How this calculator works
The GitHub Copilot vs Cursor Cost Comparator takes one usage profile — agent requests per day, active coding days, average input/output tokens per request and a model tier — and prices it under both platforms' real billing mechanics. For Copilot: monthly requests (requests/day × active days) are multiplied by the model's multiplier to get effective units, anything over the plan's included allowance bills at $0.04/unit, and the total is plan fee + overage. For Cursor: each request's real token cost (input tokens/1M × input price + output tokens/1M × output price) is multiplied by requests/day and active days to get monthly consumption, anything over the plan's credit pool bills as overage at the same rate, and the total is plan price + overage.
At the defaults (25 requests/day, 22 active days, 8,000 in / 800 out tokens, Sonnet-class tier), Copilot Pro's 300-request allowance is blown through by 550 monthly requests × 3x multiplier = 1,650 effective units, so overage kicks in; Cursor Pro's $20 pool absorbs $19.80 of monthly consumption at $0.036/request with room to spare. The two formulas respond to completely different levers — Copilot cares about request count × multiplier, Cursor cares about token count × per-token price — so which one is cheaper flips depending on whether your workload sends many small high-multiplier requests or fewer requests with large token payloads. Use the sweep table to see exactly where that crossover sits for your model tier.
Frequently asked questions
Why isn't a straight price comparison ($10 Pro vs $20 Pro) enough?
Because the two tools don't bill the same thing. Copilot charges a flat plan fee for an allowance of premium requests, then multiplies each request's cost against your allowance by a model multiplier (1x-27x) before charging $0.04 per unit over — so your bill depends on how many requests you send and which model you route them to, not on raw token usage. Cursor instead bills a dollar-denominated credit pool against the real per-request token cost (input tokens/1M x input price + output tokens/1M x output price) — so its bill depends on token counts and per-token model pricing, a completely different mechanic. The sticker prices ($10/$39 vs $20/$60) tell you nothing about which is actually cheaper for a given usage pattern until both formulas are run on the same inputs.
Which tool is cheaper for heavy agent usage?
It depends on your request volume, token size per request and model tier, which is exactly why this calculator runs both formulas on one shared usage profile instead of comparing sticker prices. As a rough pattern: Copilot's multiplier system punishes routing many requests to a high-multiplier frontier model, since the multiplier applies per request regardless of how small that request's actual token count is. Cursor's token-cost system punishes long-context, high-token requests regardless of how many you send, since cost scales with tokens, not request count. A workflow with many small, high-multiplier Copilot requests can look very different from the same request count with large contexts on Cursor — try both extremes in the sweep table below.
Does this include the base subscription fee?
Yes — both totals are the full monthly bill: Copilot's flat plan fee (Pro $10 or Pro+ $39) plus any overage from exceeding the included premium-request allowance at $0.04 per effective unit, and Cursor's flat plan price (Pro $20 or Pro+ $60) plus any overage from exceeding the dollar-denominated credit pool at the real per-request token cost. Neither total assumes you've opted into overage billing by default — check your own account settings, since both platforms cap usage at the included allowance instead of billing further if overage isn't enabled.
What about Windsurf or other AI coding tools?
This comparator only covers GitHub Copilot and Cursor because both have well-documented, stable 2026 billing formulas (model-multiplier allowance vs token-cost credit pool). Windsurf retired its credit system in March 2026 for daily/weekly usage quotas, which isn't a dollar-cost formula this calculator can model the same way — see the general AI coding assistant cost calculator for a broader build-vs-buy view across tools.
