Examples
Five turns, leftover frames on the floor
You run a bike shop. On January 8 you pull the 2025 year-end reports in QuickBooks Online: cost of sales is $186,000, inventory was $31,000 on January 1 and $41,000 on December 31, so average inventory is $36,000. Inventory turnover is $186,000 ÷ $36,000, or 5.2 times, meaning the merchandise investment was replaced a little over five times in twelve months. Last year the same math was 8.1, and leftover frames from a bike distributor sat through winter, so the slower turn is cash parked on the floor, not a miscoded bill. Compare 5.2 to your own prior year before you reorder spring frames; do not post a journal labeled inventory turnover.
Sales over a December count is not the ratio
You run a hardware shop. On March 14 you tell your CPA the shop turned 9 times last year because 2025 sales were $270,000 and December 31 inventory was $30,000. That is sales divided by one ending count, not inventory turnover. Cost of sales was $162,000, and average inventory (January 1 $24,000 and December 31 $30,000) was $27,000, so turns are 6. Sales include markup, so they overstate how many times you replaced the investment, and a single year-end count skips the year's average. Recalculate with cost of sales over average inventory before you decide you can carry more SKUs from a hardware supplier.
Why it matters
Inventory turnover is a ratio: how many times you replace the merchandise investment in a stated period, usually twelve months. You compute it from cost of sales divided by average inventory; you do not post an account with this name. You will not journal this most months. You will work it at year-end, when unsold goods are piling up, or when cash feels tight while the floor is full. Neighbor inventory is the stock itself on the balance sheet; inventory valuation is the cost method you use to price that stock. Ignore the ratio and cash can sit in slow goods while the P&L still looks busy. Divide sales by a single ending count and you overstate how often you replaced the investment, because sales include markup and one date is not the year's average. Compare this year to your own prior periods; no rule names a required healthy cutoff.
