AI Token Cost Calculator

As AI becomes central to modern software development, API costs can quietly become one of the largest line items in a product budget. Whether you are building a customer-facing chatbot, a document analysis pipeline, or an internal automation tool, understanding exactly what each model costs per request — and how those costs scale with volume — is essential before you commit to a provider or architecture.

Different models charge separately for input tokens (your prompt) and output tokens (the model's response), and the ratio between them varies dramatically across providers. A long system prompt with a short reply has a very different cost profile than a brief question expecting a lengthy generated report. Our calculator lets you enter any combination of input and output tokens, specify your daily request volume, and instantly see the per-request, daily, monthly, and yearly cost for every major model.

Use the comparison table to identify the most cost-effective model for your specific use case. For high-volume applications, the difference between models can amount to thousands of dollars per month — making provider selection one of the highest-leverage engineering decisions you can make.
