Warm cache-read scenario, not general ROI. It excludes cache writes/storage, tools, regional uplifts, retries, and quality failures. A dash means no published cache-read rate.
Gemini API pricing ↗Gemini Developer API and Vertex AI are not interchangeable billing surfaces. These cards retain the documented surface, tier, and effective dates instead of presenting one blended Gemini price.
DATED RATE CARDS
Google prices with their scope intact.
Rates are USD per one million tokens. Future and transitional cards remain labeled with their effective dates instead of silently replacing today’s tier.

USD per 1M tokens. Snapshot verified 2026-08-16. Cache writes, cache storage, tools, regions, and provider-specific thresholds may be billed separately.
A missing cache rate is shown as “—”, never treated as free. Consumer chat-plan quotas are not API prices.
What to verify before shipping
Gemini Developer API and Vertex AI are not interchangeable billing surfaces. These cards retain the documented surface, tier, and effective dates instead of presenting one blended Gemini price.
Price accepted answers, not token deltas
Count retries, fallbacks, tool calls, latency failures, and answers rejected by the quality rubric. A lower estimated token bill is useful only when the workload still succeeds.
Open the controlled A/B labBefore you trust the estimate.
How current are the Google API prices?
This page uses TokenGauge’s 2026-08-16 official-source snapshot. Follow the linked provider pages before making a production commitment because prices can change.
Does this calculator include every Google charge?
No. It models input, output, and a warm cache-read share. Cache writes or storage, tools, retries, regional uplifts, taxes, batch modes, and quality failures can change the final invoice.
Are consumer chat subscriptions included?
No. ChatGPT, Claude, Gemini, Grok, Kimi, and other consumer-plan quotas are separate from provider API token billing.
