Frequently asked questions
What does this calculator estimate?
It estimates the all-in monthly cost of an AI code-review agent: LLM tokens consumed per pull request, per-PR platform fees, and human reviewer fallback time for flagged reviews.
How are input tokens calculated?
Input tokens = files per PR × lines per file × tokens per line. We assume output tokens are the generated review comments, summary, and suggestions.
What is cached input?
Repeated code context across runs (e.g., shared codebase context, base branch diffs) may be eligible for provider prompt-cache discounts. Set the percentage that is cached.
Which is cheaper: self-hosted API or a managed code-review platform?
Self-hosted API is cheaper per PR if you already have infrastructure. Managed platforms add per-PR convenience and workflows but raise unit cost; use the platform fee slider to compare.
Should I include human reviewer cost?
Yes, unless the agent auto-approves everything. Human review rate, minutes per review, and hourly cost model the labor saved or added by the agent.
How do I reduce code-review agent cost?
Cache repeated context, limit files reviewed per PR, use a smaller model for first-pass comments, and batch trivial approvals to avoid token consumption.
Prices are approximate per-token list rates as of mid-2026. Platform fees are directional per-PR charges for agentic code-review tools. Treat results as budgeting estimates, not invoices.
