## Formula

Compute cost = Price per instance-hour × Instances × Hours × (1 − Discount)

- Compute cost = Price per instance-hour × Instances × Hours × (1 − Discount).
- Inputs used: Currency, Price per instance-hour, Instances running, Hours in the period, Discount already agreed (optional), Price as of (optional), Price source (optional).
- Edge handling: Price per instance-hour is required.; Price per instance-hour cannot be negative.; Price per instance-hour must be no more than 1000000000.; Instances running is required.; Instances running cannot be negative..

## Inputs

- Currency
- Price per instance-hour
- Instances running
- Hours in the period
- Discount already agreed (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: 12 instances at $0.096 per hour for a 730-hour month

Your own instance price, taken from your bill; nothing is assumed about the provider.
1. Start with Currency: USD, Price per instance-hour: 0.096, Instances running: 12, Hours in the period: 730, Discount already agreed (optional): 0.
2. Apply the method: Compute cost = Price per instance-hour × Instances × Hours × (1 − Discount).
3. Your own instance price, taken from your bill; nothing is assumed about the provider.

## Common questions

### Where does this formula come from?

FinOps Framework capability: workload optimisation — cloud resource cost is the metered quantity of a resource multiplied by the rate on the organisation's own rate card. See the source link on this page.

### What kind of calculation is this?

Instance-hours multiplied by the price the user entered, less any discount already agreed. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

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 Compute Cost Calculator?

Enter the required values for Currency, Price per instance-hour, Instances running, Hours in the period, Discount already agreed (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 Compute Cost Calculator use?

Compute cost = Price per instance-hour × Instances × Hours × (1 − Discount) 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 Compute Cost 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 compute cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
