> The operating asset turnover calculator measures how efficiently a company uses the assets it needs to run its business – cash, receivables, inventory, prepaid expenses and fixed assets – to generate sales.

## Inputs

- Cash
- Accounts receivable
- Inventory
- Prepaid expenses
- Fixed assets (net)
- Sales

## Results

- Operating assets
- Operating asset turnover
- Days of sales tied up in operating assets

## Formula

```
Operating assets = cash + accounts receivable + inventory + prepaid expenses + fixed assets
Operating asset turnover = sales ÷ operating assets
```

## Explanation

Unlike total asset turnover, this ratio excludes non-operating assets such as investments, so it focuses on the core business. A higher turnover means more sales from each dollar of operating assets.

### How to use the Operating Asset Turnover Calculator

- **Cash**
- **Accounts receivable**
- **Inventory**
- **Prepaid expenses**
- **Fixed assets (net)**
- **Sales**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the operating assets from the balance sheet and sales for the year.

### Tips

- Use figures for the same period (a month, a quarter or a year) for every input so ratios compare like with like.
- Track the metric over time – the trend usually tells you more than a single value.
- Compare your result with industry benchmarks, which vary a lot between sectors.
- Treat the result as a starting point for a decision, then check the assumptions behind each input.

### Common mistakes to avoid

- Mixing monthly and yearly numbers in the same calculation.
- Using revenue where the formula needs profit (or the other way round).
- Forgetting hidden costs such as taxes, fees, overheads or your own time.

### What each result means

- **Operating assets** = [Cash] + [Accounts receivable] + [Inventory] + [Prepaid expenses] + [Fixed assets (net)]
- **Operating asset turnover** = [Sales]÷[Operating assets]
- **Days of sales tied up in operating assets** = [Operating assets]÷[Sales]×365

### Example values

How the main result changes when **Cash** changes and everything else stays at the example values above:

## Worked example

Inputs — Cash: $50,000; Accounts receivable: $120,000; Inventory: $180,000; Prepaid expenses: $20,000; Fixed assets (net): $630,000; Sales: $2,000,000.

Results — Operating assets = $1,000,000.00; **Operating asset turnover = 2 ×**; Days of sales tied up in operating assets = 183.

## FAQ

**What is a good operating asset turnover?**
Higher is better; compare with peers in the same industry.

**Why exclude investments?**
They don't help generate operating sales, so they would distort the ratio.

**How can a company improve it?**
Faster collections, leaner inventory and better use of equipment.

**What formula does the Operating Asset Turnover Calculator use?**
Operating assets = cash + accounts receivable + inventory + prepaid expenses + fixed assets.
