METHOD & GUIDANCE
How this calculation works
Keep every input on the same time basis—for example, one month or one financial year—and do not mix cash figures with accrual figures. Tool IQ recalculates every output immediately; nothing you enter is saved or sent to us.
How to use the result
Compare turnover by product line and across consistent periods; a blended company figure can hide slow-moving inventory.
Worked example
Opening inventory of 30,000 and closing inventory of 50,000 average 40,000. With 240,000 COGS, inventory turns six times.
Common mistakes
- Using sales revenue instead of cost of goods sold.
- Using only the closing balance in a seasonal business.
- Assuming a higher turnover is always better despite stockout risk.
Frequently asked questions
Is the inventory turnover calculator free?
Yes. It requires no account and stores no calculation inputs.
Can I use the answer for a formal filing?
No. It is a planning estimate, not accounting, tax, legal or investment advice. Confirm material decisions with a qualified professional.
Which period should I use?
Keep every input on the same basis—for example, one month or one financial year. Use current figures first, then save a cautious scenario for comparison.
