How the Sell-Through Rate Calculator works
Sell-through measures how much of what you bought actually sold in a period. It is the fastest signal that a buying decision was wrong, and it arrives early enough to act on — well before the stock becomes a markdown problem.

Frequently asked questions
How is sell-through rate calculated?
(Units sold ÷ units received) × 100 over a period. Receiving 500 and selling 350 in a month is a 70% sell-through.
What is a good sell-through rate?
For monthly retail, 70-80% is generally healthy. Below 50% suggests you over-bought or mispriced. Above 90% may mean you under-bought and left sales on the table — very high sell-through is not automatically good news.
When should I mark down based on sell-through?
When the rate implies stock will outlive its selling window. If a seasonal item is at 30% sell-through halfway through its season, waiting rarely helps — the earlier markdown usually recovers more than the later one.
How does it differ from turnover?
Sell-through measures a specific batch against what was received. Turnover measures the whole inventory against sales over time. Sell-through is a buying scorecard; turnover is an efficiency measure.
