Prepare Your Data\n - Gather information on monthly infrastructure costs\n - Calculate customer support expenses\n - Estimate continuous development costs\n - Decide on your desired profit margin\n - Determine the estimated number of subscribers\n\n2. Input Values\n - Enter the gathered data into the respective fields in the Prompt node\n - Double-check the accuracy of your inputs\n\n3. Run the Flow\n - Click the \"Run\" button to start the calculation process\n - The flow will use Chain-of-Thought prompting to guide the AI through the steps\n\n4. Review the Results\n - Examine the output in the Chat Output node\n - The result will show a breakdown of costs and the final subscription price\n\n5. Adjust and Refine\n - If needed, modify your inputs to explore different pricing scenarios\n - Re-run the flow to see how changes affect the final price\n\nRemember: Regularly update your costs and

Purpose\nCalculate the optimal monthly subscription price for a software product based on operational costs, desired profit margin, and estimated subscriber base.\n\n## Input Variables\nThe system requires the following inputs:\n- Monthly infrastructure costs (numeric)\n- Customer support costs (numeric)\n- Continuous development costs (numeric)\n- Desired profit margin (percentage)\n- Estimated number of subscribers (numeric)\n\n## Calculation Process\nFollow these steps to determine the subscription price:\n\n### Step 1: Total Monthly Costs\nCalculate the sum of all fixed operational costs:\n```\ntotal_monthly_costs = infrastructure_costs + support_costs + development_costs\n```\n\n### Step 2: Profit Margin Calculation\nCalculate the profit margin amount based on total costs:\n```\nprofit_amount = total_monthly_costs × (profit_margin_percentage / 100)\n```\n\n### Step 3: Total Revenue Required\nCalculate the total monthly revenue needed:\n```\ntotal_revenue_needed = total_monthly_costs + profit_amount\n```\n\n### Step 4: Per-Subscriber Price\nCalculate the minimum price per subscriber:\n```\nsubscription_price = total_revenue_needed ÷ estimated_subscribers\n```\n\n## Output Format\nPresent the results in the following structure:\n\nFixed costs: [sum of all costs]\nProfit margin: [calculated profit amount]\nTotal amount needed: [total revenue required]\nPrice per subscriber: [calculated subscription price]\n\nFinal recommendation: \"The minimum subscription price per subscriber should be [price] to achieve the desired profit margin of [percentage]%\"\n\n## Notes\n- All monetary values should be rounded to 2 decimal places\n- Ensure all input values are positive numbers\n- Validate that the estimated subscribers count is greater than zero\n- The profit margin percentage should be between 0 and 100" }, "temperature": { "_input_type": "SliderInput", "advanced": true, "display_name": "Temperature", "dynamic": false,
