Kimi API Cost Calculator

Estimate token, cache and the current web-search charge range for Kimi K3, K2.7 Code and K2.6 before you run a workload. Calculations happen in your browser; no API key or sign-in is required.

Official list prices checked USD, before applicable taxes

Workload inputs

Enter per-request token counts, then multiply by the number of requests.

Total input tokens per request, including any cached portion.
Must be no greater than prompt tokens. A cache hit is not guaranteed.
Generated tokens per request, including reasoning tokens when billed as output.
Use 0 to model an empty run; decimals and negative values are rejected.
Official Kimi pages currently conflict: the Help Center lists $0.004 and the Open Platform guide lists $0.005 per triggered $web_search call. The calculator shows a range and also requires search-result tokens in the prompt field.

Estimated cost

This is published-rate arithmetic, not an observed invoice. When web search is included, totals are a range because two current official sources disagree on the per-call fee.

Cache hit input $0.16 / 1M
Cache miss input $0.95 / 1M
Output $4.00 / 1M

kimi-k2.6 · 262,144-token context window

Total estimated cost $9.55 100 requests at approximately $0.0955 each
Per request $0.0955
Without cache hits $13.50
Estimated cache saving $3.95
Estimated Batch saving $0.00

Within the listed context: 152,144 tokens remain per request.

Cost breakdown for all requests
Component Per request All requests
Cache-miss input $0.0475 $4.75
Cache-hit input $0.0080 $0.80
Output $0.0400 $4.00
Web search $0.00 $0.00
Total $0.0955 $9.55

Method, evidence and limits

Calculation

[(uncached prompt ÷ 1,000,000 × cache-miss rate) + (cached prompt ÷ 1,000,000 × cache-hit rate) + (output ÷ 1,000,000 × output rate)] × Batch factor + web-search calls × $0.004 to $0.005

The per-request result is multiplied by the number of requests. When selected, the 0.60 Batch factor applies to the three token lines. The web-search line is shown as an unresolved official-source range; neither endpoint is selected as the single current rate without a dated live billing observation.

What this estimate does not prove

  • It does not call the Kimi API, inspect an account or predict an actual cache-hit rate.
  • It excludes taxes, currency conversion, membership fees and any unlisted product charges.
  • Tool output can add prompt tokens. Add those tokens to the prompt field.
  • A price estimate does not establish that web search and Batch can be combined in a specific API workflow; check current endpoint and tool compatibility.
  • Context checks use prompt plus output. Leave room for any system messages, tool definitions or reasoning history not already counted.
  • Official prices and supported models can change. Recheck the linked documentation before committing spend.
