What does SOC 2 actually cost?
SOC 2 cost splits into three distinct parts. Most articles blend them together and give you a total number that makes realistic budgeting difficult. This page separates each part clearly, and is honest about what we know and do not know.
Before you read further
Most SOC 2 cost numbers you find online are sourced from the US market. Aggregate price ranges from online sources were not independently verified and vary widely based on scope, auditor, and company size. The one number we can cite with confidence: a consultant-led readiness assessment costs $5,000-$20,000 at US market rates. For the Vietnamese market, contact at least 2-3 CPA firms directly for quotes that reflect local context.
The three parts of SOC 2 cost
Readiness assessment
The gap analysis done before the audit begins. It tells you which controls are missing and what needs to be built before the auditor arrives.
This is the number we can cite with the most confidence. If your team has the expertise, you can run this internally and avoid the cost entirely.
The audit fee (CPA firm)
The fee paid directly to the CPA firm that performs the audit. This is the hardest fixed cost of the three.
- Number of Trust Service Criteria in scope
- Type I vs Type II
- System size and complexity
- Big 4 vs boutique CPA firm
Internal effort and annual maintenance
Often the largest cost, and the most frequently underestimated. Internal staff need time to build controls, collect evidence, and maintain them year after year.
What drives the final number up or down?
Trust Service Criteria
Security-only is the minimum scope and cheapest. Adding Availability, Confidentiality, or Processing Integrity increases both the audit fee and internal effort.
Type I vs Type II
Type I checks controls at a single point in time. Type II requires a 6-12 month observation period. Type II typically costs 30-50% more but carries more weight with US buyers.
Maturity of existing controls
If you already have ISO 27001 or a solid security foundation, most controls are already in place. Starting from scratch takes substantially more time and internal cost.
System size in scope
Larger systems mean more components to test. Auditors typically price based on hours or system complexity.
Compliance platform vs manual
A platform automates evidence collection and cuts internal staff hours. The CPA audit fee itself does not change, but total real cost is typically lower because of the staffing savings.
Choice of CPA firm
Big 4 firms are typically more expensive but their brand carries weight with some enterprise buyers. Boutique SOC 2 specialists often offer competitive rates with comparable quality.

How to budget for SOC 2
Start with a readiness assessment
This is the cost you can predict and should do first. The output tells you exactly what needs to be built, which gives you a much better basis for estimating internal effort.
Get quotes from multiple CPA firms
Audit fees vary significantly between firms. Contact at least 2-3 SOC 2-experienced CPA firms and compare before committing. Do not decide based on a single quote.
Factor in 6-12 months of internal staff time
Staff hours are typically the largest cost but the least visible in a budget. Account for the initial control build and the ongoing evidence collection and annual maintenance.
Weigh a compliance platform against doing it manually
A platform automates evidence collection and reduces staff hours. Platform cost is offset by staffing savings, particularly when maintaining SOC 2 across multiple years or running multiple frameworks simultaneously.
Frequently asked questions
How much does SOC 2 Type I vs Type II cost?
Type I is usually cheaper because there is no observation period. Type II costs more because the auditor tests controls over 6-12 months. The difference is typically 30-50% depending on the auditor and scope. Get quotes from at least 2-3 CPA firms before deciding.
Does a compliance platform reduce SOC 2 cost?
Yes, but the savings come from reducing internal effort, not the audit fee itself. The audit fee paid to the CPA firm remains fixed. A platform helps automate evidence collection, reduces internal prep hours, and prevents cost overruns from missing documentation.
What are the hidden costs of SOC 2?
Commonly overlooked costs: staff hours to build and maintain controls (often larger than the audit fee), tools and infrastructure to collect evidence, additional security staff or consultants, and annual audit fees to keep the report current.
