AI Cost Calculators
Token pricing across every major model, GPU cloud cost comparisons, inference latency math, prompt-engineering ROI, and full AI-app unit economics — everything you need to keep an AI product profitable.
Why AI cost modeling is different
Traditional SaaS COGS scale predictably with usage. AI workloads don't: token costs are asymmetric (output tokens cost 3–5× input), context windows compound, the cheapest model for a task changes month-to-month as providers update price lists, and a single power user can cost 100× the median.
The calculators in this hub isolate the levers — model tier, input/output token mix, context length, cache hit rate, fine-tuning vs RAG vs prompting — so you can answer the only question that matters: is my AI product profitable at the 99th-percentile user?
For the deeper framework, see our LLM token cost guide, which walks through input vs output pricing, the four pricing patterns that actually work, and a full margin example for a $20/month consumer AI app.

2026 model tier reference
| Tier | Input / M tokens | Output / M tokens | Best for |
|---|---|---|---|
| Premium reasoning | $3–15 | $15–60 | Final generation, complex reasoning |
| Balanced standard | $0.50–3 | $2.50–12 | Most production traffic |
| Fast / cheap | $0.05–0.40 | $0.20–2.00 | Classification, routing, summarization |
Ratios between tiers are more durable than absolute prices. Re-pull provider pricing once a quarter — every major model has dropped 60–95% over the last 18 months.
