Cost Calculation Formulas

Monthly LLM Cost

Monthly Tokens = Conversations/Day x Turns/Conversation x Tokens/Turn x 30 Monthly LLM Cost = (Input Tokens x Input Rate + Output Tokens x Output Rate) / 1,000,000

Monthly Platform Cost

Monthly Platform Cost = Base Plan + max(0, (Total Tasks - Included Tasks) x Overage Rate)

Total Monthly Cost

Total Monthly = Platform Cost + LLM Cost + Infrastructure + Integrations + Monitoring

Interactive Cost Scenarios

Scenario 1: Solo Founder - Lead Gen Agent - **Volume:** 500 conversations/month, 3 turns each - **Tokens/turn:** ~1,500 (input + output) - **Model:** GPT-4o-mini - **Platform:** Make Core ($10/mo, 10K ops)

Monthly Tokens = 500 x 3 x 1,500 x 30 = 67.5M tokens LLM Cost = (67.5M x $0.15 + 67.5M x $0.60) / 1M = $50.63 Platform = $10 (Make Core covers 10K ops, need ~15K ops = $15 overage) Infrastructure = $0 (Make Cloud) Total = ~$75/month

Scenario 2: Small Team - Support Agent - **Volume:** 2,000 conversations/month, 4 turns each - **Tokens/turn:** ~2,000 - **Model:** GPT-4o (for complex reasoning) - **Platform:** n8n Cloud Pro ($50/mo, 20K exec)

Monthly Tokens = 2,000 x 4 x 2,000 x 30 = 480M tokens LLM Cost = (480M x $5 + 480M x $15) / 1M = $9,600 Platform = $50 (n8n Cloud Pro covers 20K exec, need ~80K exec = $150 overage) Infrastructure = $0 (n8n Cloud) Total = ~$9,800/month

Scenario 3: Enterprise - Multi-Agent System - **Volume:** 50,000 conversations/month, 5 turns each - **Tokens/turn:** ~3,000 (complex multi-agent) - **Model:** Mix of GPT-4o (orchestrator) + Haiku (workers) - **Platform:** n8n Self-Hosted on AWS

Monthly Tokens = 50,000 x 5 x 3,000 x 30 = 22.5B tokens Orchestrator (GPT-4o): 20% = 4.5B tokens = $22,500 input + $67,500 output Workers (Haiku): 80% = 18B tokens = $4,500 input + $22,500 output LLM Total = $117,000 Platform = $0 (self-hosted) + $200 infra Total = ~$117,200/month

Frequently Asked Questions

A simple FAQ bot costs $20-50/month. A customer support agent with 2,000 conversations/month costs $50-200/month. Enterprise multi-agent systems can cost $500-5,000+/month depending on volume and model choice.

Self-host n8n (free software) + use GPT-4o-mini or Claude Haiku for LLM calls. Infrastructure costs ~$20-50/month for a small VPS. Total can be under $30/month for low-volume agents.

At low volumes (<10K conversations/month), platform fees dominate. At high volumes (>50K conversations), LLM API costs typically exceed platform fees. LLM costs scale linearly with tokens; platform costs often have tiered pricing.

Yes. Estimate: conversations/month x turns/conversation x tokens/turn x 30 days = monthly tokens. Multiply by LLM rates. Add platform base fee + estimated overage. Add ~$20-100 for infrastructure.

GPT-4o-mini and Claude 3.5 Haiku offer the best cost/performance for most tasks. Use GPT-4o/Claude Sonnet only for complex reasoning. Avoid GPT-4o for high-volume simple tasks.
