SOC 2 Compliance Cost: Budget Planning Guide

Reviewed by Marcus Dunhill, CISA, CISSP

SOC 2 costs $100,000 to $350,000 in the first year for a typical mid-market company when you include auditor fees ($30,000 to $150,000), internal labor ($50,000 to $150,000), and hidden costs like tooling, remediation, and contractor support. According to ISACA's 2024 State of IT Audit survey, 61% of organizations exceed their initial SOC 2 budget — primarily because internal labor costs are underestimated by an average of 40%. Subsequent years drop 30% to 40% once the foundation is built.

You got a quote for SOC 2 and it's way more than you expected. Is this vendor overcharging you or is that actually what this costs? The answer depends on understanding what drives the price. SOC 2 cost varies wildly — from $30,000 for a tiny company with simple infrastructure to $300,000 or more for a large company with complex systems. Understanding what you're paying for helps you evaluate whether a quote is reasonable and whether SOC 2 makes financial sense for your business.

The cost has multiple components: auditor fees, your internal labor, scope complexity, and remediation if the audit reveals controls that aren't working. Most companies dramatically underestimate the internal labor cost, which often exceeds the auditor fees themselves. This guide breaks down the components so you can build a realistic budget and evaluate whether quotes are in the ballpark.

Auditor Fees and What They Actually Cover

Auditor fees typically range from $30,000 to $150,000 for a complete SOC 2 Type 2 audit at a mid-market company. Type 1 audits cost less because they require less time — typically $15,000 to $50,000. The variability is driven by company size, system complexity, and which Trust Service Criteria are in scope.

A 10-person company with a single SaaS platform and straightforward cloud infrastructure will land at the lower end — $20,000 to $30,000 for Type 1 and $40,000 to $60,000 for Type 2. A 500-person company with multiple products, multiple data centers, and high compliance requirements will pay at the high end — $80,000 to $150,000 for Type 2. The difference comes from the auditor's time estimate, which is based on how long they think the job will take.

Auditors typically charge by the hour ($150 to $400 per hour depending on seniority and firm size) or by a fixed project fee. When they give you a quote, they're estimating how many hours the audit will take based on your size and complexity. The estimate includes scoping and planning the engagement, gathering evidence and documentation, fieldwork and actually testing controls, remediation support if you need help fixing findings, and report writing.

Auditor fees also depend on which firm you hire. Big 4 accounting firms and large regional compliance shops charge more than boutique compliance firms. You're paying for expertise and reputation. A Big 4 firm brings credibility that some enterprise customers value. A boutique firm brings specialized expertise in SOC 2 and is more cost-effective for smaller companies. Neither choice is inherently right; it depends on what your customers care about and what your budget can bear.

When getting quotes, shop around. Get quotes from three to five auditors. Ask specifically what's included in their estimate and whether travel costs, overtime, or additional testing would be extra. This is where hidden costs live. A quote that doesn't include travel might be cheaper upfront, but if your auditor needs to visit your offices, you're suddenly paying for flights and hotels.

The Largest Hidden Cost: Your Internal Labor

This is where companies get surprised. Auditor fees might be $50,000, but getting to the point where the auditor can do their job requires 3 to 6 months of your staff's time. For a 50-person company, budget for roughly 500 to 1,000 hours of internal labor over the 6-month preparation phase. For a 200-person company, budget for 1,500 to 3,000 hours. This varies wildly based on how much documentation and control maturity you already have. If you're starting from scratch with no policies and no logging infrastructure, budget on the high end. If you already have most controls documented and operating, you might get away with 300 to 500 hours.

Here's the real cost calculation: 1,000 hours at an average fully-loaded cost of $75 per hour equals $75,000. That's often more than what you're paying the auditor. But companies don't count this as a "cost" because they're not writing a check outside the company. They should. The opportunity cost is real — your IT staff is doing SOC 2 preparation instead of other projects, new features, infrastructure improvements, or whatever else is on their backlog.

Factor this into your budget and timeline realistically. This is why small companies decide SOC 2 isn't worth it when the internal labor cost is $75,000 and the incremental revenue from getting SOC 2 is only $10,000 annually. The internal labor burden is also why timing matters. If you do SOC 2 during a slow season when you don't have competing priorities, the opportunity cost is lower than if you do it during a busy season when you need those people on other critical projects.

