I've been using AI coding tools daily for over a year now. At one point I was paying for Copilot, Cursor, and Claude Code simultaneously. My monthly bill hit $200 before I realized I was using one of them for 90% of my work.
Here's my honest breakdown after 12 months.
What I Actually Use
Claude Code ($20/mo with Pro, or API usage) — This became my daily driver. I run it from the terminal and it handles the tasks I used to waste hours on: refactoring across multiple files, writing tests, debugging deployment configs, reading codebases I didn't write. The key difference is it works with your actual file system, not just the file you have open.
Cursor ($20/mo) — Great for in-editor work. Autocomplete is fast, tab-complete feels natural. I use it when I'm writing new code from scratch and want the IDE experience. But for anything touching more than 2-3 files, I switch to Claude Code.
GitHub Copilot ($19/mo) — I cancelled this. Not because it's bad, but because Cursor does everything Copilot does plus more. The inline chat, the multi-file context, the ability to reference docs — Cursor just does it better for the same price.
The Real Cost Breakdown
Here's where it gets interesting. The subscription price isn't the full picture:

But the real cost is API usage if you're a power user. I hit Cursor's 500 fast request limit by day 12 last month. After that, you're either on slow mode (painful) or paying API rates.
Claude Code on the API is where costs can spike. My heaviest month was $340 in API costs because I was letting it run complex multi-file refactors on a large codebase. Each "subagent" it spawns runs its own API calls.
What Actually Saves Time (and What Doesn't)
Worth every penny:
Generating tests. Writing unit tests for existing code used to take me 2-3 hours per module. Now it's 15 minutes. This alone justifies the subscription.
Debugging error messages. Paste the stack trace, get the fix. Saves 20-30 minutes per bug.
Boilerplate code. API endpoints, database schemas, config files — anything repetitive.
Code review. "Review this PR for security issues" catches things I'd miss.
Not worth the hype:
Writing complex business logic from scratch. The AI gets the structure right but the edge cases wrong. You spend more time fixing than you saved.
"Vibe coding" entire features. Fun for prototypes, terrible for production code. You end up with code you don't understand.
Architecture decisions. AI will confidently suggest patterns that don't fit your constraints.
My Current Setup (Optimized for Cost)
I settled on Cursor Pro ($20/mo) + Claude Code on API (variable):
Cursor for daily in-editor coding, autocomplete, quick questions
Claude Code for heavy lifting: multi-file refactors, codebase analysis, deployment tasks
Total: ~$60-80/mo on average
I use a cheaper model (Sonnet) for Claude Code subagents instead of Opus. Same quality for simple tasks, 5x cheaper. That one config change cut my API bill by 40%.
The Pricing Trap Nobody Talks About
Every AI coding tool advertises the subscription price. None of them advertise the effective cost per productive hour.
Here's my rough calculation:
I code ~160 hours/month
AI tools save me ~30% of that time = 48 hours saved
Total cost: ~$70/month
Effective cost: $1.46/hour saved
That's insane ROI. A junior developer costs $30-50/hour. Even if AI tools only replace 10% of that work, the math is overwhelmingly in favor.
But — and this is the trap — you need to be deliberate about which tool you use for what. Using Opus for a task that Sonnet handles fine is like taking a taxi when the bus goes to the same place.
Calculate Your Own Costs
I built a calculator that compares all major AI coding tools at different usage levels:

And if you're specifically comparing Cursor vs Copilot:

Bottom Line
The best AI coding tool is the one that fits your workflow, not the one with the best benchmarks. I know developers who are more productive with just Copilot than I am with my $70/month stack. The tool matters less than how deliberately you use it.
If you're only going to pay for one tool: Cursor if you want IDE integration, Claude Code if you work in the terminal and do a lot of multi-file work.
What's your AI coding setup? Curious about real-world costs from other developers — especially anyone who's tracked their actual API spending over months.
