How Do You Calculate LLM API Token Cost? (Formula & Step-by-Step Guide)
Primary mathematical equation used by this model:
Cost per Call = (InTokens × InPrice + OutTokens × OutPrice) / 1,000,000
- Enter your daily API requests and average input tokens per call, then set input and output prices for the applicable provider, model and billing terms. Preset buttons load configured example rates and may also change workload inputs; review those values before comparing scenarios.
- Adjust Avg Output Completion Tokens per Call and Input Price ($ per 1M Tokens) to see how the primary result and visual breakdown bar respond in real time.

Frequently Asked Questions — LLM API Token Cost
How do the configured Gemini 2.5 Flash and Flash-Lite example rates compare?
At the configured assumptions of $0.30 per 1M input tokens and $2.50 per 1M output tokens, the Gemini 2.5 Flash example is $445.50/month for 10,000 requests/day with 1,200 input and 450 output tokens over 30 days. At $0.10/$0.40, the Flash-Lite example is $90.00/month for that same workload. These calculations do not verify current prices or supported billing modalities; check https://ai.google.dev/gemini-api/docs/pricing for the applicable terms.
How do prompt length tiers (>200k tokens), Batch API, and Context Caching affect LLM token costs?
Prompt-length tiers, batch processing and caching may change the applicable charges. Check the selected provider’s current terms, enter the input/output rates that apply to your scenario, and account separately for cache storage or other fees this two-rate model does not represent. The calculator does not automatically determine eligibility, tier thresholds or discounts.
How should thinking or reasoning tokens be handled in a cost estimate?
Use the selected provider’s definition of billable input and output tokens. If your model bills thinking or reasoning tokens as output tokens, include those billable tokens in the output-token estimate. If they use a separate rate or fee, account for that separately. This calculator does not determine which internal tokens are billable.
