How this calculator works

The AI Inference Budget Calculator converts request volume and token usage into monthly and annual spend so product teams can size ongoing API costs. Enter requests per day, tokens per request, and cost per million to estimate monthly tokens (m), monthly cost, and annual cost. The calculator updates instantly and adds a comparison table plus chart so you can test the sensitivity of the result before you use it in a decision.

Inputs

Average daily number of model requests.
Average total tokens consumed by one request.
Blended cost per million tokens across the workload.

Outputs

Estimated monthly token volume in millions.
Estimated monthly cost for the inference workload.
Projected annual cost if the same workload stays active.

Assumptions

A flat blended token cost is used across all requests.
Daily request volume is assumed to stay stable through the month.

Tips

Use a weighted average token cost if your workload mixes several models.
Budget for peaks separately if traffic is highly uneven.

Formula guide

2 formulas

Monthly Tokens = Requests per Day × Tokens per Request × 30 ÷ 1,000,000

Monthly Cost = Monthly Tokens × Cost per Million Tokens

Inputs

Example input Requests per day: 4,000
Example input Tokens per request: 1,500
Example input Cost per million: $5.50

Outputs

Example result Monthly tokens (M): 180
Example result Monthly cost: $990.00
Example result Annual cost: $11,880.00

Inference spend often looks small per request, but volume compounds quickly once the product reaches steady usage.

Inference budget by request volume

5 of 5 rows

Requests per day	Monthly tokens (M)	Monthly cost
1,500	81	$486.00
2,000	108	$648.00
2,500	135	$810.00
3,500	189	$1,134.00
4,500	243	$1,458.00

Inference budgets usually grow with request volume first, so request volume is the best lever to stress-test in planning.
