Local Coding Agent vs Copilot vs Cursor: What Each Really Costs
If you already own a capable GPU, a local coding agent costs a few dollars a month in electricity versus $120/year for Copilot Pro or $240/year for Cursor Pro — an immediate win. If you are buying hardware for it, a used RTX 3090 breaks even against Cursor in roughly three years, so buy for privacy and control rather than savings. The economics flip decisively for teams: one shared GPU box undercuts per-seat subscriptions within the first year.

Three ways to pay for AI coding help in 2026: flat subscriptions (Copilot Pro at $10/month, Cursor Pro at $20/month), metered API usage (agent tools like Cline pointed at frontier models — anywhere from $10 to hundreds per month depending on how hard you drive them), and local hardware you own. This page prices all three honestly — including the cases where local loses.
Scope note: this is the subscription comparison. If you're weighing local against per-token API pricing for the same open models, that's a different calculation with its own interactive tool — our local vs cloud AI for coding comparison and the cost calculator cover it.
The numbers side by side
| Cost line | Local (owned 24 GB GPU) | Local (buying used 3090) | Copilot Pro | Cursor Pro | API-metered agent |
|---|---|---|---|---|---|
| Up-front | $0 | ~$700 used | $0 | $0 | $0 |
| Monthly | ~$3–6 electricity | ~$3–6 electricity | $10 | $20 | $10–200+ (usage) |
| Year 1 | ~$50 | ~$760 | $120 | $240 | $120–2,400 |
| Year 3 | ~$150 | ~$860 | $360 | $720 | $360–7,200 |
| Usage caps | None | None | Credit-limited | Rate/credit-limited | Your wallet |
| Code leaves machine | No | No | Yes | Yes | Yes |
Electricity assumes a ~350 W card under load a few hours daily at $0.15/kWh — coding assistants idle most of the time, so real draw is far below gaming duty cycles. Full methodology lives in our electricity cost guide.
Where each option honestly wins
The team math is a different sport
Per-seat pricing scales linearly; hardware doesn't. Ten developers on Copilot Business (~$19/seat) run about $2,280/year, forever. One RTX 4090 box (~$2,000 all-in) running Tabby serves that team's completions — payback inside year one, and the compliance story ("code never leaves the network") comes free. This is the strongest pure-economics case for local coding AI, and it's the one CFOs actually approve. Details and caveats in the local vs cloud for small teams comparison.
The verdict, without spin
- Own a 16–24 GB GPU already? Cancel the subscription, run the setup guide, pocket $120–240/year. There is no counterargument at this tier.
- Buying hardware just for coding AI, solo? The subscription is cheaper for ~3 years. Buy the GPU if privacy, caps, or offline work matter — or if it doubles for other local-AI uses, which shortens the effective payback.
- Team of 5+? Price a shared box before renewing per-seat licenses. The math has quietly flipped.
- Heavy agent user? Hybrid: local daily driver + metered API for the hard problems. Full-time frontier agent use is the most expensive option on this page by an order of magnitude.
The break-even hardware
Both cards below hit the 24 GB tier this page prices: the used 3090 for the shortest payback, the 4090 for speed and warranty.
No hardware? Rent the GPU first
Undecided? A rented 24 GB card costs less than one month of Cursor and answers the question with your own repo.
- RunPod — RTX 4090 ≈ $0.3–0.7/hr, A100/H100 by the hour; serverless per-second billing available
- Vast.ai — Marketplace of hosted GPUs — often the cheapest per hour (interruptible options)
- Lambda — On-demand A100/H100/B200 instances and clusters, per-hour billing

Frequently asked questions
Is a local coding assistant cheaper than GitHub Copilot?
If you already own an 8 GB+ GPU: yes, immediately — a few dollars of electricity replaces $120/year, with no usage caps. If you would buy hardware specifically for it, Copilot stays cheaper for about three years at solo scale, so the purchase case rests on privacy, caps, and the hardware’s other uses.
How much electricity does a local coding assistant use?
Less than people assume: an assistant is idle most of the time and bursts during generation. A 24 GB card serving a few active hours daily lands around $3–6/month at $0.15/kWh — roughly 2–5% of a Cursor subscription. Apple Silicon setups draw dramatically less still.
What does Cursor cost compared to running models locally?
Cursor Pro is $20/month ($240/year) with credit-metered access to its best models. A local Qwen 3.6 27B on hardware you own costs electricity only, is never rate-limited, and keeps code on-device. Cursor buys you frontier quality and zero setup; local buys you unlimited use and privacy — the break-even on a used 3090 bought for the purpose is roughly three years.
When is an API-metered coding agent cheaper than both?
For low, bursty usage: a few agentic sessions a month against a frontier API can cost under $10 while outperforming local models. It becomes the most expensive option as usage grows — daily agent loops burn 50–100K tokens per task. Most cost-aware setups pair a local daily driver with metered API for hard problems.