Scope Complexity and How It Affects Costs

A smaller scope means lower auditor fees. A larger scope means higher fees. Scope is determined by which systems, processes, and Trust Service Criteria are being evaluated. For a small company with a single SaaS platform, scope might be narrow: just the production infrastructure, the Security criterion, and not Availability or Processing Integrity. For a large company with multiple products, multiple data centers, multiple office locations, and customers in multiple jurisdictions, scope is huge: multiple systems, multiple criteria, complex interactions between systems, compliance requirements in different countries.

Bigger scope means more testing, more documentation to review, more controls to verify. If your scope includes "we encrypt all customer data at rest and in transit and we continuously monitor for any unencrypted data," that's more complex than "we encrypt data in our primary database." If your scope includes "we maintain a disaster recovery plan and test it quarterly," that's more work to verify than "we maintain a disaster recovery plan." The auditor has to look at actual test results, not just policy.

Scope creep during the audit is a cost driver and a timeline killer. You start with a narrow scope to save money, then customers ask about controls outside that scope. You end up expanding scope mid-audit and paying more. The auditor has to re-test, re-document, and adjust their findings. This is why getting scope right at the beginning — during your initial planning phase — matters. Have a realistic conversation with your auditor about what scope makes sense given your customer base and your goals. Be strategic about what you include and what you exclude.

First Audit vs Ongoing Annual Audits

Your first SOC 2 audit is the most expensive because you're building everything from scratch: documentation, control implementation, evidence gathering infrastructure, processes that didn't exist before. Subsequent annual audits are typically 30% to 40% cheaper because you already have the foundation in place.

Here's the typical cost progression. Year one Type 2 is typically $50,000 to $150,000 in auditor fees plus $75,000 to $150,000 in internal labor — total first-year cost of $125,000 to $300,000. Year two Type 2 is usually $35,000 to $100,000 in auditor fees plus $25,000 to $50,000 in internal labor — total of $60,000 to $150,000. Year three and beyond are similar to year two unless your scope expands or you switch auditors.

If you switch auditors, you'll pay closer to first-year costs because the new auditor needs to re-understand your environment and re-test controls they didn't audit before. If you expand scope to include new systems or additional Trust Service Criteria, you'll pay more. But if you keep scope stable and stay with the same auditor, costs stabilize significantly. This is why it's important to think of SOC 2 as an ongoing program, not a one-time project. The first year is expensive but subsequent years are more manageable. Budget accordingly.

Remediation Costs if Controls Fail Testing

If the auditor's testing reveals that a control didn't work as described, you need to fix it and potentially have the auditor re-test. Remediation cost depends on what needs to be fixed. A simple remediation like "we need to document that we do quarterly access reviews and provide evidence that we actually did them" takes a week and costs internal labor time. A complex remediation like "we need to implement encryption for customer data that's currently unencrypted" takes months and costs significant engineering time, plus possibly vendor costs for encryption tools or infrastructure.

Auditors give guidance on whether they need to re-test after remediation and how much additional time that will require. If you have a few minor findings — documentation gaps, one-time misses in quarterly processes, timing issues — the auditor might accept your evidence of remediation without re-testing. If you have significant control failures, the auditor requires follow-up testing which adds 2 to 4 weeks and $5,000 to $20,000 in additional auditor fees.

In worst-case scenarios where significant controls fail testing, you might need a second abbreviated audit to verify the fixes. That costs $15,000 to $40,000 and delays your SOC 2 report by several months. This is why getting controls right before the auditor arrives matters. According to Coalfire's 2023 audit trends data, approximately 65% of first-time SOC 2 audits have at least one exception — plan for 1 to 2 weeks of remediation work and $1,000 to $2,000 in additional auditor fees for re-testing even in a relatively clean audit.

Hidden Costs Vendors Don't Mention Upfront

Auditor quotes usually don't include costs that surface during the engagement. Travel costs if your auditor needs to visit your offices — flight, hotel, meals — add $2,000 to $5,000 depending on location. Overtime or contractor fees if you need help pulling together evidence add $10,000 to $30,000. Software costs if you need to implement logging or monitoring infrastructure that doesn't exist yet run $5,000 to $50,000 depending on what's needed. Training costs if your staff needs to learn about new systems or processes add additional budget.

A common hidden cost is logging infrastructure. If you claim that you monitor for security incidents but you don't have comprehensive logging in place, you need to implement logging infrastructure before the audit even starts. Depending on your environment, this costs $5,000 to $50,000 and adds 1 to 3 months to your timeline. Another is contractor help. Some companies hire a compliance contractor during preparation to help with documentation and evidence gathering. That's an additional $10,000 to $30,000. A third is GRC software to manage evidence and documentation, which runs $5,000 to $15,000 per year.

