Sell-through rate formula
Divide units sold by units received, then multiply by 100. If 72 of 100 received units sell, the sell-through rate is 72% and 28 units remain unsold within that simple cohort.

Sell-through connects what arrived with what sold. The period and inventory scope matter as much as the percentage.

Choose a clear measurement period
Seven, 30, 60, or 90 days can all be useful when the comparison is consistent. A launch may need a short window; seasonal inventory may need a matched period from the prior year.
03
What is a good sell-through rate?
There is no universal target. Category, margin, seasonality, replenishment speed, markdown risk, and the age of the stock all change what healthy means.

What this calculator does not include
This simple version does not add beginning inventory, returns, transfers, cancellations, or stock adjustments. Treat received units as the defined cohort you want to evaluate.

Sell-through rate formula
Divide units sold by units received, then multiply by 100. If 72 of 100 received units sell, the sell-through rate is 72% and 28 units remain unsold within that simple cohort.
Use the same SKU, channel or location, and date window on both sides of the formula. Mixing a monthly sales count with lifetime receipts creates a percentage that cannot guide a decision.
Choose a clear measurement period
Seven, 30, 60, or 90 days can all be useful when the comparison is consistent. A launch may need a short window; seasonal inventory may need a matched period from the prior year.
Record the dates with the result so your team knows whether the rate describes launch velocity, a promotion, or a normal replenishment cycle.
What is a good sell-through rate?
There is no universal target. Category, margin, seasonality, replenishment speed, markdown risk, and the age of the stock all change what healthy means.
Compare like with like: the same category, period, channel, and lifecycle stage. A high result can still be unhealthy if margin was sacrificed to achieve it.
What this calculator does not include
This simple version does not add beginning inventory, returns, transfers, cancellations, or stock adjustments. Treat received units as the defined cohort you want to evaluate.
For a perpetual inventory system, reconcile the result with movement records before using it for purchasing or financial reporting.
Questions, answered.
How do you calculate sell-through rate?
Divide units sold during the period by units received for that same scope, then multiply the result by 100.
Can sell-through exceed 100%?
Not for a clean received-inventory cohort. A value over 100% usually means the periods or inventory scopes do not match, so this tool flags it.
Is sell-through the same as inventory turnover?
No. Sell-through compares units sold with units received for a period, while turnover typically divides cost of goods sold by average inventory value.
