Key Points
- Free cash flow equals operating cash flow minus capital expenditure, and a persistently negative figure signals dependence on external financing.
- IAS 7 does not define free cash flow as a line item, so entities and analysts calculate it differently depending on which items they include.
- Capitalising operating costs to shift them from the operating section into investing activities can inflate reported free cash flow by reclassifying the same spend.
- Auditors typically flag free cash flow diverging from reported profit by more than 25% as an analytical procedures trigger worth investigating.
What is Free Cash Flow?
IAS 7 requires the entity to classify cash flows by activity type but never mentions free cash flow by name. The measure is analyst-derived: take operating cash flow per IAS 7.14 and subtract purchases of property, plant and equipment plus intangible asset additions reported in the investing section (IAS 7.16). What remains is the cash available to service debt and pay dividends without raising new capital.
The calculation depends entirely on how the entity classifies borderline items. IAS 7.33 allows interest paid to sit in either operating or financing activities. An entity that classifies interest paid as financing will report higher operating cash flow (and therefore higher free cash flow) than one that leaves it in operating. The auditor verifies consistency with the prior year and tests whether the classification policy is applied correctly. ISA 520.5 requires the auditor to develop expectations for analytical procedures, and a year-on-year swing in free cash flow that traces to a reclassification rather than a change in operations is the kind of anomaly that demands explanation in the working papers.
Free cash flow also links to working capital management. A profitable entity can report negative free cash flow if receivables are growing faster than collections or if a large capital programme is under way. Conversely, an entity cutting maintenance capital expenditure to preserve cash will show strong free cash flow in the short term while building up a deferred spending problem.
Worked example: Fernández Distribución S.L.
Client: Spanish wholesale distribution company, FY2025, revenue €34M, IFRS reporter. The engagement team calculates free cash flow to evaluate whether the entity can meet its upcoming debt repayment without refinancing.
Step 1 — Extract operating cash flow from the indirect method reconciliation
Fernández reports profit before tax of €2.1M. Non-cash adjustments total €2.0M (including depreciation of €1.6M and amortisation of €0.3M, plus a €0.1M increase in the warranty provision). Net working capital movement is positive €0.9M, driven by a €1.2M increase in trade payables and a €0.5M inventory reduction that together more than offset a €0.8M rise in trade receivables. Tax paid is €0.5M. Interest paid of €0.4M is classified as operating under the entity's accounting policy. Operating cash flow totals €4.1M.
Step 2 — Identify capital expenditure in the investing section
Fernández invested €2.8M in a new cold-storage warehouse and €0.3M in a fleet management software licence. Disposal proceeds of €0.1M from old delivery vehicles are an investing inflow. Total capital expenditure (net of disposals) is €3.0M.
Step 3 — Calculate free cash flow
Operating cash flow of €4.1M minus net capital expenditure of €3.0M produces free cash flow of €1.1M.
Step 4 — Assess debt serviceability
Fernández has a term loan instalment of €1.0M due in March 2026 and a dividend payment of €0.5M declared before year-end. Free cash flow of €1.1M covers the loan instalment but not the combined €1.5M obligation. The shortfall of €0.4M will require drawing on the €2.0M undrawn revolving credit facility.
Conclusion: free cash flow of €1.1M is defensible because the operating cash flow reconciles to the income statement and the capital expenditure ties to verified asset additions, but the shortfall against total commitments requires disclosure of the entity's reliance on the revolving facility.
Why it matters in practice
The most common error is treating free cash flow as a standardised metric when the entity has not disclosed its calculation methodology. Because IAS 7 does not define the measure, two entities in the same industry can report different free cash flow figures from identical underlying cash flows depending on whether they include lease payments or net disposal proceeds against purchases. ISA 520.A5 requires the auditor to consider the reliability of data used in analytical procedures, and an unexplained free cash flow figure lifted from management's board pack without verifying its composition fails that test.
Teams frequently overlook the capitalisation boundary. An entity that capitalises development costs under IAS 38.57 shifts expenditure from operating activities (where it would reduce operating cash flow) to investing activities (where it reduces capital expenditure but not the operating subtotal). The net effect inflates both operating cash flow and free cash flow. ISA 240.A46 identifies improper capitalisation as a fraud risk indicator because it simultaneously improves profit and cash flow metrics.
Free cash flow vs. operating cash flow
| Dimension | Free cash flow | Operating cash flow |
|---|---|---|
| What it measures | Cash remaining after maintaining and expanding the asset base | Cash generated from the entity's principal revenue-producing activities before investing |
| IAS 7 status | Not defined; analyst-derived | Defined by IAS 7.14 as a required subtotal on the face of the cash flow statement |
| Capital expenditure | Deducted | Not deducted (capex sits in investing activities) |
| Audit implication | Not audited as a standalone figure unless presented in the financial statements or used in covenant calculations | Audited as a line item; ISA 330.20 requires substantive procedures on material classes of transactions |
| Manipulation risk | Entity capitalises operating costs to inflate both measures simultaneously | Entity delays supplier payments to inflate the figure at period-end |
The distinction matters because operating cash flow can look strong while the entity is under-investing in its asset base. Free cash flow captures whether the entity generates enough cash to both operate and reinvest. An entity with high operating cash flow but consistently negative free cash flow is funding capital expenditure externally, which is sustainable only as long as financing remains available.

Frequently asked questions
How do I calculate free cash flow from an IAS 7 cash flow statement?
Take the operating cash flow subtotal (after interest and tax, as classified by the entity) and subtract capital expenditure on property, plant and equipment plus purchases of intangible assets from the investing section. IAS 7.16 defines investing activities as cash flows from acquiring and disposing of long-term assets. Do not subtract acquisition payments or other non-recurring investing items unless the analysis is intended to capture total cash consumption.
Does free cash flow include lease payments under IFRS 16?
It depends on the entity's classification. Under IFRS 16, the lessee reports the interest portion of lease payments in operating or financing activities per IAS 7.33 and the principal portion in financing activities per IFRS 16.50. Neither portion sits in investing activities, so a standard free cash flow calculation (operating cash flow minus capex) excludes lease principal repayments entirely. Analysts who want a lease-adjusted figure add the principal portion back as a deduction.
When should an auditor challenge a client's free cash flow figure?
Whenever the entity presents free cash flow in board reports or covenant compliance calculations. Because IAS 7 does not define the term, ISA 720.14 requires the auditor to consider whether other information (including non-GAAP measures in the annual report) is materially inconsistent with the financial statements. If the entity's stated free cash flow cannot be reconciled to the audited cash flow statement, the auditor raises the inconsistency with management.
