Inventory operations toolkit
Turn your stock count, sales pace, costs, and lead time into a clear inventory operations summary — calculated locally in your browser.
The planner estimates daily demand from your monthly average, then multiplies it by supplier lead time and adds a safety-stock buffer for the reorder point. It values current stock at cost, estimates coverage at the current sales pace, and annualizes unit sales to estimate turnover.
With 300 units on hand, 150 average monthly sales, a 14-day lead time, and 7 days of safety stock, daily demand is 5 units and the estimated reorder point is 105 units. At a unit cost of 20, the stock value is 6,000.
It is the estimated stock level at which a new order should be considered, based on lead-time demand and safety stock.
The planner divides average monthly unit sales by 30 for a simple planning estimate.
It is a buffer of inventory intended to protect against demand variation or replenishment delays.
Annualized unit sales are divided by average inventory units.

It estimates how long current units on hand might last at the entered average monthly sales rate.
