Why this isn't trivial
The part people underestimate: GPT and Claude price input and output tokens differently, so the winner flips depending on how output-heavy your support replies are. In practice the biggest savings come from matching the model to your input:output ratio rather than the headline price, so it is worth modelling before you commit.
How it's calculated
We estimate this by applying each model's input and output rates to a typical support conversation and comparing the monthly totals. 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
Is the cheaper model always better here?+
No — weigh quality too, but for routine support the cheaper model often suffices.
Why does the answer depend on my workload?+
Output-heavy bots favor models with low output rates; input-heavy ones favor low input rates.
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.
