Finished Goods Days of Supply Calculator
Estimate finished-goods inventory requirement from daily demand, replenishment lead time, and safety stock. Use it for cases, pallets, retail packs, bottles, cans, pouches, frozen items, refrigerated goods, or private-label finished goods where service level and shelf life matter.
What this calculator does
- Estimate finished-goods inventory requirement from daily demand, replenishment lead time, and safety stock.
- Use it for cases, pallets, retail packs, bottles, cans, pouches, frozen items, refrigerated goods, or private-label finished goods where service level and shelf life matter.
- Connects finished-goods demand, lead time, and buffer stock.
Formula used
- Finished Goods Days of Supply cycle stock = average finished-goods demand × replenishment or production lead time
- Required finished goods days of supply inventory = cycle stock + finished-goods safety stock
Inputs explained
- Average finished-goods demand: Use daily shipments, forecast demand, customer draw, or production consumption on the same unit basis.
- Replenishment or production lead time: Enter days to produce, release, warehouse, ship, or replenish the finished good.
- Finished-goods safety stock: Add buffer for demand variation, QA holds, customer ordering patterns, transport delays, or service-level targets.
How to use the result
- Use it for S&OP, inventory planning, and customer service review.
- Inventory estimates depend on forecast accuracy, shelf-life dating, FEFO rules, release holds, minimum order quantities, lead time, safety stock policy, storage constraints, and spoilage risk.
Common questions
- What information do I need before using the Finished Goods Days of Supply? Use daily finished-goods demand, replenishment lead time, and safety stock for the same SKU and pack basis.
- What does the result mean? It estimates required inventory and implied days covered.
- When is the result only an estimate? It is an estimate when recipe yield, ingredient potency, moisture loss, overfill behavior, line speed, downtime, sanitation scope, allergen controls, packaging scrap, rework, hold time, shelf-life dating, storage conditions, or cost standards differ from the assumptions entered.
- What decision can I make from the result? Use it to set production schedules, avoid stockouts, manage shelf life, or right-size warehouse inventory.
