SOC 2 Audit Cost: What You Should Budget and Why
The SOC 2 audit cost for a first engagement typically runs between $15,000 and $100,000, depending on whether you are pursuing a Type 1 or Type 2 report, the number of Trust Services Criteria in scope, your organization’s size and control maturity, and the tier of CPA firm you select. A SOC 2 Type 1 audit generally takes 6 to 12 weeks from kickoff to final report, while a Type 2 audit runs 6 to 12 months when you include the observation period. Understanding what drives these numbers before you go to market for a firm will help you scope the engagement correctly and avoid scope creep surprises.
What the SOC 2 Framework Actually Is
SOC 2 is an attestation standard governed by the American Institute of Certified Public Accountants (AICPA) under SSAE 18, the Statement on Standards for Attestation Engagements No. 18. Only a licensed CPA firm can issue a SOC 2 report. The examination measures whether a service organization’s controls meet the AICPA’s Trust Services Criteria (TSC), which are organized into five categories: Security, Availability, Processing Integrity, Confidentiality, and Privacy.
Security is required in every SOC 2 engagement. The other four categories are optional and depend on the commitments the service organization makes to its customers. Adding categories expands audit scope and therefore increases cost. A company that processes healthcare records may scope in Privacy and Confidentiality; a SaaS platform with uptime SLAs may add Availability. Each category you include adds control populations to test, and auditor hours to the bill.
For a deeper look at the framework itself, see our guide on what a SOC 2 audit is and what to expect.
SOC 2 Audit Cost by Report Type
The single biggest cost driver is whether you need a Type 1 or Type 2 report. The two are not interchangeable, and most enterprise buyers require Type 2.
Type 1: Design at a Point in Time
A Type 1 report evaluates whether your controls are suitably designed as of a single date. It does not test operating effectiveness over time. Because the auditor is not gathering a full evidence population across months of transactions, fieldwork is shorter and the fee is lower.
Typical Type 1 audit fees at specialist or regional CPA firms run $10,000 to $30,000. Mid-tier national firms quote $20,000 to $60,000 for the same scope. The Big Four can reach $60,000 to $140,000 for a Type 1, largely because of brand and overhead, not incremental complexity.
A Type 1 is most useful early in a compliance program when a prospect asks for some assurance before you have completed a full observation period. Treat it as a stepping stone, not a destination. For more on which report type to pursue first, see SOC 2 Type 1 vs Type 2: Where to Start.
Type 2: Operating Effectiveness Over Time
A Type 2 report tests whether controls operated effectively across a defined observation period, most commonly 6 or 12 months. It provides substantially stronger assurance and is what enterprise procurement, regulated-industry buyers, and most security questionnaires actually require.
Type 2 fees run higher because auditors sample evidence across the entire period, meaning far more testing procedures and evidence requests. Typical ranges:
- Specialist and boutique CPA firms: $15,500 to $50,000
- Regional CPA firms: $20,000 to $95,000
- Mid-tier national firms (RSM, BDO, Grant Thornton tier): $30,000 to $120,000
- Big Four: $60,000 to $450,000
For a first-year Type 2 engagement at a mid-market company, budget $30,000 to $100,000 as a working baseline. Annual renewal audits typically run 75 to 90 percent of the initial fee, since policy drafting and readiness work are largely one-time costs.
Beyond the Audit Fee: What Else Goes Into the Cost of a SOC 2 Audit
The audit fee is only part of the total investment. First-year SOC 2 programs carry several additional cost layers.
Readiness Assessment
Before fieldwork begins, most companies commission a readiness assessment to identify control gaps against the relevant Trust Services Criteria. A consultant-led readiness assessment typically costs $5,000 to $25,000. Some firms roll this into the audit engagement; others bill it separately. If you are starting from scratch, the readiness assessment often surfaces remediation items that would otherwise surface as exceptions during the audit itself, so the upfront investment usually pays for itself.
Remediation Work
The gap analysis from a readiness assessment will almost certainly identify controls you need to build or formalize before the observation period starts. Remediation costs vary widely and depend entirely on where your environment stands today. A company with immature policies and no formal change management process may spend $20,000 to $50,000 on internal engineering and compliance program work. An organization that already has ISO 27001 or a mature information security program may need only a few thousand dollars in targeted gap closure.
Compliance Platform Costs
Many organizations use a compliance automation platform (examples include Vanta, Drata, Secureframe, and Thoropass) to streamline evidence collection and ongoing monitoring. Annual subscription costs generally run $10,000 to $25,000. These platforms reduce auditor hours spent on evidence gathering and can lower the audit fee at firms that integrate with them, so the net cost impact depends on your situation.
Internal Time and Opportunity Cost
SOC 2 audits consume meaningful time from engineering, security, legal, and finance teams. A typical first-year Type 2 engagement requires 200 to 400 hours of internal staff time across scoping, evidence collection, control testing support, and report review. That labor cost is real even when it does not appear on a vendor invoice.
How Long Does a SOC 2 Audit Take?
The timeline depends heavily on report type and how prepared your organization is at kickoff.
Type 1 Timeline
From engagement kick-off to final report, a Type 1 audit generally takes 6 to 12 weeks. That breaks down roughly as follows:
- Scoping and control documentation: 2 to 3 weeks
- Auditor fieldwork: 2 to 4 weeks
- Draft report review and revisions: 2 to 3 weeks
- Final report issuance: 1 to 2 weeks
Organizations that enter the engagement with well-documented controls and a complete system description compress this timeline. Organizations that still need to write policies or formalize processes extend it.
Type 2 Timeline
A Type 2 audit has two distinct phases: the observation period and the audit fieldwork period. The AICPA does not mandate a minimum observation period, but the shortest window commonly seen in practice is 3 months. Most enterprise buyers prefer a 6- or 12-month period.
