LLM Economics: AI Cost Calculator

Estimate OpenAI API token spend with cached-input, Batch API, and long-context pricing rules.

Estimate Anthropic Claude API token spend using current model, cache-read, and Batch API rates.

Estimate Google Gemini API token spend with cached-input, Batch, and long-context pricing.

Estimate DeepSeek V4 API token spend using current cache-hit and cache-miss rates.

Rank every cost-reduction opportunity for your LLM workload — Prompt Cache, Batch API, and model switching — by annual savings. See your max saving in seconds.

Work backwards from your monthly AI budget to find the maximum tokens per request your product can afford. Compare models and scenarios to get the most from every dollar.

Calculate the payback period and 12-month net benefit of migrating from one LLM to another. Factor in engineering hours, quality risk, and exact token pricing.

Compare the cost of AI coding tools: Cursor, GitHub Copilot, Windsurf and API-based agents. Find the cheapest option for your engineering team size.

Calculate the right price for your AI SaaS product based on LLM costs, target gross margin, and paying user conversion rate. Never underprice your AI product again.

Calculate gross and net margin for your AI wrapper product. See how LLM cost, Stripe fees, refunds, and CAC affect your unit economics and LTV:CAC ratio.

Model the full monthly cost of running an AI agent product: LLM inference, tool calls, vector queries and memory storage — by DAU, with model-tier routing savings.

Calculate the full cost of your RAG pipeline — embeddings, vector storage and retrieval — and compare Pinecone, Supabase and Weaviate to find the cheapest option.

Calculate how much an AI support bot saves by deflecting tickets, reducing agent headcount, and compare labor savings against AI infrastructure cost.

Calculate MRR, ARR, and gross margin after per-user LLM inference and RAG infrastructure costs.

Calculate AI SaaS customer LTV after LLM inference and RAG costs, then compare LTV with CAC.

Calculate CAC payback after monthly LLM inference and RAG costs reduce customer contribution margin.
