See what share of a batch has actually sold, how much stock is left, and — at your recent pace — how many weeks that stock will last. The formula is exact; the units received, units sold and weekly pace are your own numbers, so nothing here is invented.
⚠️ The formula is exact; the figures are yours. Sell-through = units sold ÷ units received × 100, and the arithmetic carries no error margin — but Kiwi Giyim doesn't pre-fill your numbers. Units received, units sold and your weekly pace come from your own sales and receiving records, so nothing here is an invented figure. Sell-through is always read over a time window, so measure the sold units across a defined period (week, month or season).
Sell-through is the share of a batch that's moved: units sold ÷ units received. Track it over a fixed window — a week, a month, a season — because the same 70% means very different things at different speeds.
Remaining stock is simply received minus sold — the pieces still on hand. It's the figure that feeds weeks of supply and, ultimately, the reorder decision.
Add your average weekly sales and the tool divides remaining stock by that pace to show how many weeks the stock lasts — the early-warning number that says how soon you'll run dry.
A high sell-through is a reorder signal, but each reorder of a colourway is at least 250 pieces at Kiwi Giyim — so plan the cash for a full 250-piece run, not a trickle.
No black box. The calculator runs exactly these lines:
Sell-through % = units sold ÷ units received × 100 Remaining stock = units received − units sold Weeks of supply = remaining stock ÷ average weekly sales Rule: units sold can't exceed units received in one batch The arithmetic is exact — no error margin. Worked example: a 300-piece batch with 210 sold gives 210 ÷ 300 × 100 = 70% sell-through and 90 pieces remaining; at 20 a week that's 90 ÷ 20 = 4.5 weeks of supply. The only numbers that need real values are yours — sold and received from your own reports, and the weekly pace from your recent sales.

Sell-through rate = units sold ÷ units received × 100, always measured over a time window such as a week, a month or a season. For example, if a batch of 300 pieces has sold 210 over the period, the sell-through is 210 ÷ 300 × 100 = 70%, and remaining stock is 300 − 210 = 90 pieces. Both numbers come from your own sales and receiving data — this tool does the exact arithmetic and never assumes a figure.
There is no single correct number, because sell-through only means something against a period and a channel — a 70% sell-through in four weeks is very different from 70% across a whole season, and full-price sell-through reads differently from a clearance figure. Rather than chase a benchmark, use the rate as a signal: a fast, high sell-through early in a style's life points to a reorder, while a slow rate flags markdown or overbuy risk. We don't publish invented industry averages here.
A high sell-through with weeks still left in the season is the classic reorder signal — the style is proven and you risk stocking out before demand cools. Pair the rate with weeks of supply (remaining stock ÷ average weekly sales) to see how long current stock lasts, then use our reorder point calculator to fix the exact on-hand level that should trigger the order. Remember Kiwi Giyim's minimum is 250 pieces per colour, per size, so each reorder of a colourway is a full 250-piece run.
Weeks of supply (also called weeks of cover) is remaining stock ÷ average weekly sales — how many weeks your current on-hand quantity will last if it keeps selling at the recent pace. With 90 pieces left and 20 selling a week, that is 90 ÷ 20 = 4.5 weeks. It's an optional input here: leave the weekly figure blank and you still get sell-through and remaining stock; add it and you get a forward view of when you'll run dry, which is what tells you how soon to reorder against your lead time.
