The Problem
I freelance with n8n and the hardest part isn't building workflows — it's answering the question: "How much should I charge for this?"
There's no tool for it. I Googled. I searched the n8n community. Nothing. Every pricing discussion ends with "it depends."
So I built one.
What It Does
n8n Project Calculator — describe what the client needs and it gives you:
Estimated build cost (flat rate)
Monthly hosting breakdown (self-hosted vs cloud)
Complexity rating so you know what you're walking into
It uses AI to analyze the project requirements and generate a realistic estimate based on n8n-specific factors like node count, integrations, AI agents, and hosting setup.
Stack
Frontend: Next.js (scaffolded with Bolt.new)
Hosting: Vercel (free tier)
AI: DeepSeek API (serverless function)
Monthly cost to run: ~$0
Built in one day. Five rounds of visual review and bug fixing to reach production quality.
Who It's For
Freelancers doing n8n/automation work who need to quote projects
Clients/businesses trying to budget for an automation project
Anyone curious what workflow automation actually costs

Smart niche - automation/n8n freelancers genuinely struggle to price projects, because the cost is hidden in the workflow complexity (how many nodes, how many integrations, error-handling, maintenance) not the obvious surface, and underpricing a "simple automation" that turns into an ops burden is a classic freelancer trap. A calculator that makes the real cost legible up front is exactly the kind of small, sharp tool that a specific audience will actually use and share, which is the best growth loop a niche product has. Building for a community you're part of beats building for "everyone."
The thing that tends to make these calculators sticky: capturing the maintenance/ongoing cost, not just the build estimate - because automations break when an upstream API changes, and the freelancer who priced only the build eats the maintenance. If your calculator surfaces that, it's genuinely differentiated. (Tangentially, the broader pattern you're serving - automation is now cheap enough to be everywhere - is the wave I work on with Moonshift, a multi-agent pipeline that takes a prompt to a deployed SaaS; first run free, no card, if you ever want to build the next tool fast.) Nice focused build. Does the calculator factor in ongoing maintenance/monitoring, or is it scoped to the initial build estimate? The maintenance line is the one freelancers forget and regret.
Thanks! To answer directly — current version covers the
initial build estimate only. Maintenance/monitoring costs
aren't surfaced yet.
You're right though, that's the gap. The freelancer who
quoted a flat build price and then eats the maintenance
is a pattern I've seen too. Good product feedback —
adding a maintenance cost line to the roadmap.
Appreciate the thoughtful comment 🙏
