Local LLM Hardware vs Cloud API Break-Even Calculator
Calculate the exact monthly token volume threshold (M*) required to break even when self-hosting local LLM hardware versus using commercial cloud APIs. Compare multi-turn agent context costs on our Agent Cost Evolution Calculator or view the Full Model Pricing Table.

* Disclaimer & Footnotes:
Local open-source models and cloud flagship API models differ in capability, context window, and maintenance overhead. This calculator compares financial cost strictly, not model quality or intelligence.
Frequently Asked Questions
Q. Why can't adding more GPUs change a 'never break-even' result?
Every machine has a physical capacity limit based on throughput (TPS) and utilization rate (u). If the maximum monthly output M_max of a single unit is below the break-even threshold M*, the hardware cannot pay for itself over its lifetime. Scaling up hardware increases fixed capital costs and throughput proportionally, keeping the break-even point unchanged.
Q. What hidden costs are often overlooked in local LLM deployments?
Beyond the initial hardware purchase price (H), key factors include: 1) Base electricity and cooling overhead (E_fixed); 2) Facility/hosting and network bandwidth; 3) Maintenance and spare parts; 4) Rapid hardware depreciation (recommended 24-month horizon).
Q. Are local open-weight models equivalent to cloud APIs?
Open-weight models (Llama, Qwen, DeepSeek releases) hold up well on focused coding and domain tasks, but still trail top cloud APIs on multi-turn reasoning and complex instruction following. This calculator sticks to the financial side: cost and TCO only.
