When a founder or a Head of Security asks what a SOC 2 audit costs, they are usually asking a narrower question than they realize. The CPA firm's examination fee is only one line item. The total cost of getting to a clean SOC 2 Type 2 report includes readiness work, remediation, GRC tooling, and internal time, and for most companies the examination itself is the smallest part of the first-year bill.
Let us separate the pieces so you can budget accurately and, more importantly, so you can recognize a quote that is too good to be true.
The Examination Fee: What the CPA Firm Charges
The attestation itself must be performed by a licensed CPA firm. That fee is the number most people mean when they say "SOC 2 cost." In 2026, the market breaks down roughly as follows.
| Engagement | Specialist / regional firm | Big Four |
|---|---|---|
| SOC 2 Type 1 | $10,000 – $20,000 | $25,000 – $60,000+ |
| SOC 2 Type 2 (Security only) | $15,000 – $40,000 | $45,000 – $150,000 |
| SOC 2 Type 2 (multiple TSC) | $35,000 – $70,000 | $100,000 – $430,000 |
| Annual renewal | 75% – 90% of the initial examination fee | |
The single biggest lever is firm tier. A specialist CPA firm charges a fraction of what a Big Four office charges for functionally the same scope, and for a Series A to C SaaS company the specialist report carries essentially the same weight with enterprise procurement. The Big Four name matters in a small number of deals, usually where a customer's own vendor risk policy names it. For everyone else, a report from a reputable specialist firm with a clean peer review record is the more sensible spend.
What Moves the Price
After firm tier, the variables that push a quote up or down are predictable. Understanding them lets you scope deliberately rather than react to a number.
| Variable | Effect on cost |
|---|---|
| Number of Trust Services Criteria | Security-only is cheapest. Each added category (Availability, Confidentiality, Processing Integrity, Privacy) increases testing scope and fee. |
| Report type | Type 2 costs more than Type 1 because the auditor tests operating effectiveness across the whole observation period, not design at a point in time. |
| System complexity | More production environments, cloud accounts, and in-scope systems mean more sampling and more evidence to test. |
| Headcount | Larger organizations have more users, access reviews, and onboarding and offboarding events to sample. |
| Audit readiness | The single most controllable factor. A company with clean, complete, well-organized evidence takes fewer auditor hours than one the firm has to chase. |
That last row is where the real money is won or lost. A CPA firm prices partly on how much work it expects your evidence to create. Walk into fieldwork with a curated evidence repository, and the firm spends its hours testing rather than hunting. Walk in disorganized, and you pay for the hunt, often through change orders after the quote.
The Costs That Are Not the Auditor
For most first-time companies, the examination fee is 20 to 40 percent of the true first-year cost. The rest sits in three places.
Readiness and remediation. Before an auditor will test your controls, the controls have to exist and operate. Closing gaps, writing policies, standing up access reviews, and building an evidence program is where the majority of first-year effort goes. This is one-time work; it does not recur at renewal in the same way the examination does.
GRC tooling. Platforms such as Vanta, Drata, and Sprinto typically run $7,000 to $30,000 per year depending on company size and modules. These tools automate evidence collection and are genuinely useful, but they are a starting point, not a substitute for human verification. A GRC platform will happily collect an incomplete or misleading artifact and mark the control green.
Internal time. The least visible cost and often the largest. Someone on your team owns the evidence, answers auditor requests, and manages remediation. For a lean security or engineering team, this can consume a meaningful share of a person's quarter.
Budget the program, not the auditA useful rule of thumb for a first SOC 2 Type 2: expect the examination fee to be the smallest of your four line items, behind readiness and remediation, GRC tooling, and internal time. Companies that budget only for the auditor are the ones surprised in month three.
Why the Cheapest Quote Is a Warning, Not a Win
A legitimate Security-only SOC 2 Type 2 requires at least 60 to 80 auditor hours across planning, walkthroughs, evidence testing, report drafting, and internal quality review. At standard professional rates, that puts a realistic floor around $9,000 to $15,000. When a quote comes in at $3,000 to $5,000, the arithmetic does not support meaningful testing. There simply are not enough hours in the engagement to perform inquiry, observation, inspection, and reperformance across a full period.
The result is usually a templated report with minimal audit work behind it. That report may satisfy a checkbox in the short term, but it is exactly the kind of artifact that the 2026 scrutiny of automated compliance has taught sophisticated vendor risk reviewers to discount. A report that cost you almost nothing tells an experienced buyer almost nothing. This is the central lesson of the last two years: cheap, fast, automated attestation created a market full of reports that do not survive a serious second look.
One More Check Before You Sign
Whatever you pay, verify the firm's peer review record before you engage. Every CPA firm performing AICPA-standard attestation must undergo an independent peer review every three years, and the results are public through the AICPA Peer Review database. A firm that does not appear, shows an expired review, or carries deficiencies is a red flag regardless of how attractive the price looks. Price is easy to compare. The credibility of the opinion behind the report is what your customers are actually buying.
If you want to understand where your evidence and controls sit before you take a single quote, a readiness assessment is the cheapest way to control the largest cost variable in the whole engagement. It is far less expensive to find your gaps on your own timeline than to discover them during fieldwork you are already paying for by the hour.
