How to Use This Calculator

Enter Tasks per Day — the number of agent jobs your system executes daily.
Set Avg Steps per Task (e.g., 5 for simple tasks, 10–15 for complex reasoning chains) and Tokens per Step.
Enter Tool Calls per Task and Cost per Tool Call to capture external API expenses like web search or code execution.
Set Input Price and Output Price per 1M tokens from your chosen LLM provider's pricing page.
Adjust Retry Rate (%) for expected step failures, then review Cost per Task, Monthly Cost, and Daily Tokens to budget your AI operations.

How the result changes with Avg steps per task

Tasks per day: Number of agent tasks executed per day.
Avg steps per task: Average number of reasoning/action steps the agent takes per task. Simple tasks: 2-3, complex: 8-15.
Tokens per step: Base tokens consumed per agent step (input + output before context growth).
Tool calls per task: Average number of external tool/API calls per task (web search, code execution, etc.).
Cost per tool call ($): Average cost per external tool call (API fees, compute, etc.).
Input price per 1M tokens ($): LLM input token price. GPT-4o: $2.50, Claude Sonnet: $3.
Output price per 1M tokens ($): LLM output token price. GPT-4o: $10, Claude Sonnet: $15.
Retry rate (%): Percentage of steps that require retry due to failures, adding to cost.

Cost per task ($): Total cost per agent task including LLM, tools, and retries.
LLM cost per task ($): Token cost per task (accounts for cumulative context growth across steps).
Tool cost per task ($): External tool/API call cost per task.
Daily cost ($): Total daily agent operating cost.
Monthly cost ($): Projected 30-day agent cost.
Annual cost ($): Projected 365-day agent cost.
Tokens per task: Total tokens consumed per task (input + output with context growth).
Daily tokens (millions): Total daily token consumption in millions.

Identify Input Parameters
4 parameters
Tasks per day = 50, Avg steps per task = 5, Tokens per step = 2000, Tool calls per task = 3 = 8 input(s) provided
Calculate Cost per task
Cost per task = (llmCostPerTask + toolCostPerTask) * retryMultiplier
0.1518 = $0.152
Calculate Monthly cost
Monthly cost = dailyCost * 30
227.7 = $227.7
Calculate LLM cost per task
LLM cost per task = llmInputCostPerTask + llmOutputCostPerTask
0.108 = $0.108
Calculate Tool cost per task
Tool cost per task = toolCallsPerTask * toolCallCost
0.03 = $0.03
