AI API Cost Calculator for Token Usage and Monthly Budget
Use this AI API cost calculator to estimate token usage, input cost, output cost, monthly API spend, and cost per request with editable pricing.
Calculates input-token cost, output-token cost, and total monthly API budget.
Keeps prices editable because model pricing changes and usage tiers differ.
Works as a neutral worksheet for OpenAI, Gemini, Claude, and other token-priced APIs.
Audience
Builders, agencies, and founders estimating AI feature cost before shipping a model-backed workflow.
Designed for people who need a practical calculation before they compare official sources.

How to use this calculator
Adjust the inputs, review the assumptions, and verify source links before making a decision.
Why this page can earn search clicks
AI API pricing changes often, and real cost depends on the user workload. A search result can show a price table, but it cannot calculate a monthly budget without requests, token counts, and model-specific prices.
How to use the calculator safely
Treat the defaults as examples, not quotes. Open the official pricing page for the provider, copy the current per-million-token prices, and then test best-case and worst-case usage volumes.
FAQ
Is this AI API cost calculator tied to one provider?
No. It works for any provider that prices input and output tokens separately. Use the provider pricing page to enter current prices.
Why are prices editable instead of fixed?
Model prices, cached-input rates, batch discounts, and tiers can change. Editable inputs keep the page useful without pretending that one fixed value is always current.
Does this include hosting, vector database, or app server cost?
No. It estimates model API usage only. Add infrastructure, storage, analytics, and support costs separately when planning gross margin.
