What reorder point means

Reorder point is the stock threshold where replenishment should begin.

The tool combines lead-time demand with safety stock, then compares it with on-hand and on-order stock.

How to read it

A positive reorder gap means current and incoming stock do not cover the target threshold. Days of cover estimates how long available stock lasts.

The goal is not only to produce a number, but to make the result understandable for practical decisions.

Calculation logic and formula interpretation

The tool combines entered values through explicit mathematical rules to generate intermediate values and a final result.

A mathematically correct output does not automatically guarantee legal, tax, or engineering compliance.

How should the output be read?

The displayed value reflects the scenario defined by your selected inputs and assumptions.

Use the result together with risk, timing, cost, and alternative scenario analysis before final decisions.

Real-world example usage

Running two different input sets helps reveal which variable drives the result the most.

That comparison pattern improves planning quality and reduces early-stage estimation errors.

Why this is needed and known limitations

This kind of tool is useful for budgeting, quoting, pre-analysis, and communication clarity.

It should not replace professional review or official compliance checks for final high-impact decisions.