- Observation period: 3 to 12 months (you run your controls and gather evidence)
- Audit fieldwork: 6 to 10 weeks
- Draft and final report: 4 to 6 weeks
Start-to-finish, plan for 6 to 12 months for a first Type 2 report. After the first year, renewals move faster because the observation period overlaps with normal operations and the firm is already familiar with your environment.
Five Factors That Move the SOC 2 Audit Cost Up or Down
1. Number of Trust Services Criteria in Scope
Security alone produces the leanest scope. Adding Availability, Confidentiality, Privacy, or Processing Integrity each expands the control population the auditor must test and the sample sizes required. Each additional category can add $5,000 to $20,000 in audit fees at a regional firm.
2. Organization Size and System Complexity
Auditors price engagements based on expected hours. A 20-person SaaS company with one primary product and a straightforward AWS environment is far simpler to audit than a 500-person platform with multiple product lines, legacy systems, and subservice organizations. More complexity means more hours, and more hours means a higher fee.
3. Observation Period Length
A 3-month observation period requires less sampling than a 12-month period. If cost is a constraint for a first-time Type 2 engagement, a 3-month period is a legitimate way to manage the initial audit fee while still producing a valid Type 2 report. Just know that many enterprise procurement teams prefer a 12-month period and may ask follow-up questions about a shorter window.
4. Control Maturity at Kickoff
Auditors spend less time when your controls are well-designed, consistently operated, and backed by clean evidence. Organizations that enter a SOC 2 engagement with ad hoc processes, undocumented policies, or gaps identified in prior audits generate more auditor follow-up, more time in fieldwork, and higher fees. The readiness investment before the clock starts is usually worthwhile.
5. CPA Firm Tier and Geography
Specialist boutique firms focused exclusively on SOC audits often offer competitive pricing and fast turnaround. Regional CPA firms with established SOC practices are a strong middle-ground choice for mid-market companies. Mid-tier nationals and Big Four firms bring brand recognition useful for enterprise sales cycles, but the fee premium is substantial.

Year-Two and Beyond: What Annual Renewal Costs Look Like
SOC 2 Type 2 reports are valid for 12 months. Customers expect continuous coverage, which means annual renewal audits. Renewal fees typically run 75 to 90 percent of the initial audit fee because the auditor’s ramp-up work is already done. A company that paid $60,000 for its first Type 2 should budget $45,000 to $55,000 for renewals, assuming scope stays consistent.
Annual compliance platform subscriptions ($10,000 to $25,000) and internal staff time add to the ongoing total. A realistic steady-state annual budget for a mid-market company maintaining a SOC 2 Type 2 with a single observation period runs $50,000 to $100,000 all-in, including audit fees, platform costs, and internal labor.
Is a SOC 2 Audit Worth the Cost?
For service organizations that sell to enterprise customers, handle sensitive data, or operate in regulated industries, SOC 2 has become a sales prerequisite more than a nice-to-have. A well-scoped, clean SOC 2 Type 2 report shortens procurement cycles, eliminates repetitive security questionnaires, and unlocks deals that would otherwise stall in vendor due diligence. For companies at the right stage, the revenue impact of having a current SOC 2 report consistently exceeds the total program cost.
The calculus is different for earlier-stage companies with no enterprise pipeline. If you are under 20 employees and your customers are not yet asking for SOC 2, the investment may be premature. When enterprise deals start stalling on vendor risk assessments, it is time to budget.

Frequently Asked Questions
How much does a SOC 2 audit cost?
A SOC 2 Type 1 audit typically costs $10,000 to $60,000 depending on firm tier and scope. A SOC 2 Type 2 audit runs $15,500 to $150,000 or more. Most mid-market companies working with a regional or specialist CPA firm should budget $30,000 to $75,000 for a first Type 2 engagement covering the Security category. Adding Trust Services Criteria, larger company size, or a Big Four firm pushes the number higher.
How long does a SOC 2 audit take?
A Type 1 audit takes approximately 6 to 12 weeks from kickoff to final report. A Type 2 audit requires 6 to 12 months total when you include the observation period, fieldwork, and reporting. Organizations with mature, well-documented controls compress timelines; those building controls from scratch extend them.
What is the difference between SOC 2 Type 1 and Type 2?
A Type 1 report assesses whether your controls are suitably designed at a single point in time. A Type 2 report tests whether those controls operated effectively over a defined period, typically 3 to 12 months. Type 2 provides stronger assurance and is what most enterprise customers and regulated-industry buyers require before signing vendor contracts.
What drives the cost of a SOC 2 audit up?
The five main cost drivers are: the number of Trust Services Criteria in scope (more categories means more testing), company size and system complexity, observation period length (longer periods require more sampling), control maturity at engagement start, and choice of CPA firm tier (Big Four fees run 3 to 5 times higher than specialist boutiques for comparable scope).
Do SOC 2 reports need to be renewed?
Yes. A SOC 2 Type 2 report covers a specific period and is generally considered current for 12 months after the period ends. Enterprise customers expect continuous, uninterrupted coverage. Annual renewal audits typically cost 75 to 90 percent of the initial audit fee, since the auditor’s upfront ramp-up work is already complete.
Can a company fail a SOC 2 audit?
SOC 2 reports do not produce a pass/fail certification. Instead, the auditor issues an opinion on whether controls are suitably designed (Type 1) or operated effectively (Type 2). If material exceptions exist, the auditor issues a qualified opinion, which can raise red flags with customers. Most organizations use a readiness assessment to identify and close gaps before the observation period begins, specifically to avoid exceptions that would compromise the usefulness of the report.
