FAQ

Can I estimate a monthly budget?

Multiply the total cost result by your expected number of similar requests each month.

What if my provider quotes per million tokens?

Convert the price to a per-1K basis by dividing by 1,000 before entering the rate.

Does this include network or storage fees?

No, it focuses solely on tokenized input/output costs.
