## Formula

Service cost = Direct cost + Shared cost × (Service driver / Total driver); Cost per unit = Service cost / Units delivered

- Service cost = Direct cost + Shared cost × (Service driver / Total driver); Cost per unit = Service cost / Units delivered.
- Inputs used: Currency, Infrastructure billed directly to the service, Shared infrastructure cost to allocate (optional), This service's share of the allocation driver (optional), Total allocation driver across all services (optional), Units the service delivered (optional), Price as of (optional), Price source (optional).
- Edge handling: Infrastructure billed directly to the service is required.; Infrastructure billed directly to the service cannot be negative.; Infrastructure billed directly to the service must be no more than 1000000000000.; Shared infrastructure cost to allocate (optional) is required.; Shared infrastructure cost to allocate (optional) cannot be negative..

## Inputs

- Currency
- Infrastructure billed directly to the service
- Shared infrastructure cost to allocate (optional)
- This service's share of the allocation driver (optional)
- Total allocation driver across all services (optional)
- Units the service delivered (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: A service with direct spend plus a share of shared platform cost

Shared cost is split by the driver you chose and entered, never by a default rule.
1. Start with Currency: USD, Infrastructure billed directly to the service: 18400, Shared infrastructure cost to allocate (optional): 42000, This service's share of the allocation driver (optional): 1300, Total allocation driver across all services (optional): 9800, Units the service delivered (optional): 0.
2. Apply the method: Service cost = Direct cost + Shared cost × (Service driver / Total driver); Cost per unit = Service cost / Units delivered.
3. Shared cost is split by the driver you chose and entered, never by a default rule.

## 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; shared cost is attributed in proportion to an agreed allocation driver. See the source link on this page.

### What kind of calculation is this?

Directly billed cost plus a share of shared cost apportioned by the driver the user chose. 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 underlying monitoring, incident records or change records are complete. A mean over a short period, or over few events, is a weak description of behaviour. The result is only as current as the rates entered; a rate taken months ago is not a current cost. The result is only as good as the driver chosen; a driver unrelated to consumption will misallocate cost.

### How do I use the Infrastructure Cost per Service Calculator?

Enter the required values for Currency, Infrastructure billed directly to the service, Shared infrastructure cost to allocate (optional), This service's share of the allocation driver (optional), Total allocation driver across all services (optional), and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Infrastructure Cost per Service Calculator use?

Service cost = Direct cost + Shared cost × (Service driver / Total driver); Cost per unit = Service cost / Units delivered The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### Can the Infrastructure Cost per Service Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this infrastructure cost per service calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
