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 and our verification cadence are documented in our methodology.

How does the calculator turn prices into a budget?

The calculator starts from a lower-cost specialist audit fee, then adjusts for team size and scope. The output is a planning budget, not a market average or a quote from any one firm.

Starting range

The base is a published specialist audit fee for teams with documented startup fit: $5,000–$7,000 for Type 1 and $7,000–$10,000 for Type 2. One firm's published range is not evidence of what most startups pay.

Teams of up to 50 people share that starting range. Every budget below assumes Security-only scope, one simple system, and controls ready for testing.

How larger teams are adjusted

Size allowances draw on anonymized buyer quotes and published specialist pricing schedules. The quote sample is strongest for small teams. For larger teams, published fee tiers fill the gap when there are too few comparable quotes to plot a reliable curve. Packages that bundle readiness or advisory work stay out of the audit-only figure. The calculator rounds to the nearest $500 and never shows individual offers.

Starting budgets by team size

Security only, one simple system, controls ready for testing.

Team sizeType 1 budgetType 2 budget
1–10 employees$5,000–$7,000$7,000–$10,000
11–50 employees$5,000–$7,000$7,000–$10,000
51–200 employees$7,500–$10,500$10,500–$15,000
201–500 employees$10,000–$14,000$16,000–$22,500

For full-service CPA and Big Four firms, request a scoped proposal. The guide's directory bands compare firm groups; they do not price your engagement.

The calculator's full-service comparison uses the middle half of firms' listed price-range midpoints, without size or scope adjustments. The guide's table runs from the median listed minimum to the median listed maximum. Both summarize directory estimates, not quote-derived budgets.

Scope adjustments

After the size allowance, the calculator applies adjustments for Trust Services Criteria count and system footprint. Footprint takes the largest of system complexity, vendor count, or office locations, because those factors overlap. Readiness work is flagged separately and never added to the audit fee. Teams above 500 people or with the most complex system option are sent to a scoped quote instead of a precise number.

Auditor organization-group ranges

Aggregate planning bands per (organization group × audit type), recomputed whenever we refresh our auditor directory. Each band runs from the median of the firms’ listed minimum estimates to the median of their listed maximum estimates. These are descriptive cohorts, not quality or capability scores, and individual proposals can fall outside the band.

Assurance specialist firms — SOC 2 Type 1

$10K–$35K

Last refreshed2026-08-03

Computed from the assurance specialist firms in our auditor directory: 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. Refreshed whenever we update our auditor directory.

Assurance specialist firms — SOC 2 Type 2

$15.5K–$50K

Last refreshed2026-08-03

Median of the directory-listed Type 2 minimum estimates through the median of the listed maximum estimates across the assurance specialist firms in our auditor directory. These are planning values, not observed transaction prices or live quotes; proposals can fall outside the band in either direction. Refreshed whenever we update our auditor directory.

Full-service CPA firms — SOC 2 Type 1

$20K–$60K

Last refreshed2026-08-21

Median of the directory-listed Type 1 minimum estimates through the median of the listed maximum estimates across generalist CPA firms (national networks through regional full-service shops) in our auditor directory. These are planning values, not observed transaction prices or live quotes. Refreshed whenever we update our auditor directory.

Full-service CPA firms — SOC 2 Type 2

$30K–$80K

Last refreshed2026-08-21

Median of the directory-listed Type 2 minimum estimates through the median of the listed maximum estimates across generalist CPA firms in our auditor directory. These are planning values, not observed transaction prices or live quotes; proposals vary with scope. Refreshed whenever we update our auditor directory.

Big Four firms — SOC 2 Type 1

$40K–$145K

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. Refreshed whenever we update our auditor directory.

Big Four firms — SOC 2 Type 2

$65K–$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 auditor directory. These are planning values, not observed transaction prices or live quotes; proposals vary by office, scope, entity count, and region. Refreshed whenever we update our auditor directory.

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, our GRC software directory, or a buyer-reported aggregate from this site.

GRC / compliance automation platform (annual)

$3.6K–$78.1K

Last refreshed2026-09-30

Envelope from comparable annual USD prices observed in our GRC software directory. It mixes vendor-confirmed figures and clearly labeled third-party estimates; vendors without a published or quoted 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 excluded after manual review.
