LLM Cost Calculator — Input & Output Tokens

Enter your current model and monthly token usage to compute monthly API cost and compare same-workload alternatives.

Formula: monthly cost = input tokens ÷ 1,000,000 × input rate + output tokens ÷ 1,000,000 × output rate

Worked example (sample rates $3 / $15 per 1M tokens, not a current quote): 10M input + 2M output tokens per month → 10 × $3 + 2 × $15 = $60/month. Cached and batch billing are not part of this calculation yet and are not claimed.
