What is inventory turnover?

It is the number of times inventory turns into cost of goods sold during the period you measured.

Is higher turnover always better?

Not always. It is only better if you can still stay in stock on the items customers want.

Why does the restaurant model use planning ranges?

Restaurant stock behaves differently and is harder to compare cleanly to public retail inventory data.

What this means

Inventory is moving too slowly

Your turnover is below the range we use for restaurant or cafe

At your current pace, inventory turns about 1.71 times in this 30-day period and sits for about 17.5 days on average.

If you move toward 2.2 turns in the same period, you could run the same sales with about $54,545 in stock instead of $70,000.

Benchmarks and planning ranges used in this inventory turnover calculator

This calculator uses a mixed model. Retail and ecommerce use public-style comparison ranges, while restaurants use a planning range because stock moves differently.

The key point is simple: faster turns usually mean less cash trapped in stock, as long as service levels and availability stay strong.

Calculator guide

How to use this inventory turnover calculator

This calculator shows how quickly inventory is turning into sales. It also translates slow turnover into days on hand and tied-up cash.

Why turnover matters

Slow turnover usually means too much cash is sitting in product that is not moving fast enough.

Fast turnover usually means stock is earning its place, but only if service levels stay healthy.

How to act on the result

If turns are weak, look at slow items, buying cadence, and pricing before you simply buy less.

The goal is not empty shelves. The goal is stock that moves at a healthier pace.
