AI Cost Calculators

AI API pricing is complex — costs depend on model choice, token counts, request volume, caching strategy, and whether you use batch vs. real-time endpoints. A startup that ships without modeling these numbers often discovers a $5,000/month bill where they expected $200. These calculators give you the real number before you commit. Each tool uses the latest published pricing from provider documentation, updated within 72 hours of any announced change. Whether you're evaluating GPT-4o vs. GPT-4o mini, estimating the break-even point for fine-tuning, or projecting costs per monthly active user, you'll get an honest, formula-transparent answer — not a marketing estimate.
