AI Cost Calculator — Token & API Cost Estimator
$14.97
Stop guessing what your AI bill will be. AI Cost Calculator estimates your monthly API spend across every major provider before you write a single line of code.
– Compare 12 models side by side — OpenAI, Anthropic, Google, DeepSeek, xAI, Mistral, and Qwen — with live monthly, per-request, and yearly costs
– Model prices are editable ballparks — overwrite any price to match the provider’s current pricing page
– Factor in prompt caching discounts and cached-input share to see what caching really saves you
– Save unlimited usage scenarios (dev vs prod, cheap vs flagship) on your device and recall them anytime
– Export the full comparison as CSV for budgets, client quotes, and investor decks
– 100% offline single HTML file — no signup, no API key, your data never leaves your browser
### Know your AI bill before you build
AI API pricing is a maze of per-token rates, caching discounts, and model tiers. Pick the wrong model and a side project quietly becomes a $500/month surprise. AI Cost Calculator turns token math into a number you can plan around — in about sixty seconds.
### Key features
