Pricing source date: 2026-06-03 · Build verification: 2026-06-03 · Stale threshold: 30 days. Zapier, Make, and n8n public pricing floors reviewed from official source pages. This estimate normalizes tasks, credits/modules, and executions; confirm current provider pricing before purchase or production commitments.
Estimates the automation-platform layer for agent workflows by modeling app-action fan-out and MCP tool-call accounting separately from LLM token cost.
Formula
zapier_tasks = agent_runs * (app_actions + 2 * mcp_tool_calls); make_credits = agent_runs * make_modules; n8n_executions = agent_runs
Primary source register
Agent workflow platform costs use the MR-X1 automation pricing register. LLM inference is intentionally excluded and should be modeled with agent-loop-cost-calculator.

Diagnostic output
This tool returns Cost classification, Dominant cost driver, Decision threshold, and Sensitivity. Diagnostic focus: Automation-platform fan-out before LLM token spend is added..
