- Inputs used: Currency, Price per instance-hour, Database instances, Hours in the period, Price per GB-month of storage (optional), Storage provisioned (optional), Backup cost (optional), I/O or request charges (optional), and other shown inputs.
- 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.; Database instances is required.; Database instances cannot be negative..

## Inputs

- Currency
- Price per instance-hour
- Database instances
- Hours in the period
- Price per GB-month of storage (optional)
- Storage provisioned (optional)
- Backup cost (optional)

## Worked example: Two database instances for a month

Instance, storage, backup and I/O charges, each entered from your own bill.
1. Start with Currency: USD, Price per instance-hour: 0.29, Database instances: 2, Hours in the period: 730, Price per GB-month of storage (optional): 0, Storage provisioned (optional): 0.
2. Apply the method: Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost.
3. Instance, storage, backup and I/O charges, each entered from your own bill.

## 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?

Each charge line is priced at the rate the user entered; optional lines are excluded when left at zero. 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. Storage is priced for the period entered; it does not model storage growing within it.

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

Enter the required values for Currency, Price per instance-hour, Database instances, Hours in the period, Price per GB-month of storage (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 Database Cost Calculator use?

Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O 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 Database 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 database cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
