How much does a text-to-sql analytics agent cost per month?

On Claude Sonnet, about $2,270 a month at 1,500 requests a day with the assumptions below. The cheapest model compared here, Gemini 1.5 Flash, runs about $55.28 for the same workload. Your real figure moves with volume and tokens, so tune it in the calculator.

Which model is cheapest for a text-to-sql analytics agent?

Gemini 1.5 Flash, at about $55.28 a month for this workload. Cheaper is not automatically better: a model that needs retries or longer prompts can cost more in practice, so test the candidates on your own evaluation set before committing.

What does a text-to-sql analytics agent cost to run?

An agent that turns plain-English questions into SQL against your schema, runs the query, and explains the result. Schema context is retrieved per request and the query runs as a tool call. On Claude Sonnet this works out to about $2,270 a month; here is the figure across every model and what drives it.

what_drives_it

Where the money goes

Schema retrieval plus the tool loop means context is re-sent a few times per question, so input tokens carry the cost.

The cheapest option here, Gemini 1.5 Flash, comes to about $55.28 a month against $2,270 on Claude Sonnet. Whether the cheaper model fits is a question for your evaluation set, not the price sheet. The bigger lever is usually the workload itself: caching re-sent context, trimming what each turn carries, and capping the tool loop move the bill more than swapping models does.
