SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Users need to estimate ongoing model costs without manually tracking every request, so they can forecast budgets and compare scenarios.

Core Features & Use Cases

  • Monthly cost projection: Converts weekly token usage and request volume into an estimated monthly total, daily average, and per-request average.
  • Pricing-aware estimation: Uses model-specific input and output price per million tokens to reflect real billing assumptions.
  • Scenario-friendly assumptions: Supports different input/output token splits and request rates to model alternative usage patterns.

Quick Start

Ask an AI assistant to estimate monthly API spend using 27.2 million weekly tokens, 300 requests per day, a 70/30 input/output split, and the selected model’s current per-million input and output prices.

FAQPage Schema
How do I estimate monthly LLM API spend from weekly token usage?

To estimate monthly LLM API spend, you can project weekly token usage into a monthly total by applying model-specific input and output prices per million tokens. This calculation also produces daily averages and per-request cost breakdowns.

What is the best way to forecast AI model costs for different usage scenarios?

Forecasting AI model costs for different scenarios involves adjusting weekly token volumes, request rates, and input/output token splits. Applying current per-million token pricing to these variables yields a projected monthly total for budget comparison.

Can I compare model pricing options using my own token split assumptions?

Yes, you can compare model pricing options by providing your specific input/output token split and weekly request volume. The estimator applies each model's per-million token rates to generate comparable monthly cost projections.

How do I calculate the average cost per request for token-based API operations?

Calculating the average cost per request for token-based API operations requires dividing the projected monthly total cost by the request volume. This uses your provided weekly token metrics and the model's input/output rates per million tokens.

Do I need to track every individual API request to validate my LLM operations budget?

No, you do not need to track every individual API request to validate your LLM operations budget. You can project monthly run costs by providing aggregate weekly token usage and estimated daily request volume instead.
