Claude API cost calculator: credits versus a timed plan
Enter the total token usage you expect during a selected plan period and the rates for your actual model and access group. The calculator compares that estimate with the plan’s listed price.

How the estimate works
Estimated token cost = input tokens ÷ 1,000,000 × input rate + output tokens ÷ 1,000,000 × output rate. Enter total usage for the whole period, not a daily total. Rates are USD per million tokens and must come from your current provider or CAK credit group.
This simple estimate excludes cache reads/writes, batch discounts, long-context surcharges, tool charges, taxes and payment fees. If those apply, account for them separately. Tokens are an estimate until the request’s usage record is available.
What the comparison means
| Access period | Listed price | Billing |
|---|---|---|
| Unlimited 1 Hour | $1 | One payment for the selected period |
| Unlimited 24 Hours | $10 | One payment for the selected period |
| Unlimited 1 Week | $49 | One payment for the selected period |
| Unlimited 15 Days | $89 | One payment for the selected period |
The result compares a token-cost scenario with one selected plan. It does not prove that the plan supports your exact model or feature. The Claude Unlimited group currently allows 60 requests per minute; account concurrency and other service limits still apply.
Unused time, a different access group, failed requests or lower usage can change which option suits you. Confirm the current offer and final payment amount on Plans or Top up.
Local calculation
Calculation inputs stay in this browser tab. This tool does not request an API key, send a model request or save your token/rate inputs. Optional site analytics, if you allow them, records page-level acquisition information rather than calculator inputs.
