonds if awarded the job. It protects the owner financially if the contractor fails to honor their bid.
Who are the parties involved in a bid bond?
There are three parties: the principal (the contractor submitting the bid), the obligee (the project owner requiring the bond), and the surety (the company that issues the bond and guarantees the principal's commitment).
Is a bid bond refundable?
A bid bond itself is not a deposit that is refunded. It is a guarantee. If the contractor is awarded the contract and fulfills their obligation to sign the contract and provide subsequent bonds (like a performance bond), the bid bond's obligation is released, and it effectively expires. If the contractor does not win the bid, the bond also expires without any financial penalty.
How much does a bid bond cost?
The cost of a bid bond to the contractor is usually very low, often a small flat fee or even free. Surety companies typically charge premiums for the larger performance bond and payment bond that are required once a contract is awarded, as these carry greater financial risk for the surety.
