Frequently asked questions

Does COGS belong in operating expenses?

It depends on your reporting definition. Keep the definition consistent rather than assuming one universal expense list.

Should the inputs use the same period?

Yes. Use figures from the same reporting period and accounting definition so balances and flows remain comparable.

Is the result enough for a decision?

No. The metric summarizes a numerical relationship; compare it with company history, industry context, and accounting or operating policies.
