Financial efficiency ratios connect revenue and cost of goods sold with the assets supporting them. Compare asset, inventory and receivables turnover using reconciled business-unit exports and a worked company total.
Financial efficiency ratios measure how quickly assets, inventory and receivables support a company's sales. The core activity measures are total asset turnover, inventory turnover and receivables turnover. Calculate them from matched periods and average balances, then investigate the operating reasons behind the differences.
Efficiency is a family of measures rather than one universal score. The CFA Institute's financial analysis guidance classifies inventory, receivables and asset turnover as activity ratios and distinguishes them from liquidity ratios.
Total asset turnover = net revenue / average total assets.
Inventory turnover = cost of goods sold / average inventory.
Receivables turnover = net credit sales / average trade receivables.
Average balance = (opening balance + closing balance) / 2.
Each result is expressed in times per period. An annual inventory turnover figure uses annual cost of goods sold and an average inventory balance supporting that year. A quarterly figure measures a quarter's activity; do not compare it directly with an annual figure.
Asset turnover measures revenue relative to the entire asset base. Inventory turnover uses cost because inventory is carried at cost, while receivables turnover uses credit sales because cash sales do not create customer receivables. Profitability and liquidity answer different questions; the broader financial ratios guide explains those families.
Use one legal entity or a set of business units that can be added without double counting. The worked example is an illustrative US distributor with East and West units, no interunit sales and a fiscal year ended December 31, 2025.
Bring the income-statement export for the year and balance-sheet exports at its opening and close. Keep unit, account, period, currency and amount. Map revenue accounts to net revenue, product cost accounts to cost of goods sold, and the relevant balance-sheet accounts to assets, inventory and trade receivables.
Credit sales need their own source flag or invoice-register breakdown. Do not assume all revenue was billed on credit. This example uses gross trade receivables consistently; if your company uses receivables net of the allowance instead, label that choice and apply it consistently.
| Unit | Net revenue (USD) | Net credit sales (USD) | Cost of goods sold (USD) |
|---|---|---|---|
| East | 2,400,000 | 2,160,000 | 1,560,000 |
| West | 1,200,000 | 960,000 | 840,000 |
| Company | 3,600,000 | 3,120,000 | 2,400,000 |
Tie revenue and cost totals to the ledger, and tie credit sales to the invoice export. Keep currency consistent; translating only the sales numerator while leaving balances in another currency produces a meaningless ratio.
The opening balance is the preceding December 31 close, and the closing balance is December 31, 2025. The average column uses the opening-plus-closing formula above. All amounts in this table are exact whole dollars.
| Unit and balance | Opening (USD) | Closing (USD) | Average (USD) |
|---|---|---|---|
| East: total assets | 1,000,000 | 1,400,000 | 1,200,000 |
| West: total assets | 900,000 | 1,100,000 | 1,000,000 |
| Company: total assets | 1,900,000 | 2,500,000 | 2,200,000 |
| East: inventory | 240,000 | 280,000 | 260,000 |
| West: inventory | 280,000 | 320,000 | 300,000 |
| Company: inventory | 520,000 | 600,000 | 560,000 |
| East: trade receivables | 180,000 | 252,000 | 216,000 |
| West: trade receivables | 160,000 | 224,000 | 192,000 |
| Company: trade receivables | 340,000 | 476,000 | 408,000 |
For example, East's average inventory is ($240,000 + $280,000) / 2 = $260,000. The company average inventory is $260,000 + $300,000 = $560,000, which also equals ($520,000 + $600,000) / 2. That identity checks the grouping before turnover is calculated.
Opening and closing averages are convenient, but they can miss a large seasonal stock build between those dates. If using monthly balances, document the observation dates and weighting, and use the same convention for both units and every comparison period.
Divide the activity table by the corresponding average balance. Ratios below are rounded to two decimal places; calculations retain the unrounded inputs.
| Unit | Asset turnover calculation | Inventory turnover calculation | Receivables turnover calculation |
|---|---|---|---|
| East | 2,400,000 / 1,200,000 = 2.00 times | 1,560,000 / 260,000 = 6.00 times | 2,160,000 / 216,000 = 10.00 times |
| West | 1,200,000 / 1,000,000 = 1.20 times | 840,000 / 300,000 = 2.80 times | 960,000 / 192,000 = 5.00 times |
| Company | 3,600,000 / 2,200,000 = 1.64 times | 2,400,000 / 560,000 = 4.29 times | 3,120,000 / 408,000 = 7.65 times |
The company asset turnover is not the simple average of 2.00 and 1.20, which would be 1.60. Its proof is the average weighted by assets:
(1,200,000 × 2.00 + 1,000,000 × 1.20) / 2,200,000 = 3,600,000 / 2,200,000 = 1.64 times, rounded.
Inventory turnover needs inventory weights, and receivables turnover needs receivables weights. The guide to count-weighted and value-weighted measures explains why the denominator determines the right weighting.
For the same 365-day year, divide 365 by unrounded turnover to express the latter measures as days. East's inventory days are 365 / 6 = 60.8, while West's are 365 / 2.8 = 130.4. Receivables days are 365 / 10 = 36.5 for East and 365 / 5 = 73.0 for West, rounded to one decimal place. Keep those average-balance definitions visible when comparing another report's days measures.
West holds more average inventory than East despite lower cost of goods sold. Operations should inspect aging stock, product availability and order sizes before deciding whether to reduce purchases. The detailed inventory turnover guide owns the inventory-specific calculation and interpretation.
West also collects more slowly relative to credit sales. Credit control should check payment terms, disputed invoices and the aging distribution rather than infer that every customer is late. Use the receivables turnover guide for that measure's narrower treatment.
FP&A owns the cross-unit comparison, accounting owns reconciled inputs and policy consistency, and operating owners explain what changed. A ratio establishes a question; it does not authorize a stock reduction, tighter customer terms or an asset disposal by itself.
Bring a financial workbook or Google Sheet containing revenue, credit sales, costs and opening and closing balances by business unit. Covirage maps the columns; its tools compute and check the ratios, and the external AI model explains the movements with every figure traced to its rows. Create a free Covirage account, which takes about a minute, then set up your business and bring a sample of your own data.

Higher turnover generally means more activity per dollar invested, but context matters. Very high inventory turnover can accompany stockouts, and asset turnover can rise after outsourcing. Check service levels, margins and capacity before treating a higher ratio as an improvement.
Sales and costs accumulate throughout a period, while balance-sheet amounts describe a point in time. Average balances better match the resources supporting that activity. Opening and closing balances are a practical starting point; seasonal businesses may need consistently calculated monthly averages.
Efficiency ratios measure the relationship between activity and the resources supporting it. Liquidity ratios compare resources available to meet short-term obligations. A business can turn inventory quickly while still lacking enough cash to cover a payment due immediately.
A simple average usually gives the wrong company result because units have different balance sizes. Sum the relevant activity and divide by the summed average balances. If using a weighted average, weight each unit by its denominator for that specific ratio.
