Where your computed sell-through falls, with the rough movement story each band tells. These thresholds suit a roughly monthly window — sell-through builds over time, so a rate is only comparable against an equal-length period. Read yours together with the timeframe and your stockout risk.
Sell-through rate
What it typically suggests
Under 40%
Slow — most of the stock is still sitting; suspect overstock, weak demand, or a price or listing problem.
40% – 60%
Moderate — stock is moving but not briskly; watch the trend and consider a nudge on price or promotion.
60% – 80%
Healthy — a strong share sold within the period for many retailers; replenishment is likely warranted.
◀ your result (70.0%)
Over 80%
Very fast — selling out quickly; strong demand, but you may have under-bought and risk missing sales.

What it calculates: Sell-Through Rate, Units Remaining, Daily Sell Rate.
Updated 5 June 2026 · Transparent assumptions
Units sold over units received, for a defined period
Sell-through measures how much of what you bought has sold. A rate of 80% after a month means the buy was well sized; 20% means you bought roughly five times what the market wanted in that window.
That makes it a verdict on the purchasing decision rather than on the product. A good product bought in the wrong quantity produces a poor sell-through, and the lesson is about order size.
60% in a week and 60% in a year are opposite results
A sell-through figure quoted without its period cannot be interpreted. The same 60% is excellent over seven days and alarming over twelve months, which is why the calculator also reports the daily rate.
Fashion and seasonal retail commonly look at weekly sell-through against a target curve; slower categories use monthly. Whichever you choose, compare like with like and never against a benchmark computed on a different window.
Very high is a missed sale; very low is a markdown coming
A rate near 100% early in the period is not unambiguously good — it usually means you under-bought and left demand unserved, and it should trigger a reorder rather than satisfaction.
A low rate early means the markdown is coming whether you act now or later, and acting early recovers more. The mistake is holding full price into the back half of the season hoping the curve corrects.
Receipts timing, returns and stock that never reached the shelf
If stock arrived part way through the period, the denominator includes units that had less time to sell, which depresses the rate for reasons that have nothing to do with demand. Staggered deliveries need the rate computed per delivery.
Returns, damaged units and stock held back in a warehouse also distort it. The remaining-units figure reported alongside is the sanity check: if it does not match what is physically there, the inputs are wrong.

Published the calculator with its formula, worked example, assumptions, limitations and a bespoke guide, and added an automated formula test suite covering it.
Tested units sold over units received as a percentage, with units remaining and the daily rate across the period.
Tested that selling everything received gives one hundred percent, and that remaining units reconcile with the two counts.
