What This Skill Does

The Financial Calculator skill provides a robust, professional-grade toolkit for performing complex financial analysis within the OpenClaw environment. It is designed to handle time-value-of-money calculations, retail pricing strategies, and comparative investment modeling. Whether you are an individual planning retirement, a retail store owner calculating markup strategies, or a developer performing investment analysis, this tool offers both a high-speed command-line interface (CLI) for batch processing and a polished, responsive web UI for interactive visual analysis. It simplifies calculations like Future Value (FV), Present Value (PV), Compound Interest, and various retail pricing scenarios, including automated table generation for quick comparisons across different interest rates or timeframes.

Installation

To integrate this skill into your OpenClaw agent, use the package manager command:

clawhub install openclaw/skills/skills/tarigha/financial-calculator

Once installed, ensure your environment has Python 3 installed. The web UI component leverages Flask, which is automatically handled during the initial setup script execution. For CLI usage, simply invoke the provided Python scripts in the skill directory.

Use Cases

• Investment Growth: Project future wealth by adjusting rates and compounding frequencies.
• Business Pricing: Determine optimal selling prices using specific markup percentages to hit profit targets.
• Loan Analysis: Discount future obligations to present-day dollars to assess true value.
• Retail Strategy: Generate automated markdown tables to plan sales events.
• Comparative Analysis: Use the table-generation features to visualize how different interest rates affect long-term compound growth.

Example Prompts

1. "Financial-calculator: What is the future value of a $5,000 investment at 6% annual interest over 15 years compounded monthly?"
2. "Financial-calculator: Create a table showing the future value of a $10,000 investment for 5, 10, and 20 years at interest rates of 3%, 5%, and 8%."
3. "Financial-calculator: If an item costs $45 and I need a 40% markup, what should the final selling price be?"

Tips & Limitations

Always double-check your compounding frequency input; assuming annual compounding instead of monthly can lead to significant variances in long-term projections. While the calculator is highly accurate, it does not account for external variables like inflation, tax implications, or transaction fees. Always verify high-stakes financial projections with a certified advisor before making irreversible investment decisions. The web UI is ideal for real-time adjustments, while the CLI is best suited for scripts or workflows requiring repeatable, automated output.
