What is stock-to-sales ratio?

It is average inventory value divided by net sales for the same period.

Is a lower ratio better?

Usually yes, as long as you still have enough stock to support sales.

How is this different from turnover?

Turnover looks at how often stock moves. Stock-to-sales looks at how heavy inventory is relative to the sales pace.

How to use this stock-to-sales ratio calculator

This calculator shows how much stock you are carrying relative to monthly sales. It is a simple way to spot when inventory starts getting too heavy for the sales pace.

Why stock-to-sales matters

If stock rises faster than sales, cash starts getting trapped in inventory.

That can happen even when turnover still looks acceptable on the surface.

How to use the ratio

Watch the ratio over time instead of looking at one month in isolation.

A rising ratio usually means buying is running ahead of demand or slow stock is stacking up.
