Inventory & Stock Calculators: Reorder Point, EOQ, Safety Stock and GMROI

Running out of stock loses sales and ranking; too much stock locks up cash. These 8 calculators find the balance: when to reorder (daily sales × lead time + safety stock), how much to order (EOQ), what a stockout costs, which stock is dead, how fast inventory turns and how much gross margin each rupee of stock earns (GMROI).

Frequently asked questions

How do I calculate the reorder point?

Average daily sales × supplier lead time in days, plus safety stock. Selling 20 a day with a 10-day lead time and 60 units of safety stock gives a reorder point of 260.

What is EOQ?

The Economic Order Quantity: the order size that keeps ordering cost plus holding cost lowest, √(2 × annual demand × cost per order ÷ holding cost per unit).

What is a good inventory turnover?

It depends on the category. Fast-moving fashion and FMCG often turn 6–12 times a year; slower categories turn 3–4 times.
