## Common questions

### Where does this formula come from?

FinOps Framework capability: unit economics — cost per business unit is total cost for a period divided by the units delivered in the same period; a workload's cost is the sum of its metered components charged at the rates the organisation actually pays. See the source link on this page.

### What kind of calculation is this?

A unit cost with the customer as the unit, optionally expressed per month. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the metering, logs or invoices behind them are complete. The result is only as current as the rates entered; a rate taken months ago is not a current price. Tiered, committed-use, cached-input and minimum-spend pricing are not modelled unless the user has already reduced them to the rates entered. An average hides heavy users: a handful of customers often causes most of the cost. It says nothing about what any individual customer costs.