Be explicit with your auditor about what's included in their quote and what would be additional. Get itemized quotes so you're not surprised at the end.

Evaluating Quotes and Negotiating Fairly

When you have three to five auditor quotes, evaluate them by looking beyond the headline number. A $40,000 quote that doesn't include travel might not be cheaper than a $50,000 quote that does. A quote that assumes you already have documentation might not account for remediation cost if you don't actually have the controls you claim. Ask for an itemized breakdown: planning and scoping, fieldwork and testing, remediation support, and report writing. This shows you what time is going where and helps you understand where they think the work is concentrated.

Understand the experience level of who will be doing the work. A senior auditor charges more but is faster and finds fewer gaps than a junior auditor. That's sometimes worth paying for because you spend less time in back-and-forth remediation. Ask for references from other companies your size and in your industry. Find out whether they hit the quoted timeline and whether costs went over.

Don't pick the cheapest quote. The cheapest auditor might not have expertise in your industry or might find more issues that require remediation, ending up costing you more overall. Look for a firm that knows SOC 2, has relevant industry experience, quotes a reasonable fee, and you trust to be thorough but fair. Once you have a quote, ask whether there's room to negotiate scope or timeline to reduce cost. Pushing the audit timeline back a few months reduces cost if your controls won't be fully operational until then anyway. Narrowing scope to your most important systems and expanding it next year is a valid financial strategy.

Making the Cost Decision

Whether SOC 2 is worth the cost depends on your business. If most of your customers either require SOC 2 or will view it as a strong positive signal and you're losing deals without it, the cost is justified. Calculate the revenue at risk and compare it to total cost. If you're losing $500,000 in annual revenue because you don't have SOC 2, a first-year investment of $150,000 is clearly worth it.

If you're not sure whether your customers care about SOC 2, ask them. You might find that your customers don't actually require it and that the cost isn't justified. Or you might find that a significant portion of your sales conversations are blocked by the lack of SOC 2. That's when you know it's worth doing.

Also consider timing. If you're planning on raising capital, investors ask about SOC 2 during diligence. Getting it done before fundraising saves time and makes the fundraising process smoother. If you're planning on expanding into enterprise sales, SOC 2 is almost certainly going to be required, so it's worth doing before you commit to that go-to-market strategy.

Frequently Asked Questions

What does SOC 2 cost for a 50-person company?
Total first-year cost for a 50-person company with moderate infrastructure complexity is typically $80,000 to $175,000. That breaks down to $30,000 to $70,000 in auditor fees, $40,000 to $75,000 in internal labor (500 to 1,000 hours), and $10,000 to $30,000 in tooling, readiness assessments, and contractor support.

Why is the first year so much more expensive than subsequent years?
Year one requires building the entire compliance foundation: writing policies, implementing controls, establishing evidence collection processes, and training staff. Subsequent years are 30% to 40% cheaper because the auditor is verifying continuity of existing controls rather than evaluating new ones. Annual costs typically stabilize at $60,000 to $150,000.

Is it cheaper to use a boutique auditor or a Big 4 firm?
Boutique compliance firms typically charge 30% to 50% less than Big 4 firms for equivalent SOC 2 engagements. The tradeoff is brand recognition — some enterprise customers specifically ask whether your auditor is a major firm. For most mid-market companies, a reputable boutique firm with SOC 2 specialization provides equivalent audit quality at lower cost.

What is the single biggest cost driver in a SOC 2 audit?
Internal labor. According to ISACA survey data, internal preparation labor accounts for 40% to 60% of total first-year SOC 2 cost — routinely exceeding auditor fees. Organizations that underestimate internal labor by treating it as "free" because no external check is written are the ones most surprised by the true cost.

Can we reduce cost by starting with Type 1 and moving to Type 2 later?
Yes. Type 1 costs $15,000 to $50,000 in auditor fees (roughly 40% to 60% of Type 2) and can be completed in 3 to 4 months. This gives you a credential for immediate sales conversations while you build the evidence base for Type 2. The downside is that you pay for two separate engagements rather than one, so total cumulative cost is higher than going directly to Type 2.

How much should we budget for remediation?
Budget $5,000 to $20,000 for minor remediation (documentation gaps, timing issues with quarterly processes). For significant control failures requiring re-testing, budget $15,000 to $40,000 and an additional 2 to 4 months of timeline. The 2023 Coalfire audit trends report found that 65% of first-time audits have at least one exception requiring remediation.
