How it works
Estimate monthly AI API cost from input tokens, output tokens, model pricing, requests, and expected usage. Use the units shown in the calculator and review every assumption before using the result.
Formula
Monthly cost = requests × days × ((input tokens ÷ 1,000,000 × input price) + (output tokens ÷ 1,000,000 × output price)).
Worked example
10,000 daily requests with 1,000 input tokens and 300 output tokens can be modeled against any per-million-token pricing.
Important assumptions
This tool is designed for planning and comparison. Real-world prices, manufacturer ratings, building requirements, lender terms, electrical codes, tolerances, and product specifications can vary.
Frequently asked questions
Is this calculator free?
Yes. It runs in your browser and does not require an account.
Are the results exact?
The math is deterministic for the entered values, but the result depends on inputs and assumptions. Verify safety-critical, financial, code-related, towing, fitment, and manufacturer-specific decisions with authoritative information.
