What does a SOC 2 audit cost?
Published vendor estimates put a SOC 2 Type I audit roughly in the $5,000 to $20,000 range and a Type II from about $7,000 into six figures depending on scope, with small companies commonly at the lower end. The audit fee is only part of the total: readiness work, a penetration test, tooling, and internal time usually make the all-in first-year cost larger than the auditor invoice.
The audit fee is the small number
Published estimates from compliance vendors put a SOC 2 Type I audit roughly in the $5,000 to $20,000 range, and a Type II anywhere from about $7,000 into six figures depending on scope, with SMBs commonly at the lower end. Scope drives most of the variance, so treat these as ranges, not quotes.
The all-in cost is larger
Add a readiness assessment, a penetration test, tooling, and internal staff time, and the first-year all-in cost is typically well above the auditor fee. The expensive part of SOC 2 is usually preparation and evidence, not the audit invoice itself.
How to lower it
A readiness assessment first avoids surprises, continuous evidence avoids a last-minute scramble, and reusing controls across frameworks means later frameworks are mostly reuse. Keel is built for exactly this, and our research report breaks the numbers down with cited sources.
FAQ
Why is Type II more expensive than Type I?
Type I assesses control design at a point in time, while Type II assesses whether controls operated over a period (commonly 3 to 12 months). The longer scope and evidence review make Type II cost more.
Is the audit fee the whole cost?
No. Readiness work, a penetration test, tooling, and internal time usually add up to more than the audit fee, so budget for the all-in cost, not just the auditor invoice.
