Calculating Gemini CLI Token Costs for Agentic Vibe Coding

While parallelizing AI workflows with background agents is a massive productivity booster, this “fire and forget” vibe coding introduces a new challenge: keeping track of your LLM API costs. If you want to quickly convert your terminal token usage into actual dollars, I highly recommend using this Gemini CLI Cost Calculator.

Using the Gemini CLI, you get a transparent summary of your token usage at the end of every session:

│  Model                       Reqs   Input Tokens   Cache Reads  Output Tokens │
│  ──────────────────────────────────────────────────────────────────────────── │
│  gemini-2.5-flash-lite         12         73,086         1,950            674 │
│  gemini-3.1-pro-preview        93        363,946     4,728,671          9,516 │
│  gemini-2.5-flash              15         93,993        14,061          4,644 │

The trouble is, just like me, you probably want to know the actual COST, not just the raw token count.

That’s where Aish.li’s Gemini CLI cost tool comes in. You simply copy and paste the terminal output table above directly into the site, and it instantly calculates precisely what your session cost in real currency.

It’s a very useful, purpose-built tool that takes the anxiety out of agentic coding. Now you can vibe without worrying about an unknown price tag at the end of the day.
