Reliable forecasts are essential to financial decision-makers so that they can base their strategic plan and resource allocation. Reviewing financial models can reveal mistakes that can be disastrously expensive in misjudged decision-making and lost opportunities. According to Deloitte, only 32% of CFOs say it’s a good time to take risks, down from 60% last quarter.
The mistakes can be made due to a missing assumption or simply due to a calculation error. It can impair trust and lead to low financial results. That is why stringently assessing financial models and then reviewing them is vital.
Why Rigorous Best Practices for Financial Model Review Matter?
A well-reviewed financial model provides decision-ready numbers and can be easily converted into an audit-ready financial model. This model meets the eye of other stakeholders and bankers as well. Biases or concealed circularities could contaminate the verifier using EBITDA Reconciliation or interfere with the Roll-Forward assumptions and derail the strategy.
Developing best practices for financial model review enhances the model's integrity and provides governance policies, ensuring the reliability of your financial projections.
Top 5 Financial Model Audit Checklist to Improve Accuracy!
To ensure your financial model withstands scrutiny, apply these proven checks that enhance transparency, usability, and model accuracy improvement.
- Error & Circularity Checks: Use Error-Tracing Macros and Circularity Check
Begin by running automated error-tracing macros to identify broken formulas and inconsistencies quickly. Follow with a circularity check to detect unintended iterative loops that can distort results.
- Detect #REF and #VALUE errors.
- Identify circular references causing calculation delays.
- Ensure formulas compute as expected without infinite loops.
- Driver Validation: Reconcile Model Drivers to Working-Capital Roll-Forward
Confirm that your driver-based modelling accurately reflects business realities by reconciling them to working-capital roll-forward schedules. This prevents faulty assumptions from skewing projections. Key actions include:
- Validating revenue and cost drivers
- Aligning assumptions with operational data
- Avoiding over-optimistic or inconsistent inputs
- Sensitivity & Scenario Testing: Utilize Scenario Manager and Stress EPS
Test model resilience by running the sensitivity analysis test and scenario manager tools. Stress test key metrics such as EPS to understand how variations affect outcomes. Benefits include:
- Identifying critical variables impacting forecasts
- Preparing for best-case and worst-case scenarios
- Enhancing confidence in decision-ready forecasts
- Audit Trail & Version Control: Maintain Version Control Log and Error-Check Toggle
Establish rigorous documentation by keeping a version control log to track changes and iterations. Use an error-check toggle to flag discrepancies instantly during reviews. This practice supports:
- Transparent audit trail documentation
- Efficient identification and correction of errors
- Smooth collaboration among model reviewers
- Stakeholder-Friendly Outputs: Generate Board-Pack-Ready Dashboards
Translate complex data into clear, concise dashboards designed for board-pack readiness and lender due diligence reviews. Effective outputs:
- Summarize key findings visually
- Include reconciliation schedules for transparency
- Enhance stakeholder understanding and trust
Common Pitfalls & Tips to Validate Financial Assumptions!
Ignoring a formal model governance policy often results in uncontrolled versioning that leads to confusion, inconsistent updates that cause outdated assumptions, and untracked errors that reduce overall model reliability.
To avoid these issues:
- Use an error toggle to flag problems during reviews instantly
- Adopt strict documentation practices for transparency
- Separate assumptions from formulas by defining clear input sections
- Maintain regular model audits to catch hidden faults early
These steps enhance auditability, simplify updates, and prevent costly mistakes.
The Final Step Toward Model Integrity
By following these best practices, you can significantly reduce the risk of costly errors, enhance model transparency, and build stronger confidence among stakeholders. A reliable financial model doesn’t just support decisions—it drives them with clarity and precision.
