Frequently asked questions

Should carts be users or events?

Choose one consistent definition. Unique-user carts differ from repeated cart events, so do not mix numerator and denominator bases.

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.
