# Newsletter Revenue Planner AI Agent Connect > Newsletter Revenue Planner is a financial forecasting engine built for creators.

Instead of manual spreadsheets, you can ask your agent to run complex revenue scenarios and cohort decay projections instantly. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_jbFWxKGtSas1nxAhdn4HI5Yt87vXyor9EZU0Llh6/ai-agent-connect - **Tags:** newsletter, revenue, forecasting, subscription, profitability ## Description Running a newsletter is as much about unit economics as it is about writing. If you don't know your break-even point or how much a 5% monthly churn rate will hurt your bottom line, you're flying blind. This MCP gives your AI client the math skills to handle your business modeling. You can move past basic estimates and start running actual simulations. Whether you're deciding if a new sponsorship tier is worth the effort or trying to figure out how many paid subscribers you need to cover your software costs, this tool handles the heavy lifting. You can model specific monthly performance, compare different monetization paths, and see how subscriber cohorts lose value over time. It turns your AI agent into a specialized financial analyst that understands the specific levers of the newsletter economy. ## Tools ### analyze_revenue_scenarios Compares different business models to see which one generates more profit. Use this to test different combinations of subscriptions and sponsorships. ### calculate_break_even Finds the minimum number of subscribers you need to cover your costs. It identifies the exact point where you stop losing money and start making it. ### calculate_monthly_performance Calculates your total revenue and net profit for a specific month. It factors in subscriptions, sponsorships, and operating expenses. ### project_cohort_decay Simulates how a specific group of subscribers will churn over time.

After subtracting the $1,000 operating cost, your net revenue is $2,600. ``` **Prompt:** ``` How many subscribers do I need to break even if my subscription is $5, conversion is 2%, I make $500 from sponsorships, and my costs are $2000? ``` **Response:** ``` You need 15,000 subscribers to reach the break-even point. ``` **Prompt:** ``` Project the decay of a cohort of 1000 subscribers with a 5% monthly churn rate over 6 months. ``` **Response:** ``` After 6 months, you will have approximately 735 subscribers remaining. ``` ## Capabilities ### Revenue Modeling Your agent calculates monthly profit and recurring revenue based on your specific conversion and pricing data. ### Break-even Analysis The AI determines the exact subscriber count required to cover your monthly operating expenses. ### Churn Simulation Your agent projects how subscriber groups will diminish over time using specific decay rates. ### Scenario Comparison The AI compares different monetization strategies to show which one yields better margins. ## Use Cases ### Pricing Changes Test how raising your subscription price affects your total monthly revenue and break-even point. ### Sponsorship Planning Calculate how many sponsorship slots you need to sell to cover your monthly operating costs. ### Churn Impact Assessment See how a slight increase in monthly churn rate impacts your total subscriber count over several months. ### Growth Goal Setting Determine exactly how many new subscribers you need to reach a specific monthly profit target. ## Benefits - Replaces manual spreadsheet formulas with direct natural language commands. - Provides instant break-even numbers for new business ideas. - Visualizes subscriber loss through cohort decay projections. - Allows for quick comparison of different monetization models. ## How It Works Connect the MCP to your client and start asking financial questions immediately. 1.
