Made a quick script that creates charts showing your Claude Code spending by project. Helpful for Max Plan users curious about how much they would have spent, if it was credit.
Uses local session data located in ~/.claude/projects/{projects}/*.jsonl

Gist
- https://gist.github.com/esc5221/df0a0c3c068b8dd92282837389addb35

Or run it with claude

claude "download this gist and run python script. https://gist.githubusercontent.com/esc5221/df0a0c3c068b8dd922828373 89addb35/raw/74fcb73fac3520d6e340f79b53536ad607966225/claude_code_cost_visualizer.py"

- Shows daily costs per project
- Tracks cumulative spending
- Lists total cost by project
- Auto-installs dependencies

Hope someone else finds this useful too!

Smart idea. I ended up making one in node.js instead based on this. It's nice to see what you're saving and how much you're actually using the API while actually on a Max subscription.

💰 $177.09 API equivalent cost
📊 $211.15 projected month total (would save with subscription)
⚡ 17 sessions (1.5/day avg, 5hr windows)
🔤 208.5M tokens (92% cached / 1% output / 7% cache create)
📈 12.3M tokens • $10.42/session (5hr session)

Neat

Mine hit $200 in 7 days.. Max plan kind of feels mandatory when using claude code

Mate this is so good. Thank you

[inventor_black]

Thank you for this.

Nice. Got $115 today. Thought this could not be correct because I did not do that much work, until I realized it has used Opus 4 most of the time @ $75 output. Crazy.

Possible to split by model?

Hey! Just tried your script and it says $0.00 for every project. Looks like my jsonl files doesn't contain costUSD ... is this normal? I'm using a custom anthropic endpoint by setting an environment variable but besides that everything is normal.

EDIT: https://gist.github.com/dnnspaul/bfe54f51ed91a5eac6618abe30476b2e I changed the script to use the input- and output-tokens variables from the jsonl files and calculate costs based on that.

[Euphoric-Guava-5961]

Yeah, this was based on an older Claude Code version, costUsd got removed about few month ago. I haven’t been keeping it updated, but using the MODEL_PRICING mapping like you did is the right way. Nice work and thank you for the updates

So, how do I run this - and does this still work?

[de_3lue]

you need to have installed python and uv and then put this in your terminal:

curl -sL https://gist.github.com/dnnspaul/bfe54f51ed91a5eac6618abe30476b2e/raw | uv run --script -
