Analytical Procedures in Auditing
Analytical Procedures Framework for Audit Testing and Risk Assessment · Also known as: Analytical Review, Ratio Analysis, Trend Analysis
Analytical procedures are evaluations of financial information made by studying plausible relationships among both financial and non-financial data. Rather than testing individual transactions, auditors develop expectations about what numbers should be and compare them to actual results, investigating significant differences. This approach is both required during audit planning and is often more cost-effective than detailed transaction testing.

When to use it
Analytical procedures are required during audit planning and must be performed again during final review. They are particularly effective when account balances are expected to follow predictable relationships (e.g., revenue-based accounts, production costs). Use when testing large account balances where detailed testing is impractical, during preliminary risk assessment, and to identify anomalies warranting deeper investigation. Less useful when business is highly volatile or in early-stage companies without historical patterns.
Strengths & limitations
- Cost-effective compared to detailed transaction testing, especially for high-volume accounts
- Identifies unexpected patterns and anomalies that might be missed by transaction-level testing
- Provides a macro-level view of financial statement reasonableness
- Particularly effective at detecting unusual or fraudulent transactions that disrupt normal relationships
- Depends on the availability of reliable historical data and stable business relationships
- May not detect misstatements that do not disturb account relationships (e.g., systematic overstatement of both sales and receivables)
- False-positive rate can be high if expectations are poorly developed
- Less effective in highly volatile industries or during significant business changes
Frequently asked
What is a 'significant' difference that I need to investigate?
Auditing standards suggest investigating differences that are quantitatively or qualitatively significant. Typically, differences greater than 5-10% of account balance warrant investigation, though materiality and risk should guide judgment.
Can I rely solely on analytical procedures for substantive testing?
Generally no. While analytical procedures are effective audit procedures, they should be supplemented with other evidence such as confirmations, inspections, or detailed testing, especially for material accounts.
What data should I use to develop expectations?
Use prior-period financial statements, industry benchmarks, business plans and budgets, operational data (units sold, production volumes), and non-financial indicators relevant to the account.
How do I document my analytical procedures?
Document the procedure performed, the expectations developed, the actual results, the difference, management's explanation, and your assessment of the explanation's reasonableness. Show your calculations.
