Operating profit does not show whether a business can cover loan interest
A business can report a positive operating profit and still have limited room for loan repayments. Operating profit focuses on trading activity before financing costs. A lending cash-flow test must continue below that line.
The Reserve Bank of Australia’s October 2026 Financial Stability Review says the operating-margin measure used for small and medium sized firms excludes interest costs. The RBA also notes that smaller firms and businesses with fewer cash buffers are more vulnerable to cost pressures. These are economy-wide observations, not an assessment of any individual borrower.
Why operating profit is not the end of the repayment test
Revenue less day-to-day operating costs can show whether the underlying business is profitable. Interest expense sits below that operating result, so a positive margin does not by itself show whether the business can comfortably service debt.
Principal repayments also use cash even though principal is not an operating expense in the profit-and-loss calculation. That distinction matters when owners compare an accounting result with the money available in the bank account.
Illustration: follow the cash below operating profit
Assume monthly revenue of $80,000 and operating costs of $68,000, leaving $12,000 operating profit. After $5,000 interest and a $4,000 principal repayment, $3,000 remains before tax, owner drawings and timing differences. The figures are illustrative; the purpose is to show the order of the calculation.
Check interest cover, total debt service and the cash buffer
First, compare the operating result with interest expense. Second, include scheduled principal repayments and other committed cash outflows. Third, test how long accessible cash could absorb higher costs, slower customer receipts or a quieter trading period.
business.gov.au recommends monitoring cash flow by tracking money coming in and going out, preparing forecasts and identifying possible shortfalls. A forecast should be reconciled with current bank statements and financial records rather than treated as a stand-alone estimate.
BV Finance can help review eligible commercial-finance options, repayment structures and the cash-flow effect of a proposed loan. Actual pricing, borrowing capacity and approval remain subject to lender assessment. Accounting and tax treatment should be confirmed with qualified advisers.
