How to Use This Calculator
  1. Enter your average Input Tokens per request — roughly 750 words equals 1,000 tokens.
  2. Set average Output Tokens per request based on the length of responses your app generates.
  3. Enter Daily API Requests to reflect your production or expected traffic volume.
  4. Select the Model (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, Llama self-hosted, etc.) to apply real pricing.
  5. Compare Daily Cost, Monthly Cost, and Cost per 1K Requests across models to choose the most cost-effective option.

What each input means

Avg input tokens/request
Average number of input tokens (prompt) per API request. 1000 tokens is roughly 750 words.
Avg output tokens/request
Average number of output tokens (completion) per API request.
Daily API requests
Number of API requests your application makes per day.
Model
Select the model

What each result means

Daily cost ($)
Total daily API or compute cost for the selected model.
Monthly cost ($)
Projected 30-day cost.
Annual cost ($)
Projected 365-day cost.
Cost per 1K requests ($)
Effective cost per 1,000 API requests.
Daily token consumption
Total input + output tokens consumed daily.
Monthly tokens (millions)
Total monthly token usage in millions.
Input cost share (%)
Percentage of total cost attributable to input tokens.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Avg input tokens/request = 1000, Avg output tokens/request = 500, Daily API requests = 100, Model = 0 = 4 input(s) provided
  2. Calculate Daily cost
    0.75 = $0.75
  3. Calculate Monthly cost
    Monthly cost = dailyCost * 30
    22.5 = $22.5
  4. Calculate Annual cost
    Annual cost = dailyCost * 365
    273.75 = $273.75
  5. Calculate Cost per 1K requests
    Cost per 1K requests = dailyRequests > 0
    7.5 = $7.5
