SOC 2 Audit Cost Breakdown: What the $20K-$80K Range Actually Covers

The audit firm fee is the smallest line item in most first-time SOC 2 budgets. Quotes that say “SOC 2 audit cost: $20,000” describe one component out of six — and the other five are where small companies blow their budget. How much does a SOC 2 audit cost a small company? Realistically, $20,000 to $80,000 in year one, with the audit firm taking a $15,000–$25,000 slice of that.

This breakdown walks each component, what it actually pays for, and where the hidden costs live. It assumes a small company (under 100 employees) pursuing a first-time Type 2 examination on Security only or Security plus Availability.

The Six Components of First-Year SOC 2 Audit Cost

Below, each component in detail.

1. Readiness Assessment: $0 to $15,000

The readiness assessment is the pre-audit review that maps your current controls against the Trust Service Criteria. It outputs three things: a list of gaps, a remediation plan, and an estimate of how long until you’re audit-ready.

You have two paths:

• Self-assessment. Free. Use a structured tool that mirrors what an auditor evaluates. Our free SOC 2 gap assessment covers the AICPA control inventory with weighted scoring. Self-assessments tend to overestimate readiness by 20–30% — treat the score as optimistic and plan a margin.
• Professional readiness assessment. $3,000–$15,000. Performed by a CPA firm using auditor methodology. Catches gaps a self-assessment misses, especially in governance controls (CC1) and operational controls (CC7–CC9). Often bundled with the audit engagement.

If your team has done a SOC 2 before or you have a strong security/compliance lead, self-assess first and pay for professional review only if the score lands in “Nearly Ready” territory and you want auditor-grade validation. If this is your first compliance framework and you don’t know what you don’t know, pay for professional readiness up front. The cost is a fraction of a misjudged audit timeline. Our SOC 2 readiness assessment checklist covers what auditors actually test, control by control.

2. Remediation: $10,000 to $50,000+

Remediation is the variable cost. It depends entirely on the gap inventory the readiness assessment surfaced. Common line items:

• Identity and access controls (CC6): SSO rollout, MFA enforcement, quarterly access review tooling, deprovisioning automation. $5,000–$20,000 if you don’t already have these. CC6 is the most commonly failed area, so this is where most companies spend.
• Policy authoring: Acceptable use, incident response, change management, vendor management, BCP/DR — auditors expect roughly 20 distinct policies. Templates exist; customizing them to your actual practice takes 40–80 hours of internal time or $3,000–$10,000 for a consultant.
• Vulnerability scanning and pen test prerequisites: A continuous vulnerability scanner is typically expected. $2,000–$8,000/year.
• Logging and monitoring (CC7): Centralized logging, alerting on security events. If you don’t have a SIEM or equivalent, expect $5,000–$15,000 in tooling and configuration time.
• Vendor management (CC9): Vendor risk inventory, security questionnaire workflow, ongoing monitoring. Often built in spreadsheets initially; $2,000–$5,000 if you adopt a tool.

Companies starting from a mature security baseline spend $10,000–$20,000 here. Companies starting from scratch — no formal access reviews, ad-hoc deployment process, no documented policies — can spend $40,000–$60,000 before they’re ready to start the observation period.

3. Compliance Automation Platform: $8,000 to $25,000/year

Vanta, Drata, Secureframe, and Sprinto sit in this category. They automate evidence collection from your cloud infrastructure, identity provider, HR system, and code repositories. They reduce the audit-prep work from weeks of screenshot collection to continuous automated monitoring.

What they actually do: pull configuration evidence via API integrations, monitor controls continuously, flag drift, store policy templates, manage vendor inventories. What they don’t do: implement security controls, fix infrastructure gaps, write your custom policies, or perform the audit.

For a sub-50-employee company on standard SaaS infrastructure, expect $10,000–$15,000/year for the platform. The platforms are commoditized at the small-company tier; pick on integration coverage with your stack rather than on feature count. You can run a SOC 2 audit without one (manual evidence collection is workable for the first audit), but the labor cost typically exceeds the platform cost after the first year.

