What it does
Enter your expected token usage and this free calculator estimates and compares the monthly API cost across GPT, Claude, and Gemini — so you can see which model is actually cheapest for your specific workload instead of guessing from pricing pages.
Why it matters
Model pricing pages quote per-million-token rates that are hard to translate into “what will this actually cost me.” This tool does that translation for you, instantly, before you commit to building on top of one provider.
