Healthy retail rotation
$960k COGS, inventory tapering down through the year
A baseline case where inventory turns well and still leaves room for a lead-time buffer.
Result: A solid turnover ratio with inventory days staying in a manageable band
Slow-moving stock
Heavy average inventory against lighter annual COGS
Useful when cash feels trapped on shelves and you need to quantify how slow the system really is.
Result: Days on hand swell quickly once turnover slips, even before stockouts are an issue
Lean reorder cadence
Fast-moving catalog with tighter inventory discipline
A cleaner case for businesses optimizing working capital without going so lean that lead time becomes risky.
Result: Higher turnover lowers days on hand and compresses working-capital drag
