## Formula

C = i x (ha + hi) x R + Storage + Fee

- C = i x (ha + hi) x R + Storage + Fee.
- Inputs used: Currency, Price per instance-hour, Instances held, Hours serving traffic, Hours idle but still billed (optional), Model storage cost (optional), Fixed platform fee (optional), Price as of (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.; Instances held is required.; Instances held cannot be negative..

## Inputs

- Currency
- Price per instance-hour
- Instances held
- Hours serving traffic
- Hours idle but still billed (optional)
- Model storage cost (optional)
- Fixed platform fee (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: Two instances up for 600 serving hours and 120 idle hours

Idle time is shown separately because it is billed just the same.
1. Start with Currency: USD, Price per instance-hour: 4.10, Instances held: 2, Hours serving traffic: 600, Hours idle but still billed (optional): 120, Model storage cost (optional): 0.
2. Apply the method: C = i x (ha + hi) x R + Storage + Fee.
3. Idle time is shown separately because it is billed just the same.

## 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?

Instance-hours held, serving and idle, priced at the user's per-instance-hour rate. 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. Autoscaling means the instance count changes through the period; a single count is an average the user has chosen. Per-token charges on a hosted endpoint are not included here — cost those with the inference calculator.

### How do I use the Model Hosting Cost Calculator?

Enter the required values for Currency, Price per instance-hour, Instances held, Hours serving traffic, Hours idle but still billed (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 Model Hosting Cost Calculator use?

C = i x (ha + hi) x R + Storage + Fee 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 Model Hosting 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 model hosting cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
