Business Calculators

Inventory Analysis Calculator

Measure how efficiently you sell through stock with inventory turnover and days-on-hand — key signals of working-capital health.

Inputs

Cost of goods sold (annual)

Average inventory value

Estimates only. Change any value to recalculate instantly.

Inventory turnover 6.7× you sell through stock about every 55 days

Turnover ratio 6.67× times per year

Days inventory on hand 55 days

Annual COGS $600,000

Average inventory $90,000

A turnover of 6.7× means you cycle through your average inventory that many times a year. Higher turnover frees up cash and reduces holding costs, but too high can signal stockouts and lost sales — the right level depends on your industry.

How this calculator works

This calculator runs entirely in your browser — nothing you enter is sent anywhere, and there is no sign-up. Change any input and the result, breakdown, and schedule update instantly.

Rate and cost fields are pre-filled with current benchmarks (Federal Reserve / Freddie Mac via FRED (St. Louis Fed)), so your first result is already realistic — replace them with your own quote to see your numbers. To weigh one option against another, use the loan comparison calculator.

Common questions

Is this calculator free, and do I need to sign up?

Yes and no — it is completely free and asks for no account or personal details. Every calculation happens in your browser, so nothing you type is stored or sent to us.

How accurate are the results?

The math is exact for the inputs you give it, but the defaults are national benchmarks — your real rate, fees, taxes, and insurance will differ. Treat the result as a close estimate to refine with a real quote.
