Inventory Calculators
Reorder points, EOQ and turnover — holding enough stock without drowning in it.
- EOQ Calculator The order size where ordering costs and holding costs balance — buy less and you pay in paperwork, buy more and you pay in warehouse space.
- Reorder Point Calculator The stock level that says "order now" — early enough that the new shipment lands before the shelf goes empty.
- Safety Stock Calculator The buffer that absorbs a hot sales week or a late container — sized from your real worst case, not a guess.
- Inventory Turnover Calculator How many times a year your inventory converts back into cash — the speed metric behind healthy stock levels.
- Days of Inventory Calculator How many days of selling your current stock represents — the countdown clock version of inventory turnover.
- Sell-Through Rate Calculator What share of the stock you brought in actually sold — the fastest verdict on a buy, a season, or a product launch.
- Stock to Sales Ratio Calculator How many dollars of inventory you hold for every dollar of monthly sales — the retail buyer’s early-warning gauge.
- Inventory Holding Cost Calculator The rent your inventory quietly pays every month it sits on the shelf — storage, capital, insurance, and shrinkage combined.
- Dead Stock Cost Calculator Dead stock is not just a write-off waiting to happen — it is frozen cash that keeps charging you rent while it waits.
- Fill Rate Calculator The share of orders you could ship immediately from stock — the customer’s-eye view of how good your inventory planning really is.
- Weeks of Supply Calculator The sell-out countdown for a SKU — the number to check against your supplier’s lead time before every reorder.
- Inventory Shrinkage Calculator The gap between what your system says you own and what the shelf count actually finds — theft, damage, and paperwork errors, priced.