4. Penetration Test: $8,000 to $20,000

This is the cost most first-time companies miss in early budgets. SOC 2 doesn’t mandate a pen test by name, but auditors testing CC7 (System Operations) typically expect annual penetration testing as evidence that vulnerability management is operating. Skipping it usually triggers a control deficiency.

Quality range: $8,000–$12,000 buys an automated-scan-plus-light-manual-review report. $15,000–$20,000 buys a manual penetration test from a credentialed firm with detailed findings. For a SOC 2 examination on a SaaS application, the manual end of that range is the safer evidence.

5. Audit Firm Fee: $15,000 to $25,000 (Small Company Type 2)

This is the line item most people mean when they say “SOC 2 audit cost.” Big 4 firms quote $100,000+ for small companies and aren’t the right fit. Mid-tier and boutique CPA firms quote $15,000–$25,000 for first-time Type 2 on Security-only scope. Adding Availability typically adds $2,000–$5,000. Adding Confidentiality, Processing Integrity, or Privacy each adds another $2,000–$5,000.

Quotes below $8,000 for a Type 2 are a red flag. AICPA standards require enough fieldwork that a legitimate engagement can’t come in cheaper than that — below the line, you’re paying for an attestation the firm couldn’t responsibly issue. See the AICPA SOC 2 framework guidance for the practitioner standards that drive minimum engagement scope.

For a Type 1 first (the report on point-in-time control design), expect $7,500–$15,000 from the same firm tier. Whether to do Type 1 first is a separate decision — covered in our guide to selecting Trust Service Criteria.

6. Internal Time: 100 to 200 Hours

The hidden cost. Compliance work pulls from engineering, IT, security, HR, and management. Typical first-time Type 2:

• Compliance lead or project owner: 80–120 hours over 6–9 months
• Engineering: 30–50 hours (evidence requests, control implementation, security reviews)
• HR / people ops: 10–20 hours (policy review, training records, access provisioning workflows)
• Leadership: 10–20 hours (governance, risk assessment, management assertion)

At a fully-loaded $100/hour, that’s $10,000–$20,000 in opportunity cost not reflected on any invoice. Companies that miss this in planning end up either under-resourcing the audit and missing milestones, or pulling a critical engineer off product for a quarter.

Year-Two and Ongoing Costs

The first audit is the expensive one. Year-two costs drop because remediation is mostly done and policies are written. Typical ongoing:

• Audit renewal (Type 2, 12-month period): $12,000–$25,000/year
• Compliance platform: $10,000–$20,000/year
• Pen test: $8,000–$15,000/year
• Internal time: 60–100 hours/year (lower because evidence collection is automated and policies just need annual review)

Realistic ongoing total: $30,000–$60,000/year. That’s the steady-state cost of being a SOC-2-compliant small company.

Where Small Companies Actually Save

Three patterns work:

1. Tight scope. Don’t add optional Trust Service Criteria your customers haven’t asked for. Each criterion adds $2,000–$5,000 in audit fees plus weeks of evidence collection. Security-only is the right starting scope for most.
2. Self-readiness, professional audit. Run the readiness assessment yourself; pay the CPA firm for the actual examination. Saves $3,000–$15,000 without affecting audit quality if your self-assessment is honest.
3. Bundled engagements. Some firms offer readiness-plus-audit bundles at modest discount. Trade-off: AICPA independence rules limit how much remediation guidance the audit firm can provide, so you may end up with less hand-holding through gap closure.

What doesn’t work: skipping the compliance platform, skipping the pen test, or treating the project as IT-only. Each of these compresses the budget on paper and inflates it in practice.

Where to Start

Before you ask audit firms for quotes, run a control-level gap assessment. Knowing your readiness tier and your top gaps tells you whether you’re looking at $25,000 or $75,000 in year one — and that determines which audit firms are even worth a call. Our free SOC 2 gap assessment takes about 30 minutes and produces a remediation cost estimate alongside the readiness score.
