AI Inference Budget Calculator
Project monthly AI inference spend from daily request volume and cost per request.
Inputs
Monthly Cost
$3,000.00
Daily Cost
$100.00
Annual Cost
$36,000.00
Monthly Requests
1,500,000requests
Step by step
Monthly requests
50000 × 30
= 1,500,000 requests
Monthly cost
1,500,000 × $0.002000
= $3000.00
How it works
Inference cost is driven by request volume rather than training compute, so budgeting for a production AI feature means projecting daily traffic and multiplying by your per-request cost — which itself depends on model size, average tokens per request, and hosting method. This calculator scales your daily request cost up to monthly and annual figures so you can compare against expected revenue or budget caps before launch.
Formula
monthly_cost = requests_per_day × cost_per_request × days_per_month
- requests_per_day
- Average daily request volume
- cost_per_request
- Cost to serve a single request
- days_per_month
- Days in the billing period
Frequently Asked Questions
How do I find my cost per request?
Use the Cost per Query Calculator to derive cost per request from your model's token pricing and average prompt/completion lengths.
Does traffic vary by day in real deployments?
Yes — this calculator assumes a flat daily average; for spiky or seasonal traffic, model peak-day costs separately to ensure your budget covers worst-case load.
Should I include cold-start or idle infrastructure cost?
No, this figure is purely the marginal cost per served request. Use the AI Deployment Cost Calculator to add fixed infrastructure costs like idle instances or load balancers.
