SOC2 Audit Cost by Company Size
The biggest driver of SOC2 audit cost is company size — specifically, how many systems, integrations, and employees the auditor must assess. Here are realistic 2026 price ranges based on firm outreach and client data.
| Company Size | SOC2 Type 1 | SOC2 Type 2 | Best Auditor Type |
|---|---|---|---|
| 1–10 employees | $7K–$15K | $12K–$25K | Boutique specialist |
| 11–50 employees | $12K–$25K | $20K–$45K | Boutique / Specialist |
| 51–200 employees | $18K–$40K | $30K–$75K | Specialist / Mid-size |
| 201–500 employees | $30K–$75K | $50K–$120K | Mid-size regional CPA |
| 500+ employees | $60K–$150K | $100K–$400K | Big 4 / National CPA |
Ranges assume security TSC only, single cloud provider (AWS/GCP/Azure), no FedRAMP/HITRUST requirements. Adding TSC or complex multi-cloud architecture increases costs by 20-60%.

The auditor's fee is often only 40-60% of the total SOC2 investment. Budget for these additional costs:
How to Reduce SOC2 Audit Costs
- Use a GRC platform before starting. Vanta and Drata automate 70%+ of evidence collection. Auditors who partner with these platforms charge 15-25% less and complete the audit faster. The platform subscription pays for itself.
- Scope conservatively. Start with Security TSC only. Add Availability or Confidentiality only if your specific customers contractually require it. Each additional TSC adds 15-25% to the audit cost.
- Get Type 1 first. If you're under time pressure, get Type 1 quickly (4-8 weeks, 40% cheaper). Many enterprise buyers will accept Type 1 as an interim while Type 2 is in progress.
- Choose a specialist boutique over Big 4. For startups through Series C, a specialist boutique typically produces an equally accepted report at 30-60% lower cost with faster turnaround.
- Do the readiness work yourself. A good GRC platform + 2-3 months of internal focus before engaging the auditor means fewer billable hours fixing issues during the audit.
- Ask for a fixed-fee quote. Some boutique firms offer fixed-fee SOC2 engagements. This protects you from cost overruns if remediation takes longer than expected.
Frequently Asked Questions
How much does a SOC2 Type 2 audit cost?
A SOC2 Type 2 audit costs $15,000–$400,000 depending on company size, number of Trust Services Criteria, and auditor type. Small startups (under 50 employees, security TSC only) typically pay $20,000–$45,000. Mid-size companies (50-200 employees) pay $30,000–$75,000. Enterprise companies working with Big 4 firms pay $100,000–$400,000.
Is SOC2 Type 1 cheaper than Type 2?
Yes. SOC2 Type 1 is typically 30-50% cheaper than Type 2 for the same company. Type 1 does not require an observation period, so the auditor's time is significantly less. A startup that pays $30,000 for Type 2 would typically pay $12,000-$18,000 for Type 1.
Does using Vanta or Drata reduce SOC2 audit costs?
Yes, meaningfully. Companies using GRC platforms like Vanta or Drata typically pay 20-30% less for SOC2 audits because evidence collection is automated. Auditors who are official platform partners can pull evidence directly, reducing the 400-600 hours of manual evidence collection that would otherwise be billed to you. Auditors with direct Vanta or Drata integrations often offer lower fees for platform users.
What are hidden SOC2 audit costs?
The audit fee is often 40-60% of total SOC2 costs. Hidden costs include: GRC platform subscription ($15,000-$35,000/year for Vanta or Drata), remediation work (patching gaps before the audit, often $20,000-$100,000+ in engineering time), a readiness assessment ($5,000-$15,000), policy writing ($3,000-$8,000 if outsourced), and annual renewal costs (typically 60-80% of the original audit fee).
Can I get a cheap SOC2 audit under $15,000?
SOC2 Type 1 audits for very small startups (under 10 employees, minimal infrastructure) can start at $7,000-$12,000 from boutique CPA firms. However, be cautious of unusually low quotes — they often signal inexperienced auditors, aggressive scoping exclusions, or junior-only engagement teams. A report that doesn't satisfy your enterprise buyers is worthless. For Type 2, realistic minimums are $15,000-$18,000.
How much does SOC2 renewal cost?
SOC2 Type 2 renewal (annual re-audit) typically costs 60-80% of the original audit fee if you stay with the same auditor. The observation period is still required (usually shortened to 6 months for renewals), but auditors can reuse prior-year workpapers and skip many setup steps. Switching auditors for renewal typically costs 90-100% of the original fee due to re-familiarization.
