Claude Code monthly cost calculator

Project your monthly Anthropic bill. See how much hybrid delegation could save. Decide whether to stay, hybrid, or migrate based on numbers, not vibes.

Updated 2026-05-05. Pricing reflects post-2026-04-22 Anthropic Pro plan reshuffle and current API rates. Hybrid savings model uses the 2026-05-05 r/ClaudeAI 81-vote validation: 217 mechanical tasks, $0.41 on DeepSeek V4 Flash vs about $7 on Sonnet, 17x ratio.

1. Which plan are you on?
Pick the one that matches your current Anthropic subscription. The calculator uses post-April 22 pricing.
2. How many hours per day do you actively run Claude Code?
Active session time. Sleeping or idle terminal does not count.
6 h/day
3. What share of your work is mechanical?
Formatting, classification, summarization, field extraction. Tasks that any cheap model could do, but you currently send to Sonnet anyway.
4. What is your Sonnet to Opus mix?
When you do call Claude, which model handles most of the work?

These numbers are projections, not measurements. Actual costs depend on your specific token mix, cache hit ratio, model routing, and how much each session burns in cache_creation. The Token Book chapter 1 explains how to measure your real spend; the projections here use averages from 800+ verified hours of autonomous Claude Code operation. Hybrid savings assume the cheap side worker is well configured (deny-list CLAUDE.md rule, supervised output review). Do not run unsupervised side-worker output in production.
