How much does an AI coding assistant cost per developer?
Before committing to a model, most engineering leads rolling out AI pair-programming want to work out an AI coding assistant's cost per developer. This page does exactly that with an interactive calculator, so instead of guessing you get a concrete monthly cost grounded in today's provider prices.

Why this isn't trivial
The part people underestimate: developers send large code contexts and trigger many completions a day, so input tokens and request frequency dominate the per-seat cost. In practice the biggest savings come from capping context size and caching repeated file/system prompts, so it is worth modelling before you commit.
How it's calculated
We estimate this by estimating tokens per completion and completions per developer per day, then applying the model's rates and multiplying by working days. 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 is a coding assistant more expensive than a chatbot?+
Code prompts carry large file context and developers fire many requests per hour, inflating input-token spend.
Does prompt caching help here?+
Yes — repeated system and file context can often be cached, cutting input cost substantially.
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.
