Each input image counts as 1,120 input tokens. 2.1 accepts up to 14.

How this is calculated

Cost per image = image output tokens × the image output rate ÷ 1,000,000, plus the tokens of each add-on × its own rate. Cost per 1,000 images and the monthly total multiply that figure, and nothing is rounded before the last step.

  • Google bills image output in tokens and prints a per-image equivalent on its pricing page. The calculator multiplies the token count by the rate, so a 4K image shows $0.1134 where Google's page prints the rounded $0.113.
  • Token counts per image (1,120 at 1K, 1,680 at 2K, 3,780 at 4K) and all rates are from Google's Gemini API pricing page as read on October 21, 2026.
  • The thinking presets come from our own test of October 14, 2026: eight prompts at 1K, one draw each, 764 to 1,863 thinking tokens with a median of 984. They were measured at 1K only.

Where the numbers come from

Figures and test data are taken from our articles:

Data date: October 21, 2026. Rates change, so check the official pages above before you commit a budget.

Not included

  • Google Search grounding: 5,000 free requests a month shared across Gemini 3.x models, then $14 per 1,000.
  • Prompt text, which adds less than $0.0001 for a prompt of about 60 tokens.
  • Failed or discarded images.
