Begin with a workload
Estimate input and output tokens per completed job, then measure a pilot workload using your provider's usage records. Retries, long contexts, search, storage and human support can change unit cost materially.
Keep the free-user subsidy visible
A free tier can create cost before it creates a paying customer. Enter free and paid counts independently and test higher usage scenarios. Conversion rates are assumptions until measured.
Match pricing to the delivery
TypingMind provides a useful comparison for license-based pricing, while Chatbase provides a recurring-software case. Neither reported result is your forecast.
Use dated provider prices
Read the official-source price snapshot, confirm the applicable model and processing tier, then enter the rates. Our calculator does not bill an API or fetch a live quote. Review additional provider charges separately.
