Code Cost Calculator

Coding Cost Calc estimates what your Claude Code usage would cost at public API list prices. Core capabilities: • Enter input, output, and cache token counts manually • Drop in a local Claude Code JSONL usage log for instant parsing • Per-token-type cost breakdown for uncached input, output, cache reads, and cache writes • Comparison against Claude Pro, Max, Ultra, ChatGPT Pro (Codex), and Cursor plan prices The calculator works entirely in your browser. No signup, no API key, and no request leaves the page, so your usage data stays on your machine. Choose from current and retired Claude models, toggle fast mode or regional routing multipliers, and scale results for repeated workloads to model long-context and high-volume sessions. The breakdown shows exactly where spending comes from, such as cache reads versus fresh output tokens, making it easier to see which habits drive costs. Prices are dated estimates based on published list rates, not invoices, so use the results for planning and comparison rather than billing reconciliation. Built for developers, engineering managers, and power users who run Claude Code daily and want to understand whether a flat subscription or pay-as-you-go API usage makes more financial sense for their workload.
