How to use this calculator
- Enter the usage values for this specific AI cost scenario.
- Review or edit the pricing fields.
- Keep the pricing reference date accurate.
- Click Calculate and compare daily, monthly, annual, and cost results.
What the result means
The result is a practical operating-cost estimate, not a guaranteed invoice. Use it to compare model choices, production volume, and pricing assumptions.
Cost = usage volume × editable price, then scaled to daily, monthly, and annual projections.
Pricing varies by provider and may change over time. Always verify current official pricing before business decisions.
Example calculation
Use the default values as a sample workload, then replace them with your real logs, expected traffic, retry rate, or user volume.
Tips for better results
- Use measured averages instead of guesses when possible.
- Separate input, output, cached, retry, storage, and fixed costs.
- Update pricing when providers change model rates.
FAQ
What is a token?
A token is a small unit of text processed by an AI model. Costs usually depend on input tokens, output tokens, or generated media units.
How are API costs calculated?
Most API costs are calculated by multiplying usage volume by the provider price, then converting the result into daily, monthly, and annual estimates.
Why include a pricing reference date?
AI pricing changes over time. The reference date makes it clear when the default rates were prepared and when you may need to update them.
Can I edit the default pricing?
Yes. Every price field is editable, so you can use current official pricing, contract pricing, or your own internal estimate.
How accurate is this calculator?
It is a planning estimate. Real invoices may differ because of rounding, caching, free tiers, regional prices, retries, storage, and provider-specific billing rules.
