Safety Stock Calculator (Excel)

About this template

Compute safety stock for up to 10 SKUs by two methods, statistical and simple, then compare side-by-side. Includes a Z-multiplier lookup table for 7 service levels.

What's included

  • Statistical formula: Safety Stock = Z × σ × √LeadTime
  • Simple formula: (Max Use × Max LT) − (Avg Use × Avg LT)
  • Side-by-side comparison sheet with recommended buffer
  • Built-in Z lookup for 90% to 99.9% service levels
  • Pre-loaded with 10 sample SKUs across categories

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. Departments that carry stock at retail value rather than cost usually track it with a retail inventory method tracking template, which produces the same average-inventory figure this calculator needs.

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.
