Why this isn't trivial
The part people underestimate: writing tools are output-heavy, and output tokens usually cost several times more than input, so long drafts dominate the bill. In practice the biggest savings come from generating shorter first drafts and expanding on demand, so it is worth modelling before you commit.
How it's calculated
We estimate this by multiplying words generated per piece by pieces per month, converting to output tokens and applying 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
Why does output length matter so much?+
Generated (output) tokens are the priciest part of most models, so long content drives cost.
Can a cheaper model handle drafting?+
Often yes — first drafts tolerate a budget model, reserving premium models for final polish.
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.
