Choose financial ratios that fit a service company with little inventory. Calculate margins, receivables days, asset turnover and liquidity from billing and ledger exports, then check what each result means.
Financial ratios for service companies measure how delivery spending becomes profit, how invoices become cash and how much revenue the asset base supports. Focus on margins, receivables, liquidity and asset turnover when inventory is small. Read the figures together: a healthy operating margin does not pay payroll while invoices remain uncollected.
A consulting firm, design agency and facilities contractor can all sell services while carrying very different assets and delivery costs. Select peers by how they earn revenue and fund operations. An equipment-heavy service business needs a different interpretation of asset turnover from a firm whose main resource is its employees' time.
The CFA Institute's financial analysis guidance separates profitability, liquidity and activity ratios and stresses comparisons across periods and businesses. The categories belong together. A single favorable ratio does not establish financial health.
Use the general financial ratios guide for the broader formula set. Here the work is choosing denominators and supporting schedules that fit services. These are professional-service operating companies; regulated banks and insurers require different analysis.
Start with the income statement, opening and closing balance sheets, billed receivables aging and revenue detail. Match the legal entities, currency and fiscal period before computing anything. Reconcile direct delivery payroll, benefits and subcontractor costs to the cost-of-services line under the company's accounting policy.
Keep sales and corporate payroll in operating overhead where that policy places them. Changing which salaries count as delivery costs changes gross margin without changing total operating profit. Document the allocation and repeat it each period.
The following illustrative US consulting company reports a full 365-day fiscal year. All revenue is credit revenue. Billed receivables have no allowance in this simplified example; there is no inventory, no short-term investment balance and no unbilled asset. The opening and closing balance sheets supply the averages.
| Input | Opening balance (USD) | Closing balance or annual amount (USD) |
|---|---|---|
| Annual net service revenue | 2,400,000 | |
| Annual cost of services | 1,500,000 | |
| Annual operating overhead | 540,000 | |
| Billed trade receivables | 240,000 | 360,000 |
| Total assets | 1,100,000 | 1,300,000 |
| Unrestricted cash | 180,000 | |
| Current prepaid expenses | 60,000 | |
| Current liabilities | 300,000 |
Current assets are the closing cash, billed receivables and prepayments: $180,000 + $360,000 + $60,000 = $600,000. Total assets include those current assets and the company's other assets. Amounts are whole dollars.
Gross margin = (Net revenue - Cost of services) / Net revenue
Operating margin = Operating profit / Net revenue
Receivables days = Average billed trade receivables / Credit revenue × Days in period
The CFA Institute ratio list defines the margin ratios and the relationship between receivables turnover and days outstanding. With all sales on credit, the revenue denominator here also equals credit revenue.
| Step | Calculation from the inputs | Result (USD unless shown) |
|---|---|---|
| Gross profit | 2,400,000 - 1,500,000 | 900,000 |
| Gross margin | 900,000 / 2,400,000 | 37.5% |
| Operating profit | 900,000 - 540,000 | 360,000 |
| Operating margin | 360,000 / 2,400,000 | 15.0% |
| Average billed receivables | (240,000 + 360,000) / 2 | 300,000 |
| Receivables turnover | 2,400,000 / 300,000 | 8.0 times |
| Receivables days | 300,000 / 2,400,000 × 365 | 45.6 days |
Percentages, turnover and days are rounded to one decimal. Calculate from the original dollar values rather than rounded intermediate figures.
The controller should prove the income statement identity: $1,500,000 + $540,000 + $360,000 = $2,400,000. Gross profit also equals overhead plus operating profit: $540,000 + $360,000 = $900,000. The revenue and receivables totals must tie to the ledger and aging schedules.
For detailed cost classification, see gross profit margin. For collection analysis by customer, days sales outstanding explains the supporting invoice checks. Average-balance days here will differ from a closing-balance DSO; label the method before comparing reports.
Total asset turnover relates the year's revenue to average assets. The liquidity ratios use balances at the reporting date, so they answer a different question.
| Measure | Calculation | Result (USD unless shown) |
|---|---|---|
| Average total assets | (1,100,000 + 1,300,000) / 2 | 1,200,000 |
| Total asset turnover | 2,400,000 / 1,200,000 | 2.0 times |
| Current ratio | 600,000 / 300,000 | 2.0 times |
| Quick ratio | (180,000 + 360,000) / 300,000 | 1.8 times |
| Cash ratio | 180,000 / 300,000 | 0.6 times |
The quick ratio leaves out the $60,000 prepaid expense because it does not become cash available for paying obligations. Even the receivables included in quick assets still need collection. The cash ratio shows the narrower amount already available relative to current liabilities.
Asset turnover is useful for the company's trend, but leasing, acquisitions and goodwill can change its denominator. Compare like accounting policies and use monthly average balances when seasonality makes a simple opening-and-closing average unrepresentative.
Finance owns the definitions and reconciliations. Delivery leaders explain margin movement through staffing, subcontracting, scope and pricing. Billing and credit teams explain overdue invoices and the interval between completed work and an approved bill. Treasury uses dated receipts and payroll obligations to assess the cash need.
Use financial ratios by industry when selecting a comparison group; a broad services label alone is not a benchmark.

Start with margins, receivables days, liquidity and asset turnover. Together they show whether services earn enough, invoices turn into cash and resources support revenue. Add debt coverage where borrowing is material, and use operating measures such as utilization to investigate the financial results.
It usually adds little when inventory is immaterial or absent. Do not manufacture a turnover figure using a zero balance. A service company that resells equipment or holds meaningful supplies can analyze that activity separately from its labor-based service operations.
Keep billed receivables days separate from unbilled work unless you explicitly define a combined measure. Billed receivables track customer collection, while unbilled amounts may depend on milestone approval or invoicing. Combining them can hide whether the delay occurs before or after billing.
