Hong Life CalculatorsUnderstanding the accrual ratio calculator — concept and principle
This calculator measures how much of reported earnings is not backed by cash: operating accruals from balance-sheet changes, scaled by total assets, plus a broader ratio based on net operating assets (NOA). Analysts use it as a quick earnings-quality test.
How it is calculated
- Change in non-cash working capital = (ΔCurrent assets − ΔCash) − (ΔCurrent liabilities − ΔShort-term debt − ΔIncome taxes payable)
- Operating accruals = change in non-cash working capital − depreciation and amortization
- Accrual ratio = operating accruals ÷ total assets at the start × 100 (also shown ÷ average total assets)
- Balance-sheet accrual ratio = (NOA end − NOA start) ÷ average NOA × 100
Each change is end of year minus start of year; enter a negative number if an item fell. Set both NOA inputs to 0 to skip the NOA version.
The principle
Earnings equal cash flow plus accruals, which arise when revenue is booked before cash arrives or inventory builds up. Accruals reverse over time and involve judgement, and research has linked high accruals to weaker future earnings. Cash, short-term debt and taxes payable are removed as non-operating; depreciation is a non-cash expense. The NOA version also captures long-term operating assets, so it is usually larger.
Worked example
Defaults: ΔCA 180,000; ΔCash 30,000; ΔCL 90,000; ΔShort-term debt 20,000; ΔTaxes payable 5,000; depreciation 60,000; total assets 4,600,000 then 5,000,000; NOA 2,950,000 then 3,200,000.
- Working capital change = (180,000 − 30,000) − (90,000 − 20,000 − 5,000) = 150,000 − 65,000 = $85,000.
- Operating accruals = 85,000 − 60,000 = $25,000.
- Ratio on start assets = 25,000 ÷ 4,600,000 × 100 = 0.54%.
- Ratio on average assets = 25,000 ÷ 4,800,000 × 100 = 0.52%.
- ΔNOA = 3,200,000 − 2,950,000 = $250,000; ÷ 3,075,000 × 100 = 8.1%.
| Change in current assets during the year | Accrual ratio (÷ total assets at the start) |
|---|---|
| 45,000 | -2.39% |
| 90,000 | -1.41% |
| 135,000 | -0.43% |
| 180,000 | 0.54% |
| 225,000 | 1.52% |
| 270,000 | 2.5% |
| 360,000 | 4.46% |
How to read the result
Near zero or negative means earnings are matched by cash. A high positive ratio means profits run ahead of cash, often because receivables or inventory grow faster than sales: a reason to read the notes, not proof of a problem. Compare with the firm's history and peers.
Common mistakes
- Entering levels instead of changes for the balance-sheet items.
- Forgetting the sign: a fall in current assets is a negative change.
- Leaving cash inside current assets, which mixes cash with accruals.
Frequently asked questions
What is a good accrual ratio?
There is no universal cut-off. Lower is generally read as higher earnings quality; judge it against the company's history and industry peers.
Where do I get net operating assets?
NOA is operating assets minus operating liabilities; the net operating assets calculator computes it.
Why subtract short-term debt and taxes payable?
They are financing and tax items, not operating accruals, so the standard formula removes them from current liabilities.
