About Minimum Order Quantity Impact Calculator

A minimum order quantity above your actual requirement forces excess inventory, and the real cost is the holding cost on the average excess balance. Quantifying it gives you a concrete figure to negotiate against, or to justify paying a small price premium for a smaller MOQ.

Formulas

Excess units

Excess = max(0, MOQ - Actual requirement)

Annual holding cost

Holding cost = Excess value / 2 x Annual holding cost rate %

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation or tax into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How do I negotiate a lower MOQ?

Offer a longer commitment, accept a small unit price premium, or agree a blanket order with scheduled releases so the supplier still gets the batch size.

Is paying a premium for a smaller MOQ worth it?

Compare the premium with the holding cost calculated here. For slow-moving items the premium is usually the cheaper option.
