Restaurant scenarioExample 1
Monthly COGS turnover
Begin $8,000, end $6,000 → average $7,000. COGS $28,000 → 4.0 turns and 7.5 days on hand (excellent).
Inventory
Restaurant Inventory Turnover Calculator
Measure how efficiently restaurant inventory turns over using COGS or food usage, average inventory, and days of inventory on hand.
Inventory turnover
Formula
Average Inventory = (Beginning Inventory + Ending Inventory) ÷ 2 Inventory Turnover = COGS (or Food Usage) ÷ Average Inventory Days of Inventory = Period Days ÷ Inventory Turnover
What it means
Average the stock you started and ended with. Divide period usage (COGS or food usage) by that average to get turns. Divide the period length by turns to see how many days of stock you typically hold.
Good to know
- Beginning and ending values use the same costing method (FIFO, weighted average, etc.).
- COGS or food usage covers the same period as the inventory counts.
- Period lengths: weekly 7, monthly 30, quarterly 90, yearly 365 days.
Ideal range
- Does not separate categories (produce vs dry goods) — overall figures can hide slow movers.
- One snapshot pair cannot show mid-period spikes; use consistent count cadence.
Variables
- Average InventoryMean stock value
- Simple average of beginning and ending inventory dollars.
- Inventory TurnoverTurns in the period
- How many times you sold or used through your average stock during the period.
- Days of InventoryDays on hand
- Approximate days of stock at the current turn rate. Lower is usually better for perishables.

- 2Restaurant scenarioExample 2
Weekly food usage
Flat $5,000 stock with $5,000 weekly usage → 1.0 turn and 7 days on hand.

Slow annual turns
Average $20,000 with $80,000 annual COGS → 4.0 turns and ~91 days on hand (critical).
How to use this calculator
Turn two inventory counts and period usage into turnover and days on hand.
Choose COGS or food usage
Use COGS when you have a P&L figure; use food usage when you track beginning + purchases − ending.
Enter beginning and ending inventory
Use the same valuation method for both counts in the period.
Enter COGS or food usage for that period
Match the period length (week, month, quarter, or year).
Read turnover, days on hand, and the benchmark
Faster turns and fewer days on hand usually mean healthier restaurant stock.
What is inventory turnover?
Inventory turnover shows how many times you move through average stock in a period — and how many days that stock typically lasts.
Turns and days on hand
Turnover = usage ÷ average inventory. Days of inventory = period days ÷ turnover. Faster turns usually mean fresher food and less cash on shelves.
Why inventory turnover matters
Slow stock raises spoilage and storage cost. Overly aggressive turns can cause stockouts. The goal is a healthy middle for your concept.
Restaurant inventory benchmarks
Many operators aim for roughly 7–14 days of overall food inventory. Produce turns faster; dry goods and liquor slower. Compare to your own history first.
Formula in plain language
Average your beginning and ending counts. Divide period COGS or food usage by that average. Then convert turns into days using the period length.
Best practices
Habits that keep turnover numbers trustworthy.
Use one costing method
Beginning and ending values must share FIFO, weighted average, or another consistent method.
Match usage to the count period
Weekly counts need weekly usage. Mixing a month of COGS with a week of counts invents false turns.
Review slow categories separately
Overall turns can look fine while produce or specialty items age. Break out high-spoilage groups.
Pair with food cost %
Turnover shows velocity; food cost % shows margin. Use both after each inventory period.
Common mistakes
Errors that distort inventory turnover.
Using purchases instead of usage
Purchases ignore stock still on the shelf. Prefer COGS or beginning + purchases − ending.
Inconsistent count cadence
Irregular snapshots make trends noisy. Count on a fixed weekly or period-end schedule.
Wrong period length
Selecting yearly while entering monthly COGS understates days on hand dramatically.
Ignoring shrink and waste
Turns look healthier when waste is not recorded. Track waste so usage reflects reality.
