How this is calculated
Providers bill input and output tokens separately, per million tokens (MTok). Cached input tokens — a repeated prompt prefix the provider recognizes — are billed at a discounted rate.
cost = (input_tokens − cached_tokens) × input_rate
+ cached_tokens × cached_rate
+ output_tokens × output_ratePricing is verified against provider pricing pages as of 2026-09-01. AI and cloud pricing changes frequently — confirm the current rate on the provider's own pricing page before budgeting.
Frequently asked questions
What is a token?
A token is the unit LLM providers bill by — roughly 4 characters or ¾ of a word in English. A 1,000-word prompt is typically around 1,300 tokens.
Why are input and output tokens priced differently?
Generating output tokens costs more compute per token than reading input tokens, so providers charge a higher per-token rate for output — often 4-6x the input rate.
What are cached input tokens?
When you send the same prompt prefix repeatedly (a system prompt, long context document), providers can cache it and charge a discounted rate — typically 10% of the standard input rate — on subsequent requests.
How accurate is this estimate?
This calculator uses each provider's published list price. Your actual bill depends on exact tokenization, any volume discounts, and rate changes — check the provider's pricing page for the authoritative current rate.
