The warehouse maths you keep rebuilding in Excel.
Fill rate, safety stock, truck loading, racking capacity, EOQ, ABC–XYZ. Built by someone who has run warehouses for twenty-five years, not by someone who read about them. Every calculation happens on your device.
Twelve tools that answer a real question
Not thirty generic gadgets. Each one solves a problem a warehouse or planning team actually hits, shows the formula it used, and exports the result.
Fill Rate Calculator
Line fill, unit fill and order fill side by side — the three numbers most teams confuse with each other.
Free toolSafety Stock & Reorder Point
Service-level driven safety stock with both demand and lead-time variability, plus the reorder point.
Free toolPallet & Truck Load Planner
Pallets per truck by both orientations, with a diagram and a clear call on whether volume or weight binds.
Free toolEOQ Calculator
Economic order quantity with the full total-cost curve, so you can see how flat the optimum really is.
Free toolABC–XYZ Classifier
Paste your SKU data, get a nine-box classification by value and demand volatility. Nothing is uploaded.
Free toolWarehouse Space & Racking
Pallet positions from floor area across selective, double-deep, drive-in and VNA configurations.
Free toolInventory Turns & DOH
Turns, days on hand and the working capital tied up in stock — with a benchmark by industry.
Free toolCycle Count Sample Size
Statistically defensible sample size with finite population correction — not a guess at 10%.
Free toolFreight Cost Comparator
Chargeable weight and cost per kg across modes, so air vs road vs rail is an actual comparison.
Free toolManpower & Productivity
Headcount required from volume, productivity standards and shift pattern — with absenteeism built in.
Free toolOTIF & Dock-to-Stock
On-time and in-full split apart, because the combined number hides which half is broken.
Free toolLanded Cost Calculator
FOB to landed, with GST shown separately as creditable rather than buried in the cost.
Free toolYour numbers stay yours
Every calculator is plain JavaScript running in your browser. Nothing is uploaded, logged or stored on a server — because you shouldn't have to paste your stock data into a stranger's website to work out a reorder point.
The formula, written out
Each result shows the formula with your own numbers substituted in. Check it, argue with it, paste it into a review deck. A black box you can't verify is no use in front of a management team.
Built from the floor up
The defaults, the warnings and the “common mistakes” notes come from twenty-five years of running spare-parts and distribution warehouses in India — including the mistakes made along the way.
How the numbers actually behave
Short, practical write-ups on the metrics that get argued about in every warehouse review.
15 warehouse KPIs that actually matter
Most KPI lists have forty metrics and no priority. This one has fifteen, in the order they should be fixed.
GuideRaising fill rate without buying more stock
The five levers that actually move fill rate, in the order they should be pulled — and why stock is the last of them.
GuideSafety stock, explained properly
Why the simple formula quietly under-stocks you, and when lead-time variability matters more than demand variability.
