Claude Code Cost vs Codex: Plans, API Rates & Team Costs

Claude Code cost vs Codex: subscription prices

These are price comparisons, not equivalent feature bundles. Verify your required models, admin controls, limits, and deployment options on the Claude plan page and Codex plan page. Codex also has limited Free and Go access subject to rollout; this table focuses on the paid coding plans shown above.

If you already pay for a qualifying subscription, test its included coding access first. Buying a second tool creates a new recurring cost; using capacity you already have may not.

How much do Claude Code and Codex cost for 25 developers?

For 25 standard seats, the base budget is the same at the verified rates:

Annual billing reduces this base budget by $125 per month equivalent, or $1,500 over twelve months, relative to paying monthly for all twelve months. The tradeoff is commitment. Pilot the tools before assuming the seat mix will stay fixed.

Illustrative sensitivity: if both tools have a $500 seat base but one adds $150 of separately billed usage and the other adds $400, the totals become $650 and $900. Those extra-usage figures are hypothetical, not vendor forecasts. A difference in actual usage can outweigh a tie in seat price.

Claude Code vs Codex API cost: compare models, not tool names

Neither tool has one universal API token price. The model, service tier, context, and cache behavior determine the applicable rates. Here is a selected rate-card comparison:

Cache-write charges, long-context rates, faster service tiers, and tool charges are outside this table. Check the full Anthropic rate card and OpenAI API pricing. Models listed side by side are not asserted to have equal capabilities.

To isolate the rate difference, suppose a workload uses 1 million ordinary input tokens and 100,000 output tokens, with no cache reads, cache writes, or additional charges:

• Claude Sonnet 5.5: $3.00.
• Claude Opus 5.5: $6.00.
• GPT-6.1 Sol: $3.00.
• GPT-6.1 Terra: $1.50.

This is arithmetic, not a coding benchmark. One model might finish with fewer attempts; another might need more context or review. Measure actual usage on the same acceptance criteria before drawing a cost conclusion.

Why can the monthly bill exceed the subscription price?

A subscription buys access within its terms and limits. Extra credits, API-key sessions, higher-tier seats, and separately billed features can change the total. Some plans include distinct API benefits; apply those only where their eligibility and expiry rules allow. Do not assume a subscription allowance pays every API charge.

For Codex, OpenAI explicitly separates API prices from subscription usage and warns against using token prices to infer included tasks. Model choice, context, reasoning, caching, and speed settings can change allowance consumption. Codex usage and credit rules.

Check consumption in Claude Code with /usage and in the Codex CLI with /status. Our Claude Code usage dashboard guide and Codex usage dashboard guide explain the reporting options.

Which tool costs less per completed task?

Run a small pilot using representative bug fixes, tests, and refactors. Give both tools the same starting repository state and acceptance tests. Record the model, settings, elapsed time, retries, token usage, billed charges, and reviewer effort. Rotate task assignments to reduce the advantage of learning a solution from the first run.

Tool cost per accepted task =
  (allocated subscription fees + incremental usage charges)
  / accepted tasks

Count failed attempts and rework in the numerator. Define acceptance before the pilot: for example, tests pass and a reviewer approves the change. If you include engineering time, report it separately so readers can distinguish tool spend from total delivery cost.

Illustrative example: a $100 tool bill spread across 40 accepted tasks is $2.50 per task. A $150 bill spread across 75 accepted tasks is $2.00 per task. The larger bill can deliver a lower unit cost, but this example is not a measured result for either vendor.

Should you choose Claude Code or Codex on cost?

• For occasional work: start with included access you already pay for and measure whether it meets your needs.
• For daily use: compare the plan tier required to finish your real tasks, including extra charges and review effort.
• For automation: evaluate model-specific API costs and the deployment features your jobs require.
• For teams using both: measure active use before funding duplicate seats for everyone.

AI coding cost tracking with Ganivra puts supported Claude Code and Codex usage into shared developer, team, and project views. Keep estimated token costs separate from your actual bill, then reconcile project allocations to billing records.
