Cursor AI Monthly Cost Planner
Calculate your Cursor AI editor costs and compare Hosted plans vs. using your own API keys.
Average size of files, context, and prompts sent in a request.
Average size of the code or response generated by the AI.
Average rate for the models you use (e.g. Claude 3.5 Sonnet is ~$3.00/1M input, $15.00/1M output).
What is the Cursor AI Monthly Cost Planner?
The Cursor AI Monthly Cost Planner helps developers, teams, and software organizations estimate and optimize their monthly bills for the Cursor AI code editor. Since Cursor offers different subscription tiers (Free, Pro, Business) with specific "fast request" limits, it is easy to run over your monthly allotment. This calculator helps you determine if you should upgrade your plan, buy extra fast request packs, or plug in your own OpenAI/Anthropic API keys to pay per token instead.
How Does the Cursor AI Monthly Cost Planner Work?
1. Select Your Cursor Plan â Choose Free, Pro ($20/mo), or Business ($40/seat/mo).
2. Input Monthly AI Commands â Estimate how many total code generations, chats, and inline edits you execute per month.
3. Toggle API Key Mode â Choose whether to use Cursor's built-in hosting or configure your own custom API key.
4. Define Token Usage (If Using Key) â Set average input and output token lengths alongside your average token cost per million to project your pay-as-you-go bill.
5. View Cost Breakdown & Savings â See your total monthly bill, extra request fees, and compare the net savings of hosted plans vs. API keys.
Formula & Calculation Method
Cursor Plan Rules:
- Free: $0/mo, 50 fast requests/mo.
- Pro: $20/mo, 500 fast requests/mo (unlimited slow requests).
- Business: $40/seat/mo, 800 fast requests/seat/mo.
- Extra Fast Requests: Sold in packages of 500 requests for $20.
Equations:
- Cursor Hosted Cost: Base Subscription Fee + (Ceil(Requests Over Limit / 500) Ã $20)
- Own API Key Cost: Base Subscription Fee (if Pro/Business) + (Monthly Requests à (Average Tokens/Req / 1,000,000) à Cost Per 1M Tokens)
- Net Savings: Absolute difference between Hosted Cost and Own API Key Cost.
Example Calculation
Example: Single developer executing 1,200 monthly AI requests on Cursor Pro.
- Option A: Cursor Hosted (Fast Requests)
- Base Pro Cost = $20 (includes 500 fast requests)
- Requests Over Limit = 1,200 - 500 = 700 requests
- Extra Packs Needed = 700 / 500 = 2 packs (1,000 requests)
- Extra Cost = 2 Ã $20 = $40
- Total Hosted Cost: $60 / month
- Option B: Using Own API Key (e.g. GPT-4o-mini / Claude 3.5 at $3.50/1M tokens)
- Average Tokens per request = 2,000 (1,500 input + 500 output)
- Cost per request = (2,000 / 1,000,000) Ã $3.50 = $0.007
- Monthly API cost = 1,200 Ã $0.007 = $8.40
- Base Pro Subscription = $20
- Total API Key Cost: $28.40 / month
- Winner: Using your own API key saves you $31.60 / month!
