Etsy Inventory Turnover Calculator

Estimate how quickly your Etsy inventory sells and how many days your stock typically lasts based on cost of goods sold and average inventory.

Your Details

Overview

Use this Etsy Inventory Turnover Calculator to estimate how efficiently your shop is moving stock. Enter your cost of goods sold, beginning inventory, ending inventory and period length to see your turnover ratio and average days inventory remains on hand.

How it works

The calculator first finds average inventory by adding beginning and ending inventory and dividing by two. It then divides cost of goods sold by average inventory to estimate inventory turnover. Finally, it divides the number of days in the period by the turnover ratio to estimate how long stock is typically held before sale.

  2. 2Add your beginning inventory value at cost.
  3. 3Add your ending inventory value at cost.
  4. 4Enter the number of days in the period you want to measure.
  5. 5Review your turnover ratio and estimated days in inventory.

Frequently asked questions

What does this Etsy Inventory Turnover Calculator estimate?

It estimates how many times your inventory turns over during a chosen period and roughly how many days your stock stays on hand before it sells.

Should I use sales revenue or cost of goods sold?

Use cost of goods sold, not revenue. Inventory turnover is normally based on inventory cost values so the figures are compared on the same basis.

What is a good inventory turnover ratio for an Etsy shop?

A good ratio depends on your product category, production time, seasonality and how much stock you keep. Higher turnover usually means stock is moving faster, but very high turnover can also suggest understocking.

Why use average inventory instead of ending inventory only?

Average inventory gives a more balanced estimate across the period by smoothing the change between starting and ending stock levels.

Can I use this calculator for handmade made-to-order products?

Yes, but the result is most useful for products you keep in stock. For made-to-order items, turnover may be less meaningful if you carry little finished inventory.

What does days in inventory mean?

Days in inventory estimates the average number of days stock stays in your business before it is sold.
