Why this page exists

Inventory performance is easier to read when sold units, unsold units, and sell-through percentage are shown together. This calculator helps visitors estimate sell-through rate from units received and units sold during a period, while also keeping the leftover count visible.

Sell-through rate calculator

Estimate sell-through rate and unsold units from units received and units sold during a period.

Result

80.00%

Estimated sell-through rate based on units sold compared with units received during the period entered.

Sell-through rate80.00%

Unsold units180

Units received900

Units sold720

720 units sold out of 900 received works out to about 80.00% sell-through.
That leaves about 180 units unsold from the units received in this estimate.
Sell-through is most useful when receipts and sales are measured over the same period and against a consistent inventory definition.

This is a simple inventory metric. Beginning inventory, transfers, returns, and mismatched time periods can all change how the result should be interpreted.

How it works

What the calculator is doing

Enter units received and units sold for the period you want to review.

The calculator divides units sold by units received to estimate sell-through rate.

It also shows the unsold portion of the received units, while flagging results above 100% that may reflect beginning inventory or mismatched periods.

Understanding your result

Sell-through is most useful when receipts and sales are measured over the same period and against a consistent inventory definition. If sold units exceed units received, the result may still be real, but it usually points to beginning inventory or timing differences.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Check how quickly new inventory is moving

A simple sell-through percentage can make product movement easier to compare across periods or categories.

Pair sold units with unsold inventory

Seeing the leftover count next to the rate can make replenishment planning more concrete.

Spot unusual rates above 100%

A high result can be a useful signal to double-check timing or beginning inventory assumptions.

FAQ

Common questions

How is sell-through rate calculated?

The calculator divides units sold by units received and multiplies by 100 to show a sell-through percentage.

What does it mean if sell-through is over 100%?

It often means beginning inventory, transfers, or mismatched periods are affecting the comparison between units sold and units received.

Why show unsold units too?

Because the leftover unit count adds context that a percentage alone can miss when you are planning inventory actions.
