## Formula

C = (N x tin / 1,000,000) x Rin + (N x tout / 1,000,000) x Rout + Other

- C = (N x tin / 1,000,000) x Rin + (N x tout / 1,000,000) x Rout + Other.
- Inputs used: Currency, Items in the batch, Input tokens per item, Output tokens per item (optional), Batch price per million input tokens, Batch price per million output tokens (optional), Other charges (optional), Price as of (optional), and other shown inputs.
- Edge handling: Items in the batch is required.; Items in the batch cannot be negative.; Items in the batch must be no more than 1000000000000.; Input tokens per item is required.; Input tokens per item cannot be negative..

## Inputs

- Currency
- Items in the batch
- Input tokens per item
- Output tokens per item (optional)
- Batch price per million input tokens
- Batch price per million output tokens (optional)
- Other charges (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: 1.2 million items at 800 tokens each, at the batch price you were quoted

The batch price is the one on your own bill; no discount is assumed.
1. Start with Currency: USD, Items in the batch: 1200000, Input tokens per item: 800, Output tokens per item (optional): 120, Batch price per million input tokens: 1.25, Batch price per million output tokens (optional): 5.
2. Apply the method: C = (N x tin / 1,000,000) x Rin + (N x tout / 1,000,000) x Rout + Other.
3. The batch price is the one on your own bill; no discount is assumed.

## 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?

Item count multiplied by the tokens each item uses and the batch prices the user entered. 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. Items that fail and are resubmitted are only counted if the user counted them. Queue time and completion deadlines are not modelled.

### How do I use the Batch Inference Cost Calculator?

Enter the required values for Currency, Items in the batch, Input tokens per item, Output tokens per item (optional), Batch price per million input tokens, 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 Batch Inference Cost Calculator use?

C = (N x tin / 1,000,000) x Rin + (N x tout / 1,000,000) x Rout + Other 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 Batch Inference 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 batch inference cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
