Inventory management
Inventory turnover ratio is one of the most useful numbers a small business can track, and one of the most ignored. It tells you how quickly your stock sells and turns into cash — and whether you're holding too much of the wrong thing. This guide explains the formula in plain language, works through examples, and shows what a healthy ratio looks like and how to improve it.
Inventory turnover ratio measures how many times you sell and replace your entire stock over a period, usually a year. A turnover of 6 means you sold through your average stock six times in the year. It's a direct read on efficiency: high turnover means stock moves fast and cash isn't trapped; low turnover means goods are sitting on shelves.
The standard formula is:
Inventory turnover ratio = cost of goods sold ÷ average inventory
Average inventory is usually opening stock plus closing stock, divided by two. Using cost of goods sold (rather than sales revenue) keeps both sides of the equation at cost, which gives a truer picture of how stock moves.
Suppose a shop has a cost of goods sold of ₹12,00,000 for the year. Its opening stock was worth ₹1,80,000 and closing stock ₹2,20,000.
The shop turned its stock over six times — roughly once every two months.
There's no universal "good" number — it depends entirely on what you sell. Grocery and FMCG shops often run high turnover of 10 or more because goods move daily. Furniture, electronics, or specialty retailers may sit much lower and still be healthy. The most useful benchmarks are your own trend over time and comparison with similar businesses, not a generic target.
A low and falling ratio usually points to overstocking, slow-moving lines, or weakening demand — cash tied up in goods that aren't selling. But an unusually high ratio isn't automatically good either: it can mean you're holding too little stock and risking stockouts and lost sales. The goal is fast turnover with reliable availability, not turnover at any cost.
Improving turnover comes down to selling stock faster and holding less of the slow stuff:
All of this needs accurate stock data — which is what StockMitra is being built to keep current without manual effort.
Inventory turnover ratio measures how many times a business sells and replaces its stock over a period, usually a year. It is calculated as cost of goods sold divided by average inventory. A higher ratio means stock moves quickly and less cash is tied up; a lower ratio means stock sits longer, which can signal overstocking or slow sales.
Inventory turnover ratio = cost of goods sold ÷ average inventory. Average inventory is usually opening stock plus closing stock divided by two. For example, if cost of goods sold is ₹12,00,000 and average inventory is ₹2,00,000, the turnover ratio is 6, meaning stock turned over six times in the period.
A good ratio depends heavily on the industry. FMCG and grocery shops often see high turnover of 10 or more, while furniture or specialty retailers may have much lower ratios. The right benchmark is your own trend over time and comparison with similar businesses. Rising turnover with healthy availability is generally positive.
Inventory turnover looks backward over a period to measure how many times stock was sold and replaced. Stock cover looks forward, estimating how many days your current stock will last at the current sales rate. Turnover is a performance metric; stock cover is an operational reorder signal. Both are useful and complement each other.
