Find the on-hand stock level that should trigger your next knitwear order — your safety stock plus the demand you'll sell across the whole lead time. The formula is exact; the daily sales, lead time and buffer are yours to enter, and nothing here is invented.
⚠️ The arithmetic is exact; the inputs are yours. The reorder-point and safety-stock formulas are firm — no error margin. But the average daily sales, lead time and buffer are your numbers: they come from your own sales history and your supplier's quoted timeline, so we don't pre-fill invented business data. The values shown are a worked example; replace them with your real figures. This is the simple safety-stock method (buffer expressed as days of cover), not a statistical service-level model.
The reorder point is the on-hand level that says "order now." It tells you when to reorder so stock lands before you run out — how many to buy is set separately by your MOQ.
You keep selling while the batch is knitted and shipped. Multiply your daily sales by the lead-time days so the reorder point holds enough to bridge that entire gap.
Sales spike and suppliers slip. Safety stock — daily sales × your buffer days — is the cushion that keeps you in stock if the batch is late or demand runs hot.
Each reorder of a colourway is at least 250 pieces at Kiwi Giyim. Slow colours reorder less often but in full 250-piece runs, so plan the cash for a whole batch.
No black box. The calculator runs exactly three lines:
Safety stock = average daily sales × safety days Reorder point = average daily sales × lead-time days + safety stock Days of cover at reorder = reorder point ÷ daily sales = lead + buffer Worked example: 10 units a day, a 45-day lead time and a 14-day buffer give safety stock = 10 × 14 = 140 units and a reorder point = 10 × 45 + 140 = 590 units — 59 days of cover. It's exact arithmetic with no error margin. The only numbers that need to be real are yours: daily sales from your history and the lead time from your supplier.

Your reorder point is the on-hand stock level that should trigger your next production order. Reorder point = average daily sales × lead time in days + safety stock, where safety stock = average daily sales × your safety buffer in days. For example, 10 pieces a day with a 45-day lead time and a 14-day buffer gives 140 units of safety stock and a reorder point of 590 units (10 × 45 + 140). When on-hand stock drops to 590, you place the order — so the new goods arrive just as you are running down to your buffer.
Safety stock is the cushion that covers demand while you wait for the next batch, using the simple method safety stock = average daily sales × safety days. The longer and less predictable your lead time, and the more your weekly sales swing, the more buffer days you should hold — a stable repeat style needs less than a new launch. At 10 pieces a day a 14-day buffer is 140 units; raise the buffer days if a stock-out would cost you a season, lower it if you can top up quickly.
The reorder point tells you when to order; it does not set how many to order. Kiwi Giyim's minimum is 250 pieces per colour, per size, so each reorder of a colourway is at least 250 units even if your reorder point is smaller. For a slow-selling colour that means you reorder less often but in larger, MOQ-sized batches, so plan the cash and the shelf space for a full 250-piece run rather than a trickle.
Yes, directly. The reorder point rises by one day of sales for every extra day of lead time, because you must cover everything you will sell before the new batch lands. Knitwear lead times combine sampling (on new styles), bulk knitting and shipping, so ocean freight from Turkey pushes the reorder point higher than air. Use our knitwear lead time estimator to get a realistic lead time, then feed it into this calculator so you reorder early enough to avoid a gap.
