> The sell-through rate calculator works out the percentage of inventory received that was sold during a period, a key retail measure of how well products move off the shelf.

## Inputs

- Units received (or beginning inventory)
- Units sold

## Results

- Sell-through rate
- Units left
- Rating

## Formula

```
Sell-through rate = units sold ÷ units received × 100
```

## Explanation

A high sell-through means you ordered the right amount; a low one means excess stock that may need markdowns. Fashion retailers often aim for 60–80% over a season; grocery items need much higher rates because they spoil.

### How to use the Sell-Through Rate Calculator

- **Units received (or beginning inventory)**
- **Units sold**

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

### How it works

Enter the number of units received (beginning inventory plus deliveries) and the units sold in the period.

### 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

- **Sell-through rate** = [Units sold]÷[Units received (or beginning inventory)]×100
- **Units left** = [Units received (or beginning inventory)] - [Units sold]

### Example values

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

## Worked example

Inputs — Units received (or beginning inventory): 1,200; Units sold: 780.

Results — **Sell-through rate = 65 %**; Units left = 420; Rating = Healthy.

## FAQ

**What is a good sell-through rate?**

Sell-through is a percentage of stock sold in a period; turnover counts how many times stock is replaced.

Sell-through rate = units sold ÷ units received × 100.
