IRB Review Costs: What to Budget

Understanding IRB review costs helps you plan more accurately and avoid budget surprises. This guide breaks down the key factors that influence IRB fees so you can approach your next study with confidence. 

What Affects IRB Review Costs? 

IRB review fees tend to vary based on several study-specific factors including the complexity, scope, and type of review your protocol requires. At WCG, we charge a single flat rate for protocol review as well as other actions with pricing dependent on factors such as the number of sites. For more information, get in touch with one of our IRB experts below. 

Type of Review Required 

Not all studies undergo the same level of scrutiny. Studies qualifying for expedited or exempt review are generally less costly than those requiring full-board review; however, WCG applies the same protocol fee for exempt, expedited, or full board review. The nature of your research and the risks involved for participants determine which category applies.

Protocol Complexity 

More complex protocols — those involving multiple procedures, vulnerable populations, or investigational devices — typically require more thorough evaluation. Greater review time and resources can translate to higher fees depending on the IRB provider. 

Number of Sites 

Multi-site studies require coordination across institutions. If your study spans several research sites, you can expect costs to reflect the additional administrative and review work involved. 

Amendments and Continuing Reviews 

IRB review doesn’t end at initial approval. Protocol amendments, continuing reviews, and safety monitoring submissions each carry their own associated fees. It can be difficult to predict the correct budgetary needs due to these factors. Early alignment with an IRB expert like WCG can help provide some insight on what to expect. 

Sponsor and Institution Type 

Fee structures may differ depending on whether you are a commercial sponsor, an academic institution, or a non-profit organization. Some IRBs offer tiered pricing to accommodate different organization types. WCG charges a flat fee per protocol and offers WCG’s IRB+ for studies that need an extra level of attention and white-glove service to ensure accelerated processing times without sacrificing quality or integrity.

How Much Does IRB Review Cost? 

IRB review costs vary widely. Initial full-board review fees for a commercial study can range significantly, depending on various factors. Expedited reviews tend to be more affordable. Continuing reviews and amendments are typically priced lower than initial submissions. 

Because every study is different, the most reliable way to understand what your specific protocol will cost is to request a formal fee schedule from your IRB provider. For information about WCG’s IRB services and pricing, get in touch with one of our IRB experts below. 

Why Budget Accurately from the Start? 

Underestimating IRB costs is a common source of budget overruns in clinical research. Accounting for the full scope of review-related expenses — initial review, amendments, continuing reviews, and any site additions — gives your study a more stable financial foundation. 

Working with an experienced IRB partner also means you benefit from predictable turnaround times and streamlined workflows, which can reduce indirect costs associated with delays. 

WCG has served as the trusted IRB review partner for the development of 94 percent of all Food and Drug Administration (FDA)-approved therapeutic agents in the last five years. Our average full-board review determinations arrive 20 percent ahead of targeted turnaround times, helping you protect timelines and control costs. 

Frequently Asked Questions 

How much does IRB review cost? 

IRB review costs depend on the type of review, protocol complexity, number of sites, and sponsor type. Full-board reviews for commercial studies can range significantly depending on multiple factors. Expedited and exempt reviews are typically less expensive. At WCG, we charge a single flat rate for protocol review as well as other actions with pricing dependent on factors such as the number of sites. To get accurate pricing for your study, request a fee schedule directly from your IRB. 

What is included in an IRB review fee? 

Fees generally cover the administrative processing and ethical review of your protocol. Depending on your IRB, additional services such as regulatory consulting, document review, and continuing review may be included or priced separately. 

Are IRB fees negotiable? 

Some IRBs offer pricing tiers based on organization type, study phase, or volume of submissions. It’s worth discussing your situation directly with your IRB provider to understand what options are available. 

Do I pay separate fees for each study site? 

In many cases, yes. Multi-site studies involve additional coordination and review, which is reflected in the fee structure. Your IRB should be able to provide a clear breakdown of per-site costs when you request a fee schedule. 

When should I budget for IRB costs? 

IRB costs should be incorporated into your study budget from the earliest planning stages. Account for initial review, anticipated amendments, continuing reviews, and any site additions to avoid gaps in your financial planning.
