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. |

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.
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.
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.
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.
It depends on the product and period, but many retailers consider a monthly sell-through in the range of 60 to 80 percent healthy. Very low rates suggest overstock or weak demand, while very high rates can mean you under-bought and lost sales.
Sell-through rate is the percentage of received inventory sold within a set period. It shows how quickly a product moves relative to how much you stocked, making it a quick gauge of demand and buying accuracy.
Sell-through compares units sold to units received over one period, often for a single product. Turnover compares total sales to average inventory over a longer span, usually a year, across the catalogue. They answer related but different questions.
Because sell-through accumulates over time. Seventy percent in 30 days reflects much faster movement than 70 percent in 90 days. Always compare rates over the same length of period, or the comparison is meaningless.
In this calculation it is capped by the stock you received, so it tops out at 100 percent when everything sells. If you sold more than you received in a period, it usually means you were selling from prior stock, which this single-period view does not separate.
No. It uses gross units sold, so returns are not deducted. If returns are significant, your true net sell-through is lower, and you may want to subtract returned units from units sold for a more accurate picture.
