## Formula

Allocated cost = Shared cost × (This consumer's driver ÷ Total driver) + Direct cost

- Allocated cost = Shared cost × (This consumer's driver ÷ Total driver) + Direct cost.
- Inputs used: Currency, Shared cost to allocate, This team's share of the driver, Total driver across everyone, Direct cost owned by this team (optional), Price as of (optional), Price source (optional).
- Edge handling: Shared cost to allocate is required.; Shared cost to allocate cannot be negative.; Shared cost to allocate must be no more than 1000000000000.; This team's share of the driver is required.; This team's share of the driver cannot be negative..

## Inputs

- Currency
- Shared cost to allocate
- This team's share of the driver
- Total driver across everyone
- Direct cost owned by this team (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: $90,000 shared platform cost split by vCPU-hours

You choose the driver; no allocation rule is imposed.
1. Start with Currency: USD, Shared cost to allocate: 90000, This team's share of the driver: 1800, Total driver across everyone: 12000, Direct cost owned by this team (optional): 0.
2. Apply the method: Allocated cost = Shared cost × (This consumer's driver ÷ Total driver) + Direct cost.
3. You choose the driver; no allocation rule is imposed.

## Common questions

### Where does this formula come from?

FinOps Framework capability: allocation — shared cost is attributed to a consumer in proportion to that consumer's share of an agreed allocation driver. See the source link on this page.

### What kind of calculation is this?

Shared cost is apportioned by the consumer's share of the chosen driver, then any directly owned cost is added. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Shows the split the chosen driver produces; it cannot tell whether that driver is the right one. The result is only as current as the prices entered; a price taken months ago is not a current vendor price. Arithmetic over the figures entered — it cannot tell whether the usage or the rate card behind them is right.

### How do I use the Cloud Cost Allocation Calculator?

Enter the required values for Currency, Shared cost to allocate, This team's share of the driver, Total driver across everyone, Direct cost owned by this team (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 Cloud Cost Allocation Calculator use?

Allocated cost = Shared cost × (This consumer's driver ÷ Total driver) + Direct cost 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 Cloud Cost Allocation 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 cloud cost allocation calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
