Vane self-hosting
cost calculator
Estimate your monthly Vane bill from query volume, model choice, and VPS price — plus cost per query and the break-even point against a $20/month subscription.

Estimate your monthly cost
Your inputs are calculated in this browser and saved only in localStorage so a language switch keeps them. Nothing is uploaded; no account is needed. Event logs stay on this device too.
Formula and assumptions
api_month = queries/day × days × (input tokens/1e6 × input price + output tokens/1e6 × output price)
hosting_month = VPS monthly + other monthly
total_month = hosting_month + api_month + hardware cost / depreciation months
per_query = total_month / (queries/day × days)
break_even = ceil(20 / per_query) // cloud API onlyPrice sources: Hetzner · Railway · Hostinger (reference) · Anthropic official · Perplexity Pro; checked 2026-10-21. Not a quote.
What it misses
Taxes, electricity, your time, maintenance, and model quality differences. Those are your call.
Why this exists
Most pages explain how to install Vane; cost is often a static “$4.13–10/month”. This tool lets you change the assumptions to match your usage.
Three numbers to watch
At 100 queries/day, 2,000 input tokens and 500 output tokens per query, and API prices of $2.00/$10.00 per million, model usage is about $27.00/month. Add a $4.13 VPS and you are at about $31.13/month. At 1,000 queries/day, model usage is about $270.00/month.
This is not a quote. It shows that query volume moves the bill much faster than the VPS price.
