How much does output length change my cost?
To see how output length changes per-request cost, you first have to understand how your text maps to tokens. Built for teams tuning response length, this tool makes the token math concrete so your budgets and context planning are based on real numbers.

Why this isn't trivial
The part people underestimate: because output tokens are the priciest, doubling answer length can nearly double the response cost. In practice the biggest savings come from setting sensible max-output limits, so it is worth modelling before you commit.
How it's calculated
We estimate this by pricing different output lengths at the model's output rate. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Should I cap output?+
Usually yes — a max-tokens limit prevents runaway, expensive responses.
Does shorter output hurt quality?+
Not if the answer is complete; trimming padding saves money without loss.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
