Pricing data sources.

Every cost range on SOC 2 audit cost traces back to one of the entries below. Each entry carries its calculation method, the source URL where one exists, and the date we last refreshed it. Audit fees move; we keep these dated so a reader can judge how recent the data is.

The four-tier evidence-weighting model behind these entries is documented in our methodology at /methodology/#source-tiers. Verification cadence triggers at /methodology/#verification-cadence.

Auditor tier ranges

Aggregate planning bands per (firm tier × audit type), recomputed from our directory data on every build. Each band runs from the median of the firms’ listed minimum estimates to the median of their listed maximum estimates. These are not observed transaction prices or live quotes, and individual proposals can fall outside the band in either direction.

Specialist auditors — SOC 2 Type 1

$10K–$33.0K

Last refreshed2026-08-03

Computed from the boutique specialist firms in our maintained dataset: the median of their directory-listed Type 1 minimum estimates through the median of their listed maximum estimates. These are planning values, not observed transaction prices or live quotes. Recomputed on every build.

Specialist auditors — SOC 2 Type 2

$15K–$50K

Last refreshed2026-08-03

Median of the directory-listed Type 2 minimum estimates through the median of the listed maximum estimates across the boutique specialist firms in our maintained dataset. These are planning values, not observed transaction prices or live quotes; proposals can fall outside the band in either direction. Recomputed on every build.

Regional firms — SOC 2 Type 1

$15K–$40K

Last refreshed2026-08-03

Median of the directory-listed Type 1 minimum estimates through the median of the listed maximum estimates across the regional CPA firms with a SOC 2 practice in our maintained dataset. These are planning values, not observed transaction prices or live quotes. Regional means partner-staffed offices outside the big national networks. Recomputed on every build.

Regional firms — SOC 2 Type 2

$20K–$55K

Last refreshed2026-08-03

Median of the directory-listed Type 2 minimum estimates through the median of the listed maximum estimates across the regional CPA firms in our maintained dataset. These are planning values, not observed transaction prices or live quotes. Recomputed on every build.

Mid-tier and national firms — SOC 2 Type 1

$20K–$60K

Last refreshed2026-08-03

Mid-tier and national CPA firms (RSM, Grant Thornton, BDO, Baker Tilly and peers) pooled into one population, then the median of their directory-listed Type 1 minimum estimates through the median of their listed maximum estimates. These are planning values, not observed transaction prices or live quotes. Pooled over the firms themselves, not averaged from two separate tier medians. Matches the directory's 'Mid-tier and national' tier section. Recomputed on every build.

Mid-tier and national firms — SOC 2 Type 2

$30K–$80K

Last refreshed2026-08-03

Mid-tier and national CPA firms pooled into one population, then the median of their directory-listed Type 2 minimum estimates through the median of their listed maximum estimates. These are planning values, not observed transaction prices or live quotes; proposals vary with scope. Recomputed on every build.

Big Four firms — SOC 2 Type 1

$40K–$140K

Last refreshed2026-08-03

Big Four = Deloitte, PwC, KPMG, EY. Our entries cover the four firms across multiple regions and service lines, and the band is the median of their directory-listed Type 1 minimum estimates through the median of their listed maximum estimates. These are planning values, not observed transaction prices or live quotes; proposals vary sharply by office and engagement scope. Recomputed on every build.

Big Four firms — SOC 2 Type 2

$60K–$200K

Last refreshed2026-08-03

Median of the directory-listed Type 2 minimum estimates through the median of the listed maximum estimates across the Big Four offerings in our maintained dataset. These are planning values, not observed transaction prices or live quotes; proposals vary by office, scope, entity count, and region. Recomputed on every build.

Add-on costs

Costs that sit alongside the audit fee. Pen test, GRC platform, internal labor, scope creep, report amendments. Each entry identifies whether it comes from a vendor page, the sourced software registry, or a buyer-reported aggregate from this site.

GRC / compliance automation platform (annual)

$3.6K–$80K

Last refreshed2026-08-12

Envelope across sourced annual USD observations in the software registry. It mixes vendor-confirmed figures and clearly labeled third-party estimates; quote-only vendors without an observed price are omitted. This is a planning span, not a typical price or a live quote.

Internal engineering and founder hours during audit prep

$25K–$90K

Last refreshed2026-05-13

Reflects 300–600 hours of engineering, security, and founder time during a first SOC 2 Type 2 — buyer-reported. Range computed at $80–$150/hr loaded labor cost. Smaller teams with stronger baselines land at the low end; greenfield mid-market orgs at the high end.

Control remediation (tooling, vendors, hardware)

$5K–$50K

Last refreshed2026-05-13

Covers tooling and vendor spend triggered by readiness gaps: MDM, IdP, logging or SIEM, vulnerability management, background-check service, security training. Highly dependent on starting maturity. Greenfield orgs land above this band.

Scope creep and change orders during audit

$10K–$30K

Last refreshed2026-05-13

Triggered by mid-engagement additions: extra trust services criteria, additional in-scope systems, late-binding subservice organizations, or remediation that became audit work.

Report amendments and reissue fees

$2K–$5K

Last refreshed2026-05-13

Charged when a buyer requests an updated report after issuance — for example, to add a subservice organization, fix a factual error, or refresh the system description for a customer that requires it.

Market mentions (reviewed third-party price points)

Single third-party price points — first-person buyer reports in public threads and figures published in auditor or compliance-platform guides. Each survived a manual review pass (duplicates, ambiguous amounts, and low-credibility sources rejected). Corroboration for the tier ranges above; never an input to them.

Platform estimate — Type 1 (Drata)

$11.3K

Last refreshed2026-06-11

Midpoint of the Type 1 estimate in Drata’s dedicated cost guide. A conflicting higher figure on their type-1-vs-type-2 marketing page was rejected in review.
