Enter your token volume and see what GPT-4o, Claude, Gemini, and other LLM APIs cost per month
Compare models side by side with up-to-date per-token pricing.
Total Cost = (Input Tokens × Input Rate) + (Output Tokens × Output Rate)
Per-request cost = (input tokens × input rate per 1M) + (output tokens × output rate per 1M). Each model has different rates — for example GPT-4o charges $2.50/$10.00 per 1M tokens. In advanced mode, cached-input and batch discounts are applied before the monthly projection.
It depends on your token volumes and quality needs. Smaller models like GPT-4o mini and Claude Haiku are the most affordable. GPT-4o and Claude 3.5 Sonnet sit in the mid-tier. Use Compare mode in this calculator to run the same workload across models and see ranked costs side by side.
Enter your average input and output tokens per request, then set your expected requests per month. The calculator multiplies per-request cost by that volume to give a monthly projection. Adjust cached-input or batch discounts in advanced mode if your usage qualifies.
Scenario mode loads realistic presets for common workloads — support chat, content generation, and others — so you can start with typical token volumes and tweak from there instead of estimating from scratch.
Yes. Compare mode runs the same token workload across selected models and ranks estimated cost. This helps you evaluate cost tradeoffs before switching providers or model tiers.
