Estimate compliance audit expenses including auditor daily rates, travel, report preparation, and remediation consulting for regulatory and internal audits.
The Compliance Audit Cost Calculator estimates the total expense of conducting regulatory or internal compliance audits. Costs include auditor daily rates (which vary by expertise and firm size), on-site days, travel expenses, report preparation, and follow-up remediation consulting.
Regular compliance audits are essential for maintaining regulatory standing, identifying gaps before regulators find them, and demonstrating due diligence. However, audit costs can vary significantly based on scope, complexity, industry, and the firm engaged. A small SOC 2 audit might cost $20,000–$50,000, while a comprehensive SOX audit for a large public company can exceed $2 million.
This calculator helps organizations budget for audits by breaking down the major cost components and providing realistic estimates based on audit scope and requirements.

Audit Fees = Auditor Daily Rate × Audit Days Total = Audit Fees + Travel + Report + Remediation Consulting
Result: $41,000 total audit cost
Audit fees: $2,500/day × 10 days = $25,000. Travel: $5,000. Report: $3,000. Remediation: $8,000. Total: $41,000.
SOC 2 Type II audits typically cost $20,000–$80,000. PCI DSS assessments range from $15,000–$100,000+ depending on merchant level. ISO 27001 certification audits cost $10,000–$50,000. SOX compliance audits for public companies range from $200,000–$2,000,000+.
Treat audits as opportunities for improvement, not just compliance checkboxes. Request detailed findings reports with prioritized recommendations, and use remediation consulting to address systemic issues rather than just individual findings.
Allocate 60–70% of audit budget to actual audit fees, 10–15% to travel, 5–10% to report preparation, and 15–25% to remediation. Include a 10% contingency for scope changes or additional testing requirements.
Costs vary widely. Small business audits may cost $5,000–$20,000. Mid-size company audits range from $20,000–$100,000. Large enterprise or SOX audits can cost $500,000–$2,000,000+. The scope, industry, and regulatory framework drive costs.
Daily rates typically cover the auditor's time for on-site fieldwork, interviews, document review, and testing. Rates range from $1,500–$2,000 for junior auditors to $3,000–$5,000+ for senior partners at Big Four firms.
A focused audit (SOC 2, PCI) typically takes 5–15 on-site days. A comprehensive audit (SOX, ISO 27001) may take 20–40+ days. Planning, preparation, and report delivery add additional time beyond fieldwork.
Many audit components can be performed remotely, especially document review and system testing. Remote audits became common during COVID-19 and continue to reduce travel costs. However, some regulatory audits require on-site verification.
Internal audits are conducted by the organization's own audit team or contracted consultants for self-assessment. External audits are performed by independent certified auditors for regulatory compliance, certification, or third-party assurance.
Thorough preparation reduces auditor time. Organized documentation, pre-audit self-assessments, clear process maps, and responsive point-of-contact assignments all help minimize billable hours and avoid audit scope creep.
