Auditors in 2026 cannot simply depend on past financial information they must figure out the story behind the numbers. Financial modelling equips auditors to:
Segment financial performance
Identify the key drivers of the business
Check the results against the assumptions
Identify business inefficiencies
Confirm the accuracy of management’s estimates
An auditor with financial modelling skills can more clearly see the flow of earnings, costs, profits, and cash, and thus make more precise audit judgments.

Budget plans
Sales forecasts
Capital expenditure schedules

Fair value assessments
By financial modelling, auditors can reproduce or challenge the forecast of management by questioning:
Is the assumption credible?
Are the predictions in line with the market?
What if the market changes?
Is the company’s plan for the future reasonable?
