Kimi K3 pricing is easiest to understand when you separate four inputs: uncached input tokens, cached input tokens, output tokens, and request volume.
The official pricing page is the source of truth for current rates. Treat any calculator as a planning layer on top of those rates, not as a replacement for your provider invoice.
Start with the official rate card
Before you approve a budget, open the Kimi K3 pricing page and confirm the current input, cached input, and output prices. Providers can update prices, introduce discounts, change rounding rules, or apply taxes by region.
That is why this site keeps price fields editable. A useful Kimi K3 estimate should let you update the rates without rewriting the rest of the model.
Split input, cached input, and output
Long-context Kimi K3 work often reuses the same system prompt, repository notes, policy text, or evaluation rubric. If that stable prefix can be cached, the effective input cost can be much lower than a workflow where every request is fresh.
Output deserves its own line too. Coding agents, research summaries, and report generation can produce long answers. A budget that only estimates input tokens will usually understate real usage.
Convert one request into a monthly plan
After you estimate one request, multiply it by daily calls, active days per month, and retry overhead. Retry overhead matters because tool errors, unclear prompts, and follow-up edits can quietly add extra Kimi K3 calls.
Use the calculator on the homepage to model the shape, then use production logs to replace assumptions with real token counts.
