Reorder Point Calculator
Set the trigger level that fires the next PO for an SKU. Reorder point combines expected demand during lead time with a buffer for the weeks that run hot. Get either half wrong and you either stock out or bury cash on the shelf. Outputs are the ROP itself, the lead-time demand behind it, the buffer as a percent of expected demand, and the days of supply that ROP represents at current sales velocity.
Safety Stock Calculator
Size the buffer that keeps shelves stocked when demand spikes or the truck runs late. Enter a target service level, your demand history, and lead time to get the exact number of units to hold above expected demand. No more guessing with "two extra weeks of supply."
Inventory Turnover Calculator
Measure how many times a year your average inventory sells through and gets replaced. The single most consequential operational KPI in retail. It connects buying decisions, warehouse cash, markdown risk, and finance targets into one number. The turn ratio arrives converted into days and weeks of supply, together with the working capital a one-turn improvement would release.
EOQ Calculator
Find the order size that minimizes what you spend keeping an SKU stocked. Small orders push order cost up. Big orders push carrying cost up. EOQ finds the point where the two curves cross so you stop paying more than you have to, and it anchors every reorder point and safety stock decision downstream.
