1. What is Audit Percentage?

Audit Percentage, also known as sampling rate, represents the proportion of items sampled from a population for auditing purposes. It indicates what percentage of the total population was examined during an audit process.

2. How Does the Calculator Work?

The calculator uses the audit percentage formula:

\[ \text{Audit \%} = \left( \frac{\text{Sample Size}}{\text{Population Size}} \right) \times 100 \]

Where:

\( \text{Sample Size} \) — Number of items selected for audit (unitless)
\( \text{Population Size} \) — Total number of items in the population (unitless)
\( 100 \) — Conversion factor to express result as percentage

Explanation: This simple ratio calculation helps auditors determine the coverage and representativeness of their sample selection.

3. Importance of Audit Percentage Calculation

Details: Calculating audit percentage is crucial for determining sampling adequacy, assessing audit risk, ensuring statistical validity, and providing evidence of audit coverage in compliance reports.

4. Using the Calculator

Tips: Enter sample size and population size as whole numbers. Sample size must be less than or equal to population size, and population size must be greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good audit percentage?
A: The appropriate percentage depends on the audit objective, risk assessment, and materiality. Typically ranges from 5% to 100% based on circumstances.

Q2: Can sample size be larger than population size?
A: No, sample size cannot exceed population size. The calculator validates this constraint to ensure logical input values.

Q3: How does audit percentage relate to confidence level?
A: Higher audit percentages generally provide higher confidence in audit conclusions, but statistical sampling methods consider both percentage and distribution.

Q4: When is 100% audit sampling used?
A: 100% sampling is used for high-risk areas, small populations, or when regulatory requirements mandate complete coverage.

Q5: Are there industry standards for audit percentages?
A: While there are general guidelines, specific percentages vary by industry, audit type, and regulatory requirements. Professional judgment is essential.
